我为 Order Object 创建了一个触发器，并且只希望从该对象中提取特定字段以创建自定义 JSON 数据结构。我尝试将对象中需要的字段保存到局部变量中，将它们放入列表中，然后对其进行序列化，但输出错误。缺少大括号，并且未在正确位置添加逗号。请在下面参考我的代码。

trigger ActiveOrder on Order (after insert, after update) 
{


    private String ordAccountId;
    private String ordBillingStreet;
    private String ordBillingCity;
    private String ordBillingState;
    private String ordBillingPostalCode;
    private String ordBillingCountry;
    private String ordDescription;
    private Double ordTotalAmount;
    private String ordOrderNumber;
    private String ordShipToContact;
    private String ordShipToMethod;
    private String ordShippingStreet;
    private String ordShippingCity;
    private String ordShippingState;
    private String ordShippingPostalCode;
    private String ordShippingCountry;
    private String ordBillToAttn;
    private String ordCustomerPO;
    private String ordShipToAttn;


    for(Order o : Trigger.New)
    {

        If(o.Status == 'Activated')
        {

            ordAccountId = o.AccountId;
            ordBillingStreet = o.BillingStreet;
            ordBillingCity = o.BillingCity;
            ordBillingState = o.BillingState;
            ordBillingPostalCode = o.BillingPostalCode;
            ordBillingCountry = o.BillingCountry;
            ordDescription = o.Description;
            ordTotalAmount = o.TotalAmount;
            ordOrderNumber = o.OrderNumber;
            ordShipToContact = o.Ship_To_Name__c;
            ordShippingStreet = o.ShippingStreet;
            ordShippingCity = o.ShippingCity;
            ordShippingState = o.ShippingState;
            ordShippingPostalCode = o.ShippingPostalCode;
            ordShippingCountry = o.ShippingCountry;
            ordBillToAttn = o.BillToAttn__c;
            ordCustomerPO = o.Customer_PO__c;
            ordShipToAttn = o.Ship_to_Attention__c;


            List<String> ordInvoice = new List<String>();


            ordInvoice.add('Account Id: ' + ordAccountId + ', ' 
                           + 'Billing Street: ' + ordBillingStreet + ', ' 
                           + 'Billing City: ' + ordBillingCity + ', ' 
                           + 'Billing State: ' + ordBillingState + ', ' 
                           + 'Billing Postal Code: ' + ordBillingPostalCode + ', ' 
                           + 'Billing Country: ' + ordBillingCountry + ', ' 
                           + 'Description: ' + ordDescription + ', ' 
                           + 'Total Amount: ' + ordTotalAmount + ', ' 
                           + 'Order Number: ' + ordOrderNumber + ', ' 
                           + 'Ship To Contact: ' + ordShipToContact + ', ' 
                           + 'Shippin Street: ' + ordShippingStreet + ', ' 
                           + 'Shipping City: ' + ordShippingCity + ', ' 
                           + 'Shipping State: ' + ordShippingState + ', ' 
                           + 'Shipping Postal Code: ' + ordShippingPostalCode + ', ' 
                           + 'Shipping Country: ' + ordShippingCountry + ', ' 
                           + 'Bill To Attn: ' + ordBillToAttn + ', ' 
                           + 'Customer PO: ' + ordCustomerPO + ', ' 
                           + 'Ship To Attn: ' + ordShipToAttn);

            System.debug('Pre JSON: ' + ordInvoice);


            String ordInvoiceJSON = JSON.serialize(ordInvoice);

            System.debug('Post JSON: ' + ordInvoice);
            System.debug('Post JSON: ' + ordInvoicePostJSON);


        }
    }
}

您正在用一个值序列化一个列表，这是一个长字符串，其中包含您的所有数据您几乎自己序列化了订单。在您的情况下，您应该尝试使用 Map 来构建您的对象，然后对其进行序列化。例如

Map<String,String> orderMap = new Map<String,String>();

orderMap.put('Account Id', o.accountId);
orderMap.put('Billing Street',o.billingStreet);
//...etc
String jsonStr = JSON.serialize(orderMap);
System.debug(jsonStr);

尝试一下，或者如果您只想要所有具有值的字段和更少的代码，您可以使用方法sObject.getPopulatedFieldsAsMap()。这可能很简单JSON.serialize(o.getPopulatedFieldsAsMap());

希望有帮助
