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。


当前回答

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,
}

其他回答

这个答案与Mike的答案和Jeff的答案相同,都在客户端设置redirect_uri为postmessage。我想添加更多关于服务器端的信息,以及适用于此配置的特殊情况。

技术堆栈

后端

Python 3.6 Django 1.11 Django REST Framework 3.9:服务器作为API,不渲染模板,在其他地方没有做太多。 Django REST Framework JWT 1.11 Django REST Social Auth < 2.1

前端

React: 16.8.3, create-react-app版本2.1.5 react-google-login: 5.0.2

“代码”流程(专门用于谷歌OAuth2)

总结:React—>请求社交认证“代码”—>请求jwt令牌,以获得您自己的后端服务器/数据库的“登录”状态。

Frontend (React) uses a "Google sign in button" with responseType="code" to get an authorization code. (it's not token, not access token!) The google sign in button is from react-google-login mentioned above. Click on the button will bring up a popup window for user to select account. After user select one and the window closes, you'll get the code from the button's callback function. Frontend send this to backend server's JWT endpoint. POST request, with { "provider": "google-oauth2", "code": "your retrieved code here", "redirect_uri": "postmessage" } For my Django server I use Django REST Framework JWT + Django REST Social Auth. Django receives the code from frontend, verify it with Google's service (done for you). Once verified, it'll send the JWT (the token) back to frontend. Frontend can now harvest the token and store it somewhere. All of REST_SOCIAL_OAUTH_ABSOLUTE_REDIRECT_URI, REST_SOCIAL_DOMAIN_FROM_ORIGIN and REST_SOCIAL_OAUTH_REDIRECT_URI in Django's settings.py are unnecessary. (They are constants used by Django REST Social Auth) In short, you don't have to setup anything related to redirect url in Django. The "redirect_uri": "postmessage" in React frontend suffice. This makes sense because the social auth work you have to do on your side is all Ajax-style POST request in frontend, not submitting any form whatsoever, so actually no redirection occur by default. That's why the redirect url becomes useless if you're using the code + JWT flow, and the server-side redirect url setting is not taking any effect. The Django REST Social Auth handles account creation. This means it'll check the google account email/last first name, and see if it match any account in database. If not, it'll create one for you, using the exact email & first last name. But, the username will be something like youremailprefix717e248c5b924d60 if your email is youremailprefix@example.com. It appends some random string to make a unique username. This is the default behavior, I believe you can customize it and feel free to dig into their documentation. The frontend stores that token and when it has to perform CRUD to the backend server, especially create/delete/update, if you attach the token in your Authorization header and send request to backend, Django backend will now recognize that as a login, i.e. authenticated user. Of course, if your token expire, you have to refresh it by making another request.

我的天啊,我花了6个多小时终于答对了!我想这是我第一次看到这种post - message的东西。任何使用Django + DRF + JWT + Social Auth + React组合的人都肯定会遇到这种情况。我真不敢相信,除了这里的答案,没有一篇文章提到这个。但是如果你正在使用Django + React堆栈,我真的希望这篇文章可以为你节省大量的时间。

1.您将看到类似这样的错误

2.然后单击请求详细信息

在此之后,您必须复制该url并将其添加到https://console.cloud.google.com/

访问https://console.cloud.google.com/

点击菜单-> API和服务->凭证

你会看到一个这样的仪表板,点击编辑OAuth客户端 现在在授权Javascript起源和授权重定向url 添加显示错误的url,称为redirect_uri_mismatch,即这里 http://algorithammer.herokuapp.com,所以我在这两个地方都加了 授权Javascript源和授权重定向url 点击保存,等待5分钟,然后尝试再次登录

在我的例子中,重置secret ('reset secret'-按钮)就成功了。

小心url末尾多余的/ http://localhost:8000和http://localhost:8000/不同

试着做这些检查:

控制台和应用程序中的Bundle ID。我更喜欢这样设置应用程序的Bundle ID: "org.peredovik.${PRODUCT_NAME:rfc1034identifier}" 检查你是否在信息选项卡添加了URL类型,只需在标识符和URL方案中输入你的Bundle ID,角色设置为编辑器 在控制台cloud.google.com“api & auth”->“同意屏幕”填写关于您的应用程序的表格。“产品名称”是必填字段。

享受:)
