Why consistent formats improve usability in Rest API - Test Your Understanding

Practice - 5 Tasks

1fill in blank

easy

Complete the code to set the Content-Type header for JSON responses.

Rest API

headers = {"Content-Type": "[1]"}

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

Atext/html

Bapplication/json

Capplication/xml

Dtext/plain

💡 Hint

Common Mistakes

Using text/html instead of application/json causes clients to misinterpret the data.

Omitting the Content-Type header leads to inconsistent handling.

Setting the Content-Type to application/json tells clients to expect JSON data, which improves usability by providing a consistent format.

Complete the code to parse a JSON response body.

Rest API

data = response.[1]()

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

Ajson

Btext

Ccontent

Dhtml

💡 Hint

Common Mistakes

Using text() returns raw string, not parsed JSON.

Using html() or content() does not parse JSON.

Using json() parses the response body as JSON, ensuring consistent data format handling.

3fill in blank

hard

Fix the error in the code to send a JSON payload in a POST request.

Rest API

response = requests.post(url, json=[1])

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

B'{"key": "value"}'

C{"key": "value"}

Djson.dumps({"key": "value"})

💡 Hint

Common Mistakes

Passing a JSON string causes the library to send it as a string, not JSON.

Passing None results in no payload sent.

The json parameter expects a Python dictionary, not a string. Passing a dict ensures the library serializes it properly.

4fill in blank

hard

Fill both blanks to create a dictionary comprehension that filters JSON keys starting with 'user'.

Rest API

filtered = {key: value for key, value in data.items() if key [1] 'user'[2]

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

Astartswith

Bendswith

C==

D()

💡 Hint

Common Mistakes

Using '==' compares the whole string, not the start.

Forgetting parentheses causes a syntax error.

Using startswith('user') filters keys that begin with 'user', improving consistent data handling.

5fill in blank

hard

Fill all three blanks to create a JSON response with a consistent format including status and data.

Rest API

response = [1]({{"status": [2], "data": [3])

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

Amake_response

B"success"

Cpayload

Djsonify

Attempts:

💡 Hint

Common Mistakes

Using make_response without JSON conversion.

Passing status as a variable instead of a string.

Forgetting to pass the data dictionary.

Using jsonify creates a JSON response. The status is a string, and data is the payload dictionary, ensuring consistent API output.
