Vb.Net - 写入的字节超过XML中的内容长度字节

呃，我不断收到一个ProtocolViolationException“要写入流的字节超过指定的Content-Length字节大小。在下面的代码。Vb.Net - 写入的字节超过XML中的内容长度字节

我试过设置Content-Length多种方式没有成功。

Dim url = "https://domain.com" 
Dim req As WebRequest = WebRequest.Create(url) 
req.Method = "POST" 
req.ContentType = "application/xml" 

Dim utf8 As New UTF8Encoding() 
req.ContentLength = utf8.GetByteCount(xml.OuterXml) 

xml.Save(req.GetRequestStream()) // throws the exception 
req.GetRequestStream().Close() 

Dim httpResp As WebResponse = req.GetResponse() 
Dim stReader As StreamReader = New StreamReader(httpResp.GetResponseStream()) 
Dim strResponse As String 

strResponse = stReader.ReadToEnd() 

Console.WriteLine(strResponse)

我试过设置使用xml.OutXML.Length

如果您省略行，会发生什么情况：req.ContentLength = utf8.GetByteCount（xml.OuterXml）？ – CarneyCode 2011-02-19 07:07:59

该API要求我发送有效的Content-Length标头。 – doremi 2011-02-19 07:13:03

与WebClient尝试内容长度，它使代码更容易，它需要的正确的冲洗和处理所有流护理：

Dim xml As New XmlDocument 
xml.LoadXml("<foo>abc</foo>") 
Using client As WebClient = New WebClient 
    client.Headers.Item(HttpRequestHeader.ContentType) = "application/xml" 
    Dim data As Byte() = Encoding.UTF8.GetBytes(xml.OuterXml) 
    Console.WriteLine(Encoding.UTF8.GetString(client.UploadData("https://domain.com", data))) 
End Using
