插入MySQL报错‘pymysql.err.DataError: (1406, "Data too long for column 'url' at row 1")’

在插入MySQL的字符太多，此时将MySQL的模式改为非严格模式。
MySQL中运行：
mysql> SET @@global.sql_mode= ‘’;

【搬运国外大神解释】

MySQL will truncate any insert value that exceeds the specified column width.

to make this without error try Switch your MySQL mode to not use STRICT.
