如何读取 Power Query -> Web.Contents 响应 header？

Question

let
    url = "http://XXXX/Account/Login",
    body = "{""UserName"": ""test""}",
    Source = Json.Document(Web.Contents(url,[          
     Headers = [#"Content-Type"="application/json"],
     Content = Text.ToBinary(body) 
    ]))
in
    Source

如何从 Source 读取 Header 值？

Answer 1

无法获得响应 headers。您可能只会得到请求 headers 和一些附加信息。使用Value.Metadata函数

let
    md = Value.Metadata(Web.Contents("https://www.google.com", [Headers=[qwer="asdf"], Query=[q="test"], IsRetry=true]))
in
    md
