Je voudrais télécharger l'image à la base de données mysql de l'application Android en utilisant le service RESTful. est leur tout côté service et côté android tutorial.Please aider gentiment à fournir des échantillons RESTful et androidcomment télécharger le fichier image à mysql à partir d'android en utilisant Restful webservice
Merci à l'avance
Ce Tutorial aidera les fichiers d'image de téléchargement et
Ce tutorial vous aidera à écrire des images à la base de données.
Ajout des parties de code:
Webservice pour le téléchargement de fichiers:
@Path("/file")
public class UploadFileService {
@POST
@Path("/upload")
@Consumes(MediaType.MULTIPART_FORM_DATA)
public Response uploadFile(
@FormDataParam("file") InputStream uploadedInputStream,
@FormDataParam("file") FormDataContentDisposition fileDetail) {
String uploadedFileLocation = "d://uploaded/" + fileDetail.getFileName();
// save it
writeToFile(uploadedInputStream, uploadedFileLocation);
String output = "File uploaded to : " + uploadedFileLocation;
/************************************************/
// CALL THE IMAGE UPLOAD TO DB CODE HERE.
// InsertImageTest.insertImage();
/*************************************************/
return Response.status(200).entity(output).build();
}
// save uploaded file to new location
private void writeToFile(InputStream uploadedInputStream,
String uploadedFileLocation) {
try {
OutputStream out = new FileOutputStream(new File(
uploadedFileLocation));
int read = 0;
byte[] bytes = new byte[1024];
out = new FileOutputStream(new File(uploadedFileLocation));
while ((read = uploadedInputStream.read(bytes)) != -1) {
out.write(bytes, 0, read);
}
out.flush();
out.close();
} catch (IOException e) {
e.printStackTrace();
}
}
}
JAVA CODE POUR SAUVEGARDER D'IMAGE DB
public class InsertImageTest {

La meilleure et facile télécharger n'importe quel fichier d'android à Mysql ser Ver est via l'utilisation de la bibliothèque client FTP. Link
Trouver le fichier ftp4j-1.6.jar et importer dans votre projet
vous pouvez télécharger l'image sur votre serveur via le code ci-dessous.
public void upload(){
FTPClient con = null;
con = new FTPClient();
con.connect("192.168.2.57"); // Your Server IP and Port you can use FTP domain credentials here also
if (con.login("XXXXXXXXX", "XXXXX")) // FTP username and Pass
{
con.enterLocalPassiveMode(); // important!
con.setFileType(FTP.BINARY_FILE_TYPE);
String data = "/sdcard/vivekm4a.m4a"; // Your File Path
FileInputStream in = new FileInputStream(new File(data));
boolean result = con.storeFile("/vivekm4a.m4a", in);
in.close();
if (result) Log.v("upload result", "succeeded");
con.logout();
con.disconnect();
}
}
}
Hope this helps
Si vous souhaitez télécharger l'image par le service Web s'il vous plaît vérifier ci-dessous le code
public function changeprfoilePicture()
{
// $username='maik';
$userid = $_POST['userid'];
$currentdate = date('Y-m-d H:i:s');
$where=array('id'=>$userid);
$alias='id';
$tabel='user';
$userData = $this->commonmodel->getData($alias,$tabel,$where);
if(empty($userData))
{
echo "User not found";
die;
}
$cur_timestamp = time();
// profile thumb image
if(isset($_POST['v_thumb_image']) && trim($_POST['v_thumb_image']) !='')
{
if($userData != array())
{
$thumb_img = $_POST['v_thumb_image'];
$thumb_img = str_replace('data:image/jpeg;base64,', '', $thumb_img);
$thumb_img = str_replace(' ', '+', $thumb_img);
$data = base64_decode($thumb_img);
$file_name = $userid."_".$cur_timestamp.'.jpg';
$file = profile_thumb . $file_name;
$success = file_put_contents($file, $data);
}
else
{
echo $this->common->customFailMessage("User not found");
die;
}
}
// Uplaod main image
if(isset($_POST['userfile']) && trim($_POST['userfile']) !='')
{
$mian_img = $_POST['userfile'];
$mian_img = str_replace('data:image/jpeg;base64,', '', $mian_img);

$data = base64_decode($mian_img);
$file_name = $userid."_".$cur_timestamp.'.jpg';

$success = file_put_contents($file, $data);
}
if($success)
{
$valuesArray=array('update_time'=>"$currentdate",'profilepicture'=>"$file_name");
$where= array('id'=>$userid);
$this->commonmodel->updateData('user',$valuesArray,$where);
$status='Success';
$xml = new SimpleXMLElement('<Response/>');
$xml->addChild('status', 'Success');
$xml->addChild('profilepicture', $file_name);
print ($xml->asXML());
}
else
