使用Nginx配置代理后端接口

nginx的nginx.conf文件配置如下：

#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       8088;
        server_name  localhost;
		
        #charset koi8-r;
        #access_log  logs/host.access.log  main;
		
		location / {
          proxy_pass  http://127.0.0.1:9528;
        }

        location /dev/api/ {
		  add_header Access-Control-Allow-Origin *;
		  add_header Access-Control-Allow-Methods 'GET,POST,OPTIONS,PUT,DELETE';
		  add_header Access-Control-Allow-Headers 'Token,DNT,X-Mx-ReqToken,keep-Alive,User-Agent,X-Requested-With,If-Modified-Since,Cache-Control,Content-Type,Authorization';
          proxy_pass  https://www.xxxx:5002/api/;  #这里填上服务器地址
        }
		
		#location / {
        #  try_files $uri $uri/ /index.html;
        #}
		
        #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;
        #}
    }


    # 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;
    #    }
    #}

}

然后浏览器输入http://localhost:8088 打开项目，看下接口是否调成功；

关于Nginx代理前后端接口

最近在开发公司的前后端分离的项目，前端使用Vue,后端使用SpringBoot,本来我是想用Vue的代理功能，去请求后端接口，但是不知道死活代理不同。

proxy: {
    '/api': {
         target: 'http://127.0.0.1:8981/api/',
          pathRewrite: {
        '^/api': '/'
   }
}

这样的写法各种出现问题，比如404等问题。

后来问了一下我们公司的老员工，他说现在不建议这么配。直接用Nginx代理前后端就好。

# 代理前端的地址
location /data-pages {
    proxy_pass  http://localhost:8021/data-pages/;
}

# 代理后端地址
location /api/ {
    proxy_pass http://localhost:28090/api/;
}

之前我想的是，Vue用的是8021端口，所以后端请求过去就会变成 http://localhost:8021/api/,但是其实不是这样的。后端地址是看浏览器中的url然后拼接过去的。所以经过Nginx代理之后，后端的接口也能通过Nginx代理，这样就能解决问题。

总结

以上为个人经验，希望能给大家一个参考，也希望大家多多支持。
