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...

如果你使用这个教程:https://developers.google.com/identity/sign-in/web/server-side-flow，那么你应该使用“postmessage”。

在GO中，这解决了问题:

confg = &oauth2.Config{
        RedirectURL:  "postmessage",
        ClientID:   ...,
        ClientSecret: ...,
        Scopes:      ...,
        Endpoint:     google.Endpoint,
}

对于我的web应用程序，我纠正了我的错误

instead of : http://localhost:11472/authorize/
type :      http://localhost/authorize/

重要补充:我发现在跨客户端服务器认证流程中，当你从Web SDK接收到serverAuthCode时，你应该使用“postmessage”，当你从Android或iOS SDK接收到serverAuthCode时，将redirect_uri设置为空。

Rails用户(来自omniauth-google-oauth2文档):

修复redirect_uri在Rails中的协议不匹配 只需要根据Rails.env在OmniAuth中设置full_host。 #配置/初始化/ omniauth.rb OmniAuth.config。full_host = Rails.env.production?？ 'https://domain.com': 'http://localhost:3000'

记住:不要包括后面的"/"

在我的情况下，我必须检查客户端ID类型的web应用程序/已安装的应用程序。

已安装的应用程序:http://localhost[重定向uri] 在这种情况下，localhost就可以工作了

web应用程序:您需要有效的域名[重定向uri:]
