Not able to upload a file to slack via web-api

Question

I am trying to upload a file snippet to a channel in slack using Web-API available at https://api.slack.com/methods/files.upload

 payload_channel_caller = {'token': 'xoxpxxxxb1d8529c', 'channel':'C1PJ17FFT', 'file': "/home/nsingh/slack_shift/user_list" ,'title':'Shifters'}

    print "This is a test"
    requests.post('https://slack.com/api/files.upload', data=payload_channel_caller)

But the above code is not able to upload the file, infact it runs right through with no error .

Not sure whats wrong here.

Can someone help me out

Modification points :

In your script, the file you want to upload is not read. When your script is run, following response is retrieved.

{"ok":false,"error":"no_file_data"}

At this time, the status code from Slack is 200. So no error occurs. The script which was reflected above points is as follows.

Modified script :

import requests
uploadfile = "/home/nsingh/slack_shift/user_list"  # Please input the filename with path that you want to upload.
with open(uploadfile, 'rb') as f:
    param = {
        'token': 'xoxpxxxxb1d8529c',
        'channels': 'C1PJ17FFT',
        'title': 'Shifters'
    }
    r = requests.post(
        "https://slack.com/api/files.upload",
        params=param,
        files={'file': f}
    )
    print r.text

If I misunderstand your question, I'm sorry.
