Загрузка изображения с использованием okHttp

Ответ 1

Вам нужно использовать

new MultipartBody.Builder()

Вместо

new MultipartBuilder()

Работает

Ответ 2

Вот класс запроса нескольких частей.

    this.caller = caller;
    this.builder = new MultipartBuilder();
    this.builder.type(MultipartBuilder.FORM);
    this.client = new OkHttpClient();

public void addString(String name, String value) {
    this.builder.addFormDataPart(name, value);
}

public void addFile(String name, String filePath, String fileName) {
    this.builder.addFormDataPart(name, fileName, RequestBody.create(
            MediaType.parse("image/jpeg"), new File(filePath)));
}

public void addTXTFile(String name, String filePath, String fileName) {
    this.builder.addFormDataPart(name, fileName, RequestBody.create(
            MediaType.parse("text/plain"), new File(filePath)));
}

public void addZipFile(String name, String filePath, String fileName)
{
    this.builder.addFormDataPart(name, fileName, RequestBody.create(
           MediaType.parse("application/zip"), new File(filePath)));
}

public String execute(String url) {
    RequestBody requestBody = null;
    Request request = null;
    Response response = null;

    int code = 200;
    String strResponse = null;

    try {
        requestBody = this.builder.build();
        request = new Request.Builder().header("AUTH-KEY", Config.API_KEY)
                .url(url).post(requestBody).build();

        Log.print("::::::: REQ :: " + request);
        response = client.newCall(request).execute();
        Log.print("::::::: response :: " + response);

        if (!response.isSuccessful())
            throw new IOException();

        code = response.networkResponse().code();

        if (response.isSuccessful()) {
            strResponse = response.body().string();
        } else if (code == HttpStatus.SC_NOT_FOUND) {
            // ** "Invalid URL or Server not available, please try again" */
            strResponse = caller.getResources().getString(
                    R.string.error_invalid_URL);
        } else if (code == HttpStatus.SC_REQUEST_TIMEOUT) {
            // * "Connection timeout, please try again", */
            strResponse = caller.getResources().getString(
                    R.string.error_timeout);
        } else if (code == HttpStatus.SC_SERVICE_UNAVAILABLE) {
            // *
            // "Invalid URL or Server is not responding, please try again",
            // */
            strResponse = caller.getResources().getString(
                    R.string.error_server_not_responding);
        }
    } catch (Exception e) {
        Log.error("Exception", e);
        Log.print(e);
    } finally {
        requestBody = null;
        request = null;
        response = null;
        builder = null;
        if (client != null)
            client = null;
        System.gc();
    }
    return strResponse;
  }
}

Надеюсь, что это поможет вам.

Примечание. Если вы используете старый OkHttp, который ниже версии 3, вы можете использовать этот метод. Если вы используете версию 3 или выше здесь ответьте на вопрос.

Ответ 3

Я использовал этот способ в OKHTTP 3.4.1

Функция вызова, подобная этой

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

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();
