Vue代理模式和Nginx反向代理(Vue代理部署不生效)

在使用axios时，经常会遇到跨域问题。为了解决跨域问题，可以在 vue.config.js 文件中配置代理： const { defineConfig } = require('@vue/cli-service') module.exports = defineConfig({ transpileDependencies: true, devServer: { port: 7070, proxy: { '/api': { target: 'http://localhost:8080/admin', pathRewrite: { '^/api': '' } } } } }) axios的post请求示例： axios.post('/api/employee/login',{ username:'admin', password: '123456' }).then(res => { console.log(res.data) }).catch(error => { console.log(error.response) })

前端发送：http://localhost:7070/api/employee/login 经过代理转换为：http://localhost:8080/admin/employee/login

axios的get请求示例： axios.get('/api/shop/status',{ headers: { token: ‘xxx.yyy.zzz’ } })

前端发送：http://localhost:7070/api/shop/status 经过代理转换为：http://localhost:8080/admin/shop/status

打包部署vue npm run build

打包结束后生成dist文件夹

注意：打包时这个代理并不会跟着打包

假设我们将项目打包到的nginx地址是localhost地址，访问端口是80（80默认可省略）

那么这时候数据请求将请求的是http://localhost/api/employee/login地址，但是我们需要请求的接口是localhost:8080地址，这时候就需要用到nginx的反向代理了 。

首先进入配置文件

#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; map $http_upgrade $connection_upgrade{ default upgrade; '' close; } upstream webservers{ server 127.0.0.1:8080 weight=90 ; #server 127.0.0.1:8088 weight=10 ; } server { listen 80; server_name localhost; #charset koi8-r; #access_log logs/host.access.log main; location / { root html/sky; index index.html index.htm; } #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; } # 反向代理,处理管理端发送的请求 location /api/ { proxy_pass http://localhost:8080/admin/; #proxy_pass http://webservers/admin/; } # 反向代理,处理用户端发送的请求 location /user/ { proxy_pass http://webservers/user/; } # WebSocket location /ws/ { proxy_pass http://webservers/ws/; proxy_http_version 1.1; proxy_read_timeout 3600s; proxy_set_header Upgrade $http_upgrade; proxy_set_header Connection "$connection_upgrade"; } # 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; #} } # another virtual host using mix of IP-, name-, and port-based configuration # #server { # listen 8000; # listen somename:8080; # server_name somename alias another.alias; # location / { # root html; # index index.html index.htm; # } #} # HTTPS server # #server { # listen 443 ssl; # server_name localhost; # ssl_certificate cert.pem; # ssl_certificate_key cert.key; # ssl_session_cache shared:SSL:1m; # ssl_session_timeout 5m; # ssl_ciphers HIGH:!aNULL:!MD5; # ssl_prefer_server_ciphers on; # location / { # root html; # index index.html index.htm; # } #} }

配置好了代理之后就可以重启服务器了 nginx将http://localhost/api/employee/login 转为http://localhost:8080/admin/employee/login
