The Authorization header is commonly used for passing authentication tokens in RESTful services.
In terms of interoperability, what is a significant advantage of RESTful services over SOAP-based services?
- Lightweight and easy to integrate
- Optimizes complex data processing tasks
- Provides advanced security features
- Supports remote procedure calls (RPC)
A significant advantage of RESTful services in terms of interoperability is their lightweight nature and ease of integration. RESTful services use standard HTTP methods and simple data formats, making them more accessible and adaptable across different platforms. This simplicity promotes interoperability, especially in scenarios where resource constraints or diverse technology stacks are prevalent.
SOAP is based on which standard communication protocol?
- HTTP
- SMTP
- TCP
- XML
SOAP (Simple Object Access Protocol) is based on XML, which serves as the standard communication protocol. XML provides a platform-independent and extensible format for encoding data, ensuring interoperability between different systems and programming languages.
