Use Nginx in vue.js to solve cross-domain issues

Below I will share with you an article about using vue.js proxy and using Nginx to solve cross-domain problems. It has a good reference value and I hope it will be helpful to everyone.

Use Nginx reverse proxy to solve cross-domain problems (vue.js uses a proxy to remove options requests triggered by vue.js due to cross-domain)

Our project still requires node.js as a container ’s

1. Install Nginx under Windows (Download the stable version from the official website http://nginx.org/en/download.html)

2. Modify the server of the nginx.conf file in the config

server { 
listen 8899;// 你的端口 
server_name localhost; 
root C:/ZOBSF_F/dist;//你打包部署的文件路径 
#charset koi8-r; 
#access_log logs/host.access.log main; 
# 匹配 api 路由的反向代理到API服务 
location ^~/api { 
proxy_pass http://119.23.227.141:10001/;//你的后端IP和端口 
} 
#根据路由设置，避免出现404 
location / { 
try_files $uri $uri/ @router; 
index index.html; 
} 
location @router { 
rewrite ^.*$ /index.html last; 
} 
#error_page 404 /404.html; 
# redirect server error pages to the static page /50x.html 
# 
error_page 500 502 503 504 /50x.html; 
location = /50x.html { 
root html; 
} 
# proxy the PHP scripts to Apache listening on 127.0.0.1:80 
# 
#location ~ \.php$ { 
# proxy_pass http://127.0.0.1; 
#} 
# pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000 
# 
#location ~ \.php$ { 
# root html; 
# fastcgi_pass 127.0.0.1:9000; 
# fastcgi_index index.php; 
# fastcgi_param SCRIPT_FILENAME /scripts$fastcgi_script_name; 
# include fastcgi_params; 
#} 
# deny access to .htaccess files, if Apache's document root 
# concurs with nginx's one 
# 
#location ~ /\.ht { 
# deny all; 
#} 
}

3. The dist file packaged by your uve.js is as follows

## Fourth, then add a project startup configuration file server.production.js

var express = require('express');
var app = express();
var compression = require('compression');
var proxyMiddleware = require('http-proxy-middleware')
var history = require('connect-history-api-fallback');
app.use(compression());
app.use(express.static(__dirname));
app.middleware = [//使用代理api
    proxyMiddleware(['/api'], {target: 'http://192.168.11.103:10001',
    changeOrigin: true,
    pathRewrite: {
    '^/api' : '/', 
  },}),
];
app.get('*', function(req, res) {
  res.sendFile(__dirname + '/index.html');
});
app.use(history());
app.use(app.middleware);

app.listen('8080', function(error) {
  console.info("==================系统正在启动中...=============================");
 if (error) {
  console.error(error)
 } else {
  console.info("==================9999系统启动成功！！！=============================")
 }
});

5. Then use the command node server.production.js in the project directory and press Enter to find that the package lacks dependencies. Use npm install [dependency component of error message] to have express, compression, http-proxy-middleware etc.

Then start the project and access the address http://localhost:8080/xxx

Six, vue.js uses proxy Specifically, you can refer to Baidu (just modify inde.js in the config configuration file)

 proxyTable: {
     '/api': {
    target: Host.Host,//设置你调用的接口域名和端口号 别忘了加http
    changeOrigin: true,
    pathRewrite: {
     '^/api': '/'//这里理解成用‘/api'代替target里面的地址，后面组件中我们掉接口时直接用api代替 比如我要调用'http://40.00.100.100:3002/user/add'，直接写‘/api/user/add'即可
    }
   }
  },

The above is what I compiled for everyone. I hope it will be helpful to everyone in the future.
