开源Nodejs项目推荐:抓取网站截图

抓取网站截图

很多网页特别长,直接的电脑截图非常麻烦,用ps等工具也非常麻烦,所以很多人都问我有木有自动抓出截图的软件

Node.js里是有的

推荐pageres

首先全局安装

$ PHANTOMJS_CDNURL=https://npm.taobao.org/dist/phantomjs npm install phantomjs --registry=https://registry.npm.taobao.org --no-proxy
$ npm install --global pageres-cli

执行

效果如下

说明:此模块依赖PhantomJS,请备好梯子或者用文中的国内镜像

嵌入代码中

通过shell是可以做,这是给其他语言调用的,对于Node.js,你可以使用对应模块就好了

https://github.com/sindresorhus/pageres

$ npm install --save pageres

PhantomJS, which is used for generating the screenshots, is installed automagically, but in some rare cases it might fail to and you'll get an Error: spawn EACCES error. Download PhantomJS manually and reinstall pageres if that happens.

用法

const Pageres = require('pageres');

const pageres = new Pageres({delay: 2})
    .src('yeoman.io', ['480x320', '1024x768', 'iphone 5s'], {crop: true})
    .src('todomvc.com', ['1280x1024', '1920x1080'])
    .dest(__dirname)
    .run()
    .then(() => console.log('done'));
