Struct ntex::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 ntex 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

use ntex::web::App;
use ntex::web::middleware::Logger;

fn main() {
    std::env::set_var("RUST_LOG", "ntex=info");
    env_logger::init();

    let app = App::new()
        .wrap(Logger::default())
        .wrap(Logger::new("%a %{User-Agent}i"));
}

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 (in rfc3339 format)

%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

%U Request URL

%{FOO}i request.headers[‘FOO’]

%{FOO}o response.headers[‘FOO’]

%{FOO}e os.environ[‘FOO’]
