wsdl error: no proper separation of headers and document

Question

I\'m using NUSOAP to use a soap interface to microsoftdynamics. I\'m getting this error \"wsdl error: Getting https://testserver2013.api.crm4.dynamics.com/XRMServices/2011/Organ

Answer 1

I just saw this error and it appears to be a bug in the nusoap code. In our case this was caused by a 401 error response to the SOAP call but 301 and 302 responses would appear to trigger the same issue.

The bug appears to be in the following line of code:

if ($pos = strpos($data,"\r\n\r\n"))

When headers were stripped $pos is set to 0 and this evaluates to FALSE whereas it appears the developer intended it to evaluate to TRUE along with the case where the headers are intact.
