Python Connecting To An Http Server

In my program, I am trying to access https://api.dropbox.com/1/oauth2/token. In order to do that, I was trying to use http.client.HTTPSConnection(). However, I am receiving a 400 s

Solution 1:

TL;DR: Change the lowercase 'get' to uppercase 'GET' should resolve the problem.

The reason: according to section 5.1.1, RFC2616:

The Method token indicates the method to be performed on the resource identified by the Request-URI. The method is case-sensitive.

RFC2616 also defined 8 methods which are "OPTIONS", "GET", "HEAD", "POST", "PUT", "DELETE", "TRACE", and "CONNECT". All of them are uppercase.

We do know some HTTP clients like python-requests and jQuery.ajax also support lowercase methods but they are just not the standard way defined by the RFC for using those methods. To prevent issues, use uppercase ones first.
