【问题描述】：

尝试使用 Django rest + allauth + 从 Nuxt App 进行身份验证 dj-rest-auth

第一个错误

allauth.socialaccount.models.SocialApp.DoesNotExist：SocialApp 匹配查询不存在。

通过将 SITE_ID = 1 更改为 2 解决了这个问题

我第二次收到此错误

【问题讨论】：

错误解决了吗？我正在使用 dj-rest-auth（rest-auth 的分支）并尝试使用 Google 登录，在成功调用 Google 后，我得到了代码并将其发送到我的视图，但出现了这个错误。
不，它无法解决，所以我直接尝试使用 nuxt auth 包使用 google 进行身份验证。

标签： django django-rest-framework nuxt.js django-allauth django-rest-framework-simplejwt

【解决方案1】：

在 Django 视图中设置重定向 URL 以匹配在 OAuth 客户端 (Google) 中配置的重定向 URI：

class GoogleLogin(SocialLoginView):
    authentication_classes = []
    adapter_class = GoogleOAuth2Adapter
    callback_url = "http://localhost:3000/login" # <--- make sure this line is correct!
    client_class = OAuth2Client

如果没有提供任何代码，这将很难回答，但我看到您在 Medium tutorial on this topic 上的评论，我遇到了同样的问题。示例代码将/login 保留在 URL 之外。
