c# - 如何创建HTTP发布请求

你好，我是编程新手，所以我的问题可能有点奇怪。我的老板让我创建一个http post请求，使用一个密钥和一条消息来访问我们的客户机。
我已经看过Handle HTTP request in C# Console application这篇文章，但是它不包括我把密钥和消息放在哪里，这样客户端api就知道它是我了。提前感谢你的帮助。

最佳答案

我相信你想要这个：

    HttpWebRequest httpWReq =
    (HttpWebRequest)WebRequest.Create("http://domain.com/page.aspx");

ASCIIEncoding encoding = new ASCIIEncoding();
string postData = "username=user";
postData += "&password=pass";
byte[] data = encoding.GetBytes(postData);

httpWReq.Method = "POST";
httpWReq.ContentType = "application/x-www-form-urlencoded";
httpWReq.ContentLength = data.Length;

using (Stream stream = httpWReq.GetRequestStream())
{
    stream.Write(data,0,data.Length);
}

HttpWebResponse response = (HttpWebResponse)httpWReq.GetResponse();

string responseString = new StreamReader(response.GetResponseStream()).ReadToEnd();
