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)
