HTTP GET method Because of the good object-oriented design, the HttpClient's constructor is protected. Setup is an async subset of clj-http implemented partially in Java directly. A synchronous client constructs an HTTP structure, sends a request, and waits for a response. Note: You can also send requests asynchronously using the sendAsync() method. In java 11 version it is moved to the java.net.http package. An asynchronous client constructs an HTTP structure, sends a request, and moves on. Easy pluggable Text, JSON, and Bitmap response handlers to parse the response This client tries to follow a similar API inspired by this older now deprecated android-async-http library. The AHC component provides HTTP based endpoints for consuming external HTTP resources (as a client to call external servers using HTTP). We set the asynchronous context timeout to 10 minutes (illustrative value), create a RemoteClient instance containing the AsyncContext and pass it to the background request Dispatcher. Up to Java version 11, the only built-in way to work with HTTP is URLConnection (available since Java 1.0). The code sending a request does not wait for the response to arrive before continuing. The native HttpClient was introduced as an incubator module in Java 9 and then made generally available in Java 11 as a part of JEP 321.
