curl 'http://127.0.0.1:8999/webhook'  -H 'Content-Type: application/json'    -d '
  {
    "receiver": "webhook-test",
    "status": "firing",
    "alerts": [
      {
        "status": "firing",
        "labels": {
          "alertname": "test alert1",
          "instance": "example1",
          "severity": "critical"
        },
        "annotations": {
          "info": "Test message,ignore",
          "description": "This is test summary,ignore",
          "summary": "This is test message,ignore"
        },
        "startsAt": "2019-07-24T02:38:30.763785079Z",
        "endsAt": "0001-01-01T00:00:00Z",
        "generatorURL": "critical"
      }
    ],
    "groupLabels": {
      "alertname": "test alert1"
    },
    "commonLabels": {
      "alertname": "test alert1",
      "instance": "example1"
    },

    "version": "4",
    "groupKey": "{}/{alertname=~\"^(?:test.*)$\"}:{alertname=\"test alert1\"}"
  }'

2、使用指定微信机器人发送消息

curl 'http://127.0.0.1:8999/webhook?key=xxxxxx-xxxxx-xxxxx-xxxxxx-xxxxxxx'  -H 'Content-Type: application/json'    -d '
  {
    "receiver": "webhook-test",

    "alerts": [
      {
        "status": "firing",
        "labels": {
          "alertname": "test alert1",
          "instance": "example1",

        "endsAt": "0001-01-01T00:00:00Z",
        "generatorURL": "critical"
      }
    ],
    "groupLabels": {
      "alertname": "test alert1"
    },
    "commonLabels": {
      "alertname": "test alert1",
      "instance": "example1"

    "version": "4",
    "groupKey": "{}/{alertname=~\"^(?:test.*)$\"}:{alertname=\"test alert1\"}"
  }'

3、使用alert内容指定微信机器人发送消息

  curl 'http://127.0.0.1:8999/webhook'  -H 'Content-Type: application/json'    -d '
  {
    "receiver": "webhook-test",
    "status": "firing",
    "alerts": [
      {
        "status": "firing",
        "labels": {
          "alertname": "test alert1",
          "instance": "example1",
          "severity": "critical"
        },
        "annotations": {
          "info": "Test message,ignore",
          "description": "This is test summary,ignore",
          "summary": "This is test message,ignore"
        },
        "startsAt": "2019-07-24T02:38:30.763785079Z",
        "endsAt": "0001-01-01T00:00:00Z",
        "generatorURL": "critical"
      }
    ],
    "groupLabels": {
      "alertname": "test alert1"
    },
    "commonLabels": {
      "alertname": "test alert1",
      "instance": "example1"
    },
    "commonAnnotations": {
      "info": "Test message,ignore",
      "summary": "This is test summary,ignore",
      "wechatRobot": "https://qyapi.weixin.qq.com/cgi-bin/webhook/send?key=xxxxxx-xxxxx-xxxxx-xxxxxx-xxxxxxx"
    },
    "externalURL": "http://localhost:9093",

    "groupKey": "{}/{alertname=~\"^(?:test.*)$\"}:{alertname=\"test alert1\"}"
  }'
