每次我尝试通过
检索令牌时curl -L -X POST 'https://www.googleapis.com/oauth2/v4/token?
client_id=oauth2-client-id&
client_secret=oauth2-client-secret&
code=authorization-code&
grant_type=authorization_code&
redirect_uri=https://www.google.com'
(使用我自己的client_id、secret和authorizationcode)我得到一个错误，而不是两个令牌。我通过删除所有内容并创建新项目重新启动了5或6次，但始终得到相同的错误:

谁能帮忙?谢谢你
您需要POST这些参数，而不是将它们作为查询参数发送，因此使用如下内容:
curl -L -d 'client_id=oauth2-client-id' -d 'client_secret=oauth2-client-secret' -d 'code=authorization-code' -d 'grant_type=authorization_code' -d 'redirect_uri=https://www.google.com' https://www.googleapis.com/oauth2/v4/token
在这种形式下，cURL也会自动添加所需的Content-Length请求头。
