Spring Oauth2.0 Missing grant type
问题 I am using Spring Oauth 2.O. When I pass request as a form-data it works fine, but when I try to pass data in application/json format it gives me error missing grant type. Request http://localhost:8080/oauth/token {"username":"parths","password":"123456","grant_type":"password"} Error I getting. { "status": "0", "message": "Missing grant type" } Please Guide. 回答1: OAuth2 doesn't support JSON in the access token request.You can check here for description..It requires application/x-www-form
