HttpHelper请求封装基类，支持get请求和POS请求，方便微信开发接口交互，为后面接口交互做准备。

1、HttpHelper帮助基类

[csharp] view plaincopy

1. using System;  
2. using System.Collections.Generic;  
3. using System.IO;  
4. using System.Linq;  
5. using System.Text;  
6. using System.Net;  
7. using System.Net.Security;  
8.   
9. namespace Weixin.Utils  
10. {  
11.     public class HttpHelper  
12.     {  
13.         public static string Post(string url, string paramData)  
14.         {  
15.             return Post(url, paramData, Encoding.UTF8);  
16.         }  
17.   
18.         public static string Post(string url, string paramData, Encoding encoding)  
19.         {  
20.             string result;  
21.   
22.             if (url.ToLower().IndexOf("https", System.StringComparison.Ordinal) > -1)  
23.             {  
24.                 ServicePointManager.ServerCertificateValidationCallback =  
25.                                new RemoteCertificateValidationCallback((sender, certificate, chain, errors) => { return true; });  
26.             }  
27.   
28.             try  
29.             {  
30.                 var wc = new WebClient();  
31.                 if (string.IsNullOrEmpty(wc.Headers["Content-Type"]))  
32.                     wc.Headers.Add("Content-Type", "application/x-www-form-urlencoded");  
33.                 wc.Encoding = encoding;  
34.   
35.                 result = wc.UploadString(url, "POST", paramData);  
36.             }  
37.             catch (Exception e)  
38.             {  
39.                 throw;  
40.             }  
41.   
42.             return result;  
43.         }  
44.   
45.         public static string Get(string url)  
46.         {  
47.             return Get(url, Encoding.UTF8);  
48.         }  
49.   
50.         public static string Get(string url, Encoding encoding)  
51.         {  
52.             try  
53.             {  
54.                 var wc = new WebClient { Encoding = encoding };  
55.                 var readStream = wc.OpenRead(url);  
56.                 using (var sr = new StreamReader(readStream, encoding))  
57.                 {  
58.                     var result = sr.ReadToEnd();  
59.                     return result;  
60.                 }  
61.             }  
62.             catch (Exception e)  
63.             {  
64.                 throw e;  
65.             }  
66.         }  
67.     }  
68. }  

2、帮助类使用

[csharp] view plaincopy

1. var data = "{\"touser\":\"Rich\" },";  
2.         data += "{\"msgtype\": \"text\"},";  
3.         data += "{\"text\": [{\"content\": \"test\"}]}";  
4.         var json = HttpHelper.Post("https://api.weixin.qq.com/cgi-bin/message/custom/send?access_token=" + accessToken, data);  

[csharp] view plaincopy

1. var result = JsonHelper.Deserialize(json);
