Wie folgt Javascripts Name in HTTP-Anfrage mit Node.js?

Question

Ich möchte ausgeführte javaScript-Namen von einer Webseite abrufen.

Gibt es einen Weg in Node.js mit request Modul oder anderen?

request.get('http://google.com', function(err, res, body){ 
    ... console.log(res.executedScriptNames); 
}) 

Answer 1

Sie können alle Netzwerkereignisse herausfinden, welche Inhalte vom Typ Javascript zurückkehren, eine Maden Browser. Im folgenden Beispiel verwende ich phantomjs, um die Ereignisse abzurufen, die eine Antwort vom Typ javascript auf dieser stackoverflow-Fragenseite selbst ausgelöst haben. Also, im Grunde werden wir versuchen, diese Ereignisse zu erfassen:

$ cat example.js 

"use strict"; 
var page = require('webpage').create(), 
    system = require('system'), 
    address; 

address = 'http://stackoverflow.com/q/42036173/1005215'; 

page.onResourceReceived = function (res) { 
    if (res.contentType.match(/javascript/)) { 
     console.log(res.url) 
    } 
}; 

page.open(address, function (status) { 
    if (status !== 'success') { 
     console.log('FAIL to load the address'); 
    } 
    phantom.exit(); 
}); 

$ ./node_modules/phantomjs/bin/phantomjs example.js
