Interface WebClient

public interface WebClient

Non-blocking, reactive client to perform HTTP requests, exposing a fluent, reactive API over underlying HTTP client libraries such as Reactor Netty.

Use static factory methods create() or create(String), or builder() to prepare an instance.

For examples with a response body see retrieve() and exchange(). For examples with a request body see body(Publisher,Class), syncBody(Object), and body(BodyInserter).
