      },
      {
        "X-Forwarded-Proto": "https"
      },
      {
        "Connection": "close"
      },
      {

      },
      {

        "X-PD-Event-Received": "1572013154"
      }
    ],
    "body": ""
  }
}

需要对上述数据进行分析，使其如下所示：

description: "Interface is down for a viptela router"
cmdb_ci: "myrtr1"
Error URL: https://GINC.netspyglass.com/emb_graph.html?update=true&networkId=1&intervalHr=24&width=500&height=300&vars=ifOperStatus.9853.2

我尝试了以下几点：

var body = PD.inputRequest.rawBody;
var cef_event = {
  event_type: PD.Trigger,
  description: body.details.payload.summary,
  cmdb_ci: body.details.payload.cmdb_ci,
  event_action: PD.Trigger,
  details: body.details
}

我得到以下错误：

错误执行转换: TypeError:无法读取未定义

的属性“有效载荷”

Answer 1

看起来，JSON的rawBody成员是一个字符串，而不是一个对象，因此您需要执行如下操作：

var body = JSON.parse(PD.inputRequest.rawBody);

在你进入它的成员之前。

目前，您只是将字符串本身分配给body。

此外，一旦解析完，JSON对象中与有效载荷相关的键实际上不是子对象，键实际上是字符串，如payload.summary，因此要访问这些字符串，您应该这样做：

body.details['payload.summary']

综合起来，您提供的代码应该更像这样(虽然它没有提供您列出的输出，但我认为您提供的代码之外还有更多的代码)：

var body = JSON.parse(PD.inputRequest.rawBody);
var cef_event = {
  event_type: PD.Trigger,
  description: body.details['payload.summary'],
  cmdb_ci: body.details['payload.cmdb_ci'],
  event_action: PD.Trigger,
  details: body.details
}
