NodeJs脚本发送告警示例

需要安装依赖 urllib：

  1. yarn add urllib
  3. # 或者
  4. npm install urllib --save

脚本示例如下，请根据自身情况修改使用：

  1. var md5 = require('crypto').createHash('md5')
  2. var urllib = require('urllib');
  4. var taskid = 189; // 告警任务ID
  5. var token = 'xxxxxx'; // 告警任务token
  6. var [timestamp, sign] = gen_sign(taskid, token)
  7. var options = {
  8.   method: 'POST',
  9.   dataType: 'json',
  10.   headers: {
  11.     'Content-Type': 'application/json'
  12.   },
  13.   content: JSON.stringify({
  14.     taskid: 189,
  15.     timestamp: timestamp,
  16.     sign: sign,
  17.     ctn: {
  18.       say: 'hello world'
  19.     }
  20.   })
  21. }
  22. urllib.request('https://alarm-dog-service.domain.com/alarm/report', options, function (err, data, res) {
  23.   if (err) {
  24.     throw err; // you need to handle error
  25.   }
  26.   console.log(res.statusCode);
  27.   console.log(res.headers);
  28.   // data is Buffer instance
  29.   console.log(data);
  30. });
  32. /**
  33.  * 生成签名
  34.  * @param {Number} taskid 
  35.  * @param {String} token 
  36.  */
  37. function gen_sign(taskid, token)
  38. {
  39.   var timestamp = parseInt(Date.now() / 1000)
  41.   var str = `${taskid}&${timestamp}${token}`
  42.   var sign = md5.update(str).digest('hex')
  44.   return [timestamp, sign]
  45. }

将脚本保存为 alarm.js，然后执行 node alarm.js，可能输出以下示例：

  1. 200
  2. {
  3.   server: 'Tengine',
  4.   'content-type': 'application/json; charset=utf-8',
  5.   'content-length': '117',

  23.   },
  24.   msg: 'success',
