我正在按照本教程使用 Flask OauthLib,尝试制作一个基本的 OAuth2 客户端以与 Foursquare.com 一起使用:https ://flask-oauthlib.readthedocs.org/en/latest/client.html#oauth2-client
在我授予使用该应用程序的权限后,我被重定向到包含以下文本的页面:
{
"meta": {
"code": 400,
"errorDetail": "Missing access credentials. See https://developer.foursquare.com/docs/oauth.html for details.",
"errorType": "invalid_auth"
},
"response": {}
}
怎么了?我该如何解决?谢谢。
