You can test the uploadSet CAP backend part using these http calls:
### Create file
# @name file
POST http://localhost:4004/v2/admin/Files
Authorization: Basic admin:
Content-Type: application/json
{
"mediaType": "image/png",
"fileName": "picture.png",
"size": 1000
}
### Fill Variable from Response
@ID = {{file.response.body.$.d.ID}}
### Upload Binary PNG content
PUT http://localhost:4004/v2/admin/Files({{ID}})/content
Authorization: Basic admin:
Content-Type: image/png
< ./picture.png
### Get uploaded png
GET http://localhost:4004/v2/admin/Files({{ID}})/content
Authorization: Basic admin:
The picture.png file must be in the same folder as the http test file.
