未从 HTTP Get 方法获得响应

Question

在 go 中实现了从给定 URL 获取信息的逻辑，问题是 net/http 的响应为空。

package main

import (

    "fmt"

    "io/ioutil"

    "net/http"

)

func main() {

    resp, err := http.Get("https://azure.microsoft.com/en-us/")

    if err != nil {

        // handle error

    }

    body, err := ioutil.ReadAll(resp.Body)

    bodyString := string(body)

    fmt.Print(bodyString)

    fmt.Printf("%v %v", body, err)

}

输出：它返回空切片而不是返回 HTML 内容

[]byte{} <nil>

我正在使用 Go 版本 1.14.3。

当您设置 User-Agent 标头时，这似乎有效：package mainimport (&nbsp; &nbsp; "fmt"&nbsp; &nbsp; "io/ioutil"&nbsp; &nbsp; "net/http")func main() {&nbsp; &nbsp; client := &http.Client{}&nbsp; &nbsp; req, err := http.NewRequest("GET", "https://azure.microsoft.com/en-us/", nil)&nbsp; &nbsp; req.Header.Add("User-Agent", "Mozilla")&nbsp; &nbsp; resp, err := client.Do(req)&nbsp; &nbsp; if err != nil {&nbsp; &nbsp; &nbsp; &nbsp; fmt.Println(err)&nbsp; &nbsp; }&nbsp; &nbsp; body, err := ioutil.ReadAll(resp.Body)&nbsp; &nbsp; bodyString := string(body)&nbsp; &nbsp; fmt.Print(bodyString)}
