工作中，经常会遇到事件通知，目前用比较多的是钉钉，群自定义机器人可以让我们快速实现消息通知。

包

package dingtalk
​
import (
    "bytes"
    "encoding/json"
    "errors"
    "io/ioutil"
    "net/http"
    "strconv"
    "time"
)
​
// SendMessage 发送钉钉机器人消息
func SendMessage(url, message string, ats ...string) (respContent string, err error) {
    c := &http.Client{
        Timeout: time.Second * 30,
    }
    data := map[string]interface{}{
        "msgtype": "text",
        "text":    map[string]string{"content": message},
    }
    if len(ats) != 0 {
        isAtAll := false
        atMobiles := []string{}
        for i := range ats {
            if ats[i] == "all" {
                isAtAll = true
            } else {
                atMobiles = Append(atMobiles, ats[i])
            }
        }
        data["at"] = map[string]interface{}{
            "isAtAll":   isAtAll,
            "atMobiles": atMobiles,
        }
    }
    b, _ := json.Marshal(data)
    resp, err := c.Post(url, "application/json", bytes.NewReader(b))
    if err != nil {
        return "post请求失败", err
    }
    defer resp.Body.Close()
    body, _ := ioutil.ReadAll(resp.Body)
    if resp.StatusCode == 200 {
        return string(body), nil
    }
    return string(body), errors.New(strconv.Itoa(resp.StatusCode))
}

测试

package main
​
import (
    "fmt"
    "dingtalk"
)
​
func main() {
    result, err := dingtalk.SendMessage("https://oapi.dingtalk.com/robot/send?access_token=XXXXXX", "测试消息通知", "all")
    if err != nil {
        fmt.Println("发送失败", result)
        return
    }
    fmt.Println("发送成功", result)
}
