以下為我編程期間遇到的錯誤並進行記錄，起始時間2017-6-21

Exception happened during processing of request from (‘127.0.0.1‘, 48039)
Traceback (most recent call last):

    recv_cmd = self.request.recv(1024).decode()
UnicodeDecodeError: ‘utf-8‘ codec can‘t decode byte 0xd3 in position 1: invalid continuation byte
發現計算文件大小使用了len，使用方式不對。修改使用了os.path.getsize計算

拼寫錯誤了

    out = func(mess)
TypeError: get() takes 1 positional argument but 2 were given
原因是：發現我定義了2個同名的函數，導致出錯

應該發送時候轉換為字符串發送

文件打開讀取就是rb模式，所以這裏不用在encode了

TypeError: argument of type ‘socket‘ is not iterable
寫錯了
應該是：if s is self.server: 寫成 if s in self.server 新手都會這樣
