flask get uploaded file size
To get the uploaded file size in Flask, you can follow these steps:
Import the necessary modules: In your Flask application, you'll need to import the
Flask
class and therequest
object from theflask
module. Therequest
object allows you to access the details of the current request.Create a route to handle the file upload: Use the
@app.route
decorator to create a route that will handle the file upload. This route should have the appropriate methods specified (e.g.,POST
).Access the uploaded file: Use the
request.files
attribute to access the uploaded file. This attribute provides a dictionary-like object that contains all the uploaded files. You can access a specific file using its name as the key.Get the file size: Use the
content_length
attribute of the uploaded file to get its size. This attribute returns the size of the file in bytes.Return the file size: You can return the file size as a response to the client or store it in a variable for further processing.
Here's an example code snippet that demonstrates these steps:
from flask import Flask, request
app = Flask(__name__)
@app.route('/upload', methods=['POST'])
def upload():
uploaded_file = request.files['file']
file_size = uploaded_file.content_length
return f'The file size is {file_size} bytes.'
In this example, the upload
function handles the file upload. It accesses the uploaded file using request.files['file']
and gets its size using uploaded_file.content_length
. It then returns the file size as a response.
Remember to replace 'file'
with the actual name of the file input field in your HTML form.
