自定义登录页面在下次身份验证中无法正确重定向

Question

api/[...nextauth].js

export default NextAuth({
providers: [
    Providers.Credentials({
    name: 'Credentials',
    credentials: {
        email: { label: 'E-mail', type: 'text', placeholder: 'me@gmail.com' },
        password: { label: 'Password', type: 'password', placeholder: 'my password' },
    },
    async authorize(credentials, req) {
        return { email: 'x', password: 'y'}
    },
    }),
]
});

页面/auth/signin.tsx

export default function SignIn() {
const [password, setPassword] = useState(null)
const [email, setEmail] = useState(null)

const onSubmit = () => {
    signIn("Credentials", { email, password })
}

return (
    <div>
    <label>
        Email
        <input name="email" type="text" onChange={e => setEmail(e.target.value)} />
    </label>
    <label>
        Password
        <input name="password" type="password"  onChange={e => setPassword(e.target.value)} />
    </label>
    <button type="submit" onClick={onSubmit}>Sign in!</button>
    </div>
)
}

onSubmit 重定向到默认登录页面/api/auth/signin?callbackUrl=http%3A%2F%2Flocalhost%3A3000%2Fauth%2Fsignin，而不是正确登录并重定向到/。如何解决这个问题？

我在使用标签的自定义签名表单中也遇到了同样的问题form（https://next-auth.js.org/configuration/pages#credentials-sign-in）

我找到了解决方案，但我认为文档具有误导性。

我所做的是将 id 属性添加到我的 [...nextauth].js 提供程序：

import Credentials from 'next-auth/providers/credentials';

export default NextAuth({
  providers: [
    Credentials({
      id: 'credentials',
      name: 'Credentials',
      credentials: {
        username: { label: 'Adresse email', type: 'email' },
        password: { label: 'Mot de passe', type: 'password' },
      },
      async authorize(credentials, req) {
        console.log(credentials);
        const user = { id: 1, name: 'Jean Dupont', email: 'jean.dupont@yopmail.com' };

        if (user.id === 1) {
        // Any object returned will be saved in `user` property of the JWT
          return user;
        }
        // If you return null or false then the credentials will be rejected
        return null;
        // You can also Reject this callback with an Error or with a URL:
        // throw new Error('error message') // Redirect to error page
        // throw '/path/to/redirect'        // Redirect to a URL
      },
    }),
  ],
  pages: {
    signIn: '/auth/login',
  },
});

然后，我像以前一样调用 SignIn 函数，将 name 参数替换为 id 并按照最初的期望路由到“/”

// ...
await signIn('credentials', { email, password, callbackUrl: `${window.location.origin}/` });
// ...

问题是文档没有提到提供程序中 id 属性的使用。仅在多个提供程序示例代码中提到： https: //next-auth.js.org/providers/credentials#multiple-providers，并且凭证提供程序配置页面中也没有任何内容：https://next-auth。 js.org/configuration/providers/credentials-provider。
