PHPPUT方法Slim框架

請問為什么 put 只包含一個空欄位？當帖子正常作業時？

$app->post('/books', function (Request $request, Response $response, $args){
    $book = Books::fromResultSet($request->getParsedBody());
    if($book->valid())
        return $response->withStatus(400);

    $book->insert();
    return $response->withStatus(201);
})->add($securityMiddleware);

$app->put('/books/{id}', function (Request $request, Response $response, $args){
    $book = Books::fromResultSet($request->getParsedBody());
    print_r($book);

    /*if($book->valid())
        return $response->withStatus(400);

    $book->update();
    return $response->withStatus(201);*/
})->add($securityMiddleware);

列出print_r后的錯誤($request->getParsedBody())
