Add-Type -Path "C:\chilkat\ChilkatDotNet47-x64\ChilkatDotNet47.dll"

#  This example assumes Chilkat HTTP to have been previously unlocked.
#  See Global Unlock Sample for sample code.

$http = New-Object Chilkat.Http

$req = New-Object Chilkat.HttpRequest
$req.HttpVerb = "POST"
$req.ContentType = "multipart/form-data"
$req.Path = "/v2.7/me/photos"

#  Use the previously obtained access token.
#  Note: The publish_actions scope is required to upload a photo.
$req.AddHeader("Authorization","Bearer FACEBOOK-ACCESS-TOKEN")

#  Send an "Expect: 100-continue" header in the request.
#  This causes the HTTP server to end a 100-continue response
#  immediately after receiving the HTTP header.  The client
#  (Chilkat) will receive this intermediate response, and if
#  it's not an error response, it knows that the HTTP server will
#  accept the data that is forthcoming.
#  The alternative is to get an error response after trying to upload
#  the entire contents of the files.
$req.AddHeader("Expect","100-continue")

#  Set a photo caption.
$req.AddParam("caption","Here are some penguins!")

#  Additional parameters can be added to the request by 
#  calling AddParam once per parameter.  
#  See https://developers.facebook.com/docs/graph-api/reference/user/photos
#  for more information about other optional parameters.

#  Indicate the local file to be uploaded.
$success = $req.AddFileForUpload("source","qa_data/jpg/penguins2.jpg")

}

#  Examine the response body:
$responseJson = $resp.BodyStr
$($responseJson)

#  The response contains JSON, such as this:
#  {"id":"10210224963435862","post_id":"10224048320139890_10210224963435862"}
