SOAP 1.1 Request - Content-Length Too Small

This section provides a tutorial example of SOAP 1.1 request to use the GetSpeech Web service provided at xmlme.com. A 'Bad Request' error is received, if Content-Length is not enough to cover the entire XML message in the request.

Now let's use my Perl socket test program to send a SOAP 1.1 request to a public Web service provided at xmlme.com.

xmlme.com provides a public Web service called GetSpeech with SOAP 1.1. GetSpeech reads a phrase from one of Shakespeare's plays from the request and returns speech, speaker, and play in the response. According to the instructions given at http://www.xmlme.com/WSShakespeare.asmx?op=GetSpeech, I prepared by first request sample, soap_1_1_GetSpeech.req:

POST /WSShakespeare.asmx HTTP/1.1
Host: www.xmlme.com
Content-Type: text/xml; charset=utf-8
Content-Length: 100
SOAPAction: "http://xmlme.com/WebServices/GetSpeech"

<?xml version="1.0" encoding="utf-8"?>
<soap:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  xmlns:xsd="http://www.w3.org/2001/XMLSchema"
  xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">
  <soap:Body>
    <GetSpeech xmlns="http://xmlme.com/WebServices">
      <Request>To be, or not to be</Request>
    </GetSpeech>
  </soap:Body>
</soap:Envelope>

Here is the response I got from my first test:

\herong>SocketRequestResponse.pl www.xmlme.com 80 
   soap_1_1_GetSpeech.req soap_1_1.res

\herong>type soap_1_1.res
HTTP/1.1 400 Bad Request
Connection: close
Date: ... 2009
Server: Microsoft-IIS/6.0
X-Powered-By: ASP.NET
X-AspNet-Version: 2.0.50727
Cache-Control: private
Content-Length: 0

The "Bad Request" error was expected, because I put 100 as the "Content-Length" in the request. Here is my guess on what happened to this example:

Now I learned that HTTP servers do pay attention to the "Content-Length" header line in the request. I will provide a better value for "Content-Length" and try again in the next tutorial.
