怎么做？使用Retrofit2将当前日期从Android插入mySQL数据库

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

public class DateModel {
    @SerializedName("date")
    private String date;

    public DateModel(String date) {
        this.date = date;
    }

    public String getDate() {
        return date;
    }
}

public interface ApiService {
    @POST("insert_date")
    Call<Void> insertDate(@Body DateModel dateModel);
}

// 创建Retrofit实例
Retrofit retrofit = new Retrofit.Builder()
        .baseUrl("http://example.com/api/")
        .addConverterFactory(GsonConverterFactory.create())
        .build();

// 创建API服务实例
ApiService apiService = retrofit.create(ApiService.class);

// 获取当前日期
SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd");
String currentDate = sdf.format(new Date());

// 创建日期模型对象
DateModel dateModel = new DateModel(currentDate);

// 发送插入日期的请求
Call<Void> call = apiService.insertDate(dateModel);
call.enqueue(new Callback<Void>() {
    @Override
    public void onResponse(Call<Void> call, Response<Void> response) {
        if (response.isSuccessful()) {
            // 插入成功
        } else {
            // 插入失败
        }
    }

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