Я пытаюсь отправить изображение (после захвата) на сервер с помощью мобильного телефона (android). Для этого я использую php-скрипт (его загружается на сервер) и код JAVA для отправки изображения.
URL-адрес php-скрипта: http://nwstudio.esy.es/AndroidFileUpload/uploads/fileUpload.php
На мобильном устройстве после нажатия кнопки для загрузки я вижу только небольшое пустое окно без текста ошибки или чего-то еще (должен быть msg о загрузке)
Что я делаю неправильно? ; /
PHP:
<?php // Path to move uploaded files $target_path = "uploads/"; // array for final json respone $response = array(); // getting server ip address $server_ip = gethostbyname(gethostname()); // final file url that is being uploaded $file_upload_url = 'http://' . $server_ip . '/' . 'AndroidFileUpload' . '/' . $target_path; if (isset($_FILES['image']['name'])) { $target_path = $target_path . basename($_FILES['image']['name']); // reading other post parameters $email = isset($_POST['email']) ? $_POST['email'] : ''; $website = isset($_POST['website']) ? $_POST['website'] : ''; $response['file_name'] = basename($_FILES['image']['name']); $response['email'] = $email; $response['website'] = $website; try { // Throws exception incase file is not being moved if (!move_uploaded_file($_FILES['image']['tmp_name'], $target_path)) { // make error flag true $response['error'] = true; $response['message'] = 'Could not move the file!'; } // File successfully uploaded $response['message'] = 'File uploaded successfully!'; $response['error'] = false; $response['file_path'] = $file_upload_url . basename($_FILES['image']['name']); } catch (Exception $e) { // Exception occurred. Make error flag true $response['error'] = true; $response['message'] = $e->getMessage(); } } else { // File parameter is missing $response['error'] = true; $response['message'] = 'Not received any file!F'; } // Echo final json response to client echo json_encode($response); ?>

Конфигурация JAVA:
package com.nkdroid.tinderswipe; /** * Created by Haze on 15.08.2016. */ public class Config { // File upload url (replace the ip with your server address) public static final String FILE_UPLOAD_URL = "http://http://nwstudio.esy.es/AndroidFileUpload/uploads/fileUpload.php"; // Directory name to store captured images and videos public static final String IMAGE_DIRECTORY_NAME = "AndroidFileUpload"; }
Я рекомендую вам не использовать AsyncTask для этой цели. Вместо AsyncTask попробуйте отправить изображение с помощью Retrofit 2
ОБНОВИТЬ
Это мой проект Retrofit2Sample, который показывает использование Retrofit 2 . Я считаю, что это поможет понять, как это работает и показать, как работать с этим удивительным клиентом отдыха.
