python错误处理

连接数据库时的编码问题

报错

python编码错误：UnicodeDecodeError: 'utf8' codec can't decode

或者UnicodeDecodeError: 'ascii' codec can't decode byte 0xcf in position 7: ordinal not in range(128)

考虑使用如下方法http://www.jb51.net/article/59297.htm

代码如下

#coding:utf-8
import sys
reload(sys)
sys.setdefaultencoding('utf8')

import mysql.connector

cnx =mysql.connector.connect(user='bitbear',password='bittest123',host='101.201.50.1',database='bitbear',charset='utf8')

#coding:utf-8
import sys
reload(sys)
sys.setdefaultencoding('utf8')

import mysql.connector
import json as js

#f = file('./my.json')
#x=js.loads(f)
#print x

with open('./my.json', 'r') as f:
x=f.read()
print type(x)

#####

conn =mysql.connector.connect(user='bitbear',password='bittest123',host='101.201.50.1',database='bitbear',charset='utf8')

cursor = conn.cursor()

#cursor.execute('create table usertest (id varchar(20) primary key, name varchar(20))')

cursor.execute('insert into usertest1 ( name) values ( %s)', [x])

cursor.rowcount

conn.commit()

cursor.close()

使用pycharm2017+python3.6连接数据库时无法导入mysql以及mysqldb

mysqldb暂不支持python3.6，使用pymysql
