Similar to this question I am sending the following POST to the server:

content-type: application/x-www-form-urlencoded
authorization: Basic dGVzdGp3dGNsaWVudGlkOlhZN2ttem9OemwxMDA=
accept: */*

With the payload:

{"username"="test", "password": "pw", "email": "test@example.com"}

However, I'm still getting 

{
  "error": "invalid_request",
  "error_description": "Missing grant type"
}

as response from the server. Any idea why this is not working?

Note that the request is working if I use curl:

$ curl testjwtclientid:XY7kmzoNzl100@localhost:8080/oauth/token -d grant_type=password -d username=john.doe -d password=pw -v
*   Trying 127.0.0.1...
* Connected to localhost (127.0.0.1) port 8080 (#0)
* Server auth using Basic with user 'testjwtclientid'

    Your payload should be something like grant_type=password&username=john.doe&password=pw, whereas you are passing it as JSON. You can check https://stackoverflow.com/questions/38165131/spring-security-oauth2-accept-json for JSON payload – Amit K Bist Nov 02 '17 at 21:35
