HttpWebRequest请求

1.获取token接口

 1 private string gettoken()
 2         {
 3             // 测试环境登陆用户
 4             //string username = "as";
 5             //string password = "as";
 6 
 7             string Token = string.Empty;
 8             try
 9             {
10                 if (string.IsNullOrEmpty(username) && username == null && string.IsNullOrEmpty(password) && password == null)
11                     throw new Exception("调用系统接口：获取token失败 用户名或密码不能发为空！");
12                 var strParm = JsonConvert.SerializeObject(new
13                 {
14                     username = username,
15                     password = password
16                 });
17                 //string url = "http接口地址";    // 测试系统地址
18 
19                 Encoding encode = System.Text.Encoding.Default;
20                 Byte[] arrB = encode.GetBytes(strParm);
21                 HttpWebRequest Request = (HttpWebRequest)HttpWebRequest.Create(url);
22                 Request.Method = "POST";
23                 Request.ContentType = "application/json";  // application/x-www-form-urlencoded
24 
25                 Request.ContentLength = arrB.Length;
26                 //实例化写入请求的参数
27                 using (Stream outStream = Request.GetRequestStream())
28                 {
29                     outStream.Write(arrB, 0, arrB.Length);
30                     outStream.Close();
31                 }
32 
33                 //接受http响应
34                 HttpWebResponse myResponse = Request.GetResponse() as HttpWebResponse;
35                 //读取http返回的数据流
36                 Stream ReceiveStream = myResponse.GetResponseStream();
37 
38                 using (StreamReader reader = new StreamReader(ReceiveStream, Encoding.UTF8))
39                 {
40                     Token = reader.ReadToEnd();
41                     reader.Close();
42                 }
43                 myResponse.Close();
44 
45                 JObject obj = JObject.Parse(Token);
46 
47                 var msg = obj.GetValue("msg").ToString();
48                 if (msg != "操作成功")
49                     throw new Exception(msg);
50 
51                 Token = obj.GetValue("token").ToString();
52             }
53             catch (Exception ex)
54             {
55                 throw ex;
56             }
57             return Token;
58         }

2.获取信息接口+表头token串

 1 private string GetbjMerial(JObject infostr)
 2         {
 3             var apiResult = new ResultMessage();
 4             string result = string.Empty;
 5             try
 6             {
 7                 string url = "http接口地址";    // 测试系统地址
 8 
 9                 var para = JsonConvert.SerializeObject(infostr);
10 
11                 Encoding encode = System.Text.Encoding.Default;
12                 Byte[] arrB = encode.GetBytes(para);
13 
14                 //获取token
15                 string token = this.gettoken();
16 
17                 HttpWebRequest Request = HttpWebRequest.Create(url) as HttpWebRequest;
18                 Request.Method = "POST";
19                 Request.ContentType = "text/plain";  //"application/json";
20                 Request.Headers.Add("Authorization", token);
21                 Request.ContentLength = arrB.Length;
22                 //实例化写入请求的参数
23                 using (Stream outStream = Request.GetRequestStream())
24                 {
25                     outStream.Write(arrB, 0, arrB.Length);
26                     outStream.Close();
27                 }
28 
29                 //接受http响应
30                 HttpWebResponse myResponse = Request.GetResponse() as HttpWebResponse;
31                 //读取http返回的数据流
32                 Stream ReceiveStream = myResponse.GetResponseStream();
33 
34                 using (StreamReader reader = new StreamReader(ReceiveStream, Encoding.UTF8))
35                 {
36                     result = reader.ReadToEnd();
37                     reader.Close();
38                 }
39                 myResponse.Close();
40 
41             }
42             catch (Exception ex)
43             {
44                 throw ex;
45             }
46             return result;
47         }
