[][src]Struct actix_web::middleware::Logger

pub struct Logger { /* fields omitted */ }

Middleware for logging request and response info to the terminal.

Logger middleware uses standard log crate to log information. You should enable logger for actix_web 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:

This example is not tested
 %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']

Methods
