Qt, gsoap, and SSL
I've got a problem that I can't find a solution to no matter what I try.
What I want to get working:
- Qt to use gsoap to connect to a web service that uses https
Summary of what I've done so far:
- Followed "this guide":http://developer.qt.nokia.com/wiki/How_to_use_gSOAP_with_Qt_for_Web_Service_Client and got the basic gsoap examples to work on Qt
- Installed OpenSSL
- Created a simple program in VS2010 C#, added the same web service, and successfully connects
- Used wireshark to capture packets sent by both my Qt and C# app
From what I captured in wireshark, both apps are communicating with the right server. However, the C# app clearly uses https and get authenticated, while the Qt one uses http and gets rejected. I don't think the problem lies in the gsoap generated files (the soapC.cpp should allow ssl).
I only installed OpenSSL and haven't done anything with it beyond adding its bin to PATH. How do I get Qt to use SSL?? The posts I found relating to Qt and SSL say to configure Qt and nmake it. Can't I just include some libraries in the compile options? I want to avoid configuring as I installed from the QtSDK binary and have no configure.exe.
If in the worst case I do have to configure it, what configuration options do I use? The posts I read all recommended different options. And do I need to do anything else after?? All this loosely related information is driving me nuts
edit: Its definitely due to OpenSSL somehow not being enabled for Qt. I stepped through the stdsoap2 code and it skips over all the OpenSSL parts as they are encased within #ifdef WITH_OPENSSL #endif which is disabled. The question is now, how do I enable it???
I'm about to embark on a Qt gSoap project myself, so I'll be watching this thread. My thought as I read your post was; do you need to build the Qt library with "-openssl" or "-openssl-linked"?
You need to have Qt configured using openssl option.
@./configure -openssl-linked OPENSSL_LIBS='-L/opt/ssl/lib -lssl -lcrypto'@
