SIP网关压力测试工具SIPp的安装及使用详解收藏
SIP网关压力测试工具SIPp的安装及使用详解收藏上一篇介绍了安装Trixbox的过程。
经过简单的测试，pc2pc、pc2phone的通话功能正常。
要把网络电话业务作为商用，就必须要保证系统的稳定和一定的承载能力，所以接下来需要做的是对Asterisk的压力测试，以了解Asterisk在我们的硬件基础上的承载能力。
google一番，发现有一共叫SIPp的软件，专门用于对SIP网关的压力测试，包括注册、通话、多方meeting等并发的压力测试。
以下是从网上搜集并结合我的实际安装过程整理的资料。
SIPp是一个在Linux下运行的软件，为了便于操作，可将其通过Cygwin模拟运行在win32平台下。
第一步，先要安装的是Cygwin，下载地址：/setup.exe 。
该安装文件是在运行过程中再下载相关安装包进行安装的。
第二步，安装。
摘录网友的安装经验：“这方面的文很多，这里只大概谈一下需要注意的地方：1、下载时前面都是下一步就OK，按默认就好。
到选择镜像站点的时候建议选择前面一点的，希望大家不要浪费时间去试验；2、到选择安装方式——Select Packages页面时，一定要注意每个包后面的状态：Keep,意思就是说保持目前已经安装的版本不动。
不会替换目前已有的版本，下次安装包的时候尽量使用此选项，因为它不会把你已经有的包重新安装一次；Curr,意思就是说把最新的版本统统下载下来安装其它2个没试过。
而且应该注意一下名为Category的一列，该列后面写的是安装的方式，有安装、卸载、重新安装等，不用说，第一次当然是安装。
好了，剩下的就是等待了，相信我，这是相当漫长地。
Cygwin就安装完毕，大家一定要记住安装的路径。
”第二步，安装cygwin的IPv6补丁。
地址：http://win6.jp/Cygwin/index.html1、将其解压出来的3个文件夹：/bin,/lib,/usr复制到刚刚Cygwin的安装目录下即：../Cygwin/这里，以替换已有的文件夹。
Asterisk-相关知识与应用
DialPlan (拨号方案)
dial : 它是Asterisk 很有价值的一功能,当来电者使用不同的通信方式时,它可以进行转换并进 行呼叫连接,如SIP电话到PSTN呼叫
Contexts : 拨号方案(DialPlan)进入部分我我们称为Contexts,每个Contexts 有一些extensions(扩展)构成,来实现一系列相关服务。
举一个例子如下: [default]
在extensions.conf 配制文件中, [default]上下文是拨号方案默认的进入部分
DialPlan (拨号方案)
goto 功能是发送呼叫到拨号方案中的其它context部分.
语法: goto(context,extension,priority)
[default] exten => 123,1,Answer() exten => 123,n,Background(main-menu) exten => 1,1,Playback(digits/1)
支持一条线路，只需要增32KB 的带宽，但是需要网络 质量良好。 Asterisk可支持成千的客户端（需要板卡与带宽支持）
asterisk 安装与启动
1从官方网站下载 asterisk-1.2.26.tar包,拷备到LINUX 下的用户目录. 2 用tar xzvf asterisk-1.2.26.tar 解压到当目录. 3 进入 asterisk 目录 执行如下命令
/usr/lib/asterisk/modules/ 这个目录包含所有可以加载Asterisk模块(应用程序\ 编辑器\格式和有用 通道),在Asterisk启运时会加载这些模块(可以编辑 modules.conf).
