资源跨域:

法一：CORS（Cross-Origin Resource Sharing) 服务器支持

location / {
  add_header Access-Control-Allow-Origin *;
  add_header Access-Control-Allow-Methods "GET, POST, OPTIONS, PUT, DELETE";
  add_header Access-Control-Allow-Headers "Origin, X-Requested-With, Content-Type, Accept";
  if ($request_method = 'OPTIONS') {
    add_header Access-Control-Allow-Origin *;
    add_header Access-Control-Allow-Methods "GET, POST, OPTIONS, PUT, DELETE";
    add_header Access-Control-Allow-Headers "Origin, X-Requested-With, Content-Type, Accept";
    return 200;
  }
}

法二：服务器代理访问 

server {

    #nginx监听所有localhost:8080端口收到的请求
	listen       8080;
	server_name  localhost;

	# Load configuration files for the default server block.
	include /etc/nginx/default.d/*.conf;

    #localhost:8080 会被转发到这里
	#同时, 后端程序会接收到 "192.168.25.20:8088"这样的请求url
	location / {
		proxy_pass http://192.168.25.20:8088;
	}

	#localhost:8080/api/ 会被转发到这里
    #同时, 后端程序会接收到 "192.168.25.20:9000/api/"这样的请求url
	location /api/ {
		proxy_pass http://192.168.25.20:9000;
	}

	error_page 404 /404.html;
		location = /40x.html {
	}

	error_page 500 502 503 504 /50x.html;
		location = /50x.html {
	}
}

限流设置：

编辑 nginx.conf

http {
    limit_rate 250k;  # 单个请求带宽
    limit_conn_zone $binary_remote_addr zone=addr:10m; # 连接限制域
    limit_req_zone $binary_remote_addr zone=one:10m rate=20r/s;  # 单个ip请求限制速率

...

编辑 虚拟机文件 uat.conf

location ~ \.php$ {
          #limit
          limit_conn addr 50;  #单ip限制50个connections
          limit_req zone=one burst=5;  # 应用请求限制

...
