在 Docker 中使用 React 和 Nginx 授权 Spotify

Question

我正在构建具有以下结构的 dockerized REST API 应用程序：

../
  web/
  nginx/
       dev.conf   
       Dockerfile-dev  
  client/
        build/
        conf/
        Dockerfile-dev
        node_modules/
        package_json
        public/
        src/
           App.jsx   
           components/ 
                     SpotifyRedirect.jsx                  
 spotify-client/ 
                Dockerfile-dev
                node_modules
                package-lock.json
                package.json
                authorization_code/
                                  app.js 

---

注意：在这个项目中，用户需要经过两个授权/认证过程：

1. 一个与我的应用程序，它生成一个原生的token（这个已经处理 已经）

2. 另一个Spotify（需要redirect URI，并为其API访问提供自己的token）

   2a) 所以，在localhost，在localhost/auth/register 或localhost/auth/login 提交之后，我会得到Spotify redirect URI (http://localhost:8888)，带我到这个页面：

2b) 然后，点击登录按钮，系统会要求我将我的应用与 Spotify 连接，如下所示：

最后一个OK 在那里我将获得许可并交给我一个token，我可以在我的React 客户端上保存甚至刷新它。

本项目的构建块摘自本教程：

using-spotifys-awesome-api-with-react

但是，我已经配置了一个Reactclient，除了这个授权过程之外，它还有其他用途。

以下是尝试集成这两个服务的相关代码：更通用的client 和spotify-client。

---

相关代码：

所以我的第一个尝试是为spotify-client 创建一个特定的服务，在client 服务下面，将其暴露给端口8888，如下所示：

docker-compose-dev.yml

  nginx:
    build:
      context: ./services/nginx
      dockerfile: Dockerfile-dev
    restart: always
    ports:
      - 80:80
    depends_on:
      - web
      - client
      - spotify-client

  client:
    build:
      context: ./services/client
      dockerfile: Dockerfile-dev
    volumes:
      - './services/client:/usr/src/app'
      - '/usr/src/app/node_modules'
    ports:
      - 3007:3000
    environment:
      - NODE_ENV=development
      - REACT_APP_WEB_SERVICE_URL=${REACT_APP_WEB_SERVICE_URL}
    depends_on:
      - web

  spotify-client: // NEW
    build:
      context: ./services/spotify-client
      dockerfile: Dockerfile-dev
    volumes:
      - './services/spotify-client:/usr/src/app'
      - '/usr/src/app/node_modules'
    ports:
      - 3000:8888
      - 8888:3000
    environment:
      - NODE_ENV=development
      - REACT_APP_WEB_SERVICE_URL=${REACT_APP_WEB_SERVICE_URL}
    depends_on:
      - web
      - client

然后，我将每个节点进程设置为自己的Dockerfile，如下所示：

客户端/Dockerfile-dev

# base image
FROM node:11.6.0-alpine

# set working directory
WORKDIR /usr/src/app

# add `/usr/src/app/node_modules/.bin` to $PATH
ENV PATH /usr/src/app/node_modules/.bin:$PATH

# install and cache app dependencies
COPY package.json /usr/src/app/package.json
RUN npm install --silent
RUN npm install react-scripts@2.1.2 -g --silent

# start app
CMD ["npm", "start"]

和：

spotify-client/Dockerfile-dev // 新

根据Spotify 网络文档的要求，运行不同的进程：

# base image
FROM node:11.6.0-alpine

# set working directory
WORKDIR /usr/src/app/authorization_code

# add `/usr/src/app/node_modules/.bin` to $PATH
ENV PATH /usr/src/app/node_modules/.bin:$PATH

# install and cache app dependencies
COPY package.json /usr/src/app/package.json
RUN npm install --silent
RUN npm install react-scripts@2.1.2 -g --silent

# start app <-- NOT npm start
CMD ["node", "app.js"] 

我的反向代理，我试过了：

nginx/dev.conf

server {

  listen 80;
  listen 8888; // NEW

  location / {
    proxy_pass        http://client:3000;
    proxy_redirect    default;
    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-Host $server_name;
  }


  location /auth {    // <-- app authorization, not Spotify's
    proxy_pass        http://web:5000;
    proxy_redirect    default;
    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-Host $server_name;
  }

在我的前端，我为我的重定向链接创建了一个component：

client/src/components/SpofityRedirect.jsx

import React, { Component } from 'react';

class SpotifyRedirect extends Component{
    render(){
        return (
            <div className='SpotifyRedirect'>
                <a href='http://localhost:8888'> Log in with Spotify </a>
            </div>
        );
    }
}

export default SpotifyRedirect;

这里我在“/”处显示这个重定向链接。

client/src/App.jsx

import SpotifyRedirect from './components/SpotifyRedirect';

 (...)
 <Switch
  <Route exact path='/' render={() => (
   <SpotifyRedirect/>
  )} />

 (...)
 </Switch>

最后，在构建之前，我运行：

$ export REACT_APP_WEB_SERVICE_URL=http://localhost

到目前为止，通过配置 aboce，当我点击 Log in with Soptify 时，我得到：

问题：

如何将上述配置与我的nginx reverse proxy 一起使用，以便：

1. 为位置 / 提供我的 Spotify's 重定向 uri http://localhost:8888 的链接
2. 使用 Spotify 授权应用程序
3. 授权完成后返回位置 '/'？

Answer 1

问题：8888端口没有容器监听，可以直接在8888端口发布spotify-client:8888（不用nginx）。更新docker-compose-dev.yml：

 spotify-client:
    ports:
      - 8888:8888

如果你真的需要 nginx，那么你将需要使用 nginx 配置 + 你还需要在 8888 端口上发布 nginx。 nginx/dev.conf 例子：

  server {
    listen 80;
    location / {
      proxy_pass        http://client:3000;
      proxy_redirect    default;
      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-Host $server_name;
    }
    location /auth {
      proxy_pass        http://web:5000;
      proxy_redirect    default;
      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-Host $server_name;
    }
  }

  # reverse proxy on the port 8888 for spotify-client
  server {
    listen  8888;
    location / {
      proxy_pass http://<spotify-client service/ip>:<port>/;
      proxy_redirect    default;
      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-Host $server_name;
    }
  }

docker-compose-dev.yml 和 nginx 发布的端口：

  nginx:
    ports:
      - 80:80
      - 8888:8888

一般情况下需要正确配置nginx:8888->spotify-client:port。

恕我直言：您根本不需要spotify-client 服务。只需在您的应用中使用implicit flow 即可获取 Spotify 令牌。它是 React/Angular（浏览器 JS 代码）更好的选择。请记住，此流程中不存在刷新令牌，因此您还需要实现静默刷新。

Answer 2

当您决定使用 nginx 时，您需要编辑配置并在端口 8888 上发布 nginx。
