C#后端代码访问webapi

方法实现：

 1 public static string PostMoths(string url, object obj_model, Dictionary<string, string> dic = null)
 2         {
 3             string param = JsonConvert.SerializeObject(obj_model);
 4             System.Net.HttpWebRequest request;
 5             request = (System.Net.HttpWebRequest)WebRequest.Create(url);
 6             request.Method = "POST";
 7             request.ContentType = "application/json;charset=UTF-8";
 8             if (dic != null && dic.Count != 0)
 9             {
10                 foreach (var item in dic)
11                 {
12                     request.Headers.Add(item.Key, item.Value);
13                 }
14             }
15             byte[] payload;
16             payload = System.Text.Encoding.UTF8.GetBytes(param);
17             request.ContentLength = payload.Length;
18             string strValue = "";
19             try
20             {
21                 Stream writer = request.GetRequestStream();
22                 writer.Write(payload, 0, payload.Length);
23                 writer.Close();
24                 System.Net.HttpWebResponse response;
25                 response = (System.Net.HttpWebResponse)request.GetResponse();
26                 System.IO.Stream s;
27                 s = response.GetResponseStream();
28                 string StrDate = "";
29                 StreamReader Reader = new StreamReader(s, Encoding.UTF8);
30                 while ((StrDate = Reader.ReadLine()) != null)
31                 {
32                     strValue += StrDate;
33                 }
34             }
35             catch (Exception e)
36             {
37                 strValue = e.Message;
38             }
39             return strValue;
40         }

　　调用代码：

1 Dictionary<string, string> headerDic = new Dictionary<string, string>();
2                         headerDic.Add("version", "1.0");
3                         string a = PostMoths("https://domain.com/api/Token/GetToken", new { str = "***" }, headerDic);
4                         Result r = JsonConvert.DeserializeObject<Result>(a);
5                         if (r.code > 0)
6                         {
7  // todu
