抱歉,我是 Power BI 新手。我正在使用 Power BI 调用 Azure API,该 API 将列出我的订阅中的所有虚拟机,但它只会显示下一个链接之前的前 50 个虚拟机。
这是我正在调用的 API;
https://management.azure.com/subscriptions/< subscription >/providers/Microsoft.Compute/virtualMachines?api-version=2017-12-01
我见过其他页面和论坛也有类似问题(例如 Microsoft API ),但没有针对 Azure API。我搞乱了他们的修复,但无法弄清楚如何将其应用到我的修复中。
他们的代码;
let
GetUserInfo = (Path)=>
let
Source = Json.Document(Web.Contents(Path)),
LL= @Source[value],
result = try @LL & @GetUserInfo(Source[#"@odata.nextLink"]) otherwise @LL
in
result,
Fullset = GetUserInfo("https://graph.microsoft.com/beta/users?$select=manager&$expand=manager"),
#"Converted to Table" = Table.FromList(Fullset, Splitter.SplitByNothing(), null, null, ExtraValues.Error),
#"Expanded Column1" = Table.ExpandRecordColumn(#"Converted to Table", "Column1", {"id", "displayName", "manager"}, {"Column1.id", "Column1.displayName", "Column1.manager"}),
#"Expanded Column1.manager" = Table.ExpandRecordColumn(#"Expanded Column1", "Column1.manager", {"id", "displayName"}, {"id", "displayName"}),
#"Renamed Columns" = Table.RenameColumns(#"Expanded Column1.manager",{{"Column1.displayName", "Employee Full Name"}, {"Column1.id", "Employee Id"}, {"id", "Manager Id"}, {"displayName", "Manager Full name"}})
in
#"Renamed Columns"
与我通过简单的网络链接连接源后的开始相比;
let
Source = Json.Document(Web.Contents("https://management.azure.com/subscriptions/< subscription >/providers/Microsoft.Compute/virtualMachines?api-version=2017-12-01")),
#"Converted to Table" = Record.ToTable(Source)
in
#"Converted to Table"
如果我要调整它,我怀疑它会看起来像这样;
let
GetUserInfo = (Path)=>
let
Source = Json.Document(Web.Contents(Path)),
LL= @Source[value],
result = try @LL & @GetUserInfo(Source[#"@odata.nextLink"]) otherwise @LL
in
result,
Fullset = GetUserInfo("https://management.azure.com/subscriptions/< subscription >/providers/Microsoft.Compute/virtualMachines?api-version=2017-12-01"),
#"Converted to Table" = Record.ToTable(Source)
in
#"Converted to Table"
但是单击“确定”后,系统提示我出现以下错误;
Expression.Error: The name 'Source' wasn't recognized. Make sure it's spelled correctly.
对此的任何帮助将不胜感激。

对于任何感兴趣的人,这就是我通过此链接最终所做的事情:
https://datachant.com/2016/06/27/cursor-based-pagination-power-query/
let
iterations = 10,
url =
"https://management.azure.com/subscriptions/< subscription >/providers/Microsoft.Compute/virtualMachines?api-version=2017-12-01",
FnGetOnePage =
(url) as record =>
let
Source = Json.Document(Web.Contents(url)),
data = try Source[value] otherwise null,
next = try Source[nextLink] otherwise null,
res = [Data=data, Next=next]
in
res,
GeneratedList =
List.Generate(
()=>[i=0, res = FnGetOnePage(url)],
each [i]<iterations and [res][Data]<>null,
each [i=[i]+1, res = FnGetOnePage([res][Next])],
each [res][Data])
in
GeneratedList
一整天的谷歌搜索头痛:S
