Config 配置

Property 属性Type 输入Description 说明Default 默认
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
Header 标题stringHeader is the header key where to get/set the unique request ID. Header 是获取/设置唯一请求 ID 的标头键。“X-Request-ID”
Generator 生成器func() stringGenerator defines a function to generate the unique identifier. 生成器定义一个生成唯一标识符的函数。utils.UUID
ContextKeyinterface{}ContextKey defines the key used when storing the request ID in the locals for a specific request. ContextKey 定义在本地存储特定请求的请求 ID 时使用的键。“requestid”

Default Config 默认配置

The default config uses a fast UUID generator which will expose the number of requests made to the server. To conceal this value for better privacy, use the utils.UUIDv4 generator.

​ 默认配置使用一个快速的 UUID 生成器，它将公开发送到服务器的请求数。为了更好地保护隐私而隐藏此值，请使用 utils.UUIDv4 生成器。
