如何刷新在 Power BI 服务上使用自定义函数的报表？

Question

我知道这个问题之前已经发布过很多次，但我无法找到 solid/working 解决方案。

我正在尝试找出一种解决方法，通过 Power BI 服务使用自定义函数刷新数据集。我的查询如下所示：

let
    Clients = Json.Document(Web.Contents("https://api.createsend.com/api/v3.2/clients.json")),
    #"Converted to Table" = Table.FromList(Clients, Splitter.SplitByNothing(), null, null, ExtraValues.Error),
    #"Expanded Column1" = Table.ExpandRecordColumn(#"Converted to Table", "Column1", {"ClientID", "Name"}, {"ClientID", "Name"}),

    GetDetails = (ClientID as text) => 
    let 
        Source = Json.Document(Web.Contents("https://api.createsend.com/api/v3.2/clients/" & ClientID & "/campaigns.json"))
    in 
        Source,
    Output = Table.AddColumn(#"Expanded Column1", "Details", each GetDetails([ClientID])),
    #"Expanded Details" = Table.ExpandListColumn(Output, "Details"),
    #"Expanded Details1" = Table.ExpandRecordColumn(#"Expanded Details", "Details", {"Name", "FromName", "FromEmail", "ReplyTo", "SentDate", "TotalRecipients", "CampaignID", "Subject", "WebVersionURL", "WebVersionTextURL"}, {"Details.Name", "Details.FromName", "Details.FromEmail", "Details.ReplyTo", "Details.SentDate", "Details.TotalRecipients", "Details.CampaignID", "Details.Subject", "Details.WebVersionURL", "Details.WebVersionTextURL"})
in 
    #"Expanded Details1"

这在 Power BI 桌面上运行良好。但是，我在 Power BI 服务上收到以下错误：

Answer 1

我成功了。通过一些研究，我们发现实际问题不是函数而是动态 API 路径本身。 Power BI 在刷新服务报表之前验证静态数据源路径。

我通过替换解决了问题：

Source = Json.Document(Web.Contents("https://api.createsend.com/api/v3.2/clients/" & ClientID & "/campaigns.json"))

有了这个：

Json.Document(Web.Contents("https://api.createsend.com/", [RelativePath="api/v3.2/clients/" & ClientID & "/campaigns.json", Headers=[#"Authorization"="My API Authorization token"]]))
