Spring将动态请求体作为WebClient传递

import org.springframework.web.reactive.function.client.WebClient;
import reactor.core.publisher.Mono;

public class WebClientExample {

    public static void main(String[] args) {
        WebClient webClient = WebClient.builder().build();

        // 动态生成请求体
        String requestBody = "{\"name\": \"John\", \"age\": 30}";

        Mono<String> response = webClient.post()
                .uri("https://api.example.com/user")
                .bodyValue(requestBody) // 使用bodyValue方法传递JSON字符串
                .retrieve()
                .bodyToMono(String.class);

        response.subscribe(System.out::println);
    }
}

import com.fasterxml.jackson.databind.ObjectMapper;

public class WebClientExample {

    public static void main(String[] args) throws Exception {
        WebClient webClient = WebClient.builder().build();

        // 动态生成请求体对象
        User user = new User("John", 30);

        ObjectMapper objectMapper = new ObjectMapper();
        String requestBody = objectMapper.writeValueAsString(user);

        Mono<String> response = webClient.post()
                .uri("https://api.example.com/user")
                .bodyValue(requestBody) // 使用bodyValue方法传递JSON字符串
                .retrieve()
                .bodyToMono(String.class);

        response.subscribe(System.out::println);
    }
}

class User {
    private String name;
    private int age;

    public User(String name, int age) {
        this.name = name;
        this.age = age;
    }

    // Getters and setters
}
