云平台云计算大作业

云计算大作业一、实验目的：此次大作业实现了Web网页云平台的部署，数据库的写操作，以及微信公众号的建立以及关联；2.通过实际的部署对云平台有实际深入的了解，体会云平台相对于传统平台的优势；3.培养建立相对复杂系统的能力；二、实验平台：云平台使用的是新浪云，因为使用初期是免费的便于开发。

Web工程用MyEclipse 14建立，数据库采用云平台上的公共Mysql数据库，虽然安全性和稳定性*，但是免费。

微信申请的公众号为订阅号。

本实验网页采用jsp Web工程，微信接口采用php。

三、实验过程：实验参考了大量的网上教程，期中一些为直接引用。

申请云平台：/创建新应用：“控制台”—>“SAE”-->“创建新应用”；依照提示创建新应用。

由于本实验网页采用jsp Web工程，微信接口采用php。

所以分别建立java 1.7 jvm的云平台和php应用，由于是轻应用，所以设置应如下图所示，否则免费额度一天就用光。

如此配置一天要100左右。

二级域名自定义，当然土豪可申请一级域名。

图3：Java 1.7 JVM的建立图4：PHP空应用的建立图5：控制台建立好的平台（域名显示）编辑和添加代码：点击“管理应用”（就是网站的名字），进入管理界面，点击左栏“应用”-->“代码管理”进入如下页面：（之前可能要点击“创建版本”，记不清了）总之，只要看到这样的界面，就点击“编辑代码”，上传你已经编辑好的php的zip包（jvm是war包，具体导出步骤见下文）。

Eclipse导出war包：“file”→”export”→”选择一war形式导出”。

点击上传代码包，选择pHp代码上传。

（java代码因为用带数据，所以开数据库之后才能知道接口修改代码，再上传。

）开启公共数据库：点击左栏“数据库与缓存服务”，选择共享性数据库，相关链接代码：// 使用主库写数据使用SaeUserInfo提供的静态方法获取应用的AccessKey和SecretKey String URL="jdbc:mysql:// ";String username=SaeUserInfo.getAccessKey();String password=SaeUserInfo.getSecretKey();String driver="com.mysql.jdbc.Driver";Class.forName(driver).newInstance();Connection con=DriverManager.getConnection(url,username,password);// 使用从库读数据String URL="jdbc:mysql:// ";// 通过SaeUserInfo提供的静态方法获取应用的access_key和secret_keyString Username=SaeUserInfo.getAccessKey();String Password=SaeUserInfo.getSecretKey();String Driver="com.mysql.jdbc.Driver";Class.forName(Driver).newInstance();Connection con=DriverManager.getConnection(URL,Username,Password);之后上传Java代码。

四、实验部分代码：<?php/*罗网计划*/header('Content-type:text');define("TOKEN", "weixin");$wechatObj = new wechatCallbackapiTest();if (!isset($_GET['echostr'])) {$wechatObj->responseMsg();}else{$wechatObj->valid();}class wechatCallbackapiTest{//验证签名public function valid(){$echoStr = $_GET["echostr"];$signature = $_GET["signature"];$timestamp = $_GET["timestamp"];$nonce = $_GET["nonce"];$token = TOKEN;$tmpArr = array($token, $timestamp, $nonce);sort($tmpArr, SORT_STRING);$tmpStr = implode($tmpArr);$tmpStr = sha1($tmpStr);if($tmpStr == $signature){echo $echoStr;exit;}}//响应消息public function responseMsg(){$postStr = $GLOBALS["HTTP_RAW_POST_DATA"];if (!empty($postStr)){$this->logger("R \r\n".$postStr);$postObj = simplexml_load_string($postStr, 'SimpleXMLElement', LIBXML_NOCDATA);$RX_TYPE = trim($postObj->MsgType);//消息类型分离switch ($RX_TYPE){case "event":$result = $this->receiveEvent($postObj);break;case "text":$result = $this->receiveText($postObj);break;case "image":$result = $this->receiveImage($postObj);break;case "location":$result = $this->receiveLocation($postObj);break;case "voice":$result = $this->receiveVoice($postObj);break;case "video":case "shortvideo":$result = $this->receiveVideo($postObj);break;case "link":$result = $this->receiveLink($postObj);break;default:$result = "unknown msg type: ".$RX_TYPE;break;}$this->logger("T \r\n".$result);echo $result;}else {echo "";exit;}}//接收事件消息private function receiveEvent($object){$content = "";switch ($object->Event){case "subscribe":$content = "欢迎使用罗网微信号\n请回复以下关键字：文本表情单图文多图文音乐\n请按住说话或点击+ 再分别发送以下内容：语音图片小视频我的收藏位置";$content .= (!empty($object->EventKey))?("\n来自二维码场景".str_replace("qrscene_","",$object->EventKey)):"";$content .= "\n\n".'<a href="http://1.132********">罗网计划</a>';break;case "unsubscribe":$content = "取消关注";break;case "CLICK":switch ($object->EventKey){case "COMPANY":$content = array();$content[] = array("Title"=>"罗网计划", "Description"=>"","PicUrl"=>"/weixin/weather/icon/cartoon.jpg", "Url" =>"http://1.132********");break;default:$content = "点击菜单：".$object->EventKey;break;}break;case "VIEW":$content = "跳转链接 ".$object->EventKey;break;case "SCAN":$content = "扫描场景 ".$object->EventKey;break;case "LOCATION":$content = "上传位置：纬度".$object->Latitude.";经度".$object->Longitude;break;case "scancode_waitmsg":if ($object->ScanCodeInfo->ScanType == "qrcode"){$content = "扫码带提示：类型二维码结果：".$object->ScanCodeInfo->ScanResult;}else if ($object->ScanCodeInfo->ScanType == "barcode"){$codeinfo = explode(",",strval($object->ScanCodeInfo->ScanResult));$codeValue = $codeinfo[1];$content = "扫码带提示：类型条形码结果：".$codeValue;}else{$content = "扫码带提示：类型".$object->ScanCodeInfo->ScanType." 结果：".$object->ScanCodeInfo->ScanResult;
