Rest API - Request and Response Format

You wrote this HTTP request:

POST /submit HTTP/1.1
Host: example.com
Content-Type: application/json
Accept: application/json

name=John&age=30

Why might the server reject this request or fail to parse the data?

BBecause the Content-Type says JSON but the body is URL-encoded form data

CBecause Accept header is incorrect for JSON

DBecause the Host header is missing

Step-by-Step Solution

Solution:

Step 1: Check Content-Type and body format
The Content-Type is application/json, but the body is name=John&age=30, which is URL-encoded form data, not JSON.
Step 2: Understand server parsing behavior
The server expects JSON data but receives form data, so it may reject or fail to parse the request.
Final Answer:
Because the Content-Type says JSON but the body is URL-encoded form data -> Option B
Quick Check:
Content-Type must match body format [OK]

Quick Trick: Match Content-Type with actual body format [OK]
