问题
I'm trying to create a new Ad Creative for an event ad (Post-Migration), using the field image_file.
Via the Graph API Explorer I send the following post request:
URL: https://graph.facebook.com//act_xxxx/adcreatives
object_id: xxxxx
body: body here
title: title here
name: name here
image_file: @C:\Art.jpg
I get the following exception response:
"The Adcreative Create Failed for the following reason: Invalid image file: The image_file field does not specify a POST file name."
Apparently I'm not using the image_file parameter right. How should I use it?
回答1:
Try uploading image only, and than use image hash to upload creative.
Parameters:
[
IMAGE_NAME => '@' + path
]
POST https://graph.facebook.com//act_xxxx/adimages
IMAGE_NAME is name with extension - image.jpg, or image.png...
As the response, you will get
[
'images' => [
[
'hash' => ...,
'url' => ....
]
]
]
Than use the image hash you received and create ad creative with that.
If you want to do only one request, do next:
curl \
-F 'access_token=...' \
-F 'title=Test title' \
-F 'body=Test body' \
-F 'link_url=http://www.whatever.com' \
-F 'name=test creative' \
-F 'image_file=Art.jpg' \
-F 'Art.jpg=@C:\Art.jpg ' \
'https://graph.facebook.com/act_xxxx/adcreatives'
