有没有更简单的方法来提取/解析未修复的嵌套对象值？

Question

我试图使用Zapier的代码从webhook的结果中解析特定的嵌套对象（Sign_UP_Appointment）

Webhook结果

{
"entity":{
    "OPPORTUNITY_ID":24096201,
    "OPPORTUNITY_NAME":"Scott Williams ",
    "OPPORTUNITY_STATE":"OPEN",
    "RESPONSIBLE_USER_ID":1737942,
    "OWNER_USER_ID":1737942,
    "DATE_CREATED_UTC":"2019-04-15T17:02:11.567",
    "DATE_UPDATED_UTC":"2019-04-15T17:02:40.437",
    "VISIBLE_TO":"OWNER",
    "CUSTOMFIELDS":[
        {
            "CUSTOM_FIELD_ID":"Administration_Type__c",
            "FIELD_VALUE":"Summary Administration"
        },
        {
            "CUSTOM_FIELD_ID":"Initial_Appointment__c",
            "FIELD_VALUE":"2019-04-11T20:45:00"
        },
        {
            "CUSTOM_FIELD_ID":"Sign_Up_Appointment__c",
            "FIELD_VALUE":"2019-04-18T21:00:00"
        }
    ],
    "TAGS":[],
    "LINKS":[
        {
            "LINK_ID":205236388,
            "CONTACT_ID":287320999,
            "OPPORTUNITY_ID":24096201
        }
    ]
}
}

我想只返回自定义字段（Sign_Up_Appointment__c）。我尝试了下面的代码，但问题是关于订单更改的后续结果。有没有办法过滤掉Sign_Up_Appointment__c对象？

const result = JSON.parse(inputData.body);
return {result: result, SignUpDate: result.entity.CUSTOMFIELDS[3]};

大卫来自Zapier平台团队。

是的！你可以使用Array.find：

const result = JSON.parse(inputData.body);
return {
  result,
  SignUpDate: result.entity.CUSTOMFIELDS.find(
    f => f.CUSTOM_FIELD_ID === "Sign_Up_Appointment__c"
  )
};

SignUpDate将是undefined，如果阵列中没有field_id的字段（我不确定这有多大可能）
