二、测试告警与恢复通知

1. 模拟“告警触发”（Firing）命令

这条命令会模拟发送一条严重（critical）的 CPU 告警。

curl -X POST -H "Content-Type: application/json" -d @- http://localhost:8060/dingtalk/webhook1/send <<'EOF'
{
  "version": "4",
  "status": "resolved",
  "receiver": "webhook1",
  "groupLabels": {
    "alertname": "HighMemoryUsage"
  },
  "commonLabels": {
    "alertname": "HighMemoryUsage",
    "severity": "warning"
  },
  "commonAnnotations": {},
  "externalURL": "http://localhost:9093",
  "alerts": [
    {
      "status": "resolved",
      "labels": {
        "alertname": "HighMemoryUsage",
        "severity": "warning",
        "instance": "192.168.1.100:9100"
      },
      "annotations": {
        "summary": "内存使用率过高",
        "description": "服务器 192.168.1.100 的内存使用率已恢复正常，当前值 60%。"
      },
      "startsAt": "2026-11-04T09:00:00Z",
      "endsAt": "2026-11-04T10:15:00Z",
      "generatorURL": "http://localhost:9090/graph",
      "fingerprint": "test-resolved-01"
    }
  ]
}
EOF

2. 模拟“告警恢复”（Resolved）命令

这条命令会模拟发送一条警告（warning）级别的恢复通知。

curl -X POST -H "Content-Type: application/json" -d @- http://localhost:8060/dingtalk/webhook1/send <<'EOF'
{
  "version": "4",
  "status": "resolved",
  "receiver": "webhook1",
  "groupLabels": {
    "alertname": "HighMemoryUsage"
  },
  "commonLabels": {
    "alertname": "HighMemoryUsage",
    "severity": "warning"
  },
  "commonAnnotations": {},
  "externalURL": "http://localhost:9093",
  "alerts": [
    {
      "status": "resolved",
      "labels": {
        "alertname": "HighMemoryUsage",
        "severity": "warning",
        "instance": "192.168.1.100:9100"
      },
      "annotations": {
        "summary": "内存使用率过高",
        "description": "服务器 192.168.1.100 的内存使用率已恢复正常，当前值 60%。"
      },
      "startsAt": "2026-11-04T09:00:00Z",
      "endsAt": "2026-11-04T10:15:00Z",
      "generatorURL": "http://localhost:9090/graph",
      "fingerprint": "test-resolved-01"
    }
  ]
}
EOF
