HttpWebRequest导致响应不以HTTP.Data开始

本文关键字：HTTP Data 开始 响应 HttpWebRequest | 更新日期: 2023-09-27 17:49:55

我正在尝试使用craigslist批量发布以下操作:

HttpWebRequest request = null;
Uri uri = new Uri("https://post.craigslist.org/bulk-rss/post");
request = (HttpWebRequest)WebRequest.Create(uri);
request.Method = "POST";
request.ContentType = "application/x-www-form-urlencoded";
request.ContentLength = FormattedXmlDocument.InnerXml.Length;
using (Stream writeStream = request.GetRequestStream())
{
    UTF8Encoding encoding = new UTF8Encoding();
    byte[] bytes = encoding.GetBytes(FormattedXmlDocument.InnerXml);
    writeStream.Write(bytes, 0, bytes.Length);
}
string result = string.Empty;
request.ProtocolVersion = System.Net.HttpVersion.Version11;
request.KeepAlive = false;
try
{
    using (HttpWebResponse response = (HttpWebResponse)request.GetResponse())
    {
        using (Stream responseStream = response.GetResponseStream())
        {
            using (System.IO.StreamReader readStream = new System.IO.StreamReader(responseStream, Encoding.UTF8))
            {
                result = readStream.ReadToEnd();
            }
        }
    }
}
catch (Exception exp)
{
    // MessageBox.Show(exp.Message);
}

当执行这行代码时

using (HttpWebResponse response = (HttpWebResponse)request.GetResponse())

我得到了异常:

The remote server returned an error: (500) Internal Server Error.

我使用fiddler检查请求，它得到以下错误:

Response does not start with HTTP.Data:

和包看起来像这样:

POST https://post.craigslist.org/bulk-rss/post HTTP/1.1
Content-Type: application/x-www-form-urlencoded
Host: post.craigslist.org
Content-Length: 739

HttpWebRequest导致响应不以HTTP.Data开始

写入request.GetRequestStream()将开始向服务器发送数据。
