类如含有@之类的特殊符号,在链接数据库时,需要提前url转码,不然会报密码错误。
python3/2分别引用是同样的第三方库,但是引用方式不同
python2
from urllib import quote_plus as urlquote
password = urlquote('password')
db_data = pymysql.connect(host='127.0.0.1',user='root'.password = password,db = 'test',port=3306,charser='utf8')
到了python3,quote_plus成了parse的函数
python3
from urllib import parse
password = parse.unquote_plus('password')
db_data = pymysql.connect(host='127.0.0.1',user='root'.password = password,db = 'test',port=3306,charser='utf8')
