解决方案

在 JsonObjectRequest 延长JsonRequest其覆盖 getBody（）方法直接，让您的 getParam（）永远不会调用，我建议你延长 StringRequest 而不是的JsonObjectRequest。

您可以检查这回答的更多细节。

顺便说一句，你另一种选择： Netroid ，即基于排球，都提供了更多的功能

I need to pass an email, a password and a token to access the URL, but it's not working

The JsonObjectRequest is extended JsonRequest which override getBody() method directly, so your getParam() would never invoke, I recommend you extend StringRequest instead of JsonObjectRequest.

your can check this answer for more details.

by the way, you've another choice : Netroid, that based Volley, offered more features at all.
