VisualizaçõesHow to implement the response to the TRACE request in express.js?
The HTTP TRACE method performs a message loop-back test along the path to the target resource, providing a useful debugging mechanism. The final recipient of the request should reflect the message received back to the client as the message body of a 200 (OK) response with a Content-Type of message/http.
Example of an HTTP request with the TRACE method:
Example of a response to a request with the TRACE method:
const path = require( 'path' );
const express = require( 'express' ); // version 4.x
const favicon = require( 'serve-favicon' );
const app = express();
app .use( favicon( path.join( __dirname, 'assets', 'logo.ico' ) ) );
app.trace( '*', ( req, res ) => {
// how do I return the entire request in its original form in response?
} );

The request argument in Express is actually a modified node.js http.IncomingMessage object so you can get all the request data from it:
app.trace( '*', ( req, res ) => {
res.end(
`${req.method} ${req.url} HTTP/${req.httpVersion}\r\n` +
req.rawHeaders.join('\r\n')
)
});
This would generally re-create the request but because you are reconstructing it instead of simply copying it there may be small differences.
