python学习之故障记录

以下为我编程期间遇到的错误并进行记录，起始时间2017-6-21

----------------------------------------
Exception happened during processing of request from (‘127.0.0.1‘, 48039)
Traceback (most recent call last):
  File "/opt/python3/lib/python3.6/socketserver.py", line 639, in process_request_thread

    self.handle()
  File "/root/python_study/high_ftp/core/main.py", line 84, in handle
    recv_cmd = self.request.recv(1024).decode()
UnicodeDecodeError: ‘utf-8‘ codec can‘t decode byte 0xd3 in position 1: invalid continuation byte
发现计算文件大小使用了len，使用方式不对。修改使用了os.path.getsize计算

    new_file_md5 = m.hexdegest()
AttributeError: ‘_hashlib.HASH‘ object has no attribute ‘hexdegest‘
拼写错误了

Traceback (most recent call last):

    out = func(mess)
TypeError: get() takes 1 positional argument but 2 were given
原因是：发现我定义了2个同名的函数，导致出错

Traceback (most recent call last):
  File "D:/1_oldboyS14_Py/Advance4/homework/Adv_ftp/high_ftp/ftpclient/ftpclient_core.py", line 123, in

    if recv_msg[‘id‘] == ‘200‘:
TypeError: string indices must be integers
类型错误

应该发送时候转换为字符串发送

文件打开读取就是rb模式，所以这里不用在encode了

TypeError: argument of type ‘socket‘ is not iterable
写错了
应该是：if s is self.server: 写成 if s in self.server 新手都会这样
