源码：

conn = pymysql.Connect(host = '127.0.0.1', port = 3306, user = 'root', passwd = 'root', db = 'scrapy',charset = 'utf8')

cur = conn.cursor()

self.cur.execute('INSERT into kandian (title,content)values("1111","wwww")')

self.cur.commit()

执行提示错误：AttributeError: 'Cursor' object has no attribute 'commit'

原因：提交的应该是连接而不是游标

错误位置：self.cur.commit()

正确写法：self.conn.commit()
