HTTP (Hypertext Transfer Protocol) mein, ek request kya hota hai? What is HTTP request? Explained in simple Hindi

HTTP (Hypertext Transfer Protocol) mein, ek request client se server ki taraf bheji jati hai taki specific action ko perform kiya ja sake ya information retrieve kiya ja sake.

HTTP request ek standard format mein hoti hai, jisme kuch important elements shamil hote hain:

• 1. Request Line:

  - Method: HTTP method batata hai ki client kis tarah ke action ko perform karna chahta hai (e.g., GET, POST, PUT, DELETE).
  - URI (Uniform Resource Identifier): Resource ko identify karne wala URI, jiska server par response diya jayega.
  - HTTP Version: Request mein use hone wale HTTP protocol version ko specify karta hai.

  Example:
  GET /example/resource HTTP/1.1
• 2. Headers:

  - Headers request ke additional information provide karte hain, jaise ki client ki preferences, authentication details, aur content type.

  Example:
  Host: www.example.com
  User-Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/91.0.4472.124 Safari/537.36
• 3. Body (Optional):

  - Body request mein additional data hota hai, jise POST ya PUT requests ke liye use kiya jata hai. Body ke format content type ke hisab se hota hai (e.g., JSON, form data).

  Example:
  POST /example/resource HTTP/1.1
  Content-Type: application/json
  {"key": "value"}

Jab client server ko ek HTTP request bhejta hai, server us request ko process karta hai aur client ko corresponding HTTP response bhejta hai. Ye request-response model web applications aur services ke communication ke liye bahut common hai.
