Difference between Proxy Service and API Service i

问题:

What is the difference between a Proxy service and API service in wso2esb?

To expose my service I can give proxy URL and API URL then in which scenario both differs? and in which scenario I can use proxy and in which I can use API?

Please help me in understanding..,

回答1:

An API has resources so it is suitable when you have to perform multiple operations like CRUD etc. then you can call particular resource which will be performing some particular operation.

A proxy service is suitable when you have to perform an isolated operation (single operation).

So, what you can do is, make an API for multiple operations and then create proxy services for each operation.

Moreover, API can be called as REST service and Proxy service is called as a soap service.

Use a proxy service to expose a SOAP web service

You can consume JMS messages or files with VFS, but since ESB 4.9.0 you can use inbound endpoints for that purpose

Use API to expose a REST service
