content_by_lua -------------- **语法：** *content_by_lua &lt;lua-script-str&gt;* **环境：** *location, location if* **阶段：** *content* 作为"内容处理程序"，为每一个请求执行`<lua-script-str>`中指定的Lua代码。 这些 Lua 代码可以调用[全部 API](#nginx-api-for-lua)，并作为一个新的协程，在一个独立的全局环境中执行（就像一个沙盒）。 不要将本指令和其他内容处理程序指令放到同一个location中。 比如，本指令和[proxy_pass](http://nginx.org/en/docs/http/ngx_http_proxy_module.html#proxy_pass)指令就不能在同一个location中使用。 [返回目录](#directives) <!-- review by WenMing --> > English Source **syntax:** *content_by_lua &lt;lua-script-str&gt;* **context:** *location, location if* **phase:** *content* Acts as a "content handler" and executes Lua code string specified in `<lua-script-str>` for every request. The Lua code may make [API calls](#nginx-api-for-lua) and is executed as a new spawned coroutine in an independent global environment (i.e. a sandbox). Do not use this directive and other content handler directives in the same location. For example, this directive and the [proxy_pass](http://nginx.org/en/docs/http/ngx_http_proxy_module.html#proxy_pass) directive should not be used in the same location. [Back to TOC](#directives)
