我有一个节点应用程序在Apache和Nginx作为反向代理的服务上运行。
在同一台服务器上,Node REST API也在运行。
JavaScript代码如下所示:
api.js
// Express
const express = require('express');
const bodyParser = require('body-parser');
const cors = require('cors');
// Express App
const app = express();
// Env
const PORT = process.env.PORT || 3000;
const NODE_ENV = process.env.NODE_ENV || 'development';
// Config
app.use(bodyParser.json());
app.use(bodyParser.urlencoded({ extended: true }));
app.use(cors());
// Routes
const users = require('./routes/users');
// Angular Http content type for POST etc defaults to text/plain at
app.use(bodyParser.text(), function ngHttpFix(req, res, next) {
try {
req.body = JSON.parse(req.body);
next();
} catch(e) {
next();
}
});
app.use('/api', users);
app.listen(PORT, function() {
console.log('Listen on http://localhost:' + PORT + ' in ' + NODE_ENV);
});
/routes/users.js
var models = require('../models');
var express = require('express');
var router = express.Router();
// get all users
router.get('/users', function(req, res) {
models.Beekeeper.findAll({}).then(function(users) {
res.json(users);
});
});
module.exports = router;
Nginx配置如下:
index index.html index.htm;
upstream api {
server 127.0.0.1:3000;
}
server {
listen 80;
server_name example.com;
return 301 https://$server_name$request_uri;
}
server {
listen 443;
root /var/www;
ssl on;
ssl_prefer_server_ciphers On;
ssl_protocols TLSv1.2;
ssl_session_cache shared:SSL:10m;
ssl_session_timeout 10m;
ssl_ciphers AES256+EECDH:AES256+EDH:!aNULL;
add_header Strict-Transport-Security "max-age=63072000; includeSubdomains; preload";
add_header X-Frame-Options DENY;
add_header X-Content-Type-Options nosniff;
ssl_dhparam /etc/nginx/ssl/dhparam.pem;
ssl_certificate /etc/letsencrypt/live/example.com/cert.pem;
ssl_certificate_key /etc/letsencrypt/live/example.com/privkey.pem;
server_name example.com;
location / {
proxy_pass http://127.0.0.1:8000;
proxy_http_version 1.1;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection "upgrade";
proxy_set_header Host $host;
proxy_set_header X-Real-Ip $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header X-Forwarded-Proto $scheme;
}
location /api {
proxy_pass http://api;
proxy_http_version 1.1;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection "upgrade";
proxy_set_header Host $host;
proxy_set_header X-Real-Ip $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header X-Forwarded-Proto $scheme;
rewrite ^/api/?(.*) /$1 break;
proxy_redirect off;
}
}
问题是如果我在我的开发服务器上进行API调用,例如localhost:3000 / api / users,它会按预期工作。
但是,如果我在我的生产服务器上进行API调用,例如https://example.com/api/users,我会无法获取/用户和 404 NOT FOUND ,分别
我认为我的Nginx配置有问题,但是,虽然我已经在Stackoverflow上阅读了很多关于类似问题的帖子,但我无法解决问题。
答案 0 :(得分:4)
请注意,您要求:
https://example.com/api/users
但错误说明了这一点:
无法获取 / users
因此,在传递给您的节点服务器之前,/api
前缀将从请求路径中删除。
这是由这一行完成的:
rewrite ^/api/?(.*) /$1 break;
解决方案:删除该行。
