Python 3 Script To Upload A File To A Rest Url (multipart Request)

I am fairly new to Python and using Python 3.2. I am trying to write a python script that will pick a file from user machine (such as an image file) and submit it to a server using

Solution 1:

Requests library is what you need. You can install with pip install requests.

http://docs.python-requests.org/en/latest/user/quickstart/#post-a-multipart-encoded-file

>>>url = 'http://httpbin.org/post'>>>files = {'file': open('report.xls', 'rb')}>>>r = requests.post(url, files=files)

Solution 2:

A RESTful way to upload an image would be to use PUT request if you know what the image url is:

#!/usr/bin/env python3import http.client 

h = http.client.HTTPConnection('example.com')
h.request('PUT', '/file/pic.jpg', open('pic.jpg', 'rb'))
print(h.getresponse().read())

upload_docs.py contains an example how to upload a file as multipart/form-data with basic http authentication. It supports both Python 2.x and Python 3.

You could use also requests to post files as a multipart/form-data:

#!/usr/bin/env python3import requests

response = requests.post('http://httpbin.org/post',
                         files={'file': open('filename','rb')})
print(response.content)

Solution 3:

You can also use unirest . Sample code

import unirest

# consume async post requestdefconsumePOSTRequestSync():
 params = {'test1':'param1','test2':'param2'}

 # we need to pass a dummy variable which is open method# actually unirest does not provide variable to shift between# application-x-www-form-urlencoded and# multipart/form-data
 params['dummy'] = open('dummy.txt', 'r')
 url = 'http://httpbin.org/post'
 headers = {"Accept": "application/json"}
 # call get service with headers and params
 response = unirest.post(url, headers = headers,params = params)
 print"code:"+ str(response.code)
 print"******************"print"headers:"+ str(response.headers)
 print"******************"print"body:"+ str(response.body)
 print"******************"print"raw_body:"+ str(response.raw_body)

# post sync request multipart/form-data
consumePOSTRequestSync()
