重定向url区分大小写。

在我的例子中，我添加了两个: http://localhost:5023/AuthCallback/IndexAsync http://localhost:5023/authcallback/indexasync

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...

我在谷歌登录时也遇到了同样的问题。

我已经在谷歌开发人员控制台的谷歌凭据面板中正确输入了我的回调 这是我的重定向网址:

https://www.example.com/signin-google

https://www.example.com/signin-google/

https://www.example.com/oauth2callback

https://www.example.com/oauth2callback/

一切似乎都很好，对吧?但它仍然没有工作，直到我添加了一个更神奇的Url，我添加了sign -google Url(这是默认的谷歌回调)没有www和问题解决。

考虑到这一点(取决于你的域名)，你可能需要或不需要同时添加www url

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,
}

以下是Error: redirect_uri_mismatch问题发生的原因:

重定向URL字段空白在您的谷歌项目。 重定向URL与您的网站不匹配 重要!它将只与工作域，如example.com, book.com等(不与本地主机或AWS LB URL工作)

建议使用域URL

在我的例子中，我的证书应用类型是“其他”。所以我无法在凭证页中找到授权重定向uri。它似乎出现在应用程序类型:“Web应用程序”。但是您可以单击Download JSON按钮来获取client_secret。json文件。

打开json文件，你可以找到这样的参数:"redirect_uri ":["urn:ietf:wg:oauth:2.0:oob"，"http://localhost"]。我选择使用http://localhost，它很适合我。
