What components does an HTTP request consist of?

The HTTP request consists of the following components:

1. Request Line:

   • HTTP Method (GET, POST, PUT, DELETE, etc.).
   • Resource path (URL).
   • HTTP protocol version (HTTP/1.1, HTTP/2.0, etc.).

   // Example of request line:
   GET /index.html HTTP/1.1
   

2. Headers:

   • Send additional information about the request, client, or resource.
   • Each header is a key-value pair.

   // Examples of headers:
   Host: www.example.com
   User-Agent: Mozilla/5.0 (...)
   Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8
   

3. Empty line:

   • Separates headers from the request body.

   // Empty line between headers and request body
   

4. Request Body:

   • Contains data sent to the server, if applicable (e.g., in POST or PUT methods).
   • The format of the body is determined by the Content-Type header.

   // Example of request body in JSON format:
   {
     "name": "John Doe",
     "occupation": "Software Engineer"
   }
