When MAX_CONTENT_LENGTHis definded, Flask should return an 413, but in my case it resets the connection with this error: Error 101 (net::ERR_CONNECTION_RESET): The connection was reset.
I attached a example built upon the file upload pattern from Flask.
I use Chrome 15.0.874.5.
import os
from flask import Flask, request, redirect, url_for, send_from_directory
from werkzeug import secure_filename
UPLOAD_FOLDER = 'uploads/'
ALLOWED_EXTENSIONS = set(['txt', 'pdf', 'png', 'jpg', 'jpeg', 'gif','bib','mp3'])
app = Flask(__name__)
app.config['UPLOAD_FOLDER'] = UPLOAD_FOLDER
def allowed_file(filename):
return '.' in filename and \
filename.rsplit('.', 1)[1] in ALLOWED_EXTENSIONS
@app.route('/', methods=['GET', 'POST'])
def upload_file():
if request.method == 'POST':
file = request.files['file']
if file and allowed_file(file.filename):
filename = secure_filename(file.filename)
file.save(os.path.join(app.config['UPLOAD_FOLDER'], filename))
return redirect(url_for('uploaded_file',
filename=filename))
return '''
<!doctype html>
<title>Upload new File</title>
<h1>Upload new File</h1>
<form action="" method=post enctype=multipart/form-data>
<p><input type=file name=file>
<input type=submit value=Upload>
</form>
'''
@app.route('/uploads/<filename>')
def uploaded_file(filename):
return send_from_directory(app.config['UPLOAD_FOLDER'],
filename)
@app.errorhandler(413)
def file_to_big(e):
return 'File to big'
if __name__ == '__main__':
app.config['MAX_CONTENT_LENGTH'] = 1024 * 1024
app.run(debug=True)
