加载网页，执行其JavaScript并将生成的HTML转储到文件中 [英] Load a web page, execute its JavaScript and dump resulting HTML to a file

问题描述

我需要加载一个网页，执行它的JavaScript（以及标签中包含的所有js文件）并将生成的HTLM转储到文件中。这需要在服务器上完成。我已经尝试过使用zombie.js的node.js，但似乎在现实世界中工作太不成熟了。真的浏览器（FireFox）对页面没有任何问题时，通常会抛出一个虚假的异常。

I need to load a web page, execute its JavaScript (and all js files included with the tags) and dump resulting HTLM to a file. This needs to be done on the server. I have tried node.js with zombie.js but it seems it is too immature to work in the real world. More often than not it just throws a bogus exception while a real browser (FireFox) has no issues with the page.

我的node.js代码是：

My node.js code is:

var zombie = require("zombie"),
    sys = require('sys');

// Load the page
var browser = new zombie.Browser({ debug: false });
browser.visit('http://www.dba.dk', function (error, browser, status) {
    if (error) { console.log('Error:' + error.message); }
    if (!error && browser.statusCode == 200) {
        sys.puts(browser.html);
    }
});

并退出时出现异常TypeError：无法调用方法'toString'为null

and it exits with an exception "TypeError: Cannot call method 'toString' of null"

Jaxer实际上不是一个选项..我需要下载第三方页面并在我的服务器上执行它。如何使用Jaxer

Jaxer is not really an option.. I need to download a 3rd party page and execute it on my server. How would I do that with Jaxer

推荐答案

也许这是因为您使用的是 err.message 而错误未定义？ 错误，另一方面，是定义的。

Perhaps that’s because you are using err.message whereas err is not defined? error, on the other hand, is defined.

更新

您是否查看了 PhantomJS ？

此外，它看起来像 Aptana Jaxer 可以做你想要的。引用 John Resig ：

Also, it looks like Aptana Jaxer could do what you want. To quote John Resig:

想象一下，扯掉Firefox的视觉
渲染部分和
替换它来代替Apache
的钩子 - 粗略地说是
Jaxer是。

Imagine ripping off the visual rendering part of Firefox and replacing it with a hook to Apache instead - roughly speaking that's what Jaxer is.
