= `retrieve()`

The `retrieve()` method can be used to declare how to extract the response. For example:

[tabs]
======
Java::
+
[source,java,indent=0,subs="verbatim,quotes",role="primary"]
----
	WebClient client = WebClient.create("https://example.org");

	Mono<ResponseEntity<Person>> result = client.get()
			.uri("/persons/{id}", id).accept(MediaType.APPLICATION_JSON)
			.retrieve()
			.toEntity(Person.class);
----

Kotlin::
+
[source,kotlin,indent=0,subs="verbatim,quotes",role="secondary"]
----
	val client = WebClient.create("https://example.org")

	val result = client.get()
			.uri("/persons/{id}", id).accept(MediaType.APPLICATION_JSON)
			.retrieve()
			.toEntity<Person>().awaitSingle()
----
======

Or to get only the body:

[tabs]
======
Java::
+
[source,java,indent=0,subs="verbatim,quotes",role="primary"]
----
	WebClient client = WebClient.create("https://example.org");

	Mono<Person> result = client.get()
			.uri("/persons/{id}", id).accept(MediaType.APPLICATION_JSON)
			.retrieve()
			.bodyToMono(Person.class);
----

Kotlin::
+
[source,kotlin,indent=0,subs="verbatim,quotes",role="secondary"]
----
	val client = WebClient.create("https://example.org")

	val result = client.get()
			.uri("/persons/{id}", id).accept(MediaType.APPLICATION_JSON)
			.retrieve()
			.awaitBody<Person>()
----
======

To get a stream of decoded objects:

[tabs]
======
Java::
+
[source,java,indent=0,subs="verbatim,quotes",role="primary"]
----
	Flux<Quote> result = client.get()
			.uri("/quotes").accept(MediaType.TEXT_EVENT_STREAM)
			.retrieve()
			.bodyToFlux(Quote.class);
----

Kotlin::
+
[source,kotlin,indent=0,subs="verbatim,quotes",role="secondary"]
----
	val result = client.get()
			.uri("/quotes").accept(MediaType.TEXT_EVENT_STREAM)
			.retrieve()
			.bodyToFlow<Quote>()
----
======

By default, 4xx or 5xx responses result in an `WebClientResponseException`, including
sub-classes for specific HTTP status codes. To customize the handling of error
responses, use `onStatus` handlers as follows:

[tabs]
======
Java::
+
[source,java,indent=0,subs="verbatim,quotes",role="primary"]
----
	Mono<Person> result = client.get()
			.uri("/persons/{id}", id).accept(MediaType.APPLICATION_JSON)
			.retrieve()
			.onStatus(HttpStatus::is4xxClientError, response -> ...)
			.onStatus(HttpStatus::is5xxServerError, response -> ...)
			.bodyToMono(Person.class);
----

Kotlin::
+
[source,kotlin,indent=0,subs="verbatim,quotes",role="secondary"]
----
	val result = client.get()
			.uri("/persons/{id}", id).accept(MediaType.APPLICATION_JSON)
			.retrieve()
			.onStatus(HttpStatus::is4xxClientError) { ... }
			.onStatus(HttpStatus::is5xxServerError) { ... }
			.awaitBody<Person>()
