Title: Go language application cases and code examples in well-known enterprises

In recent years, with the rapid development of the Internet industry, more and more enterprises have begun to use Go language for development. As a powerful and flexible programming language, Go language is widely used in large enterprises and well-known technology companies. This article will introduce some cases of using Go language in well-known enterprises and give specific code examples.

1. Google (Google): Google is one of the founding companies of Go language. Since the advent of Go language, Google has adopted Go language extensively for internal development. For example, Google's container orchestration system Kubernetes is developed using the Go language. The following is a simple Go language example to implement a simple HTTP server:

package main

import (
    "fmt"
    "net/http"
)

func handler(w http.ResponseWriter, r *http.Request) {
    fmt.Fprintf(w, "Hello, World!")
}

func main() {
    http.HandleFunc("/", handler)
    http.ListenAndServe(":8080", nil)
}

2. Apple (Apple): Apple has also begun to use the Go language in some projects. For example, Apple started using Go language in its camera and photo applications to improve performance and maintainability. The following is a code example that uses the Go language to call the iOS system API:

package main

import (
    "fmt"
    "github.com/goki/fyne"
)

func main() {
    app := fyne.NewApp()
    window := app.NewWindow("Hello")
    window.SetContent(fyne.NewLabel("Hello, World!"))
    window.ShowAndRun()
}

3. Facebook: Facebook is one of the largest social networks in the world and has also begun to use the Go language in some projects. For example, one of Facebook's internal tools was developed into a Go language version to improve development efficiency and reduce resource overhead. The following is a simple Go language code example to implement a simple RESTful API service:

package main

import (
    "fmt"
    "log"
    "net/http"
)

func handler(w http.ResponseWriter, r *http.Request) {
    w.WriteHeader(http.StatusOK)
    fmt.Fprintf(w, "Hello, World!")
}

func main() {
    http.HandleFunc("/api/hello", handler)
    log.Fatal(http.ListenAndServe(":8080", nil))
}

The above are some cases of Go language application in well-known enterprises and specific code examples. With the continued popularity and application of Go language in enterprises, I believe that more and more companies will choose Go language for development in the future to cope with growing business needs.