/var/lib/asterisk 比较重要的是astdb文件与agi-bin目录;astdb包含Asterisk当地数 据库信息. sounds/ 所有声音提示的文件在里面 mohmp3/ 如果配置了音乐保持,应用程序会在这个目录下查找mp3 keys/ 使用公钥和私钥系统认证与一个由RSA数字签名形成的一对等 连接.公钥和私钥的扩展名分别为.pub和.key
Mikrotik RouterOS Winbox 操作手册说明书
Manual:WinboxSummaryWinbox is a small utility that allows administration of Mikrotik RouterOS using a fast and simple GUI. It is a native Win32 binary, but can be run on Linux and Mac OSX using Wine.All Winbox interface functions are as close as possible to Console functions, that is why there are no Winbox sections in the manual.Some of advanced and system critical configurations are not possible from winbox, like MAC address change on an interface.Starting the WinboxWinbox loader can be downloaded directly from the router.Open your browser and enter router's IP address, RouterOS welcome page will be displayed. Click on the link to download winbox.exeWhen winbox.exe is downloaded, double click on it and winbox loader window will pop up:To connect to the router enter IP or MAC address of the router, specify username and password (if any) and click on Connect button. You can also enter the port number after the IP address, separating them with a colon, like this 192.168.88.1:9999. The port can be changed in RouterOS services menu.Note: It is recommended to use IP address whenever possible. MAC session uses network broadcasts and isnot 100% reliable.You can also use neighbor discovery, to list available routers by clicking on [...] button:From list of discovered routers you can click on IP or MAC address column to connect to that router. If you click on IP address then IP will be used to connect, but if you click on MAC Address then MAC address will be used to connect to the router.Note: Neighbor discovery will show also devices which are not compatible with Winbox, like Cisco routersor any other device that uses CDP (Cisco Discovery Protocol)Description of buttons and fields of loader screen•[...] - discovers and shows MNDP (MikroTik Neighbor Discovery Protocol) or CDP (Cisco Discovery Protocol) devices.•Connect - Connect to the router•Save - Save address, login, password and note. Saved entries are listed at the bottom of loader window.•Remove - Remove selected entry from saved list•Tools... - Allows to run various tools: removes all items from the list, clears cache on the local disk, imports addresses from wbx file or exports them to wbx file.•Connect To: - destination IP or MAC address of the router•Login - username used for authentication•Password - password used for authentication•Keep Password - if unchecked, password is not saved to the list•Secure Mode - if checked, winbox will use TLS encryption to secure session•Load Previous Session - if checked, winbox will try to restore all previously opened windows.•Note - description of the router that will be saved to the list.Warning: Passwords are saved in plain text. Anyone with access to your file system will be able to retrievepasswords.It is possible to use command line to pass connect to user and password parameters automatically:winbox.exe [<connect-to> [<login> [<password>]]]For example (with no password):winbox.exe 10.5.101.1 admin ""Will connect to router 10.5.101.1 with username "admin"without password.IPv6 connectivityStarting from v5RC6 Winbox supports IPv6 connectivity. To connect to the routers IPv6 address, it must be placed in square braces the same as in web browsers when connecting to IPv6 server. Example:Winbox neighbor discovery is now capable of discovering IPv6 enabled routers. As you can see from the image below, there are two entries for each IPv6 enabled router, one entry is with IPv4 address and another one with IPv6 link-local address. You can easily choose to which one you want to connect:Interface OverviewWinbox interface has been designed to be intuitive for most of the users. Interface consists of:•Main toolbar at the top where users ca add various info fields, like CPU and memory usage.