执行pymysql.connect时出现错误Keyerror 255 [英] Error Keyerror 255 when executing pymysql.connect

问题描述

这是代码

import pymysql
pymysql.connect(
    host='localhost',
    port=3306,
    user='root',
    password='iDontWannaSay',
    db='iDontWannaShow',
    charset='utf8'
)

，错误回溯为:

data is :::::b'\xff\x02\x00\xff\x81\x15'....##### I was add near line 1279 which is print("data is :::::%s...."%data[i:i+6])
Traceback (most recent call last):
  File "C:\Users\123\Desktop\pymysqldebug.py", line 8, in <module>
    charset='utf8'
  File "D:\Program Files (x86)\Python\Python35\lib\site-packages\pymysql\__init__.py", line 90, in Connect
    return Connection(*args, **kwargs)
  File "D:\Program Files (x86)\Python\Python35\lib\site-packages\pymysql\connections.py", line 709, in __init__
    self.connect()
  File "D:\Program Files (x86)\Python\Python35\lib\site-packages\pymysql\connections.py", line 934, in connect
    self._get_server_information()
  File "D:\Program Files (x86)\Python\Python35\lib\site-packages\pymysql\connections.py", line 1279, in _get_server_information
    self.server_charset = charset_by_id(lang).name
  File "D:\Program Files (x86)\Python\Python35\lib\site-packages\pymysql\charset.py", line 39, in by_id
    return self._by_id[id]
KeyError: 255

好像struct.unpack方法将'\ xff \'解析为255并分配给self.server_language一样，无论传递的非null字符集参数如何.

seems like struct.unpack method parse '\xff\' to 255 and assigned to self.server_language, whatever the non-null charset argument passed.

这是MySQL版本问题吗?(版本8.0.1-dmr)

Is this an MySQL version problem?(version 8.0.1-dmr)
