Angular-CLI 代理在 docker 中不起作用 [英] Angular-CLI proxy not working inside docker

问题描述

我有一个 docker-compose 文件，其中包含我项目所需的一切.

I have a docker-compose file with everything I need for my project.

这个docker-compose有一个nginx服务器，mysql，phpmyadmin和php.在它的顶部，我最近添加了一个有角度的容器.如果我转到 localhost:4200，我在 angular 应用程序上，如果我转到 localhost:80，我在 Laravel 后端，一切正常.

This docker-compose has a nginx server, mysql, phpmyadmin and php. At the top of it, I added recently an angular container. Everything is working fine if I go to localhost:4200, I'm on the angular app, and if I go to localhost:80, I'm on the Laravel backend.

现在我需要向我的后端 API 发出一个简单的经典请求.我为 angular 设置了一个代理，如下所示:

Now I need to make a simple classical request to my backend API. I set up a proxy for angular looking like this :

{
   "/api/*": {
      "target":"http://localhost:80",
      "secure":false,
      "changeOrigin":true,
      "pathRewrite": {"^/api" : ""},
      "logLevel":"debug"
   }
}

这是我根据这个主题复制的配置.但是当我尝试拨打电话时，Chrome 说 http://localhost:4200/api/test 不存在(错误 404)，这是正常的.另一方面，角度服务器说
HPM] 尝试将请求/test 从 localhost:4200 代理到 http://localhost:80 (ECONNREFUSED) (https://nodejs.org/api/errors.html#errors_common_system_errors) 时出错

This is the config I copied based on this topic. But when I try to make the call, Chrome is saying that http://localhost:4200/api/test isn't existing (error 404) which is normal. On the other hand, the angular server says
HPM] Error occurred while trying to proxy request /test from localhost:4200 to http://localhost:80 (ECONNREFUSED) (https://nodejs.org/api/errors.html#errors_common_system_errors)

我猜它来自 docker，但我不知道如何解决这个问题.

I'm guessing it comes from docker but I can't figure out how to resolve this.

version: '2'

services:
  web_server:
    restart: always
    image: nginx:latest
    ports:
      - "80:80"
    volumes:
      - /projects/laravel/:/var/www/                                               
      - /docker/sites-enabled-nginx:/etc/nginx/sites-enabled/     
      - /docker/nginx.conf:/etc/nginx/nginx.conf
    links:
      - php:php

  php:
    restart: always
    build: /docker/php/
    container_name: "php"
    volumes:
      - /projects/laravel/:/var/www/       
      - db:db

  db:
    restart: always
    image: mysql
    volumes:
      - /Users/Irindul/mysql:/var/lib/mysql     
    ports:
      - "3306:3306"                                   
    container_name: "mysql"
    environment:
      - MYSQL_DATABASE=homestead
      - MYSQL_USER=homestead
      - MYSQL_PASSWORD=secret
      - MYSQL_ROOT_PASSWORD=root

  myadmin:
    restart: always
    image: phpmyadmin/phpmyadmin
    links:
      - db:db
    ports:
      - "8080:80"                                     



  angular:
    restart: always
    build: /docker/angular
    container_name: angular
    volumes:
      - /projects/angular/package.json:/usr/src/app/package.json
      - /projects/angular:/usr/src/app/
    ports:
      - "4200:4200"

这里是 PHP 和 Angular 的 Dockerfile:

And here are the Dockerfiles for PHP and Angular :

PHP:

FROM php:7-fpm
RUN docker-php-ext-install pdo pdo_mysql
WORKDIR /var/www

角度:

#Latest Node
FROM node

#Creating working folder
RUN mkdir -p /usr/src/app

#Update pwd
WORKDIR /usr/src/app

#Run npm
RUN npm install
EXPOSE 4200
CMD ["npm", "start"]

推荐答案

我通过从 docker 中删除 Angular 并使用简单的 npm start 手动运行它来解决这个问题.

I fixed the problem by removing Angular from the docker and running it manually with a simple npm start.
