Solution

  • We can use BodyInserters.fromFormData for this purpose

    webClient client = WebClient.builder()
            .baseUrl("SOME-BASE-URL")
            .defaultHeader(HttpHeaders.CONTENT_TYPE, MediaType.APPLICATION_FORM_URLENCODED_VALUE)
            .build();
    
    return client.post()
            .uri("SOME-URI")
            .body(BodyInserters.fromFormData("username", "SOME-USERNAME")
                    .with("password", "SOME-PASSWORD"))
                    .retrieve()
                    .bodyToFlux(SomeClass.class)
                    .onErrorMap(e -> new MyException("message",e))
            .blockLast();
