C#模拟http 发送post或get请求的简单实例

概述privatestringHttpPost(stringUrl,stringpostDataStr){HttpWebRequestrequest=(HttpWebRequest)WebRequest.Create(Url);

private string httpPost(string Url,string postDataStr)     {       httpWebRequest request = (httpWebRequest)WebRequest.Create(Url);       request.Method = "POST";       request.ContentType = "application/x-www-form-urlencoded";       request.ContentLength = EnCoding.UTF8.GetByteCount(postDataStr);       request.cookieContainer = cookie;       Stream myRequestStream = request.GetRequestStream();       StreamWriter myStreamWriter = new StreamWriter(myRequestStream,EnCoding.GetEnCoding("gb2312"));       myStreamWriter.Write(postDataStr);       myStreamWriter.Close();        httpWebResponse response = (httpWebResponse)request.GetResponse();        response.cookies = cookie.Getcookies(response.ResponseUri);       Stream myResponseStream = response.GetResponseStream();       StreamReader myStreamReader = new StreamReader(myResponseStream,EnCoding.GetEnCoding("utf-8"));       string retString = myStreamReader.ReadToEnd();       myStreamReader.Close();       myResponseStream.Close();        return retString;     }      public string httpGet(string Url,string postDataStr)     {       httpWebRequest request = (httpWebRequest)WebRequest.Create(Url + (postDataStr == "" ? "" : "?") + postDataStr);       request.Method = "GET";       request.ContentType = "text/HTML;charset=UTF-8";        httpWebResponse response = (httpWebResponse)request.GetResponse();       Stream myResponseStream = response.GetResponseStream();       StreamReader myStreamReader = new StreamReader(myResponseStream,EnCoding.GetEnCoding("utf-8"));       string retString = myStreamReader.ReadToEnd();       myStreamReader.Close();       myResponseStream.Close();        return retString;     }

在post的时候有时也用的到cookie，像登录163发邮件时候就需要发送cookie，所以在外部一个cookie属性随时保存 cookieContainer cookie = new cookieContainer();

注意：有时候请求会重定向，但我们就需要从重定向url获取东西，像QQ登录成功后获取sID，但上面的会自动根据重定向地址跳转。我们可以用：

request.AllowautoRedirect = false;设置重定向禁用，你就可以从headers的Location属性中获取重定向地址
