是的，这应该允许您这样做，尽管在凭证中，当将值传递给下一个auth时，添加redirect:false
您可以在此处找到文档
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 }))
      }
    }
  })

我通过在authorize函数中使用带有catch语句的promise来返回正确的错误信息：

export const authOptions: NextAuthOptions = {
  session: {
    strategy: "jwt",
  },
  secret: process.env.NEXTAUTH_SECRET,
  providers: [
    CredentialsProvider({
      name: "credentials",
      credentials: {
        email: {
          label: "Email",
          type: "email",
          placeholder: "example@example.com",
        },
        password: { label: "Password", type: "password" },
      },
      async authorize(credentials: any) {
        // console.log(credentials);
        const { user, jwt } = await axios
          .post(`http://localhost:1337/api/auth/local`, {
            identifier: credentials.email,
            password: credentials.password,
          })
          .then(({ data }) => {
            return data;
          })
          .catch((error) => {
            throw new Error(JSON.stringify(error.response.data));
          });

        return { jwt, ...user };
      },
    }),
  ],
};
const handler = NextAuth(authOptions);
export { handler as GET, handler as POST };

next-auth错误的类型是string，因此您需要将其字符串化为JSON，然后从客户端将其转换回对象。
