Estoy corriendo una aplicación frasco en un sistema Ubuntu 18.04 con Apache 2 y uWSGI. Cuando trato de cargar archivos en un directorio, se produce un error con un código de error 500. El guión está escrito en el __init__.pyy ubicado en: /var/www/FlaskApp/FlaskApp/__init__.py. El directorio para los archivos subidos se encuentra en: /var/www/FlaskApp/FlaskApp/uploads. La secuencia de comandos se parece a lo siguiente:
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()
Se muestra la página HTML, pero cuando lo haga clic en enviar después de seleccionar los archivos, falla. He tratado de ejecutar el código con y sin los comentarios, pero no lo consigo. Creo que el error se produce en el: file.save(os.path.join(app.config['UPLOAD_FOLDER'], filename))
varios caminos diferentes También he probado. Podría haber algo mal con la configuración de la aplicación? No creo que tengo una settings.py real, si que debería importar.
Muchas gracias por las respuestas
