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 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, TemperatureService, provided at my Website at:

The TemperatureService Web service allows you to submit a ZIP in the request, and to receive the current temperature at that location.

Here is the request, soap_1_1_GetTemp.req:

POST /Service/TemperatureService.php HTTP/1.1
Connection: Keep-Alive
Content-Type: text/xml; charset=utf-8
SOAPAction: ""
Content-Length: 100

<?xml version="1.0" encoding="UTF-8"?>
   <zipcode xsi:type="xsd:string">12345</zipcode>

Here is the response I got from my first test:

herong> perl 80 \
   soap_1_1_GetSpeech.req soap_1_1.res

herong> more soap_1_1.res
HTTP/1.1 500 Internal Service Error
Server: Apache/2.4.12 (Win32) PHP/7.0.2
X-Powered-By: PHP/7.0.2
Content-Length: 278
Connection: close
Content-Type: text/xml; charset=utf-8

<?xml version="1.0" encoding="UTF-8"?>
   <faultstring>Bad Request</faultstring>

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.
