GO语言基础之net/http
内置包net/http。
// 服务端
package main import ( "fmt" "net/http" ) // http server func sayHello(w http.ResponseWriter, r *http.Request) { fmt.Fprintln(w, "Hello World!") } func main() { http.HandleFunc("/", sayHello) err := http.ListenAndServe(":8080", nil) if err != nil { fmt.Printf("http server failed, err:%v\n", err) return } }
编译启动之后浏览器输入:127.0.0.1:8080
// 客户端 package main import ( "fmt" "io/ioutil" "net/http" ) func main() { resp, err := http.Get("http://127.0.0.1:8080/") if err != nil { fmt.Println("get failed, err:", err) return } defer resp.Body.Close() body, err := ioutil.ReadAll(resp.Body) if err != nil { fmt.Println("read from resp.Body failed,err:", err) return } fmt.Print(string(body)) }
