Java — Android Загрузить изображение с помощью MultipartEntity с помощью GDK
Я разрабатываю приложение для google glass с помощью GDK, и я пытаюсь загрузить свое захваченное изображение с помощью MultiPartEntity, но я не могу заставить его работать по какой-то причине, я не могу понять, потому что он не возвращает никакой ошибки. На данный момент это то, где я нахожусь.

String picturePath = data.getStringExtra(Intents.EXTRA_PICTURE_FILE_PATH);
final File pictureFile = new File(picturePath);
HttpClient httpclient = new DefaultHttpClient();
HttpPost httppost = new HttpPost("SERVER PATH");
try {
@SuppressWarnings("deprecation")
MultipartEntity entity = new MultipartEntity();
entity.addPart("type", new StringBody("photo"));
entity.addPart("data", new FileBody(pictureFile));
httppost.setEntity(entity);
HttpResponse response = httpclient.execute(httppost);
} catch (ClientProtocolException e) {
} catch (IOException e) {
}
PHP-код:
$response = array();
$file_upload_url = 'UPLOAD PATH';if (isset($_FILES['image']['name'])) {
$target_path = $target_path . basename($_FILES['image']['name']);
$email = isset($_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;
$response['message'] = 'Not received any file!';
}
echo json_encode($response);
?>
Любая помощь приветствуется.
Решение
Это мой код это работает для меня. С помощью этого кода вы можете отправлять параметры и файлы с индикатором выполнения.
public class SendFile extends AsyncTask<String, Integer, Integer> {
private Context conT;
private ProgressDialog dialog;
private String SendUrl = "";
private String SendFile = "";
private String Parameters = "";
private String result;
public File file;
SendFile(Context activity, String url, String filePath, String values) {
conT = activity;
dialog = new ProgressDialog(conT);
SendUrl = url;
SendFile = filePath;
Parameters = Values;
}
@Override
protected void onPreExecute() {
file = new File(SendFile);
dialog.setMessage("Please Wait..");
dialog.setCancelable(false);
dialog.setProgressStyle(ProgressDialog.STYLE_HORIZONTAL);
dialog.setMax((int) file.length());
dialog.show();
}
@Override
protected Integer doInBackground(String... params) {
HttpURLConnection connection = null;
DataOutputStream outputStream = null;
InputStream inputStream = null;
String twoHyphens = "--";
String boundary = "*****"+ Long.toString(System.currentTimeMillis()) + "*****";
String lineEnd = "\r\n";
int bytesRead, bytesAvailable, bufferSize;
byte[] buffer;
int maxBufferSize = 1 * 512;
String[] q = SendFile.split("/");
int idx = q.length - 1;
try {
FileInputStream fileInputStream = new FileInputStream(file);
URL url = new URL(SendUrl);
connection = (HttpURLConnection) url.openConnection();
connection.setDoInput(true);
connection.setDoOutput(true);
connection.setUseCaches(false);
connection.setRequestMethod("POST");
connection.setRequestProperty("Connection", "Keep-Alive");
connection.setRequestProperty("User-Agent",
"Android Multipart HTTP Client 1.0");
connection.setRequestProperty("Content-Type",
"multipart/form-data; boundary=" + boundary);
outputStream = new DataOutputStream(
connection.getOutputStream());
outputStream.writeBytes(twoHyphens + boundary + lineEnd);
outputStream
.writeBytes("Content-Disposition: form-data; name=dosya; filename=\""+ q[idx] + "\"" + lineEnd);
outputStream.writeBytes("Content-Type: image/jpg" + lineEnd);
outputStream.writeBytes("Content-Transfer-Encoding: binary"+ lineEnd);
outputStream.writeBytes(lineEnd);
bytesAvailable = fileInputStream.available();
bufferSize = Math.min(bytesAvailable, maxBufferSize);
buffer = new byte[bufferSize];
bytesRead = fileInputStream.read(buffer, 0, bufferSize);
int boyut = 0;
while (bytesRead > 0) {
boyut += bytesRead;
outputStream.write(buffer, 0, bufferSize);
bytesAvailable = fileInputStream.available();
bufferSize = Math.min(bytesAvailable, maxBufferSize);
bytesRead = fileInputStream.read(buffer, 0, bufferSize);
dialog.setProgress(boyut);
}
outputStream.writeBytes(lineEnd);
String[] posts = Bilgiler.split("&");
int max = posts.length;
for (int i = 0; i < max; i++) {
outputStream.writeBytes(twoHyphens + boundary + lineEnd);
String[] kv = posts[i].split("=");
outputStream
.writeBytes("Content-Disposition: form-data; name=\""+ kv[0] + "\"" + lineEnd);
outputStream.writeBytes("Content-Type: text/plain"+ lineEnd);
outputStream.writeBytes(lineEnd);
outputStream.writeBytes(kv[1]);
outputStream.writeBytes(lineEnd);
}
outputStream.writeBytes(twoHyphens + boundary + twoHyphens
+ lineEnd);
inputStream = connection.getInputStream();
result = this.convertStreamToString(inputStream);
Log.v("TAG","result:"+result);
fileInputStream.close();
inputStream.close();
outputStream.flush();
outputStream.close();
} catch (Exception e) {
}
return null;
}
@Override
protected void onProgressUpdate(Integer... progress) {
dialog.setProgress(progress[0]);
}
@Override
protected void onPostExecute(Integer result1) {
dialog.dismiss();
};
private String convertStreamToString(InputStream is) {
BufferedReader reader = new BufferedReader(
new InputStreamReader(is));
StringBuilder sb = new StringBuilder();
String line = null;
try {
while ((line = reader.readLine()) != null) {
sb.append(line);
}
} catch (IOException e) {
e.printStackTrace();
} finally {
try {
is.close();
} catch (IOException e) {
e.printStackTrace();
}
}
return sb.toString();
}
и если вы отправляете в PHP, вы можете использовать это
<?php
$file_path = "test/";
$username= $_POST["username"];
$password= $_POST["password"];
$file_path = $file_path . basename( $_FILES['uploaded_file']['name']);
if(move_uploaded_file($_FILES['uploaded_file']['tmp_name'], $file_path)) {
echo "success";
} else{
echo "fail";
}
?>
Редактировать — 2:
Вы можете назвать это AsyncTask как:
String FormData = "username=" + Session.getUsername()
+ "&password=" + Session.getPassword() ;
SendFile SendIt= new SendFile(this, upLoadServerUri, filePath,FormData);
SendIt.execute();
