[−][src]Struct actix_web::middleware::Logger
Middleware
for logging request and response info to the terminal.
Logger
middleware uses standard log crate to log information. You should

package to see access log.
(env_logger
or similar)
Usage
Create Logger
middleware with the specified format
.
Default Logger
could be created with default
method, it uses the
default format:
%a "%r" %s %b "%{Referer}i" "%{User-Agent}i" %T
extern crate env_logger; use actix_web::middleware::Logger; use actix_web::App; fn main() { std::env::set_var("RUST_LOG", "actix_web=info"); env_logger::init(); let app = App::new() .middleware(Logger::default()) .middleware(Logger::new("%a %{User-Agent}i")) .finish(); }
Format
%%
The percent sign
%a
Remote IP-address (IP-address of proxy if using reverse proxy)
%t
Time when the request was started to process
%r
First line of request
%s
Response status code
%b
Size of response in bytes, including HTTP headers
%T
Time taken to serve the request, in seconds with floating fraction in
.06f format
%D
Time taken to serve the request, in milliseconds
%{FOO}i
request.headers['FOO']
%{FOO}o
response.headers['FOO']
%{FOO}e
os.environ['FOO']
