代码如下：

1. 
   
2. using System;
3. using Sy;
4. using Sy;
5. using Sy;
6. using Sy;
7. using Sy;
8. using Sy;
9. using Sy;
10. using Sy.Compression;
11. using Sy.RegularExpressions;
13. namespace HttpWebrequestDemo
14. {
15. class Program
16. {
17. private static readonly string DefaultUserAgent = "Mozilla (compatible; MSIE 6.0; Windows NT 5.2; SV1; .NET CLR 1.1.4322; .NET CLR 2.0.50727)";
19. private static bool CheckValidationResult(object sender, X509Certificate certificate, X509Chain chain, SslPolicyErrors errors)
20. {
21. return true; //总是接受
22. }
24. public static HttpWebResponse CreatePostHttpResponse(string url, IDictionary<string, string> parameters,Encoding charset)
25. {
26. HttpWebRequest request = null;
27. //HTTPSQ请求
28. ServicePoin = new RemoteCertificateValidationCallback(CheckValidationResult);
29. request = WebReque(url) as HttpWebRequest;
30. reque = H;
31. reque = "POST";
32. reque = "application/x-www-form-urlencoded";
33. reque = DefaultUserAgent;
34. //如果需要POST数据
35. if (!(parameters == null || == 0))
36. {
37. StringBuilder buffer = new StringBuilder();
38. int i = 0;
39. foreach (string key in )
40. {
41. if (i > 0)
42. {
43. bu("&{0}={1}", key, parameters[key]);
44. }
45. else
46. {
47. bu("{0}={1}", key, parameters[key]);
48. }
49. i++;
50. }
51. byte[] data = c());
52. using (Stream stream = reque())
53. {
54. (data, 0, da);
55. }
56. }
57. return reque() as HttpWebResponse;
58. }
60. static void Main(string[] args)
61. {
62. string url = ";;
63. Encoding encoding = Encoding.GetEncoding("utf-8");
64. IDictionary<string, string> parameters = new Dictionary<string, string>();
65. ("authuser", "*****");
66. ("authpass", "*****");
67. ("orgkey","*****");
68. ("orgname", "*****");
69. HttpWebResponse response = Program.CreatePostHttpResponse(url,parameters,encoding);
70. //打印返回值
71. Stream stream = re(); //获取响应的字符串流
72. StreamReader sr = new StreamReader(stream); //创建一个stream读取流
73. string html = (); //从头读到尾，放到字符串html
74. Con(html);
75. }
76. }
77. }

HttpWebRequest默认会用代理进行连接，导致获取结果比较慢。解决办法是，配置：

reque = null;

不使用代理，即可。
