how did you manage to solve this? I am trying to obtain the cookies from a query to the server, cookies that will later serve me to make a request to the login

I've done similar work using the R data connection and httr library.


A sample of my code:

    bodyString = "'{""user_name"":"""&Text.From(UserName)&""",""password"":"""&Text.From(Password)&"""}'",
    Source = R.Execute("library(httr)#(lf)library(jsonlite)#(lf)getToken <- POST("""", add_headers(""Content-Type""=""application/json""), body = "&bodyString&")#(lf)tokenIs <- cookies(getToken)#(lf)getData <- GET("",0"", add_headers(""Content-Type""=""application/json""), set_cookies(""name""=tokenIs$name,""value""=tokenIs$value))#(lf)result <- data.frame(content(getData, ""text""))"),
    result1 = Table.ToRecords(Source{[Name="result"]}[Value]),
    #"Converted to Table" = Table.FromList(result1, Splitter.SplitByNothing(), null, null, ExtraValues.Error),
    Column1 = #"Converted to Table"{0}[Column1],
    stuff = Json.Document(Column1[#"content.getData...text.."]),
    #"Converted to Table1" = Table.FromList(stuff, Splitter.SplitByNothing(), null, null, ExtraValues.Error),
    #"Expanded Column1" = Table.ExpandRecordColumn.....
