前端如何实现“无感刷新”Token？90% 的人都做错了

The grid-template-areas CSS property specifies named grid areas, establishing the cells in the grid and assigning them names.

前端无痛刷新Token 这个需求场景很常见，几乎很多项目都会用上，之前项目也实现过，最近刚好有个项目要实现，重新梳理一番。 对于需要前端实现无痛刷新Token，无非就两种： 请求前判断Token是否过期，过期则刷新 请求后根据返回状态判断是否过期，过期则刷新 处理逻辑 实现起来也没多大差别，只是判断

Cross-Origin Resource Sharing (CORS) is a standard that allows a server to relax the same-origin policy. This is used to explicitly allow some cross-origin requests while rejecting others. For example, if a site offers an embeddable service, it may be necessary to relax certain restrictions. Setting up such a CORS configuration isn't necessarily easy and may present some challenges. In these pages, we'll look into some common CORS error messages and how to resolve them.

The content CSS property replaces content with a generated value. It can be used to define what is rendered inside an element or pseudo-element. For elements, the content property specifies whether the element renders normally (normal or none) or is replaced with an image (and associated "alt" text). For pseudo-elements and margin boxes, content defines the content as images, text, both, or none, which determines whether the element renders at all.

判断Token是否过期 没过期则正常处理 过期则发起刷新Token的请求 拿到新token保存，把刷新Token后重新发送请求的响应数据返回到对应的调用者 重新发送Token过期这段时间内发起的请求，保持Token过期这段时间发起请求状态（不能进入失败回调） 前端实现阻塞请求结果 通过返回一个pen

The attr() CSS function is used to retrieve the value of an attribute of the selected element and use it in a property value, similar to how the var() function substitutes a custom property value. It can also be used with pseudo-elements, in which case the attribute's value on the pseudo-element's originating element is returned.
