Brief description
Qt itself provides us with QtSoap, a solution to call WebService. See the source code and examples: qt-solutions-qtsoap

Download and compile
After downloading the source code, you need to modify some places (my version is Qt5), just follow the error prompt to modify it, it's very simple.
After compilation, QtSolutions_SOAP-headd.lib and QtSolutions_SOAP-headd.dll will be generated. . .
use
Copy QtSolutions_SOAP-headd.lib to the lib directory, and copy qtsoap.h to the include directory.
Add library files and library directories in pro:
<span style="color:#000000"><code class="language-Qt">INCLUDEPATH <span style="color:#4f4f4f !important">+=</span> $<span style="color:#4f4f4f !important">$PWD</span>/include

Below, we take "Get Tencent QQ online status" as an example, see: WebXml.com.cn , which contains a large number of Web services, such as: mobile phone number attribution query, email address verification, city weather forecast query, etc.
Example
SOAP 1.1
The following is an example of SOAP 1.1 request and response. The displayed placeholders need to be replaced with actual values.
