使用Javascript和grunt将网页源文件下载到文件

我的任务有问题和疑问。 我在GruntJs上写了一些应用程序。 我必须通过gruntJs下载网页源代码。

例如,我有一个页面: example.com/index.html

我想在Grunt任务中提供URL,例如: scr: "example.com/index.html"

然后,我必须有这个源文件, ex: source.txt

我怎样才能做到这一点?

       

网上收集的解决方案 "使用Javascript和grunt将网页源文件下载到文件"

这有几个办法。

首先是注释中提到的来自node.js API的原始http.get 。 这将使您获得最初的加载页面所提供的原始资源。 问题出现时,该网站广泛使用的JavaScript来build立更多的HTML之后的Ajax请求。

第二种方法是使用实​​际的浏览器引擎来加载网站,并执行任何JavaScript和进一步的HTML构build页面加载运行。 最常见的引擎是PhantomJS ,它被包装在一个名为grunt-lib-phantomjs的Grunt库中。

幸运的是,有人已经提供了另外一层,几乎完全是你要求的: https : //github.com/cburgdorf/grunt-html-snapshot

上面的链接的示例configuration:

 grunt.initConfig({ htmlSnapshot: { all: { options: { //that's the path where the snapshots should be placed //it's empty by default which means they will go into the directory //where your Gruntfile.js is placed snapshotPath: 'snapshots/', //This should be either the base path to your index.html file //or your base URL. Currently the task does not use it's own //webserver. So if your site needs a webserver to be fully //functional configure it here. sitePath: 'http://localhost:8888/my-website/', //you can choose a prefix for your snapshots //by default it's 'snapshot_' fileNamePrefix: 'sp_', //by default the task waits 500ms before fetching the html. //this is to give the page enough time to to assemble itself. //if your page needs more time, tweak here. msWaitForPages: 1000, //if you would rather not keep the script tags in the html snapshots //set `removeScripts` to true. It's false by default removeScripts: true, //he goes the list of all urls that should be fetched urls: [ '', '#!/en-gb/showcase' ] } } } });
