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, TemperatureService, provided at my Website at: https://www.herongyang.com/Service/TemperatureService.php.
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 Host: www.herongyang.com Connection: Keep-Alive Content-Type: text/xml; charset=utf-8 SOAPAction: "" Content-Length: 100 <?xml version="1.0" encoding="UTF-8"?> <SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/" xmlns:ns1="urn:xmethods-Temperature-Demo" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:SOAP-ENC="http://schemas.xmlsoap.org/soap/encoding/" SOAP-ENV:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/"> <SOAP-ENV:Body> <ns1:getTemp> <zipcode xsi:type="xsd:string">12345</zipcode> </ns1:getTemp> </SOAP-ENV:Body> </SOAP-ENV:Envelope>
Here is the response I got from my first test:
herong> perl SocketRequestResponse.pl www.herongyang.com 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"?> <SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/"> <SOAP-ENV:Body> <SOAP-ENV:Fault> <faultcode>SOAP-ENV:Client</faultcode> <faultstring>Bad Request</faultstring> </SOAP-ENV:Fault> </SOAP-ENV:Body> </SOAP-ENV:Envelope>
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.
