nginx的使用，反向代理解决跨域问题

本篇介绍的是在window环境下的使用

首先下载nginx。下载地址

下载安装之后就可以运行了

start nginx    //运行nginx

nginx -s reload    //重启nginx，每次修改配置后都要重启

主要是nginx的配置，下面是nginx.conf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 {
    client_max_body_size 200m;#上传文件大小
    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;

    include D:/nginx/nginx-1.18.0/sliceconf/*.conf;#分片的配置文件



    # # 9519-9529 
    # server {
    #     listen       9519;#MobileGadgets
    #     server_name  localhost;
    #     # api
    #     location /apiurl/ {
    #         proxy_pass http://localhost:49628/api/;
    #     }
    #     location /signalr {
    #         #测试
    #         proxy_pass http://localhost:54398/api/signalrhub/mysendall/chatHub;
    #         proxy_set_header   Upgrade $http_upgrade;
    #         proxy_set_header   Connection upgrade;
    #         proxy_http_version 1.1;
    #         proxy_ssl_server_name on;
    #     }
    #     # 页面
    #     location / {
    #         proxy_pass   http://localhost:9529/;
    #     }
        
    #     error_page   500 502 503 504  /50x.html;
    #     location = /50x.html {
    #         root   html;
    #     }
    # }

}

可以代理的端口可以全部写在此文件夹下，写多个server即可。也可以拆分配置

上面代码中的include指向拆分的配置文件，子配置文件如下

server {
        listen       8082;
        server_name  localhost;

        #charset koi8-r;

        #access_log  logs/host.access.log  main

        location /apiurl/ {#接口代理
            proxy_pass   http://196.0.0.1:4523/mock/88888/;
        }

        location / {
            # root   web;#可以是nginx文件夹下的
            root   E:/项目文件/发布文件/Map_gy;
            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;
        }
    }
