4 months ago @kaenugget I need your help with this, here is my progress:
To address the issues you've outlined regarding the workflow, we need to implement a series of microservices that interact with each other to fulfill the entire process from selecting study resources to acknowledging the invoice. Below, I will provide a high-level overview and code snippets for each step of the workflow.
Step 1: Marketplace UI and Payment Processing
You will need a web framework (like Flask) to create the UI and handle payment processing. Below is a simplified example of how to implement the UI and payment processing:
{python}
from flask import Flask, request, jsonify
import stripe
app = Flask(__name__)
# Set your secret key. Remember to switch to your live secret key in production!
stripe.api_key = 'your_secret_key'
@app.route('/checkout', methods=['POST'])
def checkout():
data = request.json
try:
# Create a payment method
payment_method = stripe.PaymentMethod.create(
type="card",
card={
"number": data['card_number'],
"exp_month": data['exp_month'],
"exp_year": data['exp_year'],
"cvc": data['cvc'],
},
)
# Invoke the Purchase Study Resource (PSR) microservice
psr_response = requests.post('http://psr-ms-url/purchase', json={
"user_id": data['user_id'],
"seller_id": data['seller_id'],
"payment_method_id": payment_method.id,
"total_price": data['total_price'],
"description": data['description']
})
return psr_response.json(), psr_response.status_code
except Exception as e:
return jsonify(error=str(e)), 403
if __name__ == '__main__':
app.run(debug=True)Step 2: PSR Microservice
The PSR microservice will handle the purchase logic and communicate with the User MS to retrieve seller payment credentials.
{python}
from flask import Flask, request, jsonify
import requests
app = Flask(__name__)
@app.route('/purchase', methods=['POST'])
def purchase():
data = request.json
seller_id = data['seller_id']
# Invoke User MS to get seller payment credentials
user_response = requests.get(f'http://user-ms-url/seller/{seller_id}/credentials')
if user_response.status_code == 200:
seller_credentials = user_response.json()
# Now invoke Payment MS
payment_response = requests.post('http://payment-ms-url/process', json={
"user_id": data['user_id'],
"seller_id": seller_id,
"total_price": data['total_price'],
"description": data['description'],
"stripe_account_id": seller_credentials['StripeAccountID'],
"payment_method_id": data['payment_method_id']
})
if payment_response.status_code == 200:
# Successful payment, now get resource links
resource_response = requests.get('http://studyresource-ms-url/resources', params={"seller_id": seller_id})
return resource_response.json(), resource_response.status_code
else:
return jsonify({"error": "Payment processing failed"}), 400
else:
return jsonify({"error": "Failed to retrieve seller credentials"}), 400
if __name__ == '__main__':
app.run(port=5001, debug=True)Step 3: User Microservice
This microservice will validate requests and provide seller payment credentials.
{python}
from flask import Flask, jsonify
app = Flask(__name__)
@app.route('/seller/<seller_id>/credentials', methods=['GET'])
def get_seller_credentials(seller_id):
# Here you would typically fetch the seller's credentials from a database
return jsonify({"StripeAccountID": "acct_1234567890"}), 200
if __name__ == '__main__':
app.run(port=5002, debug=True)Step 4: Payment Microservice
This microservice will process payments using the Stripe API.
{python}
from flask import Flask, request, jsonify
import stripe
app = Flask(__name__)
stripe.api_key = 'your_secret_key'
@app.route('/process', methods=['POST'])
def process_payment():
data = request.json
try:
# Process the payment
charge = stripe.Charge.create(
amount=int(data['total_price'] * 100), # Amount in cents
currency='usd',
source=data['payment_method_id'],
description=data['description'],
destination={
'account': data['stripe_account_id'],
},
)
return jsonify({"status": "success", "charge_id": charge.id}), 200
except Exception as e:
return jsonify({"error": str(e)}), 400
if __name__ == '__main__':
app.run(port=5003, debug=True)Step 5: Study Resource Microservice
This microservice will retrieve resource links based on the seller ID.
{python}
from flask import Flask, jsonify
app = Flask(__name__)
@app.route('/resources', methods=['GET'])
def get_resources():
seller_id = request.args.get('seller_id')
# Here you would typically fetch the resource URLs from a database or S3
return jsonify({"resource_links": ["https://s3.amazonaws.com/bucket/resource1", "https://s3.amazonaws.com/bucket/resource2"]}), 200
if __name__ == '__main__':
app.run(port=5004, debug=True)Step 6: Notification Microservice
This microservice will handle sending notifications.
{python}
from flask import Flask, request, jsonify
app = Flask(__name__)
@app.route('/notify', methods=['POST'])
def notify():
data = request.json
# Here you would send a notification to the user via Telegram
return jsonify({"status": "notification sent"}), 200
if __name__ == '__main__':
app.run(port=5005, debug=True)Step 7: Invoice Submission and Acknowledgment
You can implement endpoints for invoice submission and acknowledgment in the appropriate microservice.
{python}
@app.route('/invoice', methods=['POST'])
def submit_invoice():
data = request.json
# Process the invoice submission
return jsonify({"status": "invoice submitted"}), 200
@app.route('/acknowledge', methods=['POST'])
def acknowledge():
data = request.json
# Process the acknowledgment
return jsonify({"status": "acknowledged"}), 200Summary
- Step 1: Implement the Marketplace UI to handle payment processing and invoke the PSR microservice.
- Step 2: Create the PSR microservice to handle purchases and communicate with the User MS.
- Step 3: Implement the User microservice to provide seller payment credentials.
- Step 4: Create the Payment microservice to process payments using Stripe.
- Step 5: Implement the Study Resource microservice to retrieve resource links.
- Step 6: Create the Notification microservice to send notifications.
- Step 7: Implement endpoints for invoice submission and acknowledgment.
Make sure to replace placeholder values and implement proper error handling and security measures in a production environment. This structure should help fulfill all the criteria outlined in your issue description.

{ step 1: "Student filter and select the study resources he/she wants to purchase on Marketplace UI, go to the cart page, enter their credit card details (Number, Expiration Date, CVC) and click on the submit payment button. UI generates paymentmethodID via Stripe API and invokes Purchase Study Resource(PSR) microservice (MS) and send all information to PSR" (not fulfilled, Reason: "The provided code does not include any implementation or interaction with the Marketplace UI or the payment process, indicating that this step is not executed.")
