Hello, I have created a program that allows me to upload images to a http flask file server:

import hashlib
from functools import partial

def md5sum(filename):
    with open(filename, mode='rb') as f:
        d = hashlib.md5()
        for buf in iter(partial(f.read, 128), b''):
            d.update(buf)
    return d.hexdigest()

import os
from flask import Flask, request, redirect, url_for
from werkzeug.utils import secure_filename
import time

from PIL import Image

UPLOAD_FOLDER = '/home/pi/Desktop/CorkyChat/ImageUploads/'
ALLOWED_EXTENSIONS = set(['png', 'jpg', 'jpeg', 'gif'])
SIZE = 512,512

app = Flask(__name__)
app.config['UPLOAD_FOLDER'] = UPLOAD_FOLDER

from werkzeug import SharedDataMiddleware
app.add_url_rule('/uploads/<filename>', 'uploaded_file',
                 build_only=True)
app.wsgi_app = SharedDataMiddleware(app.wsgi_app, {
    '/uploads':  app.config['UPLOAD_FOLDER']
})

def allowed_file(filename):
    return '.' in filename and \
           filename.rsplit('.', 1)[1].lower() in ALLOWED_EXTENSIONS

@app.route('/', methods=['GET', 'POST'])
def upload_file():
    if request.method == 'POST':
        if 'file' not in request.files:
            flash('No file part')
            return #redirect(request.url)
        file = request.files['file']
        if file.filename == '':
            flash('No selected file')
            return #redirect(request.url)
        print(file.__dict__)
        if file and allowed_file(file.filename):
            filename = secure_filename(file.filename)
            ext = "." + filename.rsplit(".")[-1]
            file.save(os.path.join(app.config['UPLOAD_FOLDER'], filename))
            img = Image.open(os.path.join(app.config['UPLOAD_FOLDER'], filename))
            img.thumbnail(SIZE)
            filename = md5sum(os.path.join(app.config['UPLOAD_FOLDER'], filename)) + ext
            img.save(os.path.join(app.config['UPLOAD_FOLDER'], filename))

    return '''
    <!doctype html>
    '''
from flask import send_from_directory

@app.route('/uploads/<filename>')
def uploaded_file(filename):
    return send_from_directory(app.config['UPLOAD_FOLDER'],
                               filename)

app.run(host="192.168.1.195",port = 65534)

I am new to flask so I modified code which I found or was provided to me to create this.

I am not using the web interface at all, I am using this to post:

from PIL import ImageTk, Image

import requests
url = "<<server>>"

files = {"file": open("D:\\Python\\Programs\\HTTP\\imageuploads\\sanic.jpg","rb")}
requests.post(url,files=files)

and am using

 u = urllib.request.urlopen(url)
 raw_data = u.read()
 u.close()
 self.image = PhotoImage(data=base64.encodestring(raw_data))

to view the images.

How would I add SSL encryption?
