Complete the code to define a BFF service that handles client requests.
def bff_service(request): response = [1](request) return response
The BFF service should handle client requests directly, so handle_client_request is the correct function to call.
Complete the code to forward a request from BFF to the appropriate microservice.
def forward_request_to_service(request): service_response = [1](request) return service_response
The BFF forwards requests to microservices by calling their APIs, so call_microservice_api is correct.
Fix the error in the BFF code that aggregates responses from multiple microservices.
def aggregate_responses(responses): combined = {} for response in responses: combined.update([1]) return combined
To update a dictionary with another dictionary's items, use response.items().
Fill both blanks to create a BFF function that filters and transforms data from a microservice.
def process_data(data): filtered = [item for item in data if item [1] 10] transformed = [item[2]2 for item in filtered] return transformed
The function filters items greater than 10 and doubles them by multiplying by 2.
Fill all three blanks to define a BFF caching mechanism that stores and retrieves data.
cache = {}
def get_data(key):
if key in cache:
return cache[[1]]
data = fetch_from_service(key)
cache[[2]] = data
return cache[[3]]The cache uses the same key to check, store, and retrieve data.
