使用 Power BI (PowerQuery) 获取 Azure 零售价格 Rest API

Question

在上图中我们有 Items 和 NextPageLink。数据存在于 Items 和 NextPageLink 中，包含下一页数据的 links。

我正在尝试使用具有多个页面的 Json 响应来自动执行 rest-API 调用。这个想法是自动调用 NextPageLink 直到没有 NextPageLink。我想将数据放入单个 table.

这是我用来提取数据的 link：https://prices.azure.com/api/retail/prices

这是最后一页 link：https://prices.azure.com/api/retail/prices?$skip=408500

请帮帮我

Answer 1

创建函数ReadSingle

(offset) => 
let Source =Json.Document(Web.Contents(" https://prices.azure.com/api/retail/prices?$skip="& Number.ToText( offset )))[Items]
in Source

使用循环读入数据。你可以重复直到完成，但坦率地说我的电脑锁住了，所以我正在做第 0-25 页，按 100's

let Source

= List.Generate(  
 ()  =>  [ Offset = 0, Data = ReadSingle(0) ],
 each [Offset] <= 2500, 
 each [ Data = ReadSingle( [Offset] ),
        Offset =  [Offset] + 100 ], 
 each [Data]
 ),

z=Table.FromColumns(Source),
#"Added Index" = Table.AddIndexColumn(z, "Index", 0, 1, Int64.Type),
#"Unpivoted Other Columns" = Table.UnpivotOtherColumns(#"Added Index", {"Index"}, "Attribute", "Value"),
#"Removed Columns" = Table.RemoveColumns(#"Unpivoted Other Columns",{"Index", "Attribute"}),
#"Expanded Value" = Table.ExpandRecordColumn(#"Removed Columns", "Value", {"currencyCode", "tierMinimumUnits", "retailPrice", "unitPrice",     "armRegionName", "location", "effectiveStartDate", "meterId", "meterName", "productId", "skuId", "productName", "skuName", "serviceName", "serviceId",     "serviceFamily", "unitOfMeasure", "type", "isPrimaryMeterRegion", "armSkuName"}, {"currencyCode", "tierMinimumUnits", "retailPrice", "unitPrice",     "armRegionName", "location", "effectiveStartDate", "meterId", "meterName", "productId", "skuId", "productName", "skuName", "serviceName", "serviceId",     "serviceFamily", "unitOfMeasure", "type", "isPrimaryMeterRegion", "armSkuName"})
in #"Expanded Value"

如果您愿意，可以交换以重复循环，直到 NextPageLink 为空。请参阅我最喜欢的参考资料 use List.Generate to make API Calls in Power Query M
