（Salesforce.com REST API）如何确定哪些产品与Opportunity关联？

我正在使用Salesforce.com REST API。我需要确定哪些产品Product2与Opportunity关联。到目前为止，我还无法接通

在SalesOfce UI中，Opportunity可以与价格手册和产品相关联。价格手册包含产品，但也可以将产品与商机直接关联起来

通过API查询opportunity会产生以下结果：

从中可以看出没有Product2数据可用。然而，有一个Pricebook2Id。有人可能会假设，查询特定的价格手册会产生与之相关的产品信息。但是，查询特定的价格手册会产生以下结果：

如何使用Salesforce.com REST API确定哪些产品与Opportunity关联？

有一个名为“Opportunity Product”的对象。您还需要获得该对象，并将适当的机会与产品联系起来。 这是一种多对多的关系，而不是一对多的关系，因此每个机会都可能涉及多个产品，反之亦然
