Returning clients with post request using WebClient

I have an API documentation. My goal using this doc make a post request to retrieve clients from external api using WebClient. Here the example of the request:

url: "https//:anyurl.com"
{
  "command": "getClients"
}

Here how the response looks like:

{
    "available": true,
    "data": [
        {
           
            "id": "1",
            "name": "Some description",
            "date": "date",
        },
        {
         
            "id": "2",
            "name": "SomeName",
            "date": "date",

        }
    ]
}

Here how I did by now:

public class Main {
    public static void main(String[] args) throws URISyntaxException {
WebClient client = WebClient.create();
MultiValueMap<String, String> bodyValues = new LinkedMultiValueMap<>();
bodyValues.add("command", "getClients");

    WebClient.ResponseSpec response = client.post()
            .uri(new URI("https//:anyurl.com"))
            .header("token", "myToken") //I have a header as well
            .contentType(MediaType.APPLICATION_JSON)
            .accept(MediaType.APPLICATION_JSON)
            .body(BodyInserters.fromFormData(bodyValues))
            .retrieve();


    System.out.println(response);
}

The response class:

public class ClientList {

    
    private Boolean available;
    private List<Clients> data;

}


@Document(collection = "clients")
public class Clients {

    
    @Id
    private Long id;
    private String name;
    private Timestamp date;

//getters and setters
}

By now it returns nothing. Is there any solution?

Can you please try the following? I am guessing that your Mono was not being subscribed and thus the request was never completed.

public class Main {
    public static void main(String[] args) throws URISyntaxException {
        WebClient client = WebClient.create();
        RequestDto requestBody = RequestDto("getClients");

        client.post()
            .uri(new URI("https//:anyurl.com"))
            .header("token", "myToken") //I have a header as well
            .contentType(MediaType.APPLICATION_JSON)
            .accept(MediaType.APPLICATION_JSON)
            .bodyValue(requestBody)
            .retrieve()
            .bodyToMono(ClientList.class)
            .subscribe(response -> System.out.println(response));
    }
}

Assuming you have DTO classes as follows:

public class RequestDto {
    private String command;
    private RequestDataDto data;

    // constructor, getter , setter
}

public class RequestDataDto {
    private int start;
    private int finish;

    // constructor, getter , setter
}

Sending json is the default way for webclient, so all you need to do is to pass in the body correctly. here are the ways:

.body(Mono.just(data))

or:

.body(BodyInserters.fromValue(data))
