Use python to connect to a php page and upload image

Question

I would like to know if its possible to use python to connect to a certain site

and upload an image from the computer. Basically I have a python script that takes images from the webcam. Now after it takes the image how can i send that image to a webpage. If you tell me how to get it to connect to the page I can handle the rest. Thanks in advance!

THIS IS THE PYTHON SCRIPT AT HAND:

from VideoCapture import Device

cam = Device(devnum=1)
cam.saveSnapshot('image.jpg', timestamp=3, boldfont=1)

Use urllib2 for this. Basically build up a urllib2.Request with the URL to the PHP script, and then add_data to add the image data that you want to submit.

edit: you can follow the examples here, and specifically this example to help understand the full process

Tip for the OP: You'll be using a POST request to send the image data, not GET.

this is great but can you further explain how to add_data. I am fairly new to python.

I advice you to learn "mechanize" library http://wwwsearch.sourceforge.net/mechanize/ It very easy to use.

This is example from one of my scripts.

def upload_and_get_data(username, password, image_filename):
    print image_filename, type(image_filename)
    browser = mechanize.Browser()
    browser.open("http://itmages.ru/user/login")
    form = browser.form = browser.forms().next()
    form["LoginForm[username]"] = username
    form["LoginForm[password]"] = password
    login_response = browser.submit()

    # file uploading
    form = browser.form = browser.forms().next()
    form.add_file(open(image_filename, "r"),
                  filename=os.path.basename(image_filename))
    send_response = browser.submit()

    table_regex = re.compile('<table class="stat".*?<input.*?</table>')
    table_data_text = table_regex.findall(
        send_response.get_data().replace("\n", " "))[0]
    table_data_regex = re.compile(
        '<tr> *<td.*?<b>([^<]*)</b></td> *<td>(.*?)</td> *</tr>')
    table_data = dict(table_data_regex.findall(table_data_text))
    return table_data

if i add this function to my script how can I use the image from VideoCapture and put it into the image_filename variable?

Vladimir Lagunov Over a year ago

do you save your image on disk? If yes, you must know image's filename. Just pass those file contents and it's name to add_file. Otherwise, use StringIO and some spoof filename.

maybe i don't understood you. This method works with forms enctype="multipart/form-data"

@werehuman Okay but my issue is how to pass the name to add_file. Lets say i stored the location to the image as f. would the function then be: def upload_and_get_data(username, password, f):?

If he has a URL and an API he can build against why would he rely on the presentation layer of the form instead?

Of course. Open the file, and use urllib:

imgfile = open("image.jpg", "rb")
urllib.urlopen("http://www.example.com/", imgfile.read())
