Qt-Dropbox-oauth2

Sample application to showcase how to use Qt C++ to authenticate Dropbox apps. I will keep the repo updated as Qt and Dropbox introduces more changes.

Feel free to improve the code and post your issues

Qt-Dropbox-oauth2.pro

Remember to add networkauth in the list of Qt module dependencies

QT += networkauth

dropboxauth.h & dropboxauth.cpp

Please read the comments in the files. I have tried to explain all the details of the code. Remember to edit the APP_KEY, APP_SECRET & port_number (in my case, it is 5476) in dropboxauth.cpp

this->dropbox->setClientIdentifier("APP_KEY");
this->dropbox->setClientIdentifierSharedKey("APP_SECRET");
auto replyHandler = new QOAuthHttpServerReplyHandler(5476, this);

main.cpp

Initialized the dropboxauth object

main.qml

Contains the button which calls the grant() method of Qt and prompts Dropbox auth on the browser

• Dropbox developer console screenshot: Remember to put http://127.0.0.1:your_port instead of http://localhost:your_port else this will result in redirect_uri mismatch error.

Remember, the Redirect URL has to be exactly same as mentioned in the Dropbox developer console
