asp.net后台用HttpWebRequest模拟post提交

string data = "user={\"id\":1,\"name\":\"asdfg\"}&content=httpwebrequest post json 取值";
HttpWebRequest req = (HttpWebRequest)WebRequest.Create("http://localhost:96583/WebApplication/Default.aspx");
req.Method = "POST";
req.ContentType = "application/x-www-form-urlencoded";
Stream reqstream = req.GetRequestStream();
byte[] b = Encoding.ASCII.GetBytes(data);
reqstream.Write(b, 0, b.Length);
StreamReader responseReader = new StreamReader(req.GetResponse().GetResponseStream(), System.Text.Encoding.UTF8);
string result = responseReader.ReadToEnd();

post过去的参数可以在页面用Request.Params["参数名"]获取 也可以用Request.Forms["参数名"]获取

可以传递多个参数 格式和url参数类似

如示例中传了两个参数 user 和 content
