android - studio - Cómo subir un archivo de imagen en Retrofit 2

retrofit2 http get

Question

Tengo una imagen de cartero como abajo. Cómo hacer lo mismo en Retrofit 2.

He declarado la interfaz como esta.

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

Answer 1

Es bastante facil Aquí está la interfaz API

public interface Api {
@Multipart
@POST("upload")
Call<MyResponse> uploadImage(@Part("image/"; filename=/"myfile.jpg/" ") RequestBody file, @Part("desc") RequestBody desc);
}

Y puedes usar el siguiente código para hacer una llamada.

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();
}
});
}

Answer 2

Usando Retrofit 2.0 puedes usar esto:

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

Hacer una solicitud:

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("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);

Mira la forma en que estoy pasando los parámetros multiparte y cadena. ¡Espero que esto te ayudará!

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

Y puedes llamar a esta api así:

 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());
}
});
}
