How to use Rotating proxy through GO?

Please note before configuration: Go needs to be executed in non-mainland network environment for IPFoxy proxy to take effect

1. IPFoxy page operation

After purchasing a rotating proxy, go to the [Rotating Residential Proxy] page and complete the following operations:

1. Protocol type: http

2. Format: Username: Password@Host:Port

3. Generate Proxy

4. Copy the generated connection information

2. Operation in Go

1. Copy the following code into the Go code, and paste the proxy connection information just copied from IPFoxy into the code. For example, the proxy connection information is: username:password@gate-us-ipfoxy.io:58688

package main

    import (
      "fmt"
      "io/ioutil"
      "log"
      "net/http"
      "os"
    )
    func main() {
      os.Setenv("HTTP_PROXY", "http://username:password@gate-us-ipfoxy.io:58688")
      resp, err := http.Get("https://lumtest.com/myip.json")
      fmt.Println(resp)
      
      if err != nil {
        panic(err)
      }
      defer resp.Body.Close()

      if resp.StatusCode == http.StatusOK {
        bodyBytes, err := ioutil.ReadAll(resp.Body)
        if err != nil {
          log.Fatal(err)
        }
        bodyString := string(bodyBytes)
        fmt.Println(bodyString)
      }
    }
