PHP没有得到VolleyMultipartRequest发布的预期POST [Android]

标签: php android mysql request android-volley

当我发送请求时,PHP文件返回“请求的字段丢失”。

这是因为没有按预期收到POST变量。

VolleyMultipartRequest是否发送了正确的byte []数据?

MainActivity

用于插入的PHP文件

    // include db connect class (php-Datei für Verdbindung einbinden)
    require_once __DIR__ . '/db_connect.php';

    // connecting to db
    $con = new DB_CONNECT();

    // mysql inserting a new row
    $query  = "INSERT INTO test(byteArray) VALUES('$byteArray')";
    $result = mysqli_query($con->connect(), $query);

    // check if row inserted or not
    if ($result) {
        // successfully inserted into database
        $response["success"] = 1;
        $response["message"] = "byteArray erfolgreich hinzugefügt!";

        // echoing JSON response (JSON File generieren mit ergebnisArray ($response)
