RESTful trigger function

php editor Xinyi today introduces to you a powerful development technology-RESTful trigger function. RESTful is a design style that makes communication between different systems more concise and efficient by using unified interface specifications. The trigger function refers to automatically triggering the corresponding operation or function when a specific event occurs. Combined with RESTful and trigger functions, more flexible and intelligent application development can be achieved. This article will introduce in detail the principles, application scenarios and implementation methods of RESTful triggering function to help developers better master this technology.

Question content

I have java Restful service and its functions are running as planned. I want to implement a way to run this function on demand. What is the correct/most efficient way to achieve this?

Solution

"Just use POST." (Fielding, 2009)

Simulation: If you are building a boring website, then you will provide the operator with a web form that contains a "submit" button that will send a request to the web server. You probably don't want to preemptively submit the form, so you can set the form method to POST so that the generic component understands that the semantics of the form are not "safe".

That is, you can design interactions using the metaphor of passing a new document to the server for storage, where the storage of that document will trigger the side effects you want. In other words, you can treat the message itself as a resource and use remote authoring semantics (PUT/DELETE/PATCH) to transfer that information to the server.

As far as REST goes, both options are good.

From a REST perspective, the fact that the message itself has no explicit "state" is not important at all.
