✨ PR Review

General Feedback

This PR makes several changes across the codebase including adding exception logging, introducing date tracking for billing, and updating authentication. The changes are generally straightforward but introduce several bugs that need addressing. The most critical issues are a typo in the OrderController causing data mismatch with BillingController, and missing space in the Authorization header token in frontend code.

File: services/orders-java/src/main/java/com/example/orders/controller/OrderController.java
Bug - Field Name Mismatch

Details

Problem: Field Name Mismatch - The OrderController sends a 'dats' field to the billing service, but the BillingController is expecting a 'date' field. This will cause the date information to be lost during serialization/deserialization.
Fix: Rename the field from 'dats' to 'date' to match the expected field name in the BillingController.
Why: The field name typo ('dats' vs 'date') will cause the billing service to receive null for the date field.

payload.put("username", username); payload.put("productId", productId); payload.put("quantity", quantity); -payload.put("dats", Instant.now().toString()); +payload.put("date", Instant.now().toString());

File: frontend/public/app.js
Bug - Invalid Authorization Header

Details

Problem: Invalid Authorization Header - The Authorization header in the placeOrder function is missing a space between 'Bearer' and the token, which will cause authentication to fail.
Fix: Add a space between 'Bearer' and the token in the Authorization header.
Why: The Authorization header format is incorrect. It should be 'Bearer [token]' with a space between 'Bearer' and the token.

headers: { "Content-Type": "application/json", - "Authorization": "Bearer" + token + "Authorization": "Bearer " + token }, body: JSON.stringify({ productId, quantity }), });

File: services/orders-java/src/main/java/com/example/orders/controller/OrderController.java
Security - Exception Leakage

Details

Problem: Exception Leakage - Adding e.printStackTrace() leaks potentially sensitive information to standard error, which could expose implementation details or sensitive data in logs.
Fix: Use a proper logging framework with configurable log levels instead of printStackTrace().
Why: Direct exception printing to standard error is not appropriate for production code as it can expose sensitive information and cannot be easily configured or controlled.

String body = authResponse.getBody(); return body.contains("username") ? body.split(":")[1].replaceAll("[\"{} ]", "") : null; } catch (Exception e) { - e.printStackTrace(); + logger.error("Authentication error: ", e); return null; }

✨ PR Review

General Feedback

The PR introduces several changes across multiple services in the codebase. While some improvements have been made (like adding error logging and handling dates in billing), there are several concerning issues that need to be addressed. The most critical issues include a typo in the payload field, a missing space in the Authorization header token, and removed admin credentials. These issues would likely cause functionality breakage in the application.

File: services/orders-java/src/main/java/com/example/orders/controller/OrderController.java
Bug - Field Typo

Details

Problem: Field Typo - There's a typo in the field name in the payload for the billing service. The field is named 'dats' but the BillingController.cs expects 'date'.
Fix: Rename the field from 'dats' to 'date' to match what the billing service expects
Why: The mismatch between service endpoints will cause data to be lost and potentially break functionality

public class OrderController { JSONObject payload = new JSONObject(); payload.put("username", username); payload.put("productId", productId); payload.put("quantity", quantity); -payload.put("dats", Instant.now().toString()); +payload.put("date", Instant.now().toString());

File: frontend/public/app.js
Bug - Missing Space in Token

Details

Problem: Missing Space in Token - The Authorization header lacks a space between 'Bearer' and the token value, which will cause authentication failures.
Fix: Add the missing space between 'Bearer' and the token
Why: The incorrect format of the Authorization header will cause authentication to fail as the server expects 'Bearer ' format

method: "POST", headers: { "Content-Type": "application/json", - "Authorization": "Bearer" + token + "Authorization": "Bearer " + token }, body: JSON.stringify({ productId, quantity }),

File: services/auth-python/app/auth.py
Security - Removed Admin Credentials

Details

Problem: Removed Admin Credentials - The admin user has been removed from the USER_DB dictionary, which might break administrative functionality in the application.
Fix: Keep the admin user in the USER_DB dictionary unless it's intentionally being deprecated
Why: Removing the admin user without addressing any dependencies could break administrative functionality

USER_DB = { "alice": "password123", - "bob": "hunter2" + "bob": "hunter2", + "admin": "admin" }
