#Upload a file and play using arraysync code#

In the above code, we use python for loop to iterate over the list of files and then save each file one by one. If we upload a file that does not have the extension of PDF, JPG, PNG, then the server will show the message as shown in the below image.įiles = ('files') # get the file from the files object In the above code, we create a function that will check the uploaded file extension and compare it with the allowed extensions. Return 'The file extension is not allowed' Return filename.split('.') in allowed_extensions

#Upload a file and play using arraysync code#

For example, if we want to limit the maximum size of the file to 1 Mb, we need to add the following line of code in our program.Īpp.config = 1 * 1024 * 1024Īllowed_extensions = To configure the maximum file size, we need to set the app.config variable to the maximum size of the file in bytes. So, we need to always limit the upload size of the file according to our server.

This is important because if the file is too large for the server, then the site may crash. We can also configure the maximum upload size of the file. If we restart the server and upload a file to the server, the file will be uploaded to the created directory instead of the root directory. Step 2: Create a Google Wallet Merchant and Link it to Your Developer Account. In the above code, we use the OS module of python to create a directory and saves every uploaded file to the created directory. # Saving the file in the required destinationį.save(os.path.join(app.config ,secure_filename(f.filename))) # this will secure the file We will see something as shown in the below image while running the above code.Īpp.config = upload_folder You can run the above code by just typing python app.py in the terminal. Next, we use python decorators to accept the post request for the file and save the file. Next, we use python decorators to define the routes for our Flask app and serve the HTML template that we created. After importing the required modules, we initialize the Flask app by calling the Flask() constructor. In the above code, we first imported the required modules to our code. Return 'file uploaded successfully' # Display thsi message after uploading If thod = 'POST': # check if the method is postį = request.files # get the file from the files objectį.save(secure_filename(f.filename)) # this will secure the file # The path for uploading the upload_file(): From flask import Flask, render_template, requestįrom werkzeug.utils import secure_filename
