This is a DIY sample code of the qt-labs/qthttpserver lib. In this demo, we start a simple server which response to a GET / POST request, and do a simple http post with json-format body.

please refer to qt-labs/qthttpserver, we check out branch 5.15 for we using Qt5.

Built as instructions, and copy files into our your Qt dirs. QtCreator is always recommended.

Please modify the following line in CMakeLists.txt file, replace Qt5_DIR with your own Qt installation dir.

set(Qt5_DIR D:/Qt/Qt5.12.6/5.12.6/msvc2017_64/lib/cmake/Qt5)

simply as usual,

mkdir build && cd build
cmake ..
make

to start the server,

./server 

open internet browser and try http://127.0.0.1:8888, we can see a message Hello QtHttpServer.

to do a http post, run client

./client

If everything goes well, server will print the posted json body from client and client will print the response message from server.
