Return 使用 Next-auth 时来自 API 的错误信息

Question

是否可以允许 API 的 return 错误并从客户端传递它们？

例如，如果用户的电子邮件或密码不正确，API 会 returning。在我们的移动应用程序上，这很好用。尽管在网站上，我们使用的是 Next-auth。使用文档中的凭据示例，将 return 值更改为对象会很棒。

import CredentialsProvider from "next-auth/providers/credentials"
providers: [
  CredentialsProvider({
    name: "Credentials",
 
    credentials: {
      username: { label: "Username", type: "text", placeholder: "jsmith" },
      password: {  label: "Password", type: "password" }
    },
    async authorize(credentials, req) {
      const user = { id: 1, name: "J Smith", email: "jsmith@example.com" }

      if (user) {
        // Any object returned will be saved in `user` property of the JWT
        return user
      } else {
        // Return an object that will pass error information through to the client-side.
        return { errors: user.errors, status: false }
      }
    }
  })
]

如果还有与此相关的 post，请告诉我，因为我无法在网上找到它。

是的，这应该允许您这样做，但在凭证中，当将值传递给下一个身份验证时，添加一个 redirect:false

您可以找到文档 here

因此您的登录方法将如下所示。

signIn('credentials', { redirect: false, username:'username', password: 'password' })

您的代码可以如下所示

import CredentialsProvider from "next-auth/providers/credentials"
providers: [
  CredentialsProvider({
    name: "Credentials",
 
    credentials: {
      username: { label: "Username", type: "text", placeholder: "jsmith" },
      password: {  label: "Password", type: "password" }
    },
    async authorize(credentials, req) {
      const user = { id: 1, name: "J Smith", email: "jsmith@example.com" }

      if (user) {
        // Any object returned will be saved in `user` property of the JWT
        return user
      } else {
        // Return an object that will pass error information through to the client-side.
        throw new Error( JSON.stringify({ errors: user.errors, status: false }))
      }
    }
  })
