Practice

1. What is the main purpose of a GET request in web communication?

easy

A. To ask for data without changing anything on the server

B. To send data to create or update information on the server

C. To delete data from the server

D. To authenticate a user

Solution

1. Step 1: Understand the role of GET requests

   GET requests are used to retrieve or ask for data from a server without making any changes.

2. Step 2: Compare with other request types

   POST requests send data to the server to create or update information, unlike GET which only reads data.

3. Final Answer:

   To ask for data without changing anything on the server -> Option A

4. Quick Check:

   GET = Read data [OK]

Hint: GET requests only fetch data, no changes made [OK]

Common Mistakes:

• Confusing GET with POST as both send data
• Thinking GET changes server data
• Assuming GET deletes data

2. Which of the following is the correct way to send data using a POST request in a typical web form?

easy

A. Using URL parameters like ?name=John&age=30

B. Sending data as a cookie only

C. Appending data to the URL path directly

D. Including data in the request body, not visible in the URL

Solution

1. Step 1: Identify how POST sends data

   POST requests send data inside the request body, which is not shown in the URL.

2. Step 2: Differentiate from GET request data sending

   GET requests send data via URL parameters, visible after a question mark, unlike POST.

3. Final Answer:

   Including data in the request body, not visible in the URL -> Option D

4. Quick Check:

   POST = Data in body [OK]

Hint: POST data goes in body, not URL [OK]

Common Mistakes:

• Using URL parameters for POST data
• Confusing GET and POST data locations
• Thinking POST data is visible in URL

3. Consider a web page that uses a GET request to fetch user details and a POST request to update user details. What will happen if you try to update user details using a GET request instead?

medium

A. The server will ignore the update and only send data

B. The server will return an error because GET cannot update data

C. The user details will be updated successfully

D. The server will delete the user details

Solution

1. Step 1: Understand GET request behavior

   GET requests are designed to retrieve data and should not change server data.

2. Step 2: Predict server response to update attempt via GET

   Most servers ignore any update attempts sent via GET and just return the requested data.

3. Final Answer:

   The server will ignore the update and only send data -> Option A

4. Quick Check:

   GET = Read only, no update [OK]

Hint: GET never updates, server ignores update attempts [OK]

Common Mistakes:

• Assuming GET can update data
• Expecting an error always on wrong method
• Confusing GET with POST behavior

4. A developer wrote this code to send data to a server:

fetch('https://api.example.com/data', {
  method: 'GET',
  body: JSON.stringify({name: 'Alice'})
})

What is the main problem with this code?

medium

A. The URL is incorrect for sending data

B. The method should be lowercase 'get'

C. GET requests should not have a body; data won't be sent

D. JSON.stringify cannot be used in fetch

Solution

1. Step 1: Check HTTP method and body usage

   GET requests do not support sending a body; any body is ignored by browsers and servers.

2. Step 2: Identify correct method for sending data

   To send data in the body, the method should be POST or PUT, not GET.

3. Final Answer:

   GET requests should not have a body; data won't be sent -> Option C

4. Quick Check:

   GET = No body allowed [OK]

Hint: GET requests never send body data [OK]

Common Mistakes:

• Adding body to GET requests
• Using wrong HTTP method case
• Thinking JSON.stringify is invalid in fetch

5. You want to build a form that submits user feedback without changing the page URL or showing data in the URL bar. Which request method should you use and why?

hard

A. GET, because it is faster and shows data in URL

B. POST, because it sends data in the request body and keeps URL clean

C. GET, because it can send large amounts of data securely

D. POST, because it appends data to the URL for easy sharing

Solution

1. Step 1: Identify the requirement to keep URL clean

   Showing data in the URL bar means using GET, which appends data as URL parameters.

2. Step 2: Choose method that sends data in body and keeps URL unchanged

   POST sends data in the request body, so the URL stays clean and data is not visible.

3. Final Answer:

   POST, because it sends data in the request body and keeps URL clean -> Option B

4. Quick Check:

   POST = Data in body, URL clean [OK]

Hint: Use POST to hide data from URL [OK]

Common Mistakes:

• Choosing GET to hide data
• Thinking GET can send large secure data
• Confusing URL visibility with request speed
