Comment télécharger un fichier image dans Retrofit 2

J'ai une image de postier comme ci-dessous. Comment faire la même chose dans Retrofit 2. enter image description here

J'ai déclaré l'interface comme ceci.

@Multipart
@POST("/api/Pharmarcy/UploadImage")
Call<ResponseBody> uploadPrescriptionImage(
        @Query("accessToken") String token,
        @Query("pharmarcyRequestId") int pharmacyRequestedId,
        @Part MultipartBody.Part image);

@Multipart
@POST("user/updateprofile")
Observable<ResponseBody> updateProfile(@Part("user_id") RequestBody id,
                                       @Part("full_name") RequestBody fullName,
                                       @Part MultipartBody.Part image,
                                       @Part("other") RequestBody other);

//pass it like this
File file = new File("/storage/emulated/0/Download/Corrections 6.jpg");
RequestBody requestFile =
        RequestBody.create(MediaType.parse("multipart/form-data"), file);

// MultipartBody.Part is used to send also the actual file name
MultipartBody.Part body =
        MultipartBody.Part.createFormData("image", file.getName(), requestFile);

// add another part within the multipart request
RequestBody fullName = 
        RequestBody.create(MediaType.parse("multipart/form-data"), "Your Name");

service.updateProfile(id, fullName, body, other);

Regardez la façon dont je passe les paramètres multipart et string. J'espère que cela vous aidera!

En utilisant Retrofit 2.0, vous pouvez utiliser ceci:

@Multipart
    @POST("uploadImage")
    Call<ResponseBody> uploadImage(@Part("file\"; fileName=\"myFile.png\" ")RequestBody requestBodyFile, @Part("image") RequestBody requestBodyJson);

Faire une demande:

File imgFile = new File("YOUR IMAGE FILE PATH");
RequestBody requestBodyFile = RequestBody.create(MediaType.parse("image/*"), imgFile);
RequestBody requestBodyJson = RequestBody.create(MediaType.parse("text/plain"),
                    retrofitClient.getJsonObject(uploadRequest));



//make sync call
Call<ResponseBody> uploadBundle = uploadImpl.uploadImage(requestBodyFile, requestBodyJson);
Response<BaseResponse> response = uploadBundle.execute();

@Multipart
@POST(Config.UPLOAD_IMAGE)
Observable<Response<String>> uploadPhoto(@Header("Access-Token") String header, @Part MultipartBody.Part imageFile);

Et vous pouvez appeler cette api comme ceci:

   public void uploadImage(File file) {
     // create multipart
     RequestBody requestFile = RequestBody.create(MediaType.parse("multipart/form-data"), file);
    MultipartBody.Part body = MultipartBody.Part.createFormData("image", file.getName(), requestFile);

    // upload
    getViewInteractor().showProfileUploadingProgress();

    Observable<Response<String>> observable = api.uploadPhoto("",body);

    // on Response
    subscribeForNetwork(observable, new ApiObserver<Response<String>>() {
        @Override
        public void onError(Throwable e) {
            getViewInteractor().hideProfileUploadingProgress();
        }

        @Override
        public void onResponse(Response<String> response) {

            if (response.code() != 200) {
                Timber.d("error " + response.code());
                return;
            }
            getViewInteractor().hideProfileUploadingProgress();
            getViewInteractor().onProfileImageUploadSuccess(response.body());

        }
    });

}

C'est assez facile. Voici l'interface API

public interface Api {

    @Multipart
    @POST("upload")
    Call<MyResponse> uploadImage(@Part("image\"; filename=\"myfile.jpg\" ") RequestBody file, @Part("desc") RequestBody desc);

}

Et vous pouvez utiliser le code suivant pour effectuer un appel.

private void uploadFile(File file, String desc) {

        //creating request body for file
        RequestBody requestFile = RequestBody.create(MediaType.parse(getContentResolver().getType(fileUri)), file);
        RequestBody descBody = RequestBody.create(MediaType.parse("text/plain"), desc);

        //The gson builder
        Gson gson = new GsonBuilder()
                .setLenient()
                .create();


        //creating retrofit object
        Retrofit retrofit = new Retrofit.Builder()
                .baseUrl(Api.BASE_URL)
                .addConverterFactory(GsonConverterFactory.create(gson))
                .build();

        //creating our api 
        Api api = retrofit.create(Api.class);

        //creating a call and calling the upload image method 
        Call<MyResponse> call = api.uploadImage(requestFile, descBody);

        //finally performing the call 
        call.enqueue(new Callback<MyResponse>() {
            @Override
            public void onResponse(Call<MyResponse> call, Response<MyResponse> response) {
                if (!response.body().error) {
                    Toast.makeText(getApplicationContext(), "File Uploaded Successfully...", Toast.LENGTH_LONG).show();
                } else {
                    Toast.makeText(getApplicationContext(), "Some error occurred...", Toast.LENGTH_LONG).show();
                }
            }

            @Override
            public void onFailure(Call<MyResponse> call, Throwable t) {
                Toast.makeText(getApplicationContext(), t.getMessage(), Toast.LENGTH_LONG).show();
            }
        });
    }

Totalement d'accord avec @ tir38 et @Android_griezmann. Ce serait la version en kotlin:

interface servicesEndPoint {
@Multipart
@POST("user/updateprofile")
fun updateProfile(@Part("user_id") id:RequestBody, @Part("full_name") other:fullName, @Part image: MultipartBody.Part, @Part("other") other:RequestBody): Single<UploadPhotoResponse>

companion object {
        val API_BASE_URL = "YOUR_URL"

        fun create(): servicesPhotoEndPoint {
            val retrofit = Retrofit.Builder()
                .addCallAdapterFactory(RxJava2CallAdapterFactory.create())
                .addConverterFactory(GsonConverterFactory.create())
                .baseUrl(API_BASE_URL)
                .build()
            return retrofit.create(servicesPhotoEndPoint::class.Java)
        }
    }
}

// pass it like this
val file = File(RealPathUtils.getRealPathFromURI_API19(context, uri))  
val requestFile: RequestBody = RequestBody.create(MediaType.parse("multipart/form-data"), file)

// MultipartBody.Part is used to send also the actual file name
val body: MultipartBody.Part = MultipartBody.Part.createFormData("image", file.name, requestFile)

// add another part within the multipart request
val fullName: RequestBody = RequestBody.create(MediaType.parse("multipart/form-data"), "Your Name")

servicesEndPoint.create().updateProfile(id, fullName, body, fullName)

Pour obtenir le chemin réel, utilisez RealPathUtils. Vérifiez cette classe dans les réponses de @Harsh Bhavsar à cette question: Comment obtenir le chemin d'accès complet à l'URI .

Pour getRealPathFromURI_API19, vous devez avoir les autorisations de READ_EXTERNAL_STORAGE.

Solution Retrofit 2.0

@Multipart
@POST(APIUtils.UPDATE_PROFILE_IMAGE_URL)
public Call<CommonResponse> requestUpdateImage(@PartMap Map<String, RequestBody> map);

et

    Map<String, RequestBody> params = new HashMap<>();

    params.put("newProfilePicture" + "\"; filename=\"" + FilenameUtils.getName(file.getAbsolutePath()), RequestBody.create(MediaType.parse("image/jpg"), file));



 Call<CommonResponse> call = request.requestUpdateImage(params);

vous pouvez utiliser
image/jpg image/png image/gif
