Send Form Data To Server In Retrofit

Trying to send form data to the server via Retrofit but unable to request to the server. I want to post an image array with their data. val builder: MultipartBody.Builder = Multipa

Solution 1:

Dummy api interface.

publicinterfaceApiInterface {
        @Multipart@POST(URLHelper.register)
        Call<ModelProp> signUp2(@Part List<MultipartBody.Part> photos,
                          @PartMap Map<String, RequestBody> map;
    }

Now create data to post like this.

Map<String, RequestBody> partMap = new HashMap<>();
List<MultipartBody.Part> images = new ArrayList<>();
partMap.put("device_id", createPartFromString(deviceId)); // add data which are common for all images like device_id, device_token, device_type etc.
..
..

for (int i=0; i < upFileList.size(); i++){
   images.add(prepareFilePart("provider_documents["+i+"][document]", imageFile));
   partMap.add("provider_documents["+i+"][expires_at]", createPartFromString(expiry)); // add image specific data. 
 ...
 ..
}
...
..
observable = apiInterface.signUp2(images, partMap).

createPartFromString method

publicRequestBodycreatePartFromString(Stringstring) {
        returnRequestBody.create(MultipartBody.FORM, string);
}

prepareFilePart method

privateMultipartBody.PartprepareFilePart(String partName, File file){
    RequestBody requestBody = RequestBody.create(MediaType.parse("image/*"), file);

    returnMultipartBody.Part.createFormData(partName, file.getName(),requestBody);
}

Solution 2:

Use it Like this:-

// @Multipart@POST(URLHelper.register)
fun signUp2(@Partbuilder: MultipartBody ): Observable<Registration>

Updated :-

privatevoiduploadToServer(String filePath) {
        showProgressDialog();
        Retrofitretrofit= RetrofitClient.getRetrofitClient(this);
        ApiInterfaceuploadAPIs= retrofit.create(ApiInterface.class);
        Filefile=newFile(filePath);
        //compressor.setDestinationDirectoryPath()RequestBodyfileReqBody= RequestBody.create(MediaType.parse("image/*"), file);
        MultipartBody.Partpart= MultipartBody.Part.createFormData("fileUpload", file.getName(), fileReqBody);
        //RequestBody description = RequestBody.create(MediaType.parse("text/plain"), "image-type");RequestBodyimgNameReqBody= RequestBody.create(MediaType.parse("multipart/form-data"), "B2B_" + System.nanoTime());

        uploadAPIs.uploadImage(imgNameReqBody, part).enqueue(newCallback<UploadImageRespose>() {
            @OverridepublicvoidonResponse(@NonNull Call<UploadImageRespose> call, @NonNull retrofit2.Response<UploadImageRespose> response) {
                if (response.isSuccessful() && response.body() != null) {
                    if (response.body().getCODE().equalsIgnoreCase("SUCCESS")) {
                        Toast.makeText(Activity.this, "Profile Image Upload Succesfully", Toast.LENGTH_SHORT).show();
                    } else {
                        hideProgressDialog();
                        Toast.makeText(Activity.this, "Some Error  occurred, try again", Toast.LENGTH_SHORT).show();
                    }
                } else {
                    hideProgressDialog();
                }

            }

            @OverridepublicvoidonFailure(@NonNull Call<UploadImageRespose> call, @NonNull Throwable t) {
                Timber.d(TAG, t.getMessage());
                hideProgressDialog();
                Toast.makeText(Activity.this, "Some Error  occurred, try again", Toast.LENGTH_SHORT).show();
            }
        });
    }

add below method in your interface:-

@Multipart@POST("Your Path Here")
    Call<UploadImageRespose> uploadImage(@Part("img_name") RequestBody img_name,
                                         @Part MultipartBody.Part file);
