nginx 限流失败的奇怪问题

问题描述

~/info 限流失败

~info 和~/info 都能匹配到值，$limit_key_pc_page_info 的值输出 page_info

为什么加/符号会影响限流？$limit_key_pc_page_info 里面有值

1 、nginx 配置

# 变量-URI
map $uri $limit_key_pc_page_info {
	~/info "page_info";
	#~info "page_info";
	default "";
}
limit_req_zone $limit_key_pc_page_info zone=limit_zone_pc_page_info:10m rate=1r/s;

server {
	listen 80;
	server_name www.dunhanson.com;
	charset utf-8;

	location / {
		# 限流
		limit_req zone=limit_zone_pc_page_info nodelay;
		proxy_pass http://www_dunhanson_com;
	}
}

server {
	listen 80;
	server_name test.dunhanson.com;
	charset utf-8;

	location / {
		default_type text/plain;
		return 200 "$uri $limit_key_pc_page_info";
	}
}

2 、测试效果

curl http://test.dunhanson.com/info-558860051.html

输出: /info-558860051.html page_info
