REST (Representational State Transfer) and SOAP (Simple Object Access Protocol) are two major flavors of Web services architecture. Both provide a means of communication that allows different applications to exchange data with each other over a network. However, there are some important differences between them.
REST
REST is a web-based architectural style that uses the HTTP protocol for communication. The core idea of REST architecture is resources. Resources can be identified by URI (Uniform Resource Identifier), and operated through HTTP protocol, such as GET, POST, PUT and DELETE. RESTful web services typically return data in JSON or XML format.
advantage
- REST is based on the HTTP protocol, so it has good interoperability and scalability.
- REST services can be cached, improving performance and scalability.
- REST services can be implemented using a variety of languages and frameworks.
shortcoming
- REST does not provide standardized security and transaction management functions.
- REST requires coordination between client and server, so it may require more development effort.

SOAP
SOAP is an XML-based protocol for passing messages between Web services. SOAP messages can be transmitted using transport protocols such as HTTP, SMTP, and TCP. SOAP messages are usually encapsulated in XML documents and can be described using WSDL (Web Services Description Language).
advantage
- SOAP provides complete security and transaction management capabilities.
- SOAP's message transport is reliable, with guaranteed delivery.
shortcoming
- The message format of SOAP is more complex than REST, requiring more processing time and bandwidth.
- SOAP services cannot be cached, potentially affecting performance and scalability.

How to debug APIs for REST and SOAP interfaces
Above, we covered the differences between REST and SOAP. So, are there any tools that allow us to call REST or SOAP interfaces simply and efficiently? That is to use Apifox to debug.
For the REST interface, you only need to fill in the URL and request parameters according to the interface agreement, and click "Send" to receive the data returned by the REST interface.
text/xml; charset=utf-8For the SOAP interface, you only need to manually set the Content-Type value of the Header to or according to the actual situation of the interface, application/soap+xmlthen set the Body format to xml, and click "Send" to receive the data in XML format returned by the SOAP interface.
After calling the JSON-RPC interface, we can click the "Save as Interface" button on the right to directly and automatically generate the API interface document.
in conclusion
Both REST and SOAP have their own advantages and disadvantages. REST is a good choice if you need a simple, lightweight web services framework and don't need advanced security and transactional features. If you need a reliable, secure, and powerful Web services framework, SOAP is the better choice. The choice of REST or SOAP depends on the specific application scenarios and needs.
