解决方案 #

问题根源 #

项目同时存在Fiber v2（业务代码使用的正确版本）和Fiber v1（间接引入的旧版本），v1.14.6版本的Fiber依赖的github.com/gofiber/utils版本与当前v1.1.0不兼容，GetTrimmedParam函数在该utils版本中不存在，导致编译失败。

修复步骤 #

1. 移除Fiber v1的间接依赖

   go get github.com/gofiber/fiber@none
   

2. 清理Go模块缓存

   go clean -modcache
   

3. 重新整理依赖

   go mod tidy
   

4. 确认项目导入
   检查所有代码文件，确保导入的Fiber包都是github.com/gofiber/fiber/v2，没有引用v1版本的github.com/gofiber/fiber。

执行完以上步骤后重新编译项目，即可解决编译报错，之后再测试/api/user接口的访问问题。
