Mysql爬取数据时,未转义报错
代码信息
for i in range(0,len(records)):
author = records[i]['author']
userId = author['userId']
userName = author['name']
postTime = records[i]['createTime']
sql = "REPLACE INTO userinfo (userId, userName, postTime) VALUES ('%s', '%s', '%s')"
data = (userId, userName, postTime)
try:
cursor.execute(sql % data)
connect.commit()
except :
print(userId,userName,userName)
报错信息
ProgrammingError: (1064, "You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'm mi fan')' at line 1")
博主在爬取时,存储用户名时遇到用户名I'm mi fan
的,会出现以上报错,原因是这个符号未转义'
加入代码userName1 = replace("'","\\'")
即可
原因如下
I'm mi fan
中存储时变成I\'m mi fan
即可将'
转义
但python环境中,使用replace函数插入\
防止python讲该字符当成转义符,需要加两个,即replace("'","\\'")
最终代码呈现
for i in range(0,len(records)):
author = records[i]['author']
userId = author['userId']
userName = author['name']
postTime = records[i]['createTime']
sql = "REPLACE INTO userinfo (userId, userName, postTime) VALUES ('%s', '%s', '%s')"
userName1 = userName.replace("'","\\'")
data = (userId, userName1, postTime)
try:
cursor.execute(sql % data)
connect.commit()
except :
print(userId,userName,userName1)
