Invoke-WebRequest, POST with parameters
Put your parameters in a hash table and pass them like this:
$postParams = @{username='me';moredata='qwerty'}Invoke-WebRequest -Uri http://example.com/foobar -Method POST -Body $postParams
For some picky web services, the request needs to have the content type set to JSON and the body to be a JSON string. For example:
Invoke-WebRequest -UseBasicParsing http://example.com/service -ContentType "application/json" -Method POST -Body "{ 'ItemID':3661515, 'Name':'test'}"or the equivalent for XML, etc.
This just works:
$body = @{ "UserSessionId"="12345678" "OptionalEmail"="MyEmail@gmail.com"} | ConvertTo-Json$header = @{ "Accept"="application/json" "connectapitoken"="97fe6ab5b1a640909551e36a071ce9ed" "Content-Type"="application/json"} Invoke-RestMethod -Uri "http://MyServer/WSVistaWebClient/RESTService.svc/member/search" -Method 'Post' -Body $body -Headers $header | ConvertTo-HTML
