抓取数千个 URL 在 power 查询中获得 "Please specify how to connect"

Question

这是我的函数代码。我有另一个 table 和我所有的 URL。但是当我尝试将我的 URL 插入 CarData 时，它 returns Please specify how to connect 并向我展示了这个 window。我不想为数千个 URL 手动执行的操作。它为什么要求这个以及我如何为我的数千个 URL 自动执行它？

(CarData as text)=>
let
    Source = Web.BrowserContents(CarData),
    #"Extracted Table From Html" = Html.Table(Source, {{"Column1", ".key"}, {"Column2", ".value"}}, [RowSelector=".key"]),
    #"Changed Type" = Table.TransformColumnTypes(#"Extracted Table From Html",{{"Column1", type text}, {"Column2", type text}}),
    #"Transposed Table" = Table.Transpose(#"Changed Type"),
    #"Promoted Headers" = Table.PromoteHeaders(#"Transposed Table", [PromoteAllScalars=true]),
    #"Split Column by Delimiter" = Table.SplitColumn(#"Promoted Headers", "Gas Mileage", Splitter.SplitTextByDelimiter("/", QuoteStyle.Csv), {"Gas Mileage.1", "Gas Mileage.2"}),
    #"Changed Type2" = Table.TransformColumnTypes(#"Split Column by Delimiter",{{"Gas Mileage.1", type text}, {"Gas Mileage.2", type text}}),
    #"Replaced Value" = Table.ReplaceValue(#"Changed Type2","Transmission:","",Replacer.ReplaceText,{"Transmission"}),
    #"Split Column by Delimiter1" = Table.SplitColumn(#"Replaced Value", "SAE Net Torque @ RPM", Splitter.SplitTextByDelimiter("@", QuoteStyle.Csv), {"SAE Net Torque @ RPM.1", "SAE Net Torque @ RPM.2"}),
    #"Changed Type3" = Table.TransformColumnTypes(#"Split Column by Delimiter1",{{"SAE Net Torque @ RPM.1", Int64.Type}, {"SAE Net Torque @ RPM.2", Int64.Type}}),
    #"Renamed Columns" = Table.RenameColumns(#"Changed Type3",{{"SAE Net Torque @ RPM.1", "SAE Net Torque"}, {"SAE Net Torque @ RPM.2", "SAE Torque RPM"}}),
    #"Split Column by Delimiter2" = Table.SplitColumn(#"Renamed Columns", "SAE Net Horsepower @ RPM", Splitter.SplitTextByDelimiter("@", QuoteStyle.Csv), {"SAE Net Horsepower @ RPM.1", "SAE Net Horsepower @ RPM.2"}),
    #"Changed Type4" = Table.TransformColumnTypes(#"Split Column by Delimiter2",{{"SAE Net Horsepower @ RPM.1", Int64.Type}, {"SAE Net Horsepower @ RPM.2", Int64.Type}}),
    #"Renamed Columns1" = Table.RenameColumns(#"Changed Type4",{{"SAE Net Horsepower @ RPM.1", "SAE Net Horsepower"}, {"SAE Net Horsepower @ RPM.2", "SAE Net Horsepower RPM"}, {"Displacement", "Displacement (L)"}}),
    #"Split Column by Delimiter3" = Table.SplitColumn(#"Renamed Columns1", "Displacement (L)", Splitter.SplitTextByDelimiter("/", QuoteStyle.Csv), {"Displacement (L).1", "Displacement (L).2"}),
    #"Changed Type5" = Table.TransformColumnTypes(#"Split Column by Delimiter3",{{"Displacement (L).1", type text}, {"Displacement (L).2", Int64.Type}}),
    #"Renamed Columns2" = Table.RenameColumns(#"Changed Type5",{{"Displacement (L).2", "Displacement"}}),
    #"Changed Type6" = Table.TransformColumnTypes(#"Renamed Columns2",{{"Displacement", Int64.Type}}),
    #"Replaced Value1" = Table.ReplaceValue(#"Changed Type6","L","",Replacer.ReplaceText,{"Displacement (L).1"}),
    #"Changed Type7" = Table.TransformColumnTypes(#"Replaced Value1",{{"Displacement (L).1", type number}}),
    #"Renamed Columns3" = Table.RenameColumns(#"Changed Type7",{{"Gas Mileage.1", "mpg city"}, {"Gas Mileage.2", "mpg Hwy"}}),
    #"Replaced Value2" = Table.ReplaceValue(#"Renamed Columns3","mpg Hwy","",Replacer.ReplaceText,{"mpg Hwy"}),
    #"Replaced Value3" = Table.ReplaceValue(#"Replaced Value2","mpg City","",Replacer.ReplaceText,{"mpg city"}),
    #"Changed Type8" = Table.TransformColumnTypes(#"Replaced Value3",{{"mpg city", Int64.Type}, {"mpg Hwy", Int64.Type}})
in
    #"Changed Type8"

如果您需要，这是我的 URL 的代码；

let
  Source = Binary.Decompress(File.Contents("path\trims.xml.gz"), Compression.GZip),
    #"Imported CSV" = Xml.Document(Source),
    Value = #"Imported CSV"{0}[Value],
    #"Removed Columns" = Table.RemoveColumns(Value,{"Attributes"}),
    #"Removed Other Columns" = Table.SelectColumns(#"Removed Columns",{"Value"}),
    #"Expanded Value" = Table.ExpandTableColumn(#"Removed Other Columns", "Value", {"Name", "Namespace", "Value", "Attributes"}, {"Name", "Namespace", "Value.1", "Attributes"}),
    #"Removed Other Columns1" = Table.SelectColumns(#"Expanded Value",{"Value.1"}),
    #"Renamed Columns" = Table.RenameColumns(#"Removed Other Columns1",{{"Value.1", "URLs"}}),
    #"Changed Type" = Table.TransformColumnTypes(#"Renamed Columns",{{"URLs", type text}}),
    #"Invoked Custom Function" = Table.AddColumn(#"Changed Type", "Data", each #"Table 3"([URLs]))
in
    #"Invoked Custom Function"

尝试这个解决方案，它不准确，但它是一个类似的错误；
