我正在使用以下堆栈：
当我进行表单提交时，我收到错误无法POST但是当我使用POSTMAN或curl XPOST提交到SAME网址时，我得到了结果。这是我的server.js代码：
'use strict';
const PORT = process.env.PORT || 3001;
const express = require('express');
const app = express();
const path = require('path');
const passport = require('passport')
const initPassport = require('./passport/init');
const session = require('express-session')
const mongoose = require('mongoose');
const bodyParser = require('body-parser');
const cookieParser = require('cookie-parser')
const configDB = require('./config/database.js');
const MongoStore = require('connect-mongo')(session);
var flash = require('connect-flash');
//Connect to mongo
mongoose.connect(configDB.url, {
useMongoClient: true
}).then(() => console.log('connection with database succeeded'))
.catch(err => console.error(err));
// Initialize Passport
initPassport(passport);
// Serve static assets
app.use(express.static(path.resolve(__dirname, '..', 'build')));
//use cookie parser to store data
app.use(cookieParser());
app.use(session({
secret: 'mysecret',
store : new MongoStore ({
db : mongoose.connection.db,
host : '127.0.0.1',
port : '27017',
url : configDB.url
}),
maxAge : 2 * 60 * 60 * 1000,
resave: false,
saveUninitialized: false
})); // session secret
app.use(bodyParser.urlencoded({ extended: false }));
app.use(passport.initialize());
app.use(passport.session()); // persistent login sessions
app.use(flash()); // use connect-flash for flash messages stored in session
app.post('/signup', passport.authenticate('signup', {
successRedirect: '/',
failureRedirect: '/signup'
}));
app.listen(PORT, () => {
console.log(`App listening on port ${PORT}!`);
});

更新
问题似乎是由于代理的存在。如果我直接调用在不同端口上运行的nodejs后端API（通过允许CORS）并删除代理，则表单提交有效。如果我插入代理，并使表单指向weback dev服务器，则表单提交不会调用我的nodeJS API。但是，代理与curl和POSTMAN一起使用。很奇怪curl如何工作和表单提交没有。这里的任何指示都会有所帮助。
