Chrome扩展工具-二维码生成器
起因：
从事移动web开发有段时间了，有的时候往往需要用手机访问网址。开发环境下的URL一般都会超级长，用手机键盘输入确实很蛋疼。
介于通常都是用chrome调试页面，chrome拓展就是最好的解决方案。
于是这个插件横空出世，有以下两大功能：
1.即刻生成当前页面URL二维码
2.支持输入URL转换为二维码
是不是觉得很方便呢？

Cause：
Engaged in the mobile web development more than a year，we aways need to visit websites by mobile. but some times the url was very very long in the development environment,is to hard to input the url with phone keyborad.
chrome is the pouplar mobile web development tools, so the best solution is to develop a chrome extension.
qrcode has two functions
1.generated qr code for current URL
2.generated qr code for input a URL by user
