c# - 如何使用 C# HttpWebRequest 发布原始数据

Question

我正在尝试发出一个 POST 请求，我应该在其中发送原始 POST 数据。

我应该修改哪个属性来实现这一点。

它是 HttpWebRequest.ContentType 属性。如果，那么我应该赋予它什么值。

Answer 1

public static string HttpPOST(string url, string querystring)
{
    HttpWebRequest request = (HttpWebRequest)WebRequest.Create(url);
    request.ContentType = "application/x-www-form-urlencoded"; // or whatever - application/json, etc, etc
    StreamWriter requestWriter = new StreamWriter(request.GetRequestStream());

    try
    {
        requestWriter.Write(querystring);
    }
    catch
    {
        throw;
    }
    finally
    {
        requestWriter.Close();
        requestWriter = null;
    }

    HttpWebResponse response = (HttpWebResponse)request.GetResponse();
    using (StreamReader sr = new StreamReader(response.GetResponseStream()))
    {
        return sr.ReadToEnd();
    }
}
