Question

我需要创建一个POST请求，该请求需要另一个POST请求。

因此，有两个不同的POST请求，无法单独执行。我将如何合并这两个请求？

作为参考，我需要发布到Exact Online。他们有一个REST API documentation应该可以使事情变得简单。在我的示例中，我想创建一个新的采购订单，找到here。有两个必填属性：“ Supplier”和“ PurchaseOrderLines”。供应商很容易陈述，但是采购订单行是用a second POST request创建的。

例如，对PurchaseOrderLines的POST请求例如如下：

POST(url = paste("https://start.exactonline.nl/api/v1/", division, "/purchaseorder/PurchaseOrderLines", sep = ""),
     add_headers(Key = "authorization", Authorization = paste("Bearer", accessToken, sep = " ")),
     body = list(Item = "ItemCode", PurchaseOrderId = "999999", QuantityInPurchaseUnits = "1.0"),
     encode = "json")

到目前为止，对于实际的PurchaseOrder请求，我有以下信息：

POST(url = paste("https://start.exactonline.nl/api/v1/", division, "/purchaseorder/PurchaseOrders", sep = ""),
     add_headers(Key = "authorization", Authorization = paste("Bearer", accessToken, sep = " ")),
     body = list(Supplier = "SupplierName", PurchaseOrderID = "999999"), encode = "json")

如文档中所述：“采购订单行不能单独过帐。它们应该是PurchaseOrder过帐的一部分。”

所以问题是：如何使采购订单行成为PurchaseOrder Post的一部分。

Answer 1

通常，在“精确在线”上，您可以使用OData批处理合并多个请求。仅当流量到达一个端点（URL）时，此方法才有效。

但是，您的问题本质上更具实用性。确切地要求每笔交易至少要有一行（我知道这很愚蠢，但可以接受）。这适用于用户界面以及反映此业务规则的API。

在PurchaseOrder创建事件中，您需要将行作为消息的一部分发送出去。

请选中https://start.exactonline.nl/docs/HlpRestAPIResourcesDetails.aspx?name=PurchaseOrderPurchaseOrders，然后在文本中搜索“收藏夹”。

需要插入至少1行。

如果语法不正确，请在Invantive SQL中使用insert into exactonlinerest..purchaseorders ... identified by ...，然后运行它。在select * from sessionios@datadictionary中，您会找到实际的呼叫。启用本机跟踪时，您可以在调试跟踪视图中看到发送到Exact Online的有效负载。

作为一个旁注，对于上传数据，我通常更喜欢使用XML API。它更快，更聪明。

启动dbgview。使用INVANTIVE_TRACE_ACTIVE = true环境变量启用跟踪日志记录。启动主动控制或其他SQL产品。运行以下代码以在新订单中创建每个销售订单的副本：

set trace-native-calls true

begin transaction

insert into exactonlinerest..salesorders
( description
, orderedby
, deliverto
, deliveryaddress
, invoiceto
)
select 'EDI order '
       || ' van '
       || to_char(sysdate, 'DD-MM-YYYY')
       description
,      sor.orderedby
       label 'Ordered by account ID'
,      sor.deliverto
       label 'Deliver to account ID'
,      sor.deliveryaddress
       label 'Deliver to address ID'
,      sor.invoiceto
       label 'Invoice to account ID'
from   ( select orderid, orderedby, invoiceto, deliverto, deliveryaddress  from exactonlinerest..salesorders ) sor
identified
by     sor.orderid

insert into exactonlinerest..salesorderlines
( description
, item
, quantity
, unitcode
)
select sle.description
,      sle.item
,      sle.quantity
,      sle.unitcode
from   exactonlinerest..salesorderlines sle
attach
to     sle.orderid
