上传策略的callbackBody字段设置fsize这个魔法变量即可：

php的话就是生成token的地方

 $bucket = Config::BUCKET_NAME;
    $accessKey = Config::ACCESS_KEY;
    $secretKey = Config::SECRET_KEY;
    $auth = new Auth($accessKey, $secretKey);

    $policy = array(
      'callbackUrl' => 'http://172.30.251.210/callback.php',
      'callbackBody' => '{"fname":"$(fname)", "fsize":"$(fsize)", "fkey":"$(key)", "desc":"$(x:desc)", "uid":' . $uid . '}'
      );

    $upToken = $auth->uploadToken($bucket, null, 3600, $policy);

    header('Access-Control-Allow-Origin:*');
    echo $upToken;
