Tải lên hình ảnh bằng cách sử dụng okHttp

Question

tôi muốn tải lên hình ảnh bằng cách sử dụng okhttp nhưng tôi không thể tìm thấy MultipartBuilder cho Hình ảnh Bài đăng. Tôi có thể sử dụng thay vì điều này.

Đây là mã của tôi

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; 
    } 

Cảm ơn trước.

Answer 1

Bạn cần phải sử dụng

Multipartbody.Builder() 

Thay vì

MultipartBuilder 

của nó làm việc

Hy vọng điều này sẽ giúp bạn.

Lưu ý: Nếu bạn đang sử dụng OkHttp cũ dưới phiên bản 3 thì bạn có thể sử dụng phương pháp này.Nếu bạn đang sử dụng phiên bản 3 hoặc cao hơn here is the answer for you.

Answer 3

tôi đã sử dụng cách này trong OKHTTP 3.4.1

Gọi chức năng như

này

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)

       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;

      } 


      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) {

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();
