Handling Requests & Responses
Master how to parse incoming request data and construct appropriate HTTP responses, including JSON and HTML.
Handling Requests & Responses
In web development, your application constantly handles incoming requests from clients and sends back appropriate responses. This lesson teaches you how to read data from a client's request and construct different types of responses, like HTML and JSON, using Clojure's Ring.
Understanding the Ring Request Map
When a request hits your Clojure application, Ring transforms it into a standard Clojure map, often called the request map. This map contains all details about the incoming request, such as:
:uri: The path of the request (e.g.,"/users"):request-method: The HTTP method (e.g.,:get,:post):headers: A map of all HTTP headers:query-params: A map of URL query parameters:body: The request body, if any