•Menu bar on the left - list of all available menus and sub-menus. This list changes depending on what packages are installed. For example if IPv6 package is disabled, then IPv6 menu and all it's sub-menus will not be displayed.•Work area - area where all menu windows are opened.Title bar shows information to identify with which router Winbox session is opened. Information is displayed in following format:[username]@[Router's IP or MAC] ( [RouterID] ) - Winbox [ROS version] on [RB model] ([platform]) From screenshot above we can see that user admin is logged into router with IP address 10.1.101.18. Router's ID is MikroTik, currently installed RouterOS version is v5.0beta1, RouterBoard is RB800 and platform is PowerPC.On the Main toolbar's left side is located undo and redo buttons to quickly undo any changes made to configuration. On the right side is located:•winbox traffic indicator displayed as a green bar,•indicator that shows whether winbox session uses TLS encryption•checkbox Hide password. This checkbox replaces all sensitive information (for example, ppp secret passwords)with '*' asterisk symbols.Work Area and child windowsWinbox has MDI interface meaning that all menu configuration (child) widows are attached to main (parent) Winbox window and are showed in work area.Child windows can not be dragged out of working area. Notice in screenshot above that Interface window is dragged out of visible working area and horizontal scroll bar appeared at the bottom. If any window is outside visible work area boundaries the vertical or/and horizontal scrollbars will appear.Child window menu barEach child window has its own toolbar. Most of the windows have the same set of toolbar buttons:•Add - add new item to the list•Remove - remove selected item from the list•Enable - enable selected item (the same as enable command from console)•Disable - disable selected item (the same as disable command from console)•Comment - add or edit comment•Sort - allows to sort out items depending on various parameters. Read more >>Almost all windows have quick search input field at the right side of the toolbar. Any text entered in this field is searched through all the items and highlighted as illustrated in screenshot belowNotice that at the right side next to quick find input filed there is a dropdown box. For currently opened (IP Route) window this dropdown box allows to quickly sort out items by routing tables. For example if main is selected, then only routes from main routing table will be listed.Similar dropdown box is also in all firewall windows to quickly sort out rules by chains.Sorting out displayed itemsAlmost every window has a Sort button. When clicking on this button several options appear as illustrated in screenshot belowExample shows how to quickly filter out routes that are in 10.0.0.0/8 range1.Press Sort button2.Chose Dst.Address from the first dropdown box.3.Chose in form the second dropdown box. "in" means that filter will check if dst address value is in range ofspecified network.4.Enter network against which values will be compared (in our example enter "10.0.0.0/8")5.These buttons are to add or remove another filter to the stack.6.Press Filter button to apply our filter.As you can see from screenshot winbox sorted out only routes that are within 10.0.0.0/8 range.Comparison operators (Number 3 in screenshot) may be different for each window. For example "Ip Route" window has only two is and in. Other windows may have operators such as "is not", "contains", "contains not".Winbox allows to build stack of filters. For example if there is a need to filter by destination address and gateway, then•set first filter as described in example above,•press [+] button to add another filter bar in stack.