我尝试从 Go net/http 转换为 Go Fiber，如何进行转换？

Question

我是 golang 的新手，然后我学习了，我喜欢 Go 纤维。我从 Go Fiber 中学习，我看到 net/http 示例非常酷。然后我尝试将 Go net/http 示例转换为 Go 光纤。下面是上网/httppackage mainimport (    "embed"    "io/fs"    "log"    "net/http"    "runtime/pprof")//go:embed nextjs/dist//go:embed nextjs/dist/_next//go:embed nextjs/dist/_next/static/chunks/pages/*.js//go:embed nextjs/dist/_next/static/*/*.jsvar nextFS embed.FSfunc main() {    // Root at the `dist` folder generated by the Next.js app.    distFS, err := fs.Sub(nextFS, "nextjs/dist")    if err != nil {        log.Fatal(err)    }    // The static Next.js app will be served under `/`.    http.Handle("/", http.FileServer(http.FS(distFS)))    // The API will be served under `/api`.    http.HandleFunc("/api", handleAPI)    // Start HTTP server at :8080.    log.Println("Starting HTTP server at http://localhost:8080 ...")    log.Fatal(http.ListenAndServe(":8080", nil))}func handleAPI(w http.ResponseWriter, _ *http.Request) {    // Gather memory allocations profile.    profile := pprof.Lookup("allocs")    // Write profile (human readable, via debug: 1) to HTTP response.    err := profile.WriteTo(w, 1)    if err != nil {        log.Printf("Error: Failed to write allocs profile: %v", err)    }}

Answer 1

我认为你可以替换这个：

  app.Get("/api", func(c *fiber.Ctx) error {

    profile := pprof.Lookup("allocs")

    return c.Get(profile)

  })

有了这个：

  app.Get("/api", func(c *fiber.Ctx) error {

    profile := pprof.Lookup("allocs")

    return profile.WriteTo(c, 1)

  })

*fiber.Ctximplements io.Writer，因此您应该能够像http.ResponseWriter在这种情况下一样使用它。
