为什么在PowerShell中用椭圆修剪我的REST输出？

Question

I am using Invoke-RestMethod to manage a Websense server. When I use the following curl command to list categories from a terminal my results are as expected:

curl -k -u <username>:<password> -X GET https://<ipaddress>:<port>/api/web/v1/categories/all

The output I receive is:

I am trying to take this content and save it into a variable so I can output it to a file (preferably a CSV). When I attempt to run the command as a variable or when I output the content to a text file my response is trimmed for some reason with an ellipses at the end of the text string. How do I get the content to output to the file the same as it appears on screen? Using fl gives slightly more data and using ft -auto has no effect at all.

Invoke-RestMethod -Uri $uriListCat -Method Get -Headers $headers |
    Out-File u:\debug.txt

Invoke-RestMethod returns the result as a PowerShell object data structure. Convert it to JSON before writing it to a file if you want the output in JSON format:

Invoke-RestMethod ... |
    ConvertTo-Json -Depth 10 |
    Out-File ...

If you want the result as a CSV expand the Categories property and export the resulting list as a CSV:

Invoke-RestMethod ... |
    Select-Object -Expand Categories |
    Export-Csv 'C:\categories.csv' -NoType
