Given the following API Gateway configuration snippet, what will be the response path for a client request to /orders/123?

{
  "/orders": "http://order-service/api/v2/orders"
}

Ahttp://order-service/api/v2/orders/orders/123

Bhttp://order-service/api/v2/orders

Chttp://order-service/orders/123

Dhttp://order-service/api/v2/orders/123

Step-by-Step Solution

Solution:

Step 1: Understand path forwarding in API Gateway
The gateway appends the path after the route key to the backend URL. Here, "/orders" is the route key, so "/123" is appended.
Step 2: Construct the full backend URL
Appending "/123" to "http://order-service/api/v2/orders" results in "http://order-service/api/v2/orders/123".
Final Answer:
http://order-service/api/v2/orders/123 -> Option D
