go语言的net/http包的使用非常的简单优雅
(1)服务端
package main import ( "flag" "fmt" "net/http" ) func main() { host := flag.String("host", "127.0.0.1", "listen host") port := flag.String("port", "80", "listen port") http.HandleFunc("/hello", Hello) err := http.ListenAndServe(*host+":"+*port, nil) if err != nil { panic(err) } } func Hello(w http.ResponseWriter, req *http.Request) { <p> w.Write([]byte("Hello World"))</p>}
http.HandleFunc用来注册路径处理函数,会根据给定路径的不同,调用不同的函数
http.ListenAndSercer监听iP与端口,本机IP可以省略不写,仅书写冒号加端口,如http.ListenAndSercer(“:8080”, nil)
路径处理函数,参数必须为w http.ResponseWriter和 req *http.Request且不能有返回值
测试结果:成功
(2)客户端
package main import ( "fmt" "io/ioutil" "net/http" ) func main() { response, _ := http.Get("http://localhost:80/hello") defer response.Body.Close() body, _ := ioutil.ReadAll(response.Body) fmt.Println(string(body)) }
测试结果:成功