•set up seconf filter to filter by gateway•press Filter button to apply filters.You can also remove unnecessary filter from the stack by pressing [-] button.Customizing list of displayed columnsBy default winbox shows most commonly used parameters. However sometimes it is needed to see another parameters, for example "BGP AS Path" or other BGP attributes to monitor if routes are selected properly.Winbox allows to customize displayed columns for each individual window. For example to add BGP AS path column:•Click on little arrow button (1) on the right side of the column titles or right mouse click on the route list.•From popped up menu move to Show Columns (2) and from the sub-menu pick desired column, in our case click on BGP AS Path (3)Changes made to window layout are saved and next time when winbox is opened the same column order and size is applied.Detail modeIt is also possible to enable Detail mode. In this mode all parameters are displayed in columns, first column is parameter name, second column is parameter's value.To enable detail mode right mouse click on the item list and from the popupmenu pick Detail modeCategory viewIt is possible to list items by categories. In tis mode all items will be grouped alphabetically or by other category. For example items may be categorized alphabetically if sorted by name, items can also be categorized by type like in screenshot below.To enable Category view, right mouse click on the item list and from the popupmenu pick Show CategoriesDrag & DropIt is possible to upload and download files to/from router using winbox drag & drop functionality.Note: Drag & Drop does not work if winbox is running on Linux using wine. This is not a winbox problem,wine does not support drag & drop.Traffic monitoringWinbox can be used as a tool to monitor traffic of every interface, queue or firewall rule in real-time. Screenshot below shows ethernet traffic monitoring graphs.Item copyThis shows how easy it is to copy an item in Winbox. In this example, we will use the COPY button to make a Dynamic WDS interface into a Static interface.This image shows us the initial state, as you see DRA indicates "D" which means Dynamic:•Double-Click on the interface and click on COPY:•A new interface window will appear, a new name will be created automatically (in this case WDS2)•You can see that the new interface status has changed:•Transferring SettingsOn Windows Vista/7 Winbox settings are stored in: %USERPROFILE%\AppData\Roaming\Mikrotik\Winbox\winbox.cfgSimply copy this file to the same location on the new host.[ Top | Back to Content ]Article Sources and Contributors17 Article Sources and ContributorsManual:Winbox Source: /index.php?oldid=25527 Contributors: Janisk, Marisb, Normis, Nz monkeyImage Sources, Licenses and ContributorsFile:win-web-snap.png Source: /index.php?title=File:Win-web-snap.png License: unknown Contributors: Marisb, SergejsBFile:winbox-loader.png Source: /index.php?title=File:Winbox-loader.png License: unknown Contributors: MarisbImage:Icon-note.png Source: /index.php?title=File:Icon-note.png License: unknown Contributors: Marisb, RouteFile:winbox-loader2.png Source: /index.php?title=File:Winbox-loader2.png License: unknown Contributors: MarisbImage:Icon-warn.png Source: /index.php?title=File:Icon-warn.png License: unknown Contributors: Marisb, RouteFile:winbox-ipv6-loader.png Source: /index.php?title=File:Winbox-ipv6-loader.png License: unknown Contributors: MarisbFile:winbox-ipv6nd.png Source: /index.php?title=File:Winbox-ipv6nd.png License: unknown Contributors: MarisbFile:Winbox-workarea.png Source: /index.php?title=File:Winbox-workarea.png License: unknown Contributors: MarisbFile:winbox-win-child.png Source: /index.php?title=File:Winbox-win-child.png License: unknown Contributors: MarisbFile:win-add.png Source: /index.php?title=File:Win-add.png License: unknown Contributors: MarisbFile:win-remove.png Source: /index.php?title=File:Win-remove.png License: unknown Contributors: MarisbFile:win-enable.png Source: /index.php?title=File:Win-enable.png License: unknown Contributors: MarisbFile:win-disable.png Source: /index.php?title=File:Win-disable.png License: unknown Contributors: MarisbFile:win-comment.png Source: /index.php?title=File:Win-comment.png License: unknown Contributors: MarisbFile:win-sort.png Source: /index.php?title=File:Win-sort.png License: unknown Contributors: MarisbFile:winbox-window-search.png Source: /index.php?title=File:Winbox-window-search.png License: unknown Contributors: MarisbFile:Winbox-window-sort.png Source: /index.php?title=File:Winbox-window-sort.png License: unknown Contributors: MarisbFile:Winbox-window-field.png Source: /index.php?title=File:Winbox-window-field.png License: unknown Contributors: MarisbFile:Winbox-window-detail.png Source: /index.php?title=File:Winbox-window-detail.png License: unknown Contributors: MarisbFile:Winbox-window-category.png Source: /index.php?title=File:Winbox-window-category.png License: unknown Contributors: MarisbFile:Winbox1.jpg Source: /index.php?title=File:Winbox1.jpg License: unknown Contributors: NormisFile:winbox-window-trafmon.png Source: /index.php?title=File:Winbox-window-trafmon.png License: unknown Contributors: MarisbImage:2009-04-02_1241.png Source: /index.php?title=File:2009-04-02_1241.png License: unknown Contributors: NormisImage:2009-04-02_1241_001.png Source: /index.php?title=File:2009-04-02_1241_001.png License: unknown Contributors: NormisImage:2009-04-02_1242.png Source: /index.php?title=File:2009-04-02_1242.png License: unknown Contributors: NormisImage:2009-04-02_1242_001.png Source: /index.php?title=File:2009-04-02_1242_001.png License: unknown Contributors: Normis。

本页内容准备学习eVC我的第一个项目仅仅通过另一个简单的步骤创建项目同中有异制作一个声音暂时先到这里欢迎回到大家非常熟悉的MSDN Pocket PC 开发中心，Larry Roof 和我将在这里轮流为您讲解日益流行的手持设备的编程技巧。
当Larry 带着他的iPAQ 走在大街上寻找无线Internet 接入时，像我这样明智的人正在一边查收电子邮件，一边坐在本地星巴克舒适的椅子上，空间有Volkswagen Beetle 那么大。
这不是开玩笑—西雅图令人神往的咖啡商场正忙于安装11Mbps 的无线Internet 接入点，这意味着我可以一只手拿着double-tall latte 编写这个特别的专栏，另一只手拿着油炸圈饼，同时感谢Office XP 的语音识别功能。
上个月，老好人Larry 准备使用令人崇拜的Visual BASIC 语言阐述开发过程。
您知道—它更像图形冒险程序，而不是真正的编程语言，它包含可爱的小图片和对话框，您可以将它们拖过屏幕。
这次我们将使用真正的编程语言— C++。
不用担心，我们不会仅停留在简单的“Hello World”层面上。
如果您是一位经验丰富的C++ 编码人员，那么您会非常吃惊：将您现有的知识应用于这个令人兴奋的新平台是多么的容易啊！如果您刚刚起步，或者很少接触，那么您也可能印象深刻：编写您的Pocket PC 应用程序是多么的简单啊！如果您有Windows ®开发经验，那么您可能想知道，这个C++ 版本是否是某种“玩具”语言。
它会提供Win32 ®兼容的API 吗？MFC 如何呢？ATL 如何呢？有什么样的调试支持呢？好的，你们都会受到很好的款待。
eVisual C++ ®不是C++ 的简装版本，它是真正的McCoy。
此外，Pocket PC 操作系统也不是玩具—它是真正专业的操作系统，因此您可以认为其中存在许多Win32 API。
Asterisk的连接与管理
Asterisk的管理方法很晚了，刚才稍微看了一下Asterisk的管理方法。
现在想做一个记录。
Asterisk有三种管理方法，最常用的当然是通过asterisk命令进入CLI模式对Asterisk进行管理。
另外还有两种方法：1）用TCP协议，连接到5038端口，然后用AMI命令来管理Asterisk;2）用HTTP协议，连接到8080端口，通过WEB的形式对Asterisk进行管理；下面是基本的URL：http://xxx.xxx.xxx.xxx:8088/static/config/index.html1.Asterisk命令行对应的套接字文件是：/var/run/asterisk/asterisk.ctl管理员可以配置cli_permissions.conf对操作系统用户登录asterisk进行授权。
具体的授权方法就不在这里介绍，有兴趣的人可以看看cli_premissions.conf中的说明。
rasterisk的作用基本上和asterisk –r是一致的，不作特别介绍，只对Asterisk命令进行分2.使用AMI方法AMI方法是通过socket登录到Asterisk中，然后用AMI命令对Asterisk进行管理。
通过这个管理接口，我们可以用某种编程语言开发出自己的Asterisk管理平台。
