Ho usato Retrofit 2.0 per i miei utenti registrati, invio immagine e testo di file multipart / form dall'account del registro
Nel mio RegisterActivity, utilizzare un AsyncTask
//AsyncTask
private class Register extends AsyncTask<String, Void, String> {
@Override
protected void onPreExecute() {..}
@Override
protected String doInBackground(String... params) {
new com.tequilasoft.mesasderegalos.dbo.Register().register(txtNombres, selectedImagePath, txtEmail, txtPassword);
responseMensaje = StaticValues.mensaje ;
mensajeCodigo = StaticValues.mensajeCodigo;
return String.valueOf(StaticValues.code);
}
@Override
protected void onPostExecute(String codeResult) {..}
E nella mia classe Register.java è dove utilizzare Retrofit con chiamata sincrona
import android.util.Log;
import com.tequilasoft.mesasderegalos.interfaces.RegisterService;
import com.tequilasoft.mesasderegalos.utils.StaticValues;
import com.tequilasoft.mesasderegalos.utils.Utilities;
import java.io.File;
import okhttp3.MediaType;
import okhttp3.MultipartBody;
import okhttp3.RequestBody;
import okhttp3.ResponseBody;
import retrofit2.Call;
import retrofit2.Response;
/**Created by sam on 2/09/16.*/
public class Register {
public void register(String nombres, String selectedImagePath, String email, String password){
try {
// create upload service client
RegisterService service = ServiceGenerator.createUser(RegisterService.class);
// add another part within the multipart request
RequestBody requestEmail =
RequestBody.create(
MediaType.parse("multipart/form-data"), email);
// add another part within the multipart request
RequestBody requestPassword =
RequestBody.create(
MediaType.parse("multipart/form-data"), password);
// add another part within the multipart request
RequestBody requestNombres =
RequestBody.create(
MediaType.parse("multipart/form-data"), nombres);
MultipartBody.Part imagenPerfil = null;
if(selectedImagePath!=null){
File file = new File(selectedImagePath);
Log.i("Register","Nombre del archivo "+file.getName());
// create RequestBody instance from file
RequestBody requestFile =
RequestBody.create(MediaType.parse("multipart/form-data"), file);
// MultipartBody.Part is used to send also the actual file name
imagenPerfil = MultipartBody.Part.createFormData("imagenPerfil", file.getName(), requestFile);
}
// finally, execute the request
Call<ResponseBody> call = service.registerUser(imagenPerfil, requestEmail,requestPassword,requestNombres);
Response<ResponseBody> bodyResponse = call.execute();
StaticValues.code = bodyResponse.code();
StaticValues.mensaje = bodyResponse.message();
ResponseBody errorBody = bodyResponse.errorBody();
StaticValues.mensajeCodigo = errorBody==null
?null
:Utilities.mensajeCodigoDeLaRespuestaJSON(bodyResponse.errorBody().byteStream());
Log.i("Register","Code "+StaticValues.code);
Log.i("Register","mensaje "+StaticValues.mensaje);
Log.i("Register","mensajeCodigo "+StaticValues.mensaje);
}
catch (Exception e){
e.printStackTrace();
}
}
}
Nell'interfaccia di RegisterService
public interface RegisterService {
@Multipart
@POST(StaticValues.REGISTER)
Call<ResponseBody> registerUser(@Part MultipartBody.Part image,
@Part("email") RequestBody email,
@Part("password") RequestBody password,
@Part("nombre") RequestBody nombre
);
}
Per l'analisi delle utilità della risposta InputStream
public class Utilities {
public static String mensajeCodigoDeLaRespuestaJSON(InputStream inputStream){
String mensajeCodigo = null;
try {
BufferedReader reader = new BufferedReader(
new InputStreamReader(
inputStream, "iso-8859-1"), 8);
StringBuilder sb = new StringBuilder();
String line;
while ((line = reader.readLine()) != null) {
sb.append(line).append("\n");
}
inputStream.close();
mensajeCodigo = sb.toString();
} catch (Exception e) {
Log.e("Buffer Error", "Error converting result " + e.toString());
}
return mensajeCodigo;
}
}
