具体详解

nginx监听端口

在server下加入

 underscores_in_headers on;
        listen       11399;
        server_name  localhost;
        client_max_body_size 300m;

解决跨域问题

在server下加入

        location / {
          add_header 'Access-Control-Allow-Origin' '*'; #这里必须指定为$http_orgin，明确指定可以跨域请求的域名，替代*
    	  add_header 'Access-Control-Allow-Headers' '*';
    	  add_header 'Access-Control-Allow-Methods' "GET,POST,PUT,DELETE,OPTIONS,FM";
          root   E:\\platform\\dist;
          index  index.html index.htm;
		  try_files $uri $uri/ /index.html;
        }

具体如何实现映射

在server下加入

		# 将G:和/3ddata拼接，而不是将/3ddata替换成G:
		location /3ddata {
		    include nginx_cors; 
            root G:;  
            index  index.html index.htm;
            expires 30d;
		}

一要注意是拼接而不是替换

在某个文件夹下实现文件目录

在server下的location /3ddata中加入
一些参数说明：
autoindex on; # 开启目录文件列表
autoindex_exact_size on; # 显示出文件的确切大小，单位是bytes
autoindex_localtime on; # 显示的文件时间为文件的服务器时间
charset utf-8; # 避免中文乱码

另外，如果希望请求文件是下载而不是显示内容，可以通过添加下面参数实现：
add_header Content-Disposition attachment;
如：

		# 将G:和/3ddata拼接，而不是将/3ddata替换成G:
		location /3ddata {
		    include nginx_cors; 
            root G:; 
            autoindex on; # 开启目录文件列表
            autoindex_exact_size on; # 显示出文件的确切大小，单位是bytes
            autoindex_localtime on; # 显示的文件时间为文件的服务器时间
            charset utf-8; # 避免中文乱码 
            index  index.html index.htm;
            expires 30d;
		}

常见命令

nginx.exe -s stop

nginx.exe -s reload

nginx.exe
