aws-amplify/ui-reac，可以在登录后重定向

Question

你好，我正在尝试使用AWS-amplify和react-dom登录后重定向和更改路径

我需要在用户登录后将它们重定向到localhost/main main，因为它在localhost/中

如果任何人有一个想法可以帮助我，感谢我的代码：

import React from "react";
import "./App.css";
import { BrowserRouter as Router, Switch, Route } from "react-router-dom";
import Amplify from "aws-amplify";
import {
  AmplifyAuthenticator,
  AmplifySignUp,
} from "@aws-amplify/ui-react";
import { AuthState, onAuthUIStateChange } from "@aws-amplify/ui-components";
import awsconfig from "./aws-exports";
import Main from "./main";

Amplify.configure(awsconfig);

const AuthStateApp = () => {
  const [authState, setAuthState] = React.useState();
  const [user, setUser] = React.useState();

  React.useEffect(() => {
    return onAuthUIStateChange((nextAuthState, authData) => {
      setAuthState(nextAuthState);
      setUser(authData);
    });
  }, []);

  return authState === AuthState.SignedIn && user ? (
    <Router>
      <Switch>
        <Route path="/main">
          <Main />
        </Route>
      </Switch>
    </Router>
  ) : (
    <AmplifyAuthenticator>
      <AmplifySignUp
        slot="sign-up"
        formFields={[
          { type: "username" },
          { type: "password" },
          { type: "email" },
        ]}
      />
    </AmplifyAuthenticator>
  );
};

export default AuthStateApp;

Answer 1

在搜索这个问题后，解决方案是使用AUTH.signIn()和Auth.signUp()设计自己的登录和注册，然后可以重定向。

Answer 2

我使用的是angular，但我认为它可能类似

  onAuthUIStateChange((authState, authData) => {
            console.log('LoginPage', authState, authData);
            if (this.authState == AuthState.SignedIn) {
                this.router.navigate(['']);
            }
        });

我通常这样做：

authentication.

• At

• 使用<AwsAuthenticator>包装<router>，您将使用该组件检查并要求使用typescript(如果不使用typescript，则为js )，您将执行以下操作：<AwsAuthenticator> AwsAuthenticator.tsx

// @ts-ignore
import {Authenticator} from 'aws-amplify-react-native';
import React, {ReactNode, useState} from 'react';
import {signUpConfig} from '@app/components/Authentication/SignUpForm.config';

interface AwsAuthenticatorProps {
  children: ReactNode;
}

export const AwsAuthenticator = ({children}: AwsAuthenticatorProps) => {
  const [loggedIn, setLoggedIn] = useState<boolean>(false);

  // possible states: signIn | signedIn | signedOut
  const handleAuthStateChange = (authState: string) =>
    authState === 'signedIn' ? setLoggedIn(true) : setLoggedIn(false);

  return loggedIn ? (
    <>{children}</>
  ) : (
    <Authenticator
      usernameAttributes="email"
      signUpConfig={signUpConfig}
      onStateChange={handleAuthStateChange}
    />
  );
};
