【中文标题】在 React/Express 中使用 PassportJS 进行 Google OAuth 时出现 CORS 错误【英文标题】:Getting CORS error when using PassportJS for Google OAuth in React/Express 【发布时间】:2021-08-27 01:27:44 【问题描述】:尽管找了几个小时,但我还是找不到简单的 cors 错误的解决方案。我在浏览器中得到以下内容:
在 'https://accounts.google.com/o/oauth2/v2/auth?response_type=code&redirect_uri=http%3A%2F%2Flocalhost%3A3001%2Fapi%2Fauth%2Fauth%2Fgoogle%2Fcallback&scope= 访问 XMLHttpRequest profile%20email&client_id=******.apps.googleusercontent.com' (从 'http://localhost:3000/api/auth/auth/google' 重定向)来自 'http://localhost:3000'已被 CORS 策略阻止:请求的资源上不存在“Access-Control-Allow-Origin”标头。
出于安全原因,我刚刚为这篇文章替换了客户端 ID。 当我在 Postman/Thunder Client 中进行此调用时,它会返回 200 响应并且似乎工作正常
所以我尝试在 express app.use(cors());
中使用 cors NPM 包也尝试在 server.js app.all("/*", function (req, res, next) res.header("Access-Control-Allow-Origin", "*"); next(); );
中使用此功能我也尝试使用`
const proxy = require('http-proxy-middleware');
module.exports = function(app)
app.use(proxy("/api/auth/auth/google",
target: "https://localhost:3000/",
changeOrigin: true
));
我刚刚完成了我在 SO 上找到的书中的所有解决方案,但到目前为止似乎没有一个可行。任何帮助将不胜感激这是我的代码:

Homepage.js
import React from "react";
import API from "../components/utils/API";
export default function HomePage()
const handleLogin = () =>
API.login();
;
const testing = () =>
console.log("Hello world!");
API.testing();
;
return (
<div>
<h1>Let's login with Google</h1>
<button onClick=handleLogin>Login</button>
<button onClick=testing>Testing</button>

);
API.js
import axios from "axios";
export default
login: function ()
return axios.get("/api/auth/auth/google");
,
testing: function ()
return axios.get("/api/auth/test");
,
;
Server.js
const express = require("express");
const passport = require("passport");
const routes = require("./routes");
const app = express();
const PORT = process.env.PORT || 3001;
const cors = require("cors");
app.use(cors());
// Define middleware here
app.use(express.urlencoded( extended: true ));
app.use(express.json());
require("./config/passport");
app.use(passport.initialize());
// Add routes, both API and view
app.use(routes);
// Start the API server
app.listen(PORT, function ()
console.log(`???? ==> API Server now listening on PORT $PORT!`);
);
auth.js(认证路由)
const router = require("express").Router();
const passport = require("passport");
const cors = require("cors");
const CLIENT_HOME_PAGE_URL = "http://localhost:3000";
/Route is api/auth/test
router.get("/test", function (req, res)
res.send(console.log("Test to backend"));
);
//Route is api/auth/auth/google/callback
router.get(
"/auth/google/callback",
passport.authenticate("google",
successRedirect: CLIENT_HOME_PAGE_URL,
failureRedirect: "/",
session: false,
),
function (req, res)
var token = req.user.token;
res.redirect("http://localhost:3000?token=" + token);
);
//Route is api/auth/auth/google/
router.get(
"/auth/google",
passport.authenticate("google", scope: ["profile", "email"] )
);
module.exports = router;
Passport.js
var passport = require("passport");
var GoogleStrategy = require("passport-google-oauth").OAuth2Strategy;
passport.serializeUser(function (user, done)
done(null, user);
);
passport.deserializeUser(function (user, done)
done(null, user);
);
passport.use(
new GoogleStrategy(
clientID:
"*****",
clientSecret: "*****",
callbackURL: "http://localhost:3001/api/auth/auth/google/callback",
,
function (accessToken, refreshToken, profile, done)
var userData =
email: profile.emails[0].value,
name: profile.displayName,
token: accessToken,
;
done(null, userData);
)
);
我知道这篇文章有点长,如果有人有任何想法或解决方案会对我有很大帮助。
【问题讨论】:
【参考方案1】:我最近遇到了同样的问题。使用
window.location.href = "http://localhost:5000/api/auth/google"
而不是
axios.get("/api/auth/auth/google")
解决了问题。
认证成功后,如果您想将用户重定向到用户发出登录请求的原始网址,您可以这样做...
const currentUrl = window.location.href
const encodedParam = encodeURI(`?redirectUrl=$currentUrl`)
window.location.href = `http://localhost:5000/api/auth/google$encodedParam`
将重定向值存储在会话中
req.session.redirectPath = req.query.redirectUrl
身份验证后,在您的回调路由中使用它
