如何通过retrofit2将JSON数组发布到android的服务器？

implementation 'com.squareup.retrofit2:retrofit:2.x.x'
implementation 'com.squareup.retrofit2:converter-gson:2.x.x'

public class User {
    private String name;
    private int age;

    // 构造函数、Getter和Setter方法
}

public interface ApiService {
    @POST("/users")
    Call<Void> postUsers(@Body List<User> users);
}

Retrofit retrofit = new Retrofit.Builder()
        .baseUrl("http://your-server-url.com")
        .addConverterFactory(GsonConverterFactory.create())
        .build();

ApiService apiService = retrofit.create(ApiService.class);

List<User> users = new ArrayList<>();
users.add(new User("John", 25));
users.add(new User("Jane", 30));

Call<Void> call = apiService.postUsers(users);
call.enqueue(new Callback<Void>() {
    @Override
    public void onResponse(Call<Void> call, Response<Void> response) {
        if (response.isSuccessful()) {
            // 请求成功处理
        } else {
            // 请求失败处理
        }
    }

    @Override
    public void onFailure(Call<Void> call, Throwable t) {
        // 请求失败处理
    }
});
