C#模拟http 发送post或get请求的简单实例
privatestringHttpPost(stringUrl,stringpostDataStr)
{
HttpWebRequestrequest=(HttpWebRequest)WebRequest.Create(Url);
request.Method="POST";
request.ContentType="application/x-www-form-urlencoded";
request.ContentLength=Encoding.UTF8.GetByteCount(postDataStr);
request.CookieContainer=cookie;
StreammyRequestStream=request.GetRequestStream();
StreamWritermyStreamWriter=newStreamWriter(myRequestStream,Encoding.GetEncoding("gb2312"));
myStreamWriter.Write(postDataStr);
myStreamWriter.Close();
HttpWebResponseresponse=(HttpWebResponse)request.GetResponse();
response.Cookies=cookie.GetCookies(response.ResponseUri);
StreammyResponseStream=response.GetResponseStream();
StreamReadermyStreamReader=newStreamReader(myResponseStream,Encoding.GetEncoding("utf-8"));
stringretString=myStreamReader.ReadToEnd();
myStreamReader.Close();
myResponseStream.Close();
returnretString;
}
publicstringHttpGet(stringUrl,stringpostDataStr)
{
HttpWebRequestrequest=(HttpWebRequest)WebRequest.Create(Url+(postDataStr==""?"":"?")+postDataStr);
request.Method="GET";
request.ContentType="text/html;charset=UTF-8";
HttpWebResponseresponse=(HttpWebResponse)request.GetResponse();
StreammyResponseStream=response.GetResponseStream();
StreamReadermyStreamReader=newStreamReader(myResponseStream,Encoding.GetEncoding("utf-8"));
stringretString=myStreamReader.ReadToEnd();
myStreamReader.Close();
myResponseStream.Close();
returnretString;
}
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CookieContainercookie=newCookieContainer();
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
