c#中http如何post字符串

Answer 1

参数： url： 目标地址

data：要post的数据比如a=1&b=2

public string GetPostString(string url, string data)
{
try
{
byte[] postBytes = Encoding.GetEncoding("utf-8").GetBytes(data);
HttpWebRequest myRequest = (HttpWebRequest)WebRequest.Create(url);
myRequest.Method = "POST";
myRequest.ContentType = "text/html";
myRequest.ContentLength = postBytes.Length;
myRequest.Proxy = null;
Stream newStream = myRequest.GetRequestStream();
newStream.Write(postBytes, 0, postBytes.Length);
newStream.Close();
// Get response
HttpWebResponse myResponse = (HttpWebResponse)myRequest.GetResponse();
using (StreamReader reader = new StreamReader(myResponse.GetResponseStream(), Encoding.GetEncoding("utf-8")))
{
string content = reader.ReadToEnd();
return content;
}
}
catch (System.Exception ex)
{
return ex.Message;
}
}

如果是表单提交的话，把method设置成post就行
