Data in the Payload area, automatically formatted with timestamps
在“JSON”模式下,鼠标光标定位在秒级时间戳、毫秒级时间戳,则出现时间值格式化(YYYY/MM/DD HH:mm:ss)之后的浮窗。In JSON mode, if the mouse cursor is positioned at a second level timestamp or a millisecond level timestamp, a floating window will appear after formatting the time value (YYYY/MM/DD HH: mm: ss).
在“TABLE”模式下,鼠标悬停在秒级时间戳、毫秒级时间戳,则出现时间值格式化(YYYY/MM/DD HH:mm:ss)之后的浮窗。In "TABLE" mode, hovering over second level timestamps and millisecond level timestamps will result in a floating window after formatting the time value (YYYY/MM/DD HH: mm: ss).

新增字段允许数据类型: int,float,string,json string等数据格式。若新增出现重名key, 后值覆盖前值。New fields allow data types such as int, float, string, json string, and other data formats. If a duplicate key is added, the last value will overwrite the previous value.
备注1:关于字段 nbf, exp, iat 时间表示格式,请在此处详细查看。支持秒时间戳格式,点这里生成秒级时间戳NOTE1: Regarding the time representation format of fields nbf, exp, and iat, please see here in detail. Support second timestamp format, Click here to generate second timestamp.
备注2:对于“aud”字段,多个URL使用逗号分隔。NOTE2: For the 'aud' field, separate multiple URLs with commas.

jwt_decoder.html 独立一个全新的JWT页面有何有意义?
What is the significance of creating a completely new JWT page
JWT解码器 / JWT Decoder
主域名默认指向JWT解码页面。也就是说,网站首页,就是JWT解码页面。因为首页会定期更新内容或新增板块,为了避免页面在各大浏览器端,可能出现未知问题,导致JWT解码功能异常。所以单独创建了一个JWT解码页面,该页面结构简单,各端浏览器兼容性强。The main domain name defaults to the JWT decoding page. That is to say, the homepage of the website is the JWT decoding page. Because the homepage will regularly update content or add new sections, in order to avoid unknown issues that may occur on major browsers, resulting in abnormal JWT decoding function. So a separate JWT decoding page was created, which has a simple structure and strong compatibility with various browsers.
