    },

如果看到的话，日期字段不会反序列化.它给出了数字而不是日期格式.

If you see, the date fields are not deserialized. It gives a number instead of date format.

如何以适当的日期格式获取JSON响应?

How to get the JSON response in the appropriated date format?

我正在尝试使用

I am trying to use this URL in my Java code to get JSON response as String and it's working. But I want to parse it to an object. I have to create class for items, and badge_counts with fields required in it. The date fields must be date not integers. While parsing to object from string response, there may be parsing exception. So how can I resolve that?

推荐答案

从马口中说:"Stack Exchange API中的所有日期均以Unix纪元时间表示，这是自1970年1月1日UTC午夜以来的秒数. Stack Exchange API不接受或返回小数时间，所有内容都应四舍五入到最接近的整数秒."显然，这可以轻松转换为内部使用的任何日期格式.

From the horse's mouth: "All dates in the Stack Exchange API are in unix epoch time, which is the number of seconds since midnight UTC January 1st, 1970. The Stack Exchange API does not accept or return fractional times, everything should be rounded to the nearest whole second." Obviously that can easily converted in whatever date format you are using internally.