实际上，很多基于GUI的管理平台也是通过这种方法对Asterisk进行管理。
这种方法的配置文件是：manager.conf3.WEB管理Web管理的配置文件是：http.conf浏览器。
具体的登录路径类似于：http:// xxx.xxx.xxx.xxx:8088/static/config/index.html 使用的帐号密码是manager.conf中定义的帐号密码。

For each process, main calls the PrintMemoryInfo function, passi ng the process identifier. PrintMemoryInfo in turn calls the OpenProcess function to obtain the process handle. If OpenProcess fails, the output sho ws only the process identifier. For example, OpenProcess fails for the Idle and CSRSS processes because their access restrictions prevent user-level code from opening them. Finally, PrintMemoryInfo calls the GetProcessMemoryInfo function to obtain the memory usage informa tion.。

WPF中的视频和音频byxirihanlin幸福像花儿一样开放
WPF中的视频和音频byxirihanlin幸福像花儿一样开放WPF中的视频——（1）WPF的视频支持也是基于MediaPlayer类，以及和它相关的MediaElement和MediaTimeline。
由于MediaPlayer是基于Windows Media Player 10 或更高版本，因此，只要Windows Media Player能播放的视频格式（如.wmv, .avi, .mpg等），在MediaPlayer或MediaElement中都能播放（前提是系统中必须安装Windows Media Player 10 或更高）。
WPF中视频的播放和音频有些相似（在用MediaElement时候），通过设置Source属性为视频文件即可。
如果使用MediaPlayer，由于视频的播放需要显示窗口，而MediaPlayer是为程序代码设计的（不参与UI显示），要显示MediaPlayer加载的媒体，必须使用VideoDrawing或DrawingContext（在（2）中再描述）。
用MediaElement播放视频的代码如下：<Grid><MediaElement Source="C:"Users"Public"Videos"Sample Videos"bear.wmv" Opacity="0.5"><MediaElement.Clip><EllipseGeometry Center="220 220" RadiusX="220" RadiusY="220"/></MediaElement.Clip><youtTransform><RotateTransform Angle="180"/></youtTransform></MediaElement><MediaElement Source="C:"Users"Public"Videos"Sample Videos"bear.wmv" Opacity="0.5"><MediaElement.Clip><EllipseGeometry Center="220 220" RadiusX="220"RadiusY="220"/></MediaElement.Clip></MediaElement></Grid>使用两个MediaElement播放同一个视频文件，其中一个做了180度旋转，显示的效果如下图所示：如果要控制视频的播放，可以与MediaTimeline搭配使用，并用PauseStoryboard、ResumeStoryboad等动作进行控制。

Asterisk 入门教程
Asterisk 入门教程subscriber：加入某个group，从而遵从某一个call restricionsubscriber group：可以使用1种call restriction。
call restriction：将numbering plan中各项取出，各自组成成不同的呼叫限制方案numbering plan:通用，是一个整体的计划，里面包括长途，本地，等各种形式的方案-------------------------------------------------------------以上，用于拨入号码的预处理，实际上是一种过滤，下面才是真正的呼叫处理。
--------------------------------------------------------------route:一种策略，根据号码匹配的模式，选择走哪个trunk。
trunk:实际上做通一个链路，供route选择。
analog的，一个POTS就是一条analog trunkanalog的数量由设备定，ip trunk没有限制数量，并且一个ip trunk连到对方IPPBX后，对方的subscriber 数量是不确定的，由那个IP PBX决定。
Asterisk，开始吧--------------------------------------------------------------什么是asterisk?开源电话平台Asterisk 通过了电话的开源平台。
基本上就是一个软件的PBX。
最初是Digium 公司的Mark Spencer 编写的，这个公司就是他创立的，专门生产并销售Asterisk使用的硬件。
Asterisk 简直就是一场电话的革命。
为什么使用Asterisk？现在电信行业的混乱，因为各种专利技术应用在各种层次的网络上，导致很大的混乱。
Asterisk 就是答案——给电信行业普遍的混乱环境带来秩序的革命。
基于Ubuntu16的Asterisk的安装经验
在Asterisk官网下载最新版的安装包（笔者下载的是asterisk-15.1.3），此时安装包会下载到ubuntu的“下载”文件夹中，可以用命令行：sudo mv asterisk-15-current.tar.gz /usr/src
将其移动到/usr/src目录下，然后“右键-提取到…”，将其解压到当前目录，打开解压得到的文件夹，然后“右键-在终端打开”，执行如下命令来安装必要的库：
sudo su
apt-get -y install linux-headers-$(uname -r) build-essential automake autoconf bison flex libtool libncurses5-dev libssl-dev subversion svn-buildpackage apt-get –y install cvs libgsm1 libgsm1-dev
apt-get –y install sysvconfig
apt-get -y install libxml2 libxml2-dev
有些库安不起就算了，然后就可以进行软件安装工作：
./configure
若出现此图标，则表明安装环境OK，可以进行安装。
然后：
make
会得到：
表示编译成功，可以安装软件，继续输入：make install
至此，asterisk安装完成。
再输入
asterisk -r
表示Asterisk顺利启动。
sip编程开发基础入门
s i p编程开发基础入门(总37页)--本页仅作为文档封面，使用时请直接删除即可----内页可以根据需求调整合适字体及大小--最近在学习SIP协议的相关知识，于是上网搜集了部分内容，主要包括SIP协议的概要介绍，SIP 所涉及到得相关协议，SIP开源软件介绍，SIP基础编程范例。
SIP协议全方位概要介绍转载自：出处：中国电信摘要：SIP协议是NGN中的重要协议，越来越得到业界的重视。
本文通过SIP协议的背景、功能、网络元素、实现机制、以及SIP消息的组成等几个方面对SIP协议做了全方位的概要性介绍，以使读者对SIP有初步的概念和认识。
一、SIP协议的背景和功能SIP（会话初始协议）的开发目的是用来帮助提供跨越因特网的高级电话业务。
因特网电话（IP电话）正在向一种正式的商业电话模式演进，SIP就是用来确保这种演进实现而需要的NGN （下一代网络）系列协议中重要的一员。
