谷歌登录

//Npm
npm install @react-oauth/google@latest
//Yarn
yarn add @react-oauth/google@latest

在首页中引入 GoogleOAuthProvider，并写上google后台的clientId

/*index.js*/

import React from 'react';
import ReactDOM from 'react-dom';
import { GoogleOAuthProvider } from '@react-oauth/google';
import App from './App';

ReactDOM.render(
    <GoogleOAuthProvider clientId="386932037035-k8v833noqjk7m4***********.apps.googleusercontent.com">
        <React.StrictMode>
            <App />
        </React.StrictMode>
    </GoogleOAuthProvider>,
    document.getElementById('root')
);


组件页面中

/*App.js*/

import React from 'react';
import { GoogleLogin } from '@react-oauth/google';

function App() {
    const responseMessage = (response) => {
        console.log(response);
    };
    const errorMessage = (error) => {
        console.log(error);
    };
    return (
        <div>
            <h2>React Google Login</h2>
            <br />
            <br />
            <GoogleLogin onSuccess={responseMessage} onError={errorMessage} />
        </div>
    )
}
export default App;

也可以更改谷歌登录样式

/*App.js*/

import React, { useState, useEffect } from 'react';
import { googleLogout, useGoogleLogin } from '@react-oauth/google';
import axios from 'axios';

function App() {
    const [ user, setUser ] = useState([]);
    const [ profile, setProfile ] = useState([]);

    const login = useGoogleLogin({
        onSuccess: (codeResponse) => setUser(codeResponse),
        onError: (error) => console.log('Login Failed:', error)
    });

    useEffect(
        () => {
            if (user) {
                axios
                    .get(`https://www.googleapis.com/oauth2/v1/userinfo?access_token=${user.access_token}`, {
                        headers: {
                            Authorization: `Bearer ${user.access_token}`,
                            Accept: 'application/json'
                        }
                    })
                    .then((res) => {
                        setProfile(res.data);
                    })
                    .catch((err) => console.log(err));
            }
        },
        [ user ]
    );

    // log out function to log the user out of google and set the profile array to null
    const logOut = () => {
        googleLogout();
        setProfile(null);
    };

    return (
        <div>
            <h2>React Google Login</h2>
            <br />
            <br />
            {profile ? (
                <div>
                    <img src={profile.picture} alt="user image" />
                    <h3>User Logged in</h3>
                    <p>Name: {profile.name}</p>
                    <p>Email Address: {profile.email}</p>
                    <br />
                    <br />
                    <button onClick={logOut}>Log out</button>
                </div>
            ) : (
                <button onClick={login}>Sign in with Google 🚀 </button>
            )}
        </div>
    );
}
export default App;
