网关除了要服务转发外，还需要包含限流，鉴权等其他一些功能；需要进一步开发；

proxy_cache_path  /data/nginx_cache levels=1:2 keys_zone=proxycache:60m max_size=120m inactive=2h use_temp_path=off;
proxy_cache_key    $host$request_uri;
proxy_cache proxycache;


 add_header    Cache-Control  public,max-age=3600;
 proxy_ignore_headers  Cache-Control;

proxy_cache_path:
1. keys_zone: create a shared memory zone for storing the cache key
2. max_size: the cache max size
3. how long an item can remain in the cache without being accessed.
