Question

In contact with

Hello everyone who responded to my question.
I want to get a token to use the API in VK. I use java, httpclient library
I send request according to VK documentation.

https://oauth.vk.com/authorize?client_id=1&display=page&redirect_uri=http://example.com/callback&scope=friends&response_type=token&v=5.53

I get to the login page. Tell me how to correctly compose an authorization request in order to receive the token I need in response to work with the VK API ???

I will be grateful for any information!

Answer 1

You don’t need to do it through requests, do it through WebView, but rather use the VK SDK if Android.

Answer 2

Not an android VK SDK will not work. Vopsche really make authorization in VK through httpclient ????
