nginx 配置内容 ：
server {
listen 9999;#监听端口
server_name localhost;#域名
add_header Access-Control-Allow-Origin *; # 允许跨域
#charset koi8-r;
#access_log logs/host.access.log main;
location / {
root D:/html/index.html;#静态html项目的地址
index index.html;
autoindex off;
}
location /test/ {
#以下为Ajax中跨域配置项
add_header 'Access-Control-Allow-Origin' '*';
add_header 'Access-Control-Allow-Methods' 'GET, POST, OPTIONS';
add_header 'Access-Control-Allow-Headers' '*';
add_header 'Access-Control-Expose-Headers' 'DNT,X-CustomHeader,Keep-Alive,User-Agent,X-Requested-With,If-Modified-Since,Cache-Control,Content-Type,Content-Range,Range';
proxy_pass http://123.456.789.10:1234;# 测试请求地址为你项目具体请求地址
}
}
nginx 命令：
start nginx 启动nginx
nginx -s stop 快速关闭nginx
nginx -s reload 改变了Nginx相关配置，需要重新加载配置而重载。
