 To read the request body data within the [$request_body](http://nginx.org/en/docs/http/ngx_http_core_module.html#var_request_body) variable,
 [client_body_buffer_size](http://nginx.org/en/docs/http/ngx_http_core_module.html#client_body_buffer_size) must have the same value as [client_max_body_size](http://nginx.org/en/docs/http/ngx_http_core_module.html#client_max_body_size). Because when the content length exceeds [client_body_buffer_size](http://nginx.org/en/docs/http/ngx_http_core_module.html#client_body_buffer_size) but less than [client_max_body_size](http://nginx.org/en/docs/http/ngx_http_core_module.html#client_max_body_size), Nginx will buffer the data into a temporary file on the disk, which will lead to empty value in the [$request_body](http://nginx.org/en/docs/http/ngx_http_core_module.html#var_request_body) variable.
