在Nginx上托管静态angular2应用程序，并将HTTP请求代理到后端api [英] Hosting static angular2 app on nginx and proxying http requests to backend api

问题描述

如何获取angular2路由以工作并将HTTP请求代理到另一台计算机上的rest api?

我在Nginx服务器上有一个angular2 Web应用程序，该应用程序提供静态html文件.我在具有不同IP地址的另一台计算机上托管了一个单独的rest api.我已在nginx配置文件中将位置设置为/，以允许angular2路由正常工作.我还添加了一个位置/api/，我希望它可以拦截任何api请求并将它们代理到我的后端api.

I have an angular2 web application on an nginx server which serves the static html files. I have a separate rest api hosted on a different machine with a different IP address. I have set the location to / in my nginx config file to allow the angular2 routes to work correctly. I have also added a location /api/ which i hoped would intercept any api requests and proxy them to my backend api.

出于测试目的，我的nginx conf代理设置为 http://swapi.co .

My nginx conf with proxy set to http://swapi.co for test purposes.

events {
  worker_connections  4096;  ## Default: 1024
}

http {
  server {
    listen       80;
    server_name  localhost;

    root   /usr/share/nginx/html;
    index  index.html index.htm;
    include /etc/nginx/mime.types;

    location / {
         # If you want to enable html5Mode(true) in your angularjs app for pretty URL
         # then all request for your angularJS app will be through index.html
         try_files $uri /index.html;
    }

    # /api will server your proxied API that is running on same machine different port
    # or another machine. So you can protect your API endpoint not get hit by public directly
    location /api/ {
        proxy_pass http://swapi.co;
        proxy_http_version 1.1;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection 'upgrade';
        proxy_set_header Host $host;
        proxy_cache_bypass $http_upgrade;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    }

    location ~* .(jpg|jpeg|png|gif|ico|css|js)$ {
        expires 1d;
    }
  } 
}

我的angular2服务

My angular2 service

import { Injectable } from '@angular/core';
import { Http, Response } from '@angular/http';
import { Observable } from 'rxjs/Observable';

@Injectable()
export class Service {

  private url: string = '/api/people/';
  constructor (private http: Http) {}

  getPeople () {
    return this.http.get(this.url)
                  .map(res => res.json());
  }
}

任何帮助将不胜感激.

推荐答案

在我的开发环境中，将其正确地代理请求.添加到http块中，并将指向代理的值传递给上游api值

Got it to proxy requests correctly in my development environment. Added to the http block and pointed proxy pass to the upstream api value

upstream api {
  server 192.168.0.15:9998;
}

完成配置:

events {
  worker_connections  4096;  ## Default: 1024
}

http {

  # Change this depending on environment
  upstream api {
    server 192.168.0.1:9998;
  }

  server {
    listen       80;
    server_name  localhost;

    root   /usr/share/nginx/html;
    index  index.html index.htm;
    include /etc/nginx/mime.types;

    location / {
      # If you want to enable html5Mode(true) in your angularjs app for pretty URL
      # then all request for your angularJS app will be through index.html
      try_files $uri /index.html;
    }

    # /api will server your proxied API that is running on same machine different port
    # or another machine. So you can protect your API endpoint not get hit by public directly
    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_cache_bypass $http_upgrade;
      proxy_set_header X-Real-IP $remote_addr;
      proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    }

    #Static File Caching. All static files with the following extension will be cached for 1 day
    location ~* .(jpg|jpeg|png|gif|ico|css|js)$ {
      expires 1d;
    }
  }
}
