HTTP请求

1. get请求

package main

import (
    "fmt"
    "io/ioutil"
    "net/http"
    "os"
)

func main() {

    resp, err := http.Get("https://baike.baidu.com/item/书/130176?fr=aladdin")
    HandleError(err, "http.Get")

    defer resp.Body.Close()

    bytes, e := ioutil.ReadAll(resp.Body)
    HandleError(e, "outil.ReadAll")

    fmt.Println("get:", string(bytes))

}

func HandleError(err error, when string) {
    if err != nil {
        fmt.Println(err, "net.Listen")
        os.Exit(1)

    }
}

2. post请求

package main

import (
    "fmt"
    "io/ioutil"
    "net/http"
    "os"
    "strings"
)

func main() {

    url := "https://httpbin.org/post?name=love"
    //携带的数据类型,表单
    resp, err := http.Post(url, "application/x-www-form-urlencoded", strings.NewReader("rmb=0.5&hobby=love"))
    HandleError(err, "htp.post")
    defer resp.Body.Close()

    bytes, e := ioutil.ReadAll(resp.Body)
    HandleError(e, "ioutil.ReadAll")
    fmt.Println(string(bytes))

}

func HandleError(err error, when string) {
    if err != nil {
        fmt.Println(err, "net.Listen")
        os.Exit(1)

    }
}

3. 搭建http服务端

package main

import (
    "net/http"
    "strconv"
)

func main() {

    //路由规则1
    http.HandleFunc("/shit", func(writer http.ResponseWriter, request *http.Request) {
        writer.Write([]byte("im ok!"))
    })

    //路由规则2
    http.HandleFunc("/hello", func(writer http.ResponseWriter, request *http.Request) {
        writer.Write([]byte("请求的方法=" + request.Method))
        writer.Write([]byte("请求的内容长度=" + strconv.Itoa(int(request.ContentLength))))
        writer.Write([]byte("请求的主机=" + request.Host))
        writer.Write([]byte("请求的协议=" + request.Proto))
        writer.Write([]byte("请求的远程地址=" + request.RemoteAddr))
        writer.Write([]byte("请求的路由=" + request.RequestURI))
        writer.Write([]byte("朕已收到信息"))

    })

    //监听
    http.ListenAndServe("0.0.0.0:8080", nil)
}

end
