phantomjs

phantomjs是與zomebie功能相仿的一個模擬瀏覽器操控套件，比較不一樣的地方是，phantomjs提供一些指令(CLI)操作的方式，比較詳細的說明可以參考phantomjs官網。

Sample Usage

console.log('Loading a web page');
var page = require('webpage').create();
var url = 'http://www.phantomjs.org/';
page.open(url, function (status) {
    //Page is loaded!
    phantom.exit();
});

上面程式的執行方式不同於一般node.js執行的方式，而是要透過phantomjs這個指令來執行...

另外，展示個透過phantomjs來做網頁快照的方式：

console.log('Loading a web page');
var page = require('webpage').create();
var url = 'http://www.phantomjs.org/';
page.open(url, function (status) {
    //Page is loaded!
    page.render('phantomjs.png');
    phantom.exit();
});

執行方式與結果如下：

$ phantomjs examples/phantomjs/sample01.js
Loading a web page

$ ls -l phantomjs.png
-rw-r--r--  1 simonsu  staff  162493  8 21 11:52 phantomjs.png

phantomjs有許多其他的應用，喜歡phantomjs的朋友可以參考官網或是phantomjs的github上的教學與範例喔!
