如何在翻新中发送json格式参数的请求参数

Interface--
public interface ApiPhotoInterface {
    @Headers("Content-Type: application/json")
    @POST("photo/re/v7")
    Call<PhotoModel> getResponse(@Body ParamModel paramModel);
}

//This is the Interface class  

MainClass.java-- 在主要班级

ApiPhotoInterface apiInterface = ApiPhotoClient.getApi();
 Call<ParamModel> call = apiInterface.getResponse();

如何在getResponse方法中设置参数？

这是客户端类，其中提到了基本URL和接口

public class ApiPhotoClient {

    private static final String BASE_URL = "  https://services.something.com/api/";

    private static ApiPhotoInterface apiInterface;

    public static ApiPhotoInterface getApi() {
        if (apiInterface == null) {
            apiInterface = new Retrofit.Builder()
                    .baseUrl(BASE_URL)
                    .addConverterFactory(GsonConverterFactory.create())
                    .build()
                    .create(ApiPhotoInterface.class);
        }
        return apiInterface;
    }
}



2 param models--
public class ParamModel {

    @SerializedName("Key")
    @Expose
    private String apiKey;
    @SerializedName("affId")
    @Expose
    private String affId;
    @SerializedName("act")
    @Expose
    private String act;
    @SerializedName("latitude")
    @Expose
    private String latitude;
    @SerializedName("longitude")
    @Expose
    private String longitude;
    @SerializedName("devinf")
    @Expose
    private String devinf;
    @SerializedName("app")
    @Expose
    private String appver;
    @SerializedName("Details")
    @Expose
    private List<ParamDetailModel> Details = null;

    public String getApiKey() {
        return apiKey;
    }

    public void setApiKey(String apiKey) {
        this.apiKey = apiKey;
    }

    public String getAffId() {
        return affId;
    }

    public void setAffId(String affId) {
        this.affId = affId;
    }

    public String getAct() {
        return act;
    }

    public void setAct(String act) {
        this.act = act;
    }

    public String getLatitude() {
        return latitude;
    }

    public void setLatitude(String latitude) {
        this.latitude = latitude;
    }

    public String getLongitude() {
        return longitude;
    }

    public void setLongitude(String longitude) {
        this.longitude = longitude;
    }

    public String getDevinf() {
        return devinf;
    }

    public void setDevinf(String devinf) {
        this.devinf = devinf;
    }

    public String getAppver() {
        return appver;
    }

    public void setAppver(String appver) {
        this.appver = appver;
    }

    public List<ParamProductDetailModel> getProductDetails() {
        return productDetails;
    }

    public void setProductDetails(List<ParamProductDetailModel> productDetails) {
        this.productDetails = productDetails;
    }

}




public class ParamProductDetailModel  {

    @SerializedName("productId")
    @Expose
    private String productId;
    @SerializedName("qty")
    @Expose
    private String qty;

    public String getProductId() {
        return productId;
    }

    public void setProductId(String productId) {
        this.productId = productId;
    }

    public String getQty() {
        return qty;
    }

    public void setQty(String qty) {
        this.qty = qty;
    }

}

如何在.getResponse（）中设置参数？ 问题是如何在活动类的getResponse中发送请求参数。
