In these examples, --> denotes data sent to a service (request), while <--denotes data coming from a service. Although <--is often called a response in client–server computing, depending on the JSON-RPC version it does not necessarily imply an answer to a request.
JSON-WSP is a web service protocol that uses JSON for service description, requests and responses. [1] It is inspired from JSON-RPC, but the lack of a service description specification with documentation in JSON-RPC sparked the design of JSON-WSP.
Standard response for successful HTTP requests. The actual response will depend on the request method used. In a GET request, the response will contain an entity corresponding to the requested resource. In a POST request, the response will contain an entity describing or containing the result of the action. 201 Created
A typical JSONP request and response are shown below. The function call to parseResponse() is the "P" of JSONP—the "padding" or "prefix" around the pure JSON. [4] For JSONP to work, a server must reply with a response that includes the JSONP function. JSONP does not work with JSON-formatted results.
JSON Schema specifies a JSON-based format to define the structure of JSON data for validation, documentation, and interaction control. It provides a contract for the JSON data required by a given application and how that data can be modified. [ 29 ]
A server-side web API consists of one or more publicly exposed endpoints to a defined request–response message system, typically expressed in JSON or XML. The web API is exposed most commonly by means of an HTTP-based web server. Mashups are web applications which combine the use of multiple server-side web APIs.
It, however, is only defined for the request header. Its meaning in a response header is not specified. [77] The behavior of Pragma: no-cache in a response is implementation specific. While some user agents do pay attention to this field in responses, [78] the HTTP/1.1 RFC specifically warns against relying on this behavior.
The request/response message consists of the following: Request line, such as GET /logo.gif HTTP/1.1 or Status line, such as HTTP/1.1 200 OK, Headers; An empty line; Optional HTTP message body data; The request/status line and headers must all end with <CR><LF> (that is, a carriage return followed by a line feed).
