在https://code.google.com/apis/console网站上，我已经注册了我的应用程序，设置生成的客户端ID:和客户端秘密到我的应用程序，并尝试登录谷歌。
不幸的是，我收到了错误信息:
Error: redirect_uri_mismatch
The redirect URI in the request: http://127.0.0.1:3000/auth/google_oauth2/callback did not match a registered redirect URI
scope=https://www.googleapis.com/auth/userinfo.profile https://www.googleapis.com/auth/userinfo.email
response_type=code
redirect_uri=http://127.0.0.1:3000/auth/google_oauth2/callback
access_type=offline
approval_prompt=force
client_id=generated_id
这条信息是什么意思，我该如何修复它?
我使用宝石omniauth-google-oauth2。
Let me complete @Bazyl's answer: in the message I received, they mentioned the URI
"http://localhost:8080/"
(which of course, seems an internal google configuration). I changed the authorized URI for that one,
"http://localhost:8080/" , and the message didn't appear anymore... And the video got uploaded... The APIS documentation is VERY lame... Every time I have something working with google apis, I simply feel "lucky", but there's a lack of good documentation about it.... :( Yes, I got it working, but I don't yet understand neither why it failed, nor why it worked... There was only ONE place to confirm the URI in the web, and it got copied in the client_secrets.json... I don't get if there's a THIRD place where one should write the same URI... I find nor only the documentation but also the GUI design of Google's api quite lame...
如果你正在使用passport js，你正在heroku中部署你的应用程序，你需要在passport策略中添加这个设置proxy: true
passport.use(new GoogleStrategy(
{
clientID: keys.googleClientID,
clientSecret: keys.googleClientSecret,
callbackURL: '/auth/google/callback',
proxy: true
})
或检查您的授权url
必须是https://yourwebsite/auth/google/callback
