vue-element-admin+跨域代理+部署Nginx代理

一：开发环境跨域代理

# URL代理拦截

1.在 .env.development 文件内配置：

# 环境变量以 VUE_APP_ 为开头。如:VUE_APP_API

# 开发环境配置
ENV = 'development'

# 开发环境请求后端api
VUE_APP_BASE_API = '/dev-api'
VUE_APP_OAUTH_API = '/oauth-api'

--------------------------------------------------------

2.在 vue.config.js 内配置：

devServer: {
    host: '0.0.0.0',
    port: port,
    open: true,
    proxy: {
      // detail: https://cli.vuejs.org/config/#devserver-proxy
      [process.env.VUE_APP_BASE_API]: {
        target: `http://localhost:9527`, // localhost
        changeOrigin: true,
        pathRewrite: {
          ['^' + process.env.VUE_APP_BASE_API]: ''
        }
      },
      [process.env.VUE_APP_OAUTH_API]: {
        target: `http://localhost:9528`, // 多跨域配置
        changeOrigin: true,
        pathRewrite: {
          ['^' + process.env.VUE_APP_OAUTH_API]: ''
        }
      }
    },
    disableHostCheck: true
  }


--------------------------------------------------------

3.在对应的api内引入使用，例子

const OAUTH_URL = process.env.VUE_APP_OAUTH_API

export function getCode(query) {
  return request({
    url: OAUTH_URL + '/oauth/authorize',
    method: 'get',
    params: query
  })
}

 

二：生产环境Nginx跨域代理

在 .env.production 内配置：

# 生产环境配置
ENV = 'production'

# 生产环境
VUE_APP_BASE_API = '/md-prod-api'
VUE_APP_OAUTH_API = '/md-oauth-api'

-----------------------------------------

在 nginx.conf 内配置：


#user  nobody;
worker_processes  1;

#error_log  logs/error.log;
#error_log  logs/error.log  notice;
#error_log  logs/error.log  info;

#pid        logs/nginx.pid;


events {
    worker_connections  1024;
}


http {
    include       mime.types;
    default_type  application/octet-stream;

    #log_format  main  '$remote_addr - $remote_user [$time_local] "$request" '
    #                  '$status $body_bytes_sent "$http_referer" '
    #                  '"$http_user_agent" "$http_x_forwarded_for"';

    #access_log  logs/access.log  main;

    sendfile        on;
    #tcp_nopush     on;

    #keepalive_timeout  0;
    keepalive_timeout  65;

    #gzip  on;

    server {
        listen       80;
        server_name  localhost;

        #charset koi8-r;

        #access_log  logs/host.access.log  main;

        
		# 项目根路径
		location / {
            root   /vueui/dist;
            // 说明：如果vue项目的router是 mode: 'history'，那么加下面一行。
            //注意打包时,publicPath: process.env.NODE_ENV === 'production' ? '/' : '/', 是否要加 ‘./’，要根据root的地址而定
            try_files $uri $uri/ /index.html;
            
            index  index.html index.htm;
        }
		
		# 配置代理转发（/md-prod-api 是.env.production 内定义的）
		location /md-prod-api/{
			proxy_set_header Host $http_host;
			proxy_set_header X-Real-IP $remote_addr;
			proxy_set_header REMOTE-HOST $remote_addr;
			proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
			proxy_pass http://localhost:9596/md/; // 后端接口
		}

        }

        # proxy the PHP scripts to Apache listening on 127.0.0.1:80

        #    deny  all;

    }


    # 需要Nginx监听多个端口，就多复制一份server{}
