Jeg kjører en kolbe program på en Ubuntu 18.04 system med Apache 2 og uWSGI. Når jeg prøver å laste opp filer til en katalog, mislykkes det med en 500 feilkode. Manuset er skrevet i __init__.pyog ligger på: /var/www/FlaskApp/FlaskApp/__init__.py. Katalogen for opplastede filer ligger på: /var/www/FlaskApp/FlaskApp/uploads. Manuset ser ut som følgende:
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()
Det viser HTML-siden, men når jeg klikker på Send når du har valgt filer, den svikter. Jeg har prøvd å kjøre koden både med og uten kommentarer, men det fortsatt ikke. Jeg tror feilen oppstår på: file.save(os.path.join(app.config['UPLOAD_FOLDER'], filename))
Jeg har også prøvd flere forskjellige baner. Kan det være noe galt med konfigurasjonen av app? Jeg tror ikke jeg har en reell settings.py, hvis det skulle saken.
Tusen takk for svar
