NGINX:使用域/路径在同一服务器上的多个节点js应用程序 [英] NGINX : multiple node js applications on same server using domain/path

问题描述

问题

如果我有一些节点js应用程序，并且要将其发布为mydomain.com/app1、mydomain.com/app2等，则必须将 app.get'/'更改为 app.get('/app1'，在某些情况下还包括css，js和图片路径.

If I have some node js apps and if I want publish it as mydomain.com/app1, mydomain.com/app2, etc I have to change the app.get '/' to app.get('/app1' and also in some cases css,js and images paths.

问题

要分配域/路径时，是否应该始终修改应用程序?

Should you always modify the application when you want to assign a domain/path?

有什么方法可以使应用程序独立吗?

Is there any way to make the application independent?

是nodejs还是nginx配置?

Is a nodejs or nginx configuration?

这是一个示例的节点js应用程序:

https://github.com/jrichardsz/sensitive_web1.1 /blob/master/server.js

这是我的 mydomain.com 节点js应用程序的Nginx配置(有效！)

This is my nginx configuration for my node js app for mydomain.com (works!)

server {
  listen 80;
  server_name mydomain.com;

  location / {
    proxy_pass http://localhost:8080/;
  }
}

节点应用程序:

app.get('/', function(req, res) {
    // ejs render automatically looks in the views folder
    res.render('index');
});

这是我对同一节点js应用程序的nginx配置，但 mydomain.com/app1 (有效！)

This is my nginx configuration for the same node js app but mydomain.com/app1 (works!)

server {
  listen 80;
  server_name mydomain.com;

  location /app1/ { 
    proxy_pass http://localhost:8080/app1/; 
  }
}

这是Node js应用程序中的修复程序

And this is the fix in node js app

app.get('/app1', function(req, res) {
    // ejs render automatically looks in the views folder
    res.render('index');
});

我尝试过:

https://github.com/expressjs/express-namespace

http://expressjs.com/en/4x/api.html

但是在两种情况下，我都需要更改我的node js应用.

But in both cases, I need change my node js app.

谢谢.

推荐答案

要分配域/路径时，是否应该始终修改应用程序?

Should you always modify the application when you want to assign a domain/path?

不，您根本不需要修改应用程序.

No, you shouldn't have to modify the application at all.

以这种方式使用proxy_pass时，需要用正则表达式重写URL.尝试这样的事情:

When you use proxy_pass in this manner, you need to rewrite the URL with regex. Try something like this:

  location ~ ^/app1/(.*)$ { 
    proxy_pass http://localhost:8080/$1$is_args$args; 
  }
