javascript - 下载基于Content-Type JavaScript Casperjs的链接

Question

我是 CasperJS 的初学者程序员，我正在编写一个爬虫来收集网站上的每个链接，我希望根据内容类型进行下载。

var links = this.evaluate(function() {
    var links = [];
    Array.prototype.forEach.call(__utils__.findAll('a'), function(e) {
        links.push(e.getAttribute('href'));
    });
    return links;
});

Array.prototype.forEach.call(links, function(link) {
    //get content-type of link 
    //download based on context type ie. images or text
});

Answer 1

casper.on("resource.received", function(response){
   "use strict";
    resourcesRec.push(response);
    var file = response.url.replace(/^.*[\\\/]/, '');
    casper.download(response.url,file);
});
