我获得以下错误消息:

我还尝试使用对API的curl调用:
curl –k –H "content-type :application/x-www-form-urlencoded" –d "grant_type=client_credentials&client_id=42b214ec-7eaf-4f37-aeb5-ae91057a0e27&client_secret=a232af0e-513e-4a64-9977-410d237dc421&scope=openid" –X POST https://sandbox-oauth.aife.finances.rie.gouv.fr/api/oauth/token

好的,我终于解决了我自己的问题。没有必要使用OAuth的东西。 它分为两个类。这段代码只是为了测试
