easy

Complete the code to define an HTTP triggered Cloud Function in Python.

GCP

    return [1]('Hello, World!')

Drag options to blanks, or click blank then click option'

💡 Hint

Common Mistakes

Using print instead of returning a response

Returning a plain string without wrapping in a response

The function must return a proper HTTP response. make_response creates a valid HTTP response object.

2fill in blank

medium

Complete the code to extract a query parameter named 'name' from the HTTP request.

GCP

def greet(request):
    name = request.args.get([1], 'Guest')
    return f'Hello, {name}!'

Drag options to blanks, or click blank then click option'

A'user'

B'name'

C'id'

D'guest'

💡 Hint

Common Mistakes

Using the wrong parameter name

Forgetting to provide a default value

The query parameter to extract is named 'name'. Using request.args.get('name') retrieves it.

3fill in blank

hard

Fix the error in the code to correctly handle JSON data from the HTTP POST request.

GCP

def process_json(request):
    data = request.[1]
    return f"Received: {data['message']}"

Drag options to blanks, or click blank then click option'

Aget_json

Bjson

Cjson_data

Djson()

💡 Hint

Common Mistakes

Calling get_json() on request.json which is already parsed

Using incorrect attribute names

The request object has a get_json() method that parses the JSON data. Using request.json is also valid but here the correct fix is to use get_json().

4fill in blank

hard

Fill both blanks to create a Cloud Function that returns a JSON response with a status code 200.

GCP

from flask import jsonify, make_response

def json_response(request):
    data = {'message': 'Success'}
    response = make_response([1](data), [2])
    return response

Drag options to blanks, or click blank then click option'

B404

C200

Djson

💡 Hint

Common Mistakes

Using wrong status code

Not converting data to JSON properly

jsonify converts the dictionary to a JSON response. The status code 200 means success.

5fill in blank

hard

Fill all three blanks to create a Cloud Function that reads a JSON field 'name', returns a greeting, and sets content type.

GCP

from flask import make_response, jsonify

def greet_user(request):
    data = request.[1]
    name = data.get([2], 'Guest')
    response = make_response(jsonify({'greeting': f'Hello, {name}!'}))
    response.headers['[3]'] = 'application/json'
    return response

Drag options to blanks, or click blank then click option'

Ajson

B'name'

CContent-Type

Dargs

Attempts:

3 left

💡 Hint

Common Mistakes

Using request.args instead of request.json

Forgetting to set the content type header

Using wrong key names

request.json accesses JSON data. The key to get is 'name'. The header to set content type is 'Content-Type'.
