使用Python编写一个在Linux下实现截图分享的脚本的教程
引子
Linux下不支持QQ等功能丰富的IM,虽然可以通过wine运行QQ2012,但是还是喜欢在gtalk群中聊天,gtalk群不支持图片方式,这就要靠我们大家自己来解决了,eleven开放了一个Image上传和显示接口,提供了使用curl来解决,但是我们公司的网络使用squid禁止了curl的访问,所以整天看他们这么爽的分享图片我也不甘心阿,所以就使用Python写了一个分享图片的脚本
实现
使用scrot截图,然后使用urllib2库上传图片,如果存在PyQt4库则会将结果放到剪贴板上,如果不存在则输出,自行复制

安装
将上面代码保存一个文件,放在PATH路径里,赋予执行权限即可
使用
默认的不跟图片地址则会截图,截图完毕后自动分享,如安装了PyQt4库则会将结果放到剪贴板,如没有则输出结果.如果脚本给了图片路径参数则上传给定路径的图片
