Przesyłanie obrazów za pomocą okHttp

Question

Chcę przesłać obraz za pomocą okhttp, ale nie mogę znaleźć MultipartBuilder dla Post Image. Co mogę zamiast tego użyć.

Oto mój kod

public static JSONObject uploadImage(File file) { 

     try { 

      final MediaType MEDIA_TYPE_PNG = MediaType.parse("image/png"); 

      RequestBody req = new MultipartBuilder().setType(MultipartBody.FORM).addFormDataPart("userid", "8457851245") 
        .addFormDataPart("userfile","profile.png", RequestBody.create(MEDIA_TYPE_PNG, file)).build(); 

      Request request = new Request.Builder() 
        .url("url") 
        .post(req) 
        .build(); 

      OkHttpClient client = new OkHttpClient(); 
      Response response = client.newCall(request).execute(); 

      Log.d("response", "uploadImage:"+response.body().string()); 

      return new JSONObject(response.body().string()); 

     } catch (UnknownHostException | UnsupportedEncodingException e) { 
      Log.e(TAG, "Error: " + e.getLocalizedMessage()); 
     } catch (Exception e) { 
      Log.e(TAG, "Other Error: " + e.getLocalizedMessage()); 
     } 
     return null; 
    } 

góry dzięki.

trzeba użyć

Multipartbody.Builder() 

Zamiast

Oto klasa żądań wieloczęściowych.

Mam nadzieję, że ci to pomoże.

Uwaga: Jeśli używasz starego OkHttp poniżej wersji 3, możesz użyć tej metody.Jeśli używasz wersji 3 lub wyższej here is the answer for you.

Answer 3

Kiedyś tędy w OKHTTP 3.4.1

funkcja połączeń jak to

if (!realPath.equals("")) { 

      new SignupWithImageTask().execute(et_name.getText().toString(), et_email.getText().toString(), et_dob.getText().toString(), IMEI, et_mobile.getText().toString(), realPath); 

     } else { 
      Toast.makeText(this, "Profile Picture not found", Toast.LENGTH_SHORT).show(); 
     } 

SignupWithImageTask

public class SignupWithImageTask extends AsyncTask<String, Integer, String> { 

     ProgressDialog progressDialog; 

     @Override 
     protected void onPreExecute() { 
      super.onPreExecute(); 
      progressDialog = new ProgressDialog(SignupActivity.this); 
      progressDialog.setMessage("Please Wait...."); 
      progressDialog.show(); 
     } 

     @Override 
     protected String doInBackground(String... str) { 

      String res = null; 
      try { 
//    String ImagePath = str[0]; 
       String name = str[0], email = str[1], dob = str[2], IMEI = str[3], phone = str[4], ImagePath = str[5]; 

       File sourceFile = new File(ImagePath); 

       Log.d("TAG", "File...::::" + sourceFile + " : " + sourceFile.exists()); 

       final MediaType MEDIA_TYPE_PNG = MediaType.parse("image/*"); 

       String filename = ImagePath.substring(ImagePath.lastIndexOf("/") + 1); 

       /** 
       * OKHTTP2 
       */ 
//   RequestBody requestBody = new MultipartBuilder() 
//     .type(MultipartBuilder.FORM)

       RequestBody requestBody = new MultipartBody.Builder() 
         .setType(MultipartBody.FORM) 
         .addFormDataPart("image", filename, RequestBody.create(MEDIA_TYPE_PNG, sourceFile)) 
         .addFormDataPart("result", "my_image") 
         .addFormDataPart("name", name) 
         .addFormDataPart("email", email) 
         .addFormDataPart("dob", dob) 
         .addFormDataPart("IMEI", IMEI) 
         .addFormDataPart("phone", phone) 
         .build(); 

       Request request = new Request.Builder() 
         .url(BASE_URL + "signup") 
         .post(requestBody) 
         .build(); 

       OkHttpClient client = new OkHttpClient(); 
       okhttp3.Response response = client.newCall(request).execute(); 
       res = response.body().string(); 
       Log.e("TAG", "Response : " + res); 
       return res; 

      } catch (UnknownHostException | UnsupportedEncodingException e) { 
       Log.e("TAG", "Error: " + e.getLocalizedMessage()); 
      } catch (Exception e) { 
       Log.e("TAG", "Other Error: " + e.getLocalizedMessage()); 
      } 


      return res; 

     } 

     @Override 
     protected void onPostExecute(String response) { 
      super.onPostExecute(response); 
      if (progressDialog != null) 
       progressDialog.dismiss(); 

      if (response != null) { 
       try { 

        JSONObject jsonObject = new JSONObject(response); 


        if (jsonObject.getString("message").equals("success")) { 

         JSONObject jsonObject1 = jsonObject.getJSONObject("data"); 

         SharedPreferences settings = getSharedPreferences("preference", 0); // 0 - for private mode 
         SharedPreferences.Editor editor = settings.edit(); 
         editor.putString("name", jsonObject1.getString("name")); 
         editor.putString("userid", jsonObject1.getString("id")); 
         editor.putBoolean("hasLoggedIn", true); 
         editor.apply(); 

         new UploadContactTask().execute(); 

         startActivity(new Intent(SignupActivity.this, MainActivity.class)); 
        } else { 
         Toast.makeText(SignupActivity.this, "" + jsonObject.getString("message"), Toast.LENGTH_SHORT).show(); 
        } 
       } catch (JSONException e) { 
        e.printStackTrace(); 
       } 
      } else { 
       Toast.makeText(SignupActivity.this, "Something Went Wrong", Toast.LENGTH_SHORT).show(); 
      } 

     } 
    } 

Answer 4

OkHttpClient client = new OkHttpClient.Builder().connectTimeout(10, TimeUnit.SECONDS).writeTimeout(180, TimeUnit.SECONDS).readTimeout(180, TimeUnit.SECONDS).build(); 
    RequestBody body = new MultipartBody.Builder().setType(MultipartBody.FORM) 
      .addFormDataPart("File", path.getName(),RequestBody.create(MediaType.parse("application/vnd.openxmlformats-officedocument.spreadsheetml.sheet"),path)) 
      .addFormDataPart("username", username) 
      .addFormDataPart("password", password) 
      .build(); 
    Request request = new Request.Builder().url(url).post(body).build(); 
    Response response = client.newCall(request).execute(); 
    result = response.body().string();
