Prompt Detail:
Sure! Here's a simple example of a web service using Python and Flask that stores and retrieves a hash value:
pythonfrom flask import Flask, request
app = Flask(__name__)
hash_value = None # Store the hash value in memory
@app.route('/hash', methods=['GET', 'POST'])
def handle_hash():
global hash_value # Use the global hash_value variable
if request.method == 'POST':
# Store the hash value from the POST request
hash_value = request.form['hash']
return 'Hash value has been stored successfully.'
elif request.method == 'GET':
# Return the stored hash value for GET request
if hash_value:
return hash_value
else:
return 'No hash value has been stored yet.'
if __name__ == '__main__':
app.run(debug=True) # Start the Flask web service in debug mode
This code defines a simple Flask web service with a single endpoint /hash
that can handle both GET and POST requests. When a POST request is received with a hash value in the request body, it stores the hash value in the hash_value
variable. When a GET request is received, it returns the stored hash value if it exists, or a message indicating that no hash value has been stored yet.
You can run this code on a web server with Python and Flask installed. After starting the web service, you can access it at http://localhost:5000/hash
. To store a hash value, you can send a POST request to the same URL with the hash value as the request body. To retrieve the stored hash value, you can send a GET request to the same URL. Your program can use HTTP libraries like requests
in Python to interact with this web service and retrieve the stored hash value.
