节点js没有访问控制允许来自其他问题的原始答案也不起作用
我有节点js服务器，你可以在这里查看 -
在index.js我有以下内容
const express = require('express')
const cors = require('cors')
const bodyParser = require('body-parser')
const passport = require('passport')
const localSignupStrategy = require('./passport/local-signup')
const localLoginStrategy = require('./passport/local-login')
const authRoutes = require('./routes/auth')
const postRoutes = require('./routes/post')
const commentRoutes = require('./routes/comment')
const app = express()
const port = 5000
const envConfig = require('./config/environment')
require('./config/database')(envConfig)
app.use(function (req, res, next) {
// Website you wish to allow to connect
res.setHeader('Access-Control-Allow-Origin', '');
// Request methods you wish to allow
res.setHeader('Access-Control-Allow-Methods', 'GET, POST, OPTIONS, PUT, PATCH, DELETE');
// Request headers you wish to allow
res.setHeader('Access-Control-Allow-Headers', 'X-Requested-With,content-type');
// Set to true if you need the website to include cookies in the requests sent
// to the API (e.g. in case you use sessions)
res.setHeader('Access-Control-Allow-Credentials', true);
// Pass to next layer of middleware
next();
});
app.use(bodyParser.urlencoded({ extended: false }))
app.use(bodyParser.json())
app.use(passport.initialize())
//app.use(cors())
passport.use('local-signup', localSignupStrategy)
passport.use('local-login', localLoginStrategy)
// routes
app.use('/auth', authRoutes)
app.use('/post', postRoutes)
app.use('/comment', commentRoutes)
app.listen(port, () => {
console.log(`Server running on port ${port}...`)
})
加入app.use()的Access-Control-Allow-Origin是从这里复制的 - No 'Access-Control-Allow-Origin' - Node / Apache Port Issue
我也尝试了其他问题，但它不起作用。
我试过了
app.use(cors())
app.use(cors({origin:"front-end-url"}))
app.use(cors({origin:null}))
app.use(cors({origin:"*"}))
如其他答案中所述，但没有任何作用。
这是我得到的错误 -
对预检请求的响应未通过访问控制检查：请求的资源上不存在“Access-Control-Allow-Origin”标头。
如果你想在这里重新创建它是前端Login并填写表格并按下控制台上的“注册”你会看到错误。

在每个网址的选项中添加cors。
var cors = require('cors');
router.options('/post', cors());
