vue-element-admin 打包gzip压缩优化vue项目大小并部署到Nginx，报404，接口访问不了

在根目录的vue.config.js的！== 'development’这里添加上图所示的配置。config.when(process.env.NODE_ENV !== 'development',config => {config.plugin('ScriptExtHtmlWebpackPlugin').after('html').use('script-e.

// use administrator privileges to execute the command line.
// For example, Mac: sudo npm run
// You can change the port by the following method:
// port = 9527 npm run dev OR npm run dev --port = 9527
const port = process.env.port || process.env.npm_config_port || 9888 // dev port

// All configuration item explanations can be find in https://cli.vuejs.org/config/

  }
}

项目使用Nginx部署，所以也要配置一下Nginx
在Nginx的conf目录下修改nginx.conf文件
在这里插入图片描述
在http中增加如上图代码

    gzip on;
	gzip_static on;
	gzip_min_length 1k;
	gzip_buffers 4 32k;
	gzip_http_version 1.1;
	gzip_comp_level 2;
	gzip_types text/plain application/x-javascript text/css application/xml;
	gzip_vary on;
	gzip_disable "MSIE [1-6].";

此外需要部署到服务器给外网访问，可能也要配置跨域
在这里插入图片描述

			error_page 405 =200 http://$host$request_uri;
			
			add_header Access-Control-Allow-Origin *;
			add_header Access-Control-Allow-Methods 'GET, POST, OPTIONS';
			add_header Access-Control-Allow-Headers 'DNT,X-Mx-ReqToken,Keep-Alive,User-Agent,X-Requested-With,If-Modified-Since,Cache-Control,Content-Type,Authorization';

			if ($request_method = 'OPTIONS') {
				return 204;
			}

2021年10月29日修改
之前运行的好好的，不会报404
vue-element-admin 打包部署到Nginx报404，接口无法访问，原因是重复拼接了地址，原来是没有配代理，以前没配置又可以运行，百度之后看到的：

https://bbs.csdn.net/topics/399168882?list=lz

nginx同时代理vue前端和后台就可以了

        server {
        listen       8081;
        server_name  localhost;
        root         /var/local/central/central_web/;
        index        index.html;
 
      #前端路径代理
       location /exam {
            root   html;
            index  index.html index.htm;
			
        }
       #后台路径代理
        location /api/ {
            proxy_pass http://localhost:8760;
            add_header 'Access-Control-Allow-Origin' '*'; 
            add_header 'Access-Control-Allow-Credentials' 'true'; 
        }

所以根据实际情况我是这样配置的
这是我的前端工程，是这么写的

这样子设置了
前端就不会请求不到接口了。。。

打包vue生产好像还要去掉mock的数据，忘了在哪里了。。。

最后还需要配置入站规则：https://jingyan.baidu.com/article/870c6fc3132bebb03fe4be29.html
我这边是公司自己的服务器，还需要配置路由映射，具体根据实际情况配置。
