Help with photos module and http post?

inzel

Hello Everyone,

I am currently messing around with the Kairos API and am trying to use Pythonista to take a new photo on my iPad and then upload that photo to the Kairos enroll API. I am able to get this to work fine with a URL image but for the life of me I am unable to get this to work by taking a photo with the photos module. From my understanding the photos module returns a PIL Image and I think I need to base64 encode that before uploading to the Kairos API??

Here is my code without using the photos module:

#import photos
import requests

#img = photos.capture_image()
url = "https://api.kairos.com/enroll"

values = """
  {
    "image": "URL for image",
    "subject_id": "test",
    "gallery_name": "test"
  }
"""

headers = {
    'Content-Type': 'application/json',
    'app_id': '********',
    'app_key': '************************'
}

request = requests.post(url, data=values, headers=headers)
response = request.content

print(response)

Im hoping that someone can help me out by showing me what I need to do to be able to accomplish this task. Any help is greatly appreciated.

Thank you in advance,

Colin

fwiw, requests lets you use req.json() rather than json.loads(req.contents). also, you can use json=values instead of json.dumps(values) in the request.

@inzel this is great. I am learning to use Kairos as well and I will try this out!

Thanks!

I just came back to this project and I get an error!

r = requests.post(url, data=json.dumps(values), headers = headers)

Object of type 'bytes' is not JSON serializable

I havent made any changes so I cant imagine why this is suddenly happening.

Any thoughts?

@Vincekok Thank you!

Have you switched to py3 interpreter from py2, or vice versa?

inzel

Hey JonB!

Yes I have done that. Its really odd as this was working. Could it be because I went to the iPadOS beta?

inzel

I tested itg on my phone and am getting the same results. No idea what changed here

JonB

print(values)

The original code would have probably worked in py2. In py3, you’d need to do

image.decode('ascii')

As the argument to json.dumps.

I dont quite understand. Can you please explain the change to me?

Edit: It does work making that change but I dont understand why its now needed. Thats what Im interested in learning about
