PhantomJS is a headless WebKit scriptable with a JavaScript API. It has fast and native support for various web standards: DOM handling, CSS selector, JSON, Canvas, and SVG.

开搞，代码实现如下。

var page = require('webpage').create();
var fs = require("fs");
page.settings.userAgent = 'Mozilla/5.0 (iPhone; CPU iPhone OS 8_0 like Mac OS X) AppleWebKit/600.1.3 (KHTML, like Gecko) Version/8.0 Mobile/12A4345d Safari/600.1.4';
page.open('http://ui.ptlogin2.qq.com/cgi-bin/login?pt_no_onekey=1&style=9&appid=1006102&s_url=http%3A%2F%2Fxiaoqu.qq.com%2Fmobile%2Fbarindex.html%3F_lv%3D29313%26_bid%3D128%26_wv%3D1027%26from%3Dshare_link%23bid%3D37469%26type%3D%26source%3Dindex%26scene%3Drecent%26from%3Ddongtai%26webview%3D1&low_login=0&hln_css=http%3A%2F%2Fpub.idqqimg.com%2Fqqun%2Fxiaoqu%2Fmobile%2Fimg%2Fnopack%2Flogin-logo.png', function(status){
    if (status == 'success') {
        page.render('index.png');
        setTimeout(function() {
            page.evaluate(function() {
                document.getElementById('u').value = 'QQ号码';
                document.getElementById('p').value = 'QQ密码';
                pt.check(false);
                //document.getElementById('go').click(); //pt.check()或.click()
            });
            setTimeout(function() {
                file = fs.open("cookie.log", 'w');
                file.write(JSON.stringify(page.cookies));
                file.close();
                phantom.exit();
            }, 2000);
        }, 1000);
    }
});

cookie会写入到当前目录下的cookie.log文件，有了cookie接下来的事情就简单多了。使用php或js将cookie种到浏览器下即可。

1. 安装步骤

1.1 在服务器上新建想要下载和安装的目录：

如mkdir  PhantomJS

1.2 下载PhantomJS安装包

wget https://bitbucket.org/ariya/phantomjs/downloads/phantomjs-2.1.1-linux-x86_64.tar.bz2

 

 

执行结果如下图：

1.3 解压工具包

tar -xjvf phantomjs-2.1.1-linux-x86_64.tar.bz2

 

执行时报如下错误：

tar (child): cannot run bzip2: No such file or directory

出现上述错误，请安装bzip2

执行指令：

 

yum -y install bzip2

 

再次执行解压指令：

成功完成解压。

1.4 将可执行文件放入系统路径

sudo ln -s ~/phantomjs-2.1.1-linux-x86_64/bin/phantomjs /usr/bin/phantomjs

 

1.5 安装依赖——fontconfig和freetype：

yum install fontconfig

 

yum install freetype

 



1.6 在终端下测试Phantomjs

注意系统目录为/usr/bin/
至此成功

Centos 安装v8js

yum install php-pear

yum install re2c

yum install v8-devel

pecl install v8js-0.1.3
// if failed, need to download v8js-0.1.3 and manually install it

// modify b8js.cc and add the blow info line 1

#define PHP_V8_VERSION “0.1.3”

phpize
./configure –with-v8js

系统自带的libv8版本太低了。

sudo add-apt-repository ppa:pinepain/libv8
sudo apt-get update

 

卸載原先的libv8-dev,執行apt-get install libv8-6.6-dev

nice

使用CentOS系统的时候，经常会遇到系统日志文件非常大的情况，如果直接删除，会导致日志错误，不再生成日志，这时，我们可以使用下面的方法清空日志。

* [Centos6]
* [Centos7]

CentOS 6系统

cat /dev/null > /var/log/boot.log
cat /dev/null > /var/log/btmp
cat /dev/null > /var/log/cron
cat /dev/null > /var/log/dmesg
cat /dev/null > /var/log/dracut.log
cat /dev/null > /var/log/lastlog
cat /dev/null > /var/log/maillog
cat /dev/null > /var/log/messages
cat /dev/null > /var/log/secure
cat /dev/null > /var/log/spooler
cat /dev/null > /var/log/tallylog
cat /dev/null > /var/log/wtmp
cat /dev/null > /var/log/yum.log

CentOS 7系统

cat /dev/null > /var/log/boot.log
cat /dev/null > /var/log/btmp
cat /dev/null > /var/log/cron
cat /dev/null > /var/log/dmesg
cat /dev/null > /var/log/firewalld
cat /dev/null > /var/log/grubby

cat /dev/null > /var/log/tallylog
cat /dev/null > /var/log/wpa_supplicant.log

Debian安装 aria2

为什么是Debian？？因为我的树莓派用的是debian!23333~~~~

aria2 一个方便的下载工具，支持  HTTP/HTTPS, FTP, SFTP, BitTorrent 和Metalink 。可以通过内置的 JSON-RPC 和XML-RPC 接口来使用。参考 github 项目aria2

注意这里使用 Debian进行搭建。不要使用 centos，为什么呢？因为centos 上好多对应的依赖包都找不到，软件版本过低等问题。如果你硬要搭建，可以参考 Centos6编译安装最新Aria2 1.27.1——带你临近网速极限。 浏览全部 →
