ngx.worker.pid

语法: pid = ngx.worker.pid()

语法: set_by_lua, rewrite_by_lua*, access_by_lua*, content_by_lua*, header_filter_by_lua*, body_filter_by_lua*, log_by_lua*, ngx.timer., init_by_lua, init_worker_by_lua**

这个函数返回一个Lua数字，它是当前 Nginx 工作进程的进程 ID （PID）。这个 API 比 ngx.var.pid 更有效，ngx.var.VARIABLE API 不能使用的地方（例如 init_worker_by_lua），该 API 是可以的。

该 API 在 v0.6.0 版本首次引入。

English source:

ngx.worker.pid

syntax: pid = ngx.worker.pid()

context: set_by_lua, rewrite_by_lua*, access_by_lua*, content_by_lua*, header_filter_by_lua*, body_filter_by_lua*, log_by_lua*, ngx.timer., init_by_lua, init_worker_by_lua**

This function returns a Lua number for the process ID (PID) of the current Nginx worker process. This API is more efficient than ngx.var.pid and can be used in contexts where the ngx.var.VARIABLE API cannot be used (like init_worker_by_lua).

This API was first introduced in the 0.9.5 release.
