动态生成json文件

Question

我需要使用JSON文件做一个post request。JSON当前看起来像这样:

{
"compositeRequest" : [{
// Account
"method" : "POST",
"url" : "/services/data/v52.0/sobjects/Account",
"referenceId" : "refAccount",
"body" : { 
"Name" : req.body.accName 
}
},{
// Contact
"method" : "POST",
"url" : "/services/data/v52.0/sobjects/Contact",
"referenceId" : "refContact",
"body" : { 
"LastName" : req.body.conLastName,
"AccountId" : "@{refAccount.id}"
}
},{
// Order
"method" : "POST",
"url" : "/services/data/v52.0/sobjects/Order",
"referenceId" : "refOrder",
"body" : { 
"AccountId" : "@{refAccount.id}",
"Pricebook2Id" : PBResult.records[0].Id,
"EffectiveDate" : date,
"Status" : "Draft"
}
},{
// OrderItem
"method" : "POST",
"url" : "/services/data/v52.0/sobjects/OrderItem",
"referenceId" : "refOrderItem",
"body" : { 
"Product2Id" : req.params.productId,
"OrderId" : "@{refOrder.id}",
"Quantity" : req.body.itemQuantity,
"PricebookEntryId" : entryResult.records[0].Id,
"UnitPrice" : entryResult.records[0].UnitPrice,
"blng__BillableUnitPrice__c": entryResult.records[0].UnitPrice,
"SBQQ__ChargeType__c": prodResult.records[0].SBQQ__ChargeType__c,
"blng__TaxRule__c": prodResult.records[0].blng__TaxRule__c,
"blng__BillingRule__c": prodResult.records[0].blng__BillingRule__c,
"blng__RevenueRecognitionRule__c": prodResult.records[0].blng__RevenueRecognitionRule__c,
"ServiceDate": date,
"blng__LastChargeToDate__c": date
}
}
]
}

我想根据数组的大小生成更多的OrderItem对象(在注释中指出)，我该怎么做呢?我已经有了需要添加到主体上的数据。是否有可能创建一个函数来创建另一个OrderItem，并将其放在已经存在的OrderItem之后(如果我打算从零开始创建第一个OrderItem会更好)。

提前感谢。

Answer 1

如果你想添加一些东西到object，你必须使用

Object.assign(myObject, data);

如果你想添加一些东西到array，你必须使用:

myArray.push(data);

由于我不是很理解你的数据结构，我只是尝试参考你标记的// OrderItem。在本例中，它类似于:

let newOrderItem = {
// OrderItem
"method" : "POST",
"url" : "/services/data/v52.0/sobjects/OrderItem",
"referenceId" : "refOrderItem",
"body" : { 
"Product2Id" : req.params.productId,
"OrderId" : "@{refOrder.id}",
"Quantity" : req.body.itemQuantity,
"PricebookEntryId" : entryResult.records[0].Id,
"UnitPrice" : entryResult.records[0].UnitPrice,
"blng__BillableUnitPrice__c": entryResult.records[0].UnitPrice,
"SBQQ__ChargeType__c": prodResult.records[0].SBQQ__ChargeType__c,
"blng__TaxRule__c": prodResult.records[0].blng__TaxRule__c,
"blng__BillingRule__c": prodResult.records[0].blng__BillingRule__c,
"blng__RevenueRecognitionRule__c": prodResult.records[0].blng__RevenueRecognitionRule__c,
"ServiceDate": date,
"blng__LastChargeToDate__c": date
}
yourObject.compositeRequest.push(newOrderItem)
