Python and pushbullet api: send a file

Question

I'm trying to send a file using Pushbullet following their API docs. This is my function:

def push_file(AccessToken, file_name):
    f = open(file_name, 'rb')
    file_type = mimetypes.guess_type(file_name)[0]

    print("Uploading {0}...".format(file_name))
    try:
        data = {
            'file_name': file_name, 
            'file_type' : file_type
        }

        resp = requests.post(UPLOAD_REQUEST_URL, data=data, auth=(AccessToken, '')).json()
        if resp.get('error') != None:
            print("Error: {0}".format(resp.get('error')['message']))
            return

        file_url = resp.get('file_url')
        print(file_url)
        resp = requests.post(resp.get('upload_url'), data=resp.get('data'), auth=(AccessToken, ''), files={'file': f})

        data = { 
            'type' : 'file', 
            'file_name' : file_name, 
            'file_type' : file_type, 
            'file_url' : file_url, 
            'body' : ''
        }
        resp = requests.post(PUSH_URL, data=data, auth=(AccessToken, '')).json()


    except requests.exceptions.ConnectionError:
        traceback.print_exc()
    f.close()

But I keep getting:

requests.exceptions.ConnectionError: HTTPSConnectionPool(host='s3.amazonaws.com', port=443): Max retries exceeded with url: /pushbullet-uploads (Caused by <class 'ConnectionResetError'>: [Errno 104] Connection reset by peer)

If I use another AccessToken I still get this error, even if it's the first time I post to that url.

The upload process is unfortunately not very good and will hopefully be improved soon. It is the one request that does not obey the JSON rule. There is a curl example that shows this (https://docs.pushbullet.com/#upload-request), but understanding curl syntax is basically impossible.

Here's an example that I just typed up and seems to work:

import requests
import json

ACCESS_TOKEN = '<your access token here>'
resp = requests.post('https://api.pushbullet.com/v2/upload-request', data=json.dumps({'file_name': 'image.jpg'}), headers={'Authorization': 'Bearer ' + ACCESS_TOKEN, 'Content-Type': 'application/json'})
if resp.status_code != 200:
    raise Exception('failed to request upload')
r = resp.json()
resp = requests.post(r['upload_url'], data=r['data'], files={'file': open('image.jpg', 'rb')})
if resp.status_code != 204:
    raise Exception('failed to upload file')
print r['file_name'], r['file_type'], r['file_url']

Thank you for this! Note to others: you have to add the final push line after Chris's code to actually make the push. For those having problems like "http://stackoverflow.com/questions/29134512/insecureplatformwarning-a-true-sslcontext-object-is-not-available-this-prevent" please follow the guide here: https://github.com/pyca/cryptography/issues/1981 That is manually install the required utilities like cffi, enum34, ipaddress, idna, pycparser, cryptography. — Sujay Phadke, Oct 04 '16 at 05:01

According to the Pusbullet API

All POST requests should be over HTTPS and use a JSON body with the Content-Type header set to "application/json".

Try changing your requests.post calls like so:

resp = requests.post(UPLOAD_REQUEST_URL, json=data, auth=(AccessToken, '')).json()

Use json=data instead of data=data. Requests will automatically set Content-Type to application/json.

I can't use json=data, I think the version of requests installed on my computer is too old. I also tried to set manually headers={'Content-type': 'application/json'} but I keep getting the same result... – andrew Mar 07 '15 at 20:02
Try updating requests? `pip install requests==2.5.3` – Kedar Mar 08 '15 at 02:23
