(AutoIt) Facebook Upload Photo from Local File

Uploads a new photo with a caption from a local file.

Chilkat ActiveX Downloads ActiveX for 32-bit and 64-bit Windows

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

$oHttp = ObjCreate("Chilkat.Http")

$oReq = ObjCreate("Chilkat.HttpRequest")
$oReq.HttpVerb = "POST"
$oReq.ContentType = "multipart/form-data"
$oReq.Path = "/v2.7/me/photos"

; Use the previously obtained access token.
; Note: The publish_actions scope is required to upload a photo.
$oReq.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.
$oReq.AddHeader "Expect","100-continue"

; Set a photo caption.
$oReq.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.
Local $bSuccess = $oReq.AddFileForUpload("source","qa_data/jpg/penguins2.jpg")
If ($bSuccess <> True) Then
    ConsoleWrite($oReq.LastErrorText & @CRLF)
    Exit
EndIf

; Upload the image file..
Local $oResp = $oHttp.SynchronousRequest("graph.facebook.com",443,True,$oReq)
If ($oHttp.LastMethodSuccess <> True) Then
    ConsoleWrite($oHttp.LastErrorText & @CRLF)
    Exit
EndIf

; Examine the response body:
Local $sResponseJson = $oResp.BodyStr
ConsoleWrite($sResponseJson & @CRLF)

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