BUG -- JSON字符串过长，无法解析

发布时间 2023-08-25 17:04:37作者: chenzhang-Blog

BUG产生时间：
2023/8/25

主要问题：

Message":"使用 JSON JavaScriptSerializer 进行序列化或反序列化时出错。字符串的长度超过了为 maxJsonLength 属性设置的值。“

具体原因是在页面初始化时，本身是从数据库中导出按时间排序的最近的50条数据，但由于返回的数据为object格式，Json无法解析全部内容。

解决方案：

在进行提取数据时，减少数据的量。
example：本身是提50条数据，现改为提30条。
