具有静态角应用程序的Express Api服务器在生产服务器`/ api`端点上返回404？

Question

我一直在使用expressjs和api服务器开发我的应用程序，Angular 6 as和api服务器在同一项目结构上像这样

所以这是我的index.js

void foo(int x = 7);

foo(5); // x = 5
foo(); // x = 7

这是我的const express = require('express'); const mongoose = require('mongoose'); const cookieSession = require('cookie-session'); const passport = require('passport'); const bodyParser = require('body-parser'); const keys = require('./config/keys'); require('./models/User'); mongoose.connect(keys.mongoURI); const app = express(); app.use(bodyParser({limit: '50mb'})); app.use(bodyParser.json()); app.use( cookieSession({ maxAge: 30 * 24 * 60 * 60 * 1000, keys: [keys.cookieKey] }) ); require('./routes/registerRoutes')(app); if (process.env.NODE_ENV === 'production') { // Express wil serve up production assets // like main.js, main.css app.use(express.static('client/dist')); // Express will serve up the index.hml file // if does not recognize the route const path = require('path'); app.get('*', (req, res) => { res.sendFile(path.resolve(__dirname, 'client', 'dist', 'index.html')); }) } const PORT = process.env.PORT || 5000; app.listen(PORT);

registerRoutes.js

它在localhost服务器上工作正常，但当我尝试使用const mongoose = require('mongoose'); const User = mongoose.model('users'); module.exports = (app) => { app.get('/api/competitors', async (req, res) => { const users = await User.find().sort({ created: 'desc' }); res.send({ users }); }); app.post('/api/register', async (req, res) => { const userObject = req.body; const user = new User({ firstName: userObject.firstName, lastName: userObject.lastName, nickName: userObject.nickName, }); try { const newUser = await user.save(); res.send(newUser); } catch (err) { res.status(422).send(err); } }); }; 作为反向代理部署到生产服务器时，这样做。

nginx

在静态网站上工作正常。 但是当我试着打电话时

server {
    listen 80;

    # server_name drtobias.com;

    location / {
        root project_name/client/dist;
        # index index.html;
        try_files $uri $uri/ @express; # instead of 404, proxy back to express using a named location $
        expires max;
        access_log off;
        # source: https://stackoverflow.com/a/15467555/8436941
    }

    location @express {
        proxy_set_header X-Real-IP  $remote_addr;
        proxy_set_header Host $host;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_pass http://myserver_ip_address:5000;
    }
}

我得到了Post '/api/register' 这样的错误。

那么如何解决这个问题并使网站正确响应api调用？
