Wie man von Android-Daten zu Mysql

Question

schreibt

Ich habe eine Android-Anwendung, die Sie ein Video nach dem Einloggen hochladen können. Ich versuche, Benutzer zu verfolgen und eine MySQL-Abfrage einfügen, wenn sie ein Video hochladen. Also, im Grunde, wie poste ich den Benutzernamen in die PHP-Datei, wenn ein Benutzer ein Video hochlädt?

Meine upload.php Datei

if($_SERVER['REQUEST_METHOD']=='POST'){ 
     $file_name = $_FILES['myFile']['name']; 
     $file_size = $_FILES['myFile']['size']; 
     $file_type = $_FILES['myFile']['type']; 
     $temp_name = $_FILES['myFile']['tmp_name']; 

     $location = "uploads/"; 

     move_uploaded_file($temp_name, $location.$file_name); 
     echo "mylink.com/video/uploads/".$file_name; 
    }else{ 
     echo "Error"; 
    } 

Answer 1

hinzufügen Benutzernamen als Header-Informationen

conn.setRequestProperty("username", username); 

Jetzt können Sie den Header innerhalb upload.php

$android_username = $_SERVER['HTTP_username']; 

und schreiben Sie es auf Ihre MySQL-Datenbank erhalten:

$servername = "localhost"; 
$username = "username"; 
$password = "password"; 
$dbname = "myDB"; 

// Create connection 
$conn = new mysqli($servername, $username, $password, $dbname); 
// Check connection 
if ($conn->connect_error) { 
    die("Connection failed: " . $conn->connect_error); 
} 

$stmt = $conn->prepare("INSERT INTO uploads (username, filename) 
VALUES (?,?)"; 

$stmt->bind_param("ss", $android_username, $file_name); 

$stmt->execute(); 
$stmt->close(); 
$conn->close();
