ngx.resp.get_headers

语法: headers = ngx.resp.get_headers(max_headers?, raw?)

环境: set_by_lua*, rewrite_by_lua*, access_by_lua*, content_by_lua*, header_filter_by_lua*, body_filter_by_lua, log_by_lua*

返回一个 Lua 表，包含当前请求的所有响应头信息。

 local h = ngx.resp.get_headers()
 for k, v in pairs(h) do
     ...
 end

此函数与 ngx.req.get_headers 有相似之处，唯一区别是获取的是响应头信息而不是请求头信息。

这个 API 最早出现在 v0.9.5 版中。
