WebService—POST访问http接口

WebService—POST访问http接⼝
⼀、post请求
提交和返回数据都为json格式
统⼀采⽤UTF-8字符编码
1public string Post(string Url, string jsonParas)
2 {
3string strURL = Url;
4//创建⼀个HTTP请求
5 HttpWebRequest request = (HttpWebRequest)WebRequest.Create(strURL);
6//Post请求⽅式
7 request.Method = "POST";
8//内容类型
9 request.ContentType = "application/x-www-form-urlencoded";
10
11//设置参数，并进⾏URL编码
12
13string paraUrlCoded = jsonParas;//System.Web.HttpUtility.UrlEncode(jsonParas);
14
15byte[] payload;
16//将Json字符串转化为字节
17 payload = System.Text.Encoding.UTF8.GetBytes(paraUrlCoded);
18//设置请求的ContentLength
19 request.ContentLength = payload.Length;
20//发送请求，获得请求流
21
22 Stream writer;
23try
24 {
25 writer = request.GetRequestStream();//获取⽤于写⼊请求数据的Stream对象
26 }
27catch (Exception)
28 {
29 writer = null;
30 Console.Write("连接服务器失败!");
31 }
32//将请求参数写⼊流
33 writer.Write(payload, 0, payload.Length);
34 writer.Close();//关闭请求流
35// String strValue = "";//strValue为http响应所返回的字符流
36 HttpWebResponse response;
37try
38 {
39//获得响应流
40 response = (HttpWebResponse)request.GetResponse();
41 }
42catch (WebException ex)
43 {

45 }
46 Stream s = response.GetResponseStream();
47// Stream postData = Request.InputStream;
48 StreamReader sRead = new StreamReader(s);
49string postContent = sRead.ReadToEnd();
50 sRead.Close();
51return postContent;//返回Json数据
52 }
