一、背景
把手机上的文件传到PC;
原因：手机存储太小
矛盾：
1.不想安装乱七八糟的软件;
2.不想安装手机助手,不想插USB;
3.不想用社交软件QQ、微信、钉钉等传文件;
那么能不能自己做一个简单工具呢
答案：可以，正好PC有python3环境作为服务端，手机端使用浏览器访问html上传文件。
结果：最终手机端用QQ浏览器尝试成功，一次上传200张图片都没有问题。

使用方法
直接访问"http://192.168.1.123:8085/"即可，其中192.168.1.123是PC机的IP。
手机端
很遗憾，大多数手机浏览器不支持多选，只有QQ和Chrome两款手机浏览器支持。
QQ浏览器84MB，Chrome94MB,其中Chrome在应用商店还找不到。
强忍着QQ浏览器恶心的各种垃圾推送完成了测试。
三、问题和解决方法
1.如何修改监听端口？
http.server.test(HandlerClass, ServerClass, "HTTP/1.0", 8085) #修改simple.py这句中的8085
2.如何修改上传目录
#simple.py中把path = self.translate_path(self.path)改成自己的目录即可
path = /home/upload/
3.上传没有反应或报错"Provisional headers are shown"
跨域问题导致的,在index.html中,将如下部分改成自己PC的地址
// 文件接收服务端。
server: ‘http://192.168.1.123:8085/‘,
4.手机上不能多选图片
答：目前支持多选的浏览器只有QQ浏览器和chrome浏览器。
