Python mysql 池连接 fetchall 函数 return 'u' 数组中的关键字

Question

python MySQL 池返回数组中的 'u' 键，就像 - [{u'data': u'{"no_comment":1,"total_reply":2}'}]

要求的回复应该是 - [{"data": {"no_comment":1,"total_reply":2}}].

查询 - "select data from tbl_comment where id = 10"

参考代码 -

def query(_db_config, _sql, _args):
   conn = get_pool_connection(_db_config)
   if not isinstance(conn, PooledMySQLConnection):
      cursor = conn.cursor(MySQLdb.cursors.DictCursor)
   else:
      cursor = conn.cursor(dictionary=True)
   result = ()
   try:
      cursor.execute(_sql, _args)
      result = cursor.fetchall()
   except:
     pass
     rootLogger.error("query exception sql is %s ,_args is %s,stacks is %s", _sql, _args, get_caller_info_total())
     rootLogger.exception("message")
   finally:
     cursor.close()
     conn.close()
   return result

你可以这样试试：

SELECT column1, CAST(CONVERT(column2 USING utf8) AS binary)
FROM my_table
WHERE my_condition;
