linux命令行抓取网页快照图片，网页转pdf, 支撑flash显示-（xvfb+CutyCapt / wkhtmltopdf）

Install cutycapt and headless webkit on Ubuntu to take screenshots of other websites Just type ./install and it should install all the necessary libraries for you. At the last step, it will also take a screenshot of google and output it to example.png to see that everything worked.

install.sh：

#!/bin/bash
echo "now installing cutycapt"

sudo apt-get update -y
sudo apt-get install build-essential -y
sudo apt-get install xvfb -y
sudo apt-get install xfs xfonts-scalable xfonts-100dpi -y
sudo apt-get install libgl1-mesa-dri -y
sudo apt-get install subversion libqt4-webkit libqt4-dev g++ -y

mkdir ~/scripts
cd ~/scripts
svn co https://cutycapt.svn.sourceforge.net/svnroot/cutycapt
cd cutycapt/CutyCapt

qmake
make

xvfb-run --server-args="-screen 0, 1024x768x24" ./CutyCapt --url=http://www.google.com --out=example.png

或者

xvfb（在命令行下实现对X-server的模拟，渲染图形进行缓存）-在没有安装X-Server的环境下提供图像渲染
CutyCapt（模拟浏览器对网页进行下载、HTML、css渲染、Javascript执行，并将最终渲染完成的网页进行快照）- 主力干将

Qt（CutyCapt是基于此框架开发的）

实践：

1.安装CutyCapt、Qt及相关软件包：

sudo apt-get install subversion libqt4-webkit libqt4-dev g++
svn co https://cutycapt.svn.sourceforge.net/svnroot/cutycapt
cd cutycapt/CutyCapt
qmake
make

2.安装xvfb：

apt-get install xvfb

3.抓取测试：

xvfb-run –server-args="-screen 0, 1024×768x24" ./CutyCapt –url=http://www.zol.com.cn –out=zol.png

或者

cutycapt --url="http://google.com" --out=./google.jpg

3、安装中文字库＃很多体系是没有中文的，所以你要安装中文字库，不然网页会显示方块的

sudo apt-get install ttf-arphic-ukai ttf-arphic-uming
sudo apt-get install ttf-wqy-zenhei
sudo fc-cache -v

4、安装flash插件＃如今web网站很多多少都有flash，为了别呈现一个方块，就顺手安装上吧

sudo apt-get install flashplugin-nonfree
