‘NoneType‘ object has no attribute ‘encoding‘

一、

问题介绍:
在写python web时访问特定网页,出现了'NoneType' object has no attribute 'encoding'错误。

二、

查看文件mini_frame.py文件(用于处理业务逻辑的文件),发现在进行数据库连接时有编码的设定。

db=pymysql.connect(host='localhost',port=3306,user='root',password='123456',database='stock_db',charset='utf-8')
cursor=db.cursor()
sql="select * from info;"
cursor.execute(sql)
data_from_mysql=cursor.fetchall()
cursor.close()
db.close()


解决:
将utf-8给改成utf8即可。

改之后的代码如下:

db=pymysql.connect(host='localhost',port=3306,user='root',password='123456',database='stock_db',charset='utf8')
cursor=db.cursor()
sql="select * from info;"
cursor.execute(sql)
data_from_mysql=cursor.fetchall()
cursor.close()
db.close()

 


Accept what was and what is, and you’ll have more positive energy to pursue what will be.