SIP是IETF标准进程的一部分，它是在诸如SMTP（简单邮件传送协议）和HTTP（超文本传送协议）基础之上建立起来的。
它用来建立，改变和终止基于IP网络的用户间的呼叫。
为了提供电话业务它还需要结合不同的标准和协议：特别是需要确保传输（RTP），与当前电话网络的信令互连，能够确保语音质量（RSVP），能够提供目录（LDAP），能够鉴权用户（RADIUS）等等。
SIP被描述为用来生成，修改和终结一个或多个参与者之间的会话。
这些会话包括因特网多媒体会议，因特网（或任何IP网络）电话呼叫和多媒体发布。
会话中的成员能够通过多播或单播联系的网络来通信。
SIP支持会话描述，它允许参与者在一组兼容媒体类型上达成一致。
它同时通过代理和重定向请求到用户当前位置来支持用户移动性。
SIP不与任何特定的会议控制协议捆绑。
本质上，SIP提供以下功能：名字翻译和用户定位：无论被呼叫方在哪里都确保呼叫达到被叫方。
执行任何描述信息到定位信息的映射。
确保呼叫（会话）的本质细节被支持。
C#中MessageBox用法大全
C#中MessageBox⽤法⼤全C#中MessageBox⽤法⼤全（附效果图）我们在程序中经常会⽤到MessageBox。
MessageBox.Show()共有21中重载⽅法。
现将其常见⽤法总结如下：1.MessageBox.Show("Hello~~~~");最简单的，只显⽰提⽰信息。
2.MessageBox.Show("There are something wrong!","ERROR");可以给消息框加上标题。
3.if (MessageBox.Show("Delete this user?", "Confirm Message", MessageBoxButtons.OKCancel) == DialogResult.OK){//delete}询问是否删除时会⽤到这个。
4.if (MessageBox.Show("Delete this user?", "Confirm Message", MessageBoxButtons.OKCancel,MessageBoxIcon.Question) == DialogResult.OK) {//delete}可以给MessageBox加上⼀个Icon，.net提供常见的Icon共选择。
5.if (MessageBox.Show("Delete this user?", "Confirm Message", MessageBoxButtons.OKCancel,MessageBoxIcon.Question,MessageBoxDefaultButton.Button2) == DialogResult.OK){//delete}可以改变MessageBox的默认焦点，如下：6.if (MessageBox.Show("Delete this user?", "Confirm Message", MessageBoxButtons.OKCancel,MessageBoxIcon.Question,MessageBoxDefaultButton.Button2,MessageBoxOptions.RtlReading) == DialogResult.OK){//delete}反向显⽰：7.if (MessageBox.Show("Delete this user?", "Confirm Message", MessageBoxButtons.OKCancel, MessageBoxIcon.Question, MessageBoxDefaultButton.Button2, MessageBoxOptions.RightAlign,true) == DialogResult.OK){//delete}添加Help按钮：8.if (MessageBox.Show("Delete this user?", "Confirm Message", MessageBoxButtons.OKCancel, MessageBoxIcon.Question,MessageBoxDefaultButton.Button1, MessageBoxOptions.RtlReading, @"/folder/file.htm") == DialogResult.OK){//delete}指定帮助⽂件的路径，点击即可打开该路径下的帮助⽂件。
Python实现公式图像识别转Latex（Mathpix）
Python实现公式图像识别转Latex（Mathpix）本⽂是⽂本OCR的后续，因为⽤到了公式识别，所以阅读了，编写了⼀份⽐较适合⾃⼰使⽤的公式识别的Python程序，具体代码如下，注意使⽤之前应当去申请开发者ID和KEY其对应的是代码中的APP_ID和APP_KEY后的XXX，在我的代码中加⼊了使⽤次数的限制，但是需要⼿动新建⼀个./count.txt⽂件⽤于初始化使⽤次数，当然在个⼈信息页的Usage下也可以看到 API 的调⽤情况包括时间和次数。
下⾯是代码实现，可以直接拷贝使⽤：import osimport sysimport jsonimport timeimport base64import signalimport win32conimport winsoundimport requestsfrom PIL import ImageGrabimport win32clipboard as wcdef set_clipboard(txt):wc.OpenClipboard()wc.EmptyClipboard()wc.SetClipboardData(win32con.CF_UNICODETEXT, txt)wc.CloseClipboard()env = os.environdefault_headers = {'app_id': env.get('APP_ID', 'XXX'),'app_key': env.get('APP_KEY', 'XXX'),'Content-type': 'application/json'}service = 'https:///v3/latex'format_set = ["text","latex_simplified","latex_styled","mathml","asciimath","latex_list"]format_set_output = ["latex_styled","latex_simplified","text"]count = 0def changeCount(number):filehandle = open("./count.txt","w")filehandle.write(str(number))filehandle.close()def getCount():if not os.path.exists("./count.txt"):return 0else:filehandle = open("./count.txt","r")number = int(filehandle.read())filehandle.close()return numberdef image_uri(filename):image_data = open(filename, "rb").read()return "data:image/jpg;base64," + base64.b64encode(image_data).decode()def latex(args, headers=default_headers, timeout=30):r = requests.post(service,data=json.dumps(args), headers=headers, timeout=timeout)return json.loads(r.text)def sig_handler(signum, frame):sys.exit(0)""" 截图后,调⽤Mathpix 公式识别"""def LatexOcrScreenshots(path="./",ifauto=False):global countif count >= 1000:print("\nThe maximum number of uses has been reached!")changeCount(count)returnif not os.path.exists(path):os.makedirs(path)image = ImageGrab.grabclipboard()if image != None:count += 1changeCount(count)print("\rThe image has been obtained.
