Question

我想跟随史蒂芬格里德在Udemy的全栈反应课程。

我浪费了几天试图解决阻止我遵循他的教程的代理错误 - 它似乎没有任何Q＆amp; A支持。

在我的authRoutes.js文件中，我有：

const passport = require（'passport'）;

module.exports = (app) => {
  app.get(
    '/auth/google',
    passport.authenticate('google', {
      scope: ['profile', 'email']
    })
  );

  app.get(
    '/auth/google/callback',
    passport.authenticate('google'),
    (req, res) => {
      res.redirect('/dashboard')
    }
  );

  app.get('/api/logout', (req, res) => {
    req.logout();
    res.redirect('/');
  });

  app.get('/api/current_user', (req, res) => {
    res.send(req.user);
  });

};

在我的passport.js文件中，我有：

const passport = require('passport');
const GoogleStrategy = require('passport-google-oauth20').Strategy;
const OrcidStrategy = require('passport-orcid');
const LinkedinStrategy = require('passport-linkedin');
const keys = require('../config/keys');
const mongoose = require('mongoose');

const User = mongoose.model('users');

passport.serializeUser((user, done) => {
  done(null, user.id);
});

passport.deserializeUser((id, done) => {
  User.findById(id)
  .then(user => {
    done(null, user);
  });
});


passport.use(
  new GoogleStrategy({
    clientID: keys.googleClientID,
    clientSecret: keys.googleClientSecret,
    callbackURL: '/auth/google/callback',
    proxy: true
  },
  async (accessToken, refreshToken, profile, done) => {
    const existingUser = await User.findOne({ googleId: profile.id })

    if(existingUser){
      //User already exists
      return done(null, existingUser);
    }
    // create a new user
    const user = await new User({ googleId: profile.id}).save()
    done(null, user);

Stephen建议在客户端的package.json中使用代理脚本，将本地主机3000重定向到本地主机5000，如下所示：

"proxy": {
    "/auth/google": {
      "target": "http://localhost:5000"
    },
    "api/*": {
      "target": "http://localhost:5000"
    }
  },

当我尝试在开发中运行它时，我收到以下错误。

代理错误：无法代理请求/ auth / google / callback？code = 4 / xxx from localhost：3000 to http://localhost:5000（ECONNRESET）。

日志提供了以下信息：

When I try to push to heroku and test it in production, I get a response saying cannot get /".

有谁知道如何使用Stephen的课程方法来设置基本的mern堆栈应用程序？

有没有人在克服这些具体问题上取得任何成功？这是浪费时间发布到斯蒂芬的Q＆amp; A - 他没有回答问题。

Answer 1

此问题是由将版本从1.1.15迁移到2.0.1引起的。要解决此问题，您现在应该在package.json文件中删除代理设置，并改为执行以下操作：

在您的客户文件夹中：

$ npm install http-proxy-middleware --save
$ # or
$ yarn add http-proxy-middleware

像这样将条目放入src / setupProxy.js：

const proxy = require('http-proxy-middleware')

module.exports = function(app) {
  app.use(proxy('/api', { target: 'http://localhost:5000/' }))
  app.use(proxy('/*.svg', { target: 'http://localhost:5000/' }))
}

注意：您不必导入setupProxy.js。

Answer 2

const { createProxyMiddleware }= require('http-proxy-middleware');

module.exports = function(app) {
    app.use( createProxyMiddleware('/auth/google', { target: 'http://localhost:5000' }));
    app.use( createProxyMiddleware('/api/**', { target: 'http://localhost:5000' }));
};
