【问题描述】：

class GetAdminAsJsonHandler(BaseHandler):
    def post(self):
        admin_guid = self.get_argument("admin_guid")
        if admin_guid == None:
            self.write("AdminGuid is missing.")
        else:
            database = self.connect_db()
            cursor = database.cursor()
            admins = cursor.execute("SELECT * FROM Admin").fetchall()
            self.disconnect_db()
            self.write(json_encode(admins)) # Error

嗨，我应该开发一个处理程序，当 AJAX 从 Web 请求时，它会返回数据库中的 json 编码管理员列表。使用 Pyodbc 并假设表列是 AdminGuid、ID 和 Name，我应该如何更正 #Error 部分以使其正常工作？

谢谢！！

【问题讨论】：

错误信息是什么？向我们展示整个追溯消息。
添加了错误信息。 TypeError: ('admin', 'admin', '\xc3\xd6\xb0\xed\xbf\xee\xbf\xb5\xc1\xf8', True, True, 1) 不是 JSON 可序列化的。我猜它的格式不适合转换为 JSON
