ngx.status ---------- **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*\* 读写当前请求的响应状态码。这个方法需要在发送响应头前调用。 ```lua ngx.status = ngx.HTTP_CREATED status = ngx.status ``` 在发送响应头之后设置 `ngx.status` 不会生效，且 nginx 的错误日志中会有下面一条记录： attempt to set ngx.status after sending out response headers > English Source **context:** *set_by_lua*\**, rewrite_by_lua*\**, access_by_lua*\**, content_by_lua*\**, header_filter_by_lua*\**, body_filter_by_lua*\**, log_by_lua*\* Read and write the current request's response status. This should be called before sending out the response headers. ```lua ngx.status = ngx.HTTP_CREATED status = ngx.status ``` Setting `ngx.status` after the response header is sent out has no effect but leaving an error message in your nginx's error log file: attempt to set ngx.status after sending out response headers [Back to TOC](#nginx-api-for-lua)
