1、普通调用：
public string GetInfo(string url)
{
//访问http方法
string strBuff = "";
Uri httpURL = new Uri(url);
///HttpWebRequest类继承于WebRequest，并没有自己的构造函数，需通过WebRequest的Creat方法建立，并进行强制的类型转换
HttpWebRequest httpReq = (HttpWebRequest)WebRequest.Create(httpURL);
///通过HttpWebRequest的GetResponse()方法建立HttpWebResponse,强制类型转换
HttpWebResponse httpResp = (HttpWebResponse)httpReq.GetResponse();
///GetResponseStream()方法获取HTTP响应的数据流,并尝试取得URL中所指定的网页内容
///若成功取得网页的内容，则以System.IO.Stream形式返回，若失败则产生ProtoclViolationException错误。在此正确的做法应将以下的代码放到一个try块中处理。这里简单处理
Stream respStream = httpResp.GetResponseStream();
///返回的内容是Stream形式的，所以可以利用StreamReader类获取GetResponseStream的内容，并以
//StreamReader类的Read方法依次读取网页源程序代码每一行的内容，直至行尾（读取的编码格式：UTF8）
StreamReader respStreamReader = new StreamReader(respStream, Encoding.UTF8);
strBuff = respStreamReader.ReadToEnd();
return strBuff;
}
方法调用举例：
string url = "http://192.168.1.38:8088/api/user/get_info"; //http协议url
url +="?token=" + token + "&openid=" + openid ;
string userInfo = GetInfo(url);
#region Json访问url方式(使用该方法需要在.net3.5以上)

string Str = GetJson("http://192.168.1.38:8088/api/user/get_info?token=" + token + "&openid=" + openid);
OAuthUser OAuthUser_Model = JsonHelper.ParseFromJson(Str);
return OAuthUser_Model;
}
protected string GetJson(string url)
{
//访问http
WebClient wc = new WebClient();

Response.Write("accesstoken:" + token + "

二、url为https协议
只需加入一句话即可：
//访问https方法（先调用以下方法）
using System.Security.Cryptography.X509Certificates;
public bool CheckValidationResult(object sender, X509Certificate certificate, X509Chain chain, SslPolicyErrors errors)
{
//直接确认，否则打不开
return true;
}
1、普通调用：
public string GetInfo(string url)
{
//访问https方法需加上这句话（CheckValidationResult就是以上方法）
ServicePointManager.ServerCertificateValidationCallback =
new System.Net.Security.RemoteCertificateValidationCallback(CheckValidationResult);
//访问http方法（不需要加上面那句话）
string strBuff = "";
Uri httpURL = new Uri(url);
///HttpWebRequest类继承于WebRequest，并没有自己的构造函数，需通过WebRequest的Creat方法建立，并进行强制的类型转换
HttpWebRequest httpReq = (HttpWebRequest)WebRequest.Create(httpURL);
