The Demo code below contains detailed html pages and python code
import os# We'll render HTML templates and access data sent by POST# using the request object from flask. Redirect and url_for# will be used to redirect the user once the upload is done# and send_from_directory will help us to send/show on the# browser the file that the user just uploadedfrom flask import Flask, render_template, request, redirect, url_for, send_from_directoryfrom werkzeug import secure_filename# Initialize the Flask applicationapp = Flask(__name__)# This is the path to the upload directoryapp.config['UPLOAD_FOLDER'] = 'uploads/'# These are the extension that we are accepting to be uploadedapp.config['ALLOWED_EXTENSIONS'] = set(['txt', 'pdf', 'png', 'jpg', 'jpeg', 'gif'])# For a given file, return whether it's an allowed type or notdef allowed_file(filename): return '.' in filename and \ filename.rsplit('.', 1)[1] in app.config['ALLOWED_EXTENSIONS']# This route will show a form to perform an AJAX request# jQuery is loaded to execute the request and update the# value of the operation@app.route('/')def index(): return render_template('index.html')# Route that will process the file upload@app.route('/upload', methods=['POST'])def upload(): # Get the name of the uploaded files uploaded_files = request.files.getlist("file[]") filenames = [] for file in uploaded_files: # Check if the file is one of the allowed types/extensions if file and allowed_file(file.filename): # Make the filename safe, remove unsupported chars filename = secure_filename(file.filename) # Move the file form the temporal folder to the upload # folder we setup file.save(os.path.join(app.config['UPLOAD_FOLDER'],filename)) # Save the filename into a list, we'll use it later filenames.append(filename) # Redirect the user to the uploaded_file route, which # will basicaly show on the browser the uploaded file # Load an html page with a link to each uploaded file return render_template('upload.html', filenames=filenames) # This route is expecting a parameter containing the name# of a file.
