尝试使用刷新令牌时oauth2.0无效请求

Question

使用谷歌oauth2游乐场:https ://developers.google.com/oauthplayground/关注:https://developers.google.com/accounts/docs/OAuth2WebServer#offline

为什么我收到无效请求？

POST /o/oauth2/token HTTP/1.1
Host: accounts.google.com
Content-length: 209
Content-type: application/x-www-form-urlencoded
Authorization: OAuth ya29.XXXXXXXX

client_id=XXXXXXXXX&
client_secret=XXXXXXXXX&
refresh_token=1/0ffkj5lggn8XXXXXXXXX&
grant_type=refresh_token

HTTP/1.1 400 Bad Request

{
  "error" : "invalid_request"
}

Answer 1

如果您收到 400 是因为您添加了无效参数或缺少参数。

编辑：

我相信从给定的数据来看，有一个额外的标题授权。仅当在 header 中传递 access_token 时，才会在 oauth2 中使用它，以进行经过身份验证的调用

Authorization : Bearer XXXXXXXXXXXXXXXX

刷新 access_token 时，无需在标头中提供相同内容。
