Is RESTful always JSON?
For some, REST means a server that exchanges JSON documents with a client over HTTP. Not only is that not a complete definition, but it’s also not always true. The REST specification doesn’t require HTTP or JSON. (The spec doesn’t mention JSON or XML at all.)
Is Yaml a JSON?
Although YAML looks different to JSON, YAML is a superset of JSON. As a superset of JSON, a valid YAML file can contain JSON. Additionally, JSON can transform into YAML as well. YAML itself can also contain JSON in its configuration files.
What is the difference between put and POST in rest?
The POST method is used to request that the origin server accept the entity enclosed in the request as a new subordinate of the resource identified by the Request-URI in the Request-Line. PUT replaces the resource in its entirety. Use PATCH if request updates part of the resource.
Can a POST method return data?
Does the RESTlet framework allow returning data in a POST? Yes, even though it returns void, in a class which extends Resource, you have full access to the Response object object via the getResponse() method.
How to return JSON in an apicontroller for one method?
Currently, my ApiController s are returning XML as a response, but for a single method, I want to return JSON. i.e. I can’t make a global change to force responses as JSON.
Which is a valid JSON response for a null value?
This is again another area of debate starts. Options are 1) Do not return NULL values 2) Return as null value. I prefer Option 1) Do not return NULL values. However, question becomes tricky when value is object or array and it is empty. In that case empty {} or [] is valid JSON response.
Which is the rest method in JSON format?
The rest of methods (POST, PUT and DELETE) should have all the information enclosed in the message body in the JSON format. Similarly as with the GET method, DELETE might apply to one specific data, subset of data or all of them (if that’s allowed by the server).
What should be included in a REST API?
REST APIs should accept JSON for request payload and also send responses to JSON. JSON is the standard for transferring data. Almost every networked technology can use it: JavaScript has built-in methods to encode and decode JSON either through the Fetch API or another HTTP client.
