How to set request params for json type params in a call from MainActivity?

This is my Interface class in which there is headers annotation of type application/json and using the post method and use call in which using body annotation having a model for param request

public interface ApiStorePhotoInterface {
        @Headers("Content-Type: application/json")
        @POST("photo/st/v7")
        Call<PhotoStoreMainModel> getResponse(@Body ParamModel paramModel);
    }

Here ParamModel is json model and Use this for call.

2 Param Models for @Body in Interface- This Model contains values with the List in which ParamProductDetailModel is the second model in it. 1st Param Model -

public class ParamModel {

    @SerializedName("apiKey")
    @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("appver")
    @Expose
    private String appver;
    @SerializedName("productDetails")
    @Expose
    private List<ParamProductDetailModel> productDetails = 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;
    }

}

2nd Param Model -

 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;
    }

}

This is the client class

Client class-

This is the retrofit builder class

public class ApiStorePhotoClient {

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

    private static ApiStorePhotoInterface apiInterface;

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

Now, in my Main class-

ApiStorePhotoInterface apiInterface = ApiStorePhotoClient.getApi();

Call<PhotoStoreMainModel> call = apiInterface.getResponse("What to write here??");

How to send Request inside the model in getResponse()?

PhotoStoreMainModel is the response model. The code has 3 response model in which the PhotoStoreMainModel is one of them and 2 request params model which is posted above.

How to send request params in @body ParamModel inside Mainclass in getResponse()?

How to set lines for a call in my MainActivity class?

I Expect the result but not able to hit the API due to request params

Answer 1

You can add arrayObjects like this, after update you can check your request with Log.:

        JsonObject jsonObject1 = new JsonObject();
        jsonObject1.addProperty("apiKey", "wseoagbiis5dd6vq5tfbs3r1c8rsz");
        jsonObject1.addProperty("appver", "1.00");
        jsonObject1.addProperty("affid", "team");

        Global.printLog("jsonObject1", "===" + jsonObject1);

        JsonArray productDetail1Array = new JsonArray();

        for (int i1 = 0; i1 < 1; i1++) {
            JsonObject productDetail1 = new JsonObject();
            productDetail1.addProperty("productId", "6670002");

            JsonArray array1 = new JsonArray();

            for (int j = 0; j < 2; j++) {
                JsonObject imageDetails = new JsonObject();

                imageDetails.addProperty("qty", j + "");
                imageDetails.addProperty("url", "something.com/assets_admin/uploads/frame_image/…");
                array1.add(imageDetails);
            }

            productDetail1.add("imageDetails", array1);

            productDetail1Array.add(productDetail1);

        }
        jsonObject1.add("productDetails", productDetail1Array);

        Global.printLog("jsonObject1", "===" + jsonObject1);

You can pass your object like this:

 JSONObject jsonObject = new JSONObject();
   try {
     jsonObject.put("key1", "value1");
     jsonObject.put("key2", value2);

     JsonParser jsonParser = new JsonParser();

    ApiStorePhotoInterface apiInterface = ApiStorePhotoClient.getApi();

    **Call<PhotoStoreMainModel> call = apiInterface.getResponse((JsonObject) jsonParser.parse(jsonObject.toString()));  //This is not the correct way to parse the json. Not getting correct hit** 

    call.enqueue(new Callback<PhotoStoreMainModel>() {
                @Override
                public void onResponse(Call<PhotoStoreMainModel> call, Response<PhotoStoreMainModel> response) {
                 }

                @Override
                public void onFailure(Call<PhotoStoreMainModel> call, Throwable t) {
                    call.cancel();
                    t.printStackTrace();
                }
            });

    } catch (JSONException e) {
            e.printStackTrace();
    }

Answer 2

No need to add content type

Change your interface like

public interface ApiStorePhotoInterface {


        @POST("photo/st/v7")
        Call<PhotoStoreMainModel> getResponse(@Body JsonObject obj);
    }

Make json object like:

JsonObject json = new JsonObject();
json.addProperty("affId", id_value)

// like above all params

pass the above in object in getResponse
