.NET MVC后台發送post請求

一、WebRequest方式

　　

//設置請求接口
var request = (HttpWebRequest)WebRequest.Create("http://xxx.com/xxx");
//請求參數
var postData = string.Format("appId={0}&appScreat={1}&channel={2}", appId, appScreat, channel);
var data = Encoding.ASCII.GetBytes(postData);
//請求方式
request.Method = "POST";
//請求頭參數設置
request.Headers.Add("sign", sign);
request.Headers.Add("timestamp", timestamp);
request.Headers.Add("token", token);
request.ContentType = "application/x-www-form-urlencoded";
request.ContentLength = data.Length;

using (var stream = request.GetRequestStream())
{
    stream.Write(data, 0, data.Length);
}
//結果返回
var response = (HttpWebResponse)request.GetResponse();
//轉字符串
var responseString = new StreamReader(response.GetResponseStream()).ReadToEnd();
//轉換為json對象
MXCZUserInfoResponse userInfoResponse = JsonConvert.DeserializeObject<MXCZUserInfoResponse>(responseString);
