REST API اسئلة واجوبة المقابلات

سؤال 11. How big of a payload can you send using POST methods?

There isn't, theoretically, a cap on the size of the payload that can be transmitted via POST methods. Larger payloads, however, may require more bandwidth. As a result, processing the request by the server can take longer.

سؤال 12. Which protocols are used by REST APIs?

REST APIs employ the HTTP protocol for client communication, whereas other protocols are used elsewhere.

سؤال 13. What markup language are used to describe the resources in REST APIs?

Extensible Markup Language (XML) and JSON are used to represent the resources in REST APIs or JavaScript Object Notation.

سؤال 14. Distinguish between POST and PUT techniques.

POST Approach:

• On the server, a resource can be created with POST.
• POST lacks idempotence which means non-idempotent.
• Responses from POST are cacheable.

PUT Approach:

• A resource at a certain URI can be changed to another resource using the PUT command.
• PUT is idempotent, meaning that no matter how many times it is called, only one resource will be produced.
• Responses from PUT are not.

سؤال 15. What does the REST API's caching do?

In order to quickly obtain a server answer in the future, REST API maintains a copy of the response in a specific region of computer memory. Catching is the term for this brief technique.
