php - 使用 Slim 测试 PUT 参数值的问题

Question

我不完全理解它与 PUT 变量和 Slim 的关系。

请考虑以下路线:

$app->put('/users/me',function() use ($app){
    $app->response->headers->set('Content-Type', 'application/json');
    $userData = $app->request()->put();
    var_dump($userData);
});

这个路由基本上接受一个 PUT 请求并返回它附带的任何变量。当我用 curl 测试它时，它似乎按预期工作:

oris@oris:~/slim-api$ curl -i -H "Accept: application/json" -X PUT -d "hello=there" http://slim-api.com/users/me
HTTP/1.1 200 OK
Server: nginx/1.2.1
Date: Thu, 06 Feb 2014 09:53:11 GMT
Content-Type: application/json
Transfer-Encoding: chunked
Connection: keep-alive
X-Powered-By: PHP/5.4.6-1ubuntu1.5
Set-Cookie: PHPSESSID=2r6ta2fg6vdk7; path=/
Expires: Thu, 19 Nov 1981 08:52:00 GMT
Cache-Control: no-store, no-cache, must-revalidate, post-check=0, pre-check=0
Pragma: no-cache

array(1) {
    ["hello"]=>
    string(5) "there"
}

我用 bootstrap.php file 为这条路线写了一点 PHPUnit 测试:

 public function testPutUsersMe()
{
    $this->put('/users/me',array("myKey=myValue"));
    $userResponse = $this->response->body();
    var_dump($userResponse);
}

我还向这个引导文件添加了一个小的附加项，以根据每个请求更新超全局变量:

//sets php super globals so other packages would have access to them on tests context
public function setRequestGlobals($method,$path,$options = array())
{
    $_SERVER['REQUEST_METHOD'] = $method;
    if (!empty($options)){
        if ($method === "GET"){
            foreach($options as $key => $value){
                $_GET[$key] = $value;
            }
        }
        if ($method === "POST"){
            foreach($options as $key => $value){
                $_POST[$key] = $value;
            }
        }
        if ($method === "PUT"){
            foreach($options as $key => $value){
                $_POST[$key] = $value;
            }
        }
    }

}

我在 request 方法中调用了 $this->setRequestGlobals($method,$path,$options);。但这会导致以下不太正确的响应:

oris@oris:~/slim-api$ phpunit
PHPUnit 3.7.29 by Sebastian Bergmann.

Configuration read from /home/oris/slim-api/phpunit.xml

...........string(44) "Array
(
    [slim.input] => myKey=myValue
)
"


Time: 119 ms, Memory: 7.75Mb

OK (11 tests, 85 assertions)
oris@oris:~/slim-api$ 

我所说的“不太正确”的意思是 [slim.input] 现在是参数值，键和值是值。如果我将路由(和测试)方法更改为 POST，我将获得预期的输出:

oris@oris:~/slim-api$ phpunit
PHPUnit 3.7.29 by Sebastian Bergmann.

Configuration read from /home/oris/slim-api/phpunit.xml

...........string(33) "Array
(
    [myKey] => myValue
)
"


Time: 128 ms, Memory: 7.75Mb

OK (11 tests, 85 assertions)
oris@oris:~/slim-api$ 

问题:

• 通常，我如何将带有 curl 的数组传递给此路由，而不是 flat key1=value1, key2=value2 ？

• 当唯一改变的是请求方法时，为什么测试输出中会发生这种变化？

奇怪的是，当我深入研究 Slim 代码时，在 /vendor/slim/slim/Slim/Http/Request.php 上，我看到 put 函数只是 post 的别名:

    /**
 * Fetch PUT data (alias for \Slim\Http\Request::post)
 * @param  string           $key
 * @param  mixed            $default Default return value when key does not exist
 * @return array|mixed|null
 */
public function put($key = null, $default = null)
{
    return $this->post($key, $default);
}

Answer 1

据我所知，slim 需要先配置 header 以接受 'PUT' 方法或者您需要将 '_METHOD=PUT' 的参数与数据数组一起添加，并将请求作为 'POST' 发送。传递的参数可能如下所示:array("_METHOD"=>"PUT","data"=>array("myKey"=>"myValue"))
