ETag

ETag middleware for Fiber that lets caches be more efficient and save bandwidth, as a web server does not need to resend a full response if the content has not changed.

​ ETag 中间件，用于 Fiber，它让缓存更高效并节省带宽，因为如果内容没有改变，Web 服务器不需要重新发送完整响应。

// Or extend your config for customization

Config 配置

Property 属性Type 输入Description 说明Default 默认
Weak 弱boolWeak indicates that a weak validator is used. Weak etags are easy to generate but are less useful for comparisons. 弱表示使用的是弱验证器。弱 etag 易于生成，但对于比较而言不太有用。false
Next 下一步func(*fiber.Ctx) boolNext defines a function to skip this middleware when returned true. 接下来定义一个函数，在返回 true 时跳过此中间件。nil
