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。 ```lua local h = ngx.resp.get_headers() for k, v in pairs(h) do ... end ``` 此函数与 [ngx.req.get_headers](#ngxreqget_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。 > English Source **syntax:** *headers = ngx.resp.get_headers(max_headers?, raw?)* **context:** *set_by_lua*\**, rewrite_by_lua*\**, access_by_lua*\**, content_by_lua*\**, header_filter_by_lua*\**, body_filter_by_lua, log_by_lua*\* Returns a Lua table holding all the current response headers for the current request. ```lua local h = ngx.resp.get_headers() for k, v in pairs(h) do ... end ``` This function has the same signature as [ngx.req.get_headers](#ngxreqget_headers) except getting response headers instead of request headers. This API was first introduced in the `v0.9.5` release. [返回目录](#nginx-api-for-lua)
