Question

我目前正在使用Silex 1.3内部的Doctrine DBAL 2.5版来对MySQL DB进行REST调用。我设法让我的GET / GET / {id}和DELETE / {id}相当容易，但我似乎无法让我的POST / PUT工作。

以下是暂停代码

$app->post('/student', function($firstName, $lastName) use($app) {
    $sql = "INSERT INTO tbl_students (firstName, lastName)
            VALUES (:firstName, :lastName)";
    $student = $app['db']->prepare($sql);
    $student->bindValue(':firstName', $firstName, PDO::PARAM_STR);
    $student->bindValue(':lastName', $lastName, PDO::PARAM_STR);

    $student->execute();

    return "insert successful";
});

$app->put('/student/{id}', function($id, $firstName, $lastName) use($app){
    $sql = "UPDATE tbl_students 
            SET firstName = :firstName, lastName = :lastName 
            WHERE id = :id";
    $student = $app['db']->prepare($sql);
    $student->bindValue(':id', $id, PDO::PARAM_INT);
    $student->bindValue(':firstName', $firstName, PDO::PARAM_STR);
    $student->bindValue(':lastName', $lastName, PDO::PARAM_STR);
    $student->execute();

    return "student succesfully updated";
});

如果我硬编码默认值，它可以很好地使用bindParam（）并使用我自己的值。

我的curl将所有内容反馈给我后，我一直收到此错误消息

<span class="exception_message">Controller &quot;Closure&quot; requires that you provide a value for the &quot;$firstName&quot; argument (because there is no default value or because there is a non optional argument after this one).</span>

以下是我使用的暂停卷曲命令

curl -X POST -d "firstName=First123&lastName=Last456" URL/student
curl -X POST -d '{"firstName":"First123","lastName":"Last456"}' URL/student --header "Content-Type:application/json"
curl -X POST -d "firstName=First123&lastName=Last456" URL/student --header "Content-Type:text/html"

Silex不会自动为与您的帖子变量对应的方法创建参数。你必须像@Artamiel建议的那样从请求对象中获取它们。

请参阅http://silex.sensiolabs.org/doc/usage.html#example-post-route。

您的后期操作的更新代码应如下所示：

$app->post('/student', function(Request $request) use($app) {
    $firstName = $request->get('firstName');
    $lastName = $request->get('lastName');
    $sql = "INSERT INTO tbl_students (firstName, lastName)
            VALUES (:firstName, :lastName)";
    $student = $app['db']->prepare($sql);
    $student->bindValue(':firstName', $firstName, PDO::PARAM_STR);
    $student->bindValue(':lastName', $lastName, PDO::PARAM_STR);

    $student->execute();

    return "insert successful";
});

Silex - 我的REST POST / PUT调用没有接收参数
