效果:

实现代码main.go

package mainimport ("encoding/json""fmt""io/ioutil""net/http""os"
)type AreaData struct {Continent string `json:"continent"`Country   string `json:"country"`ZipCode   string `json:"zipcode"`Owner     string `json:"owner"`Isp       string `json:"isp"`Adcode    string `json:"adcode"`Prov      string `json:"prov"`City      string `json:"city"`District  string `json:"district"`
}type IpData struct {Code string   `json:"code"`Data AreaData `json:"data"`Ip   string   `json:"ip"`
}func main() {var args = os.Argsif len(args) > 1 {for index, val := range args {if index > 0 {fmt.Printf("parsms[%d]: %s\n", index, val)}}} else {fmt.Println("no args ip address to check exp: ./checkip 14.23.36.151")return}//ip := "14.23.36.151"url := fmt.Sprintf("https://qifu-api.baidubce.com/ip/geo/v1/district?ip=%s", args[1])resp, err := http.Get(url)if err != nil {fmt.Printf("Error making request: %v\n", err)return}defer resp.Body.Close()body, err := ioutil.ReadAll(resp.Body)if err != nil {fmt.Printf("Error reading response body: %v\n", err)return}var ipInfo IpDataerr = json.Unmarshal(body, &ipInfo)if err != nil {fmt.Printf("Error parsing JSON: %v\n", err)return}fmt.Printf("Code: %s\n", ipInfo.Code)fmt.Printf("Ip: %s\n", ipInfo.Ip)fmt.Printf("Continent: %s\n", ipInfo.Data.Continent)fmt.Printf("Country: %s\n", ipInfo.Data.Country)fmt.Printf("ZipCode: %s\n", ipInfo.Data.ZipCode)fmt.Printf("Owner: %s\n", ipInfo.Data.Owner)fmt.Printf("Isp: %s\n", ipInfo.Data.Isp)fmt.Printf("Adcode: %s\n", ipInfo.Data.Adcode)fmt.Printf("Prov: %s\n", ipInfo.Data.Prov)fmt.Printf("City: %s\n", ipInfo.Data.City)fmt.Printf("District: %s\n", ipInfo.Data.District)
