我正在使用webapi来获取数据。API 将结果限制为 100。在本例中，有 2481 个，但由于此限制，如果不使用 OData 函数，我无法获取所需的所有记录。我被告知要使用跳过功能，但有关此的文档对于以前没有使用过它的人来说不是很有帮助。
我的电话如下：

我需要执行以下操作：返回特定字段("已创建"(包含当前年份的所有记录，即使结果超过 100 个也是如此。我假设需要使用$search和跳过函数，但我不确定语法。
谢谢 史蒂文
根据此处的文档，您应该将跳过参数合并到 URL 中。
像这样：
https://accounting.sageone.co.za/api/2.0.0/TaxInvoice/get?apikey={xxxxxxxxxx}&companyid=12345&includeDetail=true&$skip=100&$orderby=Created%20desc
提供的示例是：
https://services.odata.org/OData/OData.svc/Products?$skip=2&$top=2&$orderby=Rating
您可能需要摆弄一下，但这似乎是方法。
要返回特定字段("已创建"(包含当前年份的所有记录，您需要将以下筛选条件附加到 url。您可以在此处查看支持的其他 OData Date 函数。
&$filter=year(Created) eq 2018
OData 处理可能返回大量数据的服务的分页。由于 API 限制为 100，表示数据的页面大小，因此每次服务调用最多可以获得 100 条记录。要获取从 101 到 200 的记录，您需要通过将$skip=100附加到 url 来跳过前 100 条。此外，如果您需要获取从 201 到 300 的记录，则将 $skip=200 附加到 url，依此类推，直到获得 2481 条记录。这意味着您需要通过增加$skip值来调用服务 25 次。
因此，使用额外的过滤器和跳过查询，您需要将以下查询字符串附加到现有 url
&$filter=year(Created) eq 2018&$skip=100
此外，如果要获取每个服务调用少于 100 条的记录，则需要使用$top查询。假设应用程序中的页面大小为 50，则将$top=50追加到查询字符串。
