Question:
I’m using iwr to make a request like so:
|
1 2 |
iwr "http://someapi/param" -UseBasicParsing -Method Head |
This gets me the headers which looks something like this:
|
1 2 3 4 5 6 7 8 |
$var1 = "Timing-Allow-Origin: * X-CID: 1 Accept-Ranges: bytes Content-Length: 43 Cache-Control: public,max-age=172800 Content-Type: image/gif Other headers |
How do I check if the headers contain this:
|
1 2 3 |
"Timing-Allow-Origin"="*" "Cache-Control"="public,max-age=172800" |
I tried
|
1 2 3 |
$var2.RawContent = iwr "http://someapi/param" -UseBasicParsing -Method Head Write-Host ($var2.RawContent -like "*Timing-Allow-Origin: *") |
But this returns false for some reason. Is there a way to do this?
Answer:
Headers returned from Invoke-Webrequest is a IDictionary.
You can test by retrieving the value of the key you need.

1 2 3 4 5 6 7 |
$response = iwr "http://someapi/param" -UseBasicParsing -Method Head if ($response.Headers["Cache-Control"] -eq "public,max-age=172800") { Write-Output "Found" } else { Write-Output "Not found" } |
