NodeJs脚本发送告警示例

需要安装依赖 urllib：

yarn add urllib

# 或者
npm install urllib --save

脚本示例如下，请根据自身情况修改使用：

var md5 = require('crypto').createHash('md5')
var urllib = require('urllib');

var taskid = 189; // 告警任务ID
var token = 'xxxxxx'; // 告警任务token
var [timestamp, sign] = gen_sign(taskid, token)
var options = {
  method: 'POST',
  dataType: 'json',
  headers: {
    'Content-Type': 'application/json'
  },
  content: JSON.stringify({
    taskid: 189,
    timestamp: timestamp,
    sign: sign,
    ctn: {
      say: 'hello world'
    }
  })
}
urllib.request('https://alarm-dog-service.domain.com/alarm/report', options, function (err, data, res) {
  if (err) {
    throw err; // you need to handle error
  }
  console.log(res.statusCode);
  console.log(res.headers);
  // data is Buffer instance
  console.log(data);
});

/**
 * 生成签名
 * @param {Number} taskid 
 * @param {String} token 
 */
function gen_sign(taskid, token)
{
  var timestamp = parseInt(Date.now() / 1000)

  var str = `${taskid}&${timestamp}${token}`
  var sign = md5.update(str).digest('hex')
  
  return [timestamp, sign]
}

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