Używam aplikacji Kolba na systemie Ubuntu 18.04 z Apache 2 i uWSGI. Kiedy próbuję wgrać pliki do katalogu, nie jest on z kodem 500 błędu. Skrypt jest napisany w __init__.pyi znajduje się pod adresem: /var/www/FlaskApp/FlaskApp/__init__.py. Katalog dla plików przesłanych znajduje się pod adresem: /var/www/FlaskApp/FlaskApp/uploads. Skrypt wygląda jak następuje:
from flask import Flask, render_template, request, url_for, redirect,
send_from_directory, send_file, flash
from werkzeug.utils import secure_filename
import os
UPLOAD_FOLDER = '/var/www/FlaskApp/FlaskApp/uploads'
#ALLOWED_EXTENSIONS = set(['txt', 'pdf', 'png', 'jpg', 'jpeg', 'gif'])
app = Flask(__name__)
app.config['UPLOAD_FOLDER'] = UPLOAD_FOLDER
@app.route('/test/', 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)
#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 method=post enctype=multipart/form-data>
<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)
if __name__ == '__main__':
app.run()
Wyświetla stronę HTML, ale po kliknięciu złożyć po wybraniu plików, to się nie powiedzie. Próbowałem uruchomić kod zarówno z jak i bez uwag, ale jeszcze się nie powiedzie. Myślę, że błąd występuje u: file.save(os.path.join(app.config['UPLOAD_FOLDER'], filename))
Próbowałem również kilka różnych ścieżek. To może być coś nie tak z konfiguracją aplikacji? Nie sądzę, że mam prawdziwe settings.py, czy to powinno mieć znaczenia.
Bardzo dziękuję za odpowiedzi
