最近迷上了golang，开始进行相关语言的测试。下面是一个126短地址API调用的例子。
https://github.com/forrestsun/Sample2Go/blob/master/126short/main.go
package main
import (
"encoding/json"
"flag"
"fmt"
"io/ioutil"
"net/http"
"net/url"
"os"
"strings"
)
const (
API_Key = "" //私有KEY
)
type ShortResult struct {
Status_code int `json:"status_code"` //状态编码
Longurl string `json:"longUrl"` //长地址
Status_txt string `json:"status_txt"` //状态信息
Url string `json:"url"` //短地址
}
func Shorten(uri string) (string, int, error) {
u := "http://126.am/api!shorten.action?key=" + API_Key + "&longUrl=" + url.QueryEscape(uri)
response, err := http.Get(u)
if err != nil {
return "", 0, err
}
body, err := ioutil.ReadAll(response.Body)
defer response.Body.Close()
str_body := string(body)
str_body = strings.Replace(str_body, "\", "", -1)
var shortUri ShortResult
err = json.Unmarshal([]byte(str_body), &shortUri)
if err != nil {
return "err address", 0, err
}
return shortUri.Url, shortUri.Status_code, nil
}
func main() {
flag.Parse()
if flag.NArg() < 1 {
fmt.Fprintln(os.Stderr, "请输入原始地址！")
return
}
uri, code, err := Shorten(flag.Arg(0))
if err != nil {
fmt.Fprintln(os.Stderr, err)
os.Exit(-1)
}
//可以通过code进一步显示详细信息
fmt.Println("反馈状态编码为：", code)
fmt.Println("短地址：", uri)
return
}
