In this example I will show you how to upload, download, delete and obtain files with Flask
Upload multiple files with Form Data
from flask import Flask
import os
app = Flask(__name__)
@app.route("/upload", methods=['POST'])
def upload_image():
if request.method == "POST":
file = request.files['file']
try:
file.save(os.getcwd() + "/images/" + file.filename)
return "Imagen saved"
except FileNotFoundError:
return "Folder not found"
if __name__ == '__main__':
app.run(debug=True, port=8000, host="0.0.0.0")
Download files
from flask import Flask
import os
app = Flask(__name__)
@app.route('/download/file/<string:filename>')
def download_image(filename):
return send_from_directory(os.getcwd() + "/images/", path=filename, as_attachment=True)
if __name__ == '__main__':
app.run(debug=True, port=8000, host="0.0.0.0")
Get files
from flask import Flask
import os
app = Flask(__name__)
@app.route('/file/<string:filename>')
def get_image(filename):
return send_from_directory(os.getcwd() + "/images/", path=filename, as_attachment=False)
if __name__ == '__main__':
app.run(debug=True, port=8000, host="0.0.0.0")
Delete files
from flask import Flask
import os
app = Flask(__name__)
@app.route('/delete', methods=['POST'])
def remove_image():
filename = request.form['filename']
# CHECK IF EXISTS FILE
if os.path.isfile(os.getcwd() + "/images/" + filename) == False:
return "Esto no es un archivo"
else:
try:
os.remove(os.getcwd() + "/images/" + filename)
except OSError:
return "Error :(("
return "File deleted"
if __name__ == '__main__':
app.run(debug=True, port=8000, host="0.0.0.0")
