HTTP Post with ContentURL - api

Question

I a using Microsoft Bot Framework and am trying to do a HTTP Post with an image sent to the bot as an attachment. I see a ContentURL in the Attachment object but cannot figure out how to POST the image to my API with RestSharp?
Any Ideas?

Answer 1

There are a couple possibilities here.
First is to send an image as an attachment. Please see this documentation you JSON would look like this:
{
"type": "message",
"from": {
"id": "12345678",
"name": "sender's name"
},
"conversation": {
"id": "abcd1234",
"name": "conversation's name"
},
"recipient": {
"id": "1234abcd",
"name": "recipient's name"
},
"text": "Here's a picture of the duck I was telling you about.",
"attachments": [
{
"contentType": "image/png",
"contentUrl": "http://aka.ms/Fo983c",
"name": "duck-on-a-rock.jpg"
}
],
"replyToId": "5d5cdc723
}
the other possibility is that you could send an image in a card (which has 2 possibilities itself). For this you can see this documentation for rich cards. in this here is an example of the JSON for that
{
"type": "message",
"from": {
"id": "12345678",
"name": "sender's name"
},
"conversation": {
"id": "abcd1234",
"name": "conversation's name"
},
"recipient": {
"id": "1234abcd",
"name": "recipient's name"
},
"attachments": [
{
"contentType": "application/vnd.microsoft.card.hero",
"content": {
"title": "title goes here",
"subtitle": "subtitle goes here",
"text": "descriptive text goes here",
"images": [
{
"url": "http://aka.ms/Fo983c",
"alt": "picture of a duck",
"tap": {
"type": "playAudio",
"value": "url to an audio track of a duck call goes here"
}
}
],
"buttons": [
{
"type": "playAudio",
"title": "Duck Call",
"value": "url to an audio track of a duck call goes here"
},
{
"type": "openUrl",
"title": "Watch Video",
"image": "http://aka.ms/Fo983c",
"value": "url goes here of the duck in flight"
}
]
}
}
],
"replyToId": "5d5cdc723"
}
the second option for cards would be adaptive cards. by using the visualizer you can actually manipulate the JSON and see how it would be rendered in different channels.
