在PHP中理解SOAP时遇到困难

下面是我尝试使用的API：

以下是我尝试过的代码：

$client = new SoapClient('http://www.hotelscombined.com/api/LiveRates.asmx?WSDL');

echo '<pre>'; var_dump($client->__getFunctions()); echo '</pre><br /><br /><br />'; 
//since the above line returns the functions I am assuming everything is fine but until this point

try
{
    $client->__soapCall('HotelSearch',
        array(
            'ApiKey' => 'THE_API_KEY_GOES_HERE', // note that in the actual code I put the API key in...
            'UserID' => session_id(),
            'UserAgent' => $_SERVER['HTTP_USER_AGENT'],
            'UserIPAddress' => $_SERVER['REMOTE_ADDR'],
            'HotelID' => '50563',
            'Checkin' => '07/02/2009',
            'Checkout' => '07/03/2009',
            'Guests' => '2',
            'Rooms' => '1',
            'LanguageCode' => 'en',
            'DisplayCurrency' => 'usd',
            'TimeOutInSeconds' => '90'
        )
    );
}
catch (Exception $e)
{
    echo $e->getMessage();
}

注意：我以前从未使用过肥皂，所以我可能只是做了一些根本错误的事情，即使是一个小提示，让我朝着正确的方向走，我也会非常感激

Tom Haigh建议将这些值包装到另一个数组中，该数组似乎返回相同的错误消息：（我总是尝试将整数更改为整数形式，并且与日期相同）

我发现，当使用PHP的SOAP实现时，最终将所有内容封装在比您认为需要的更多的数组中

下面的示例似乎可行，但您还需要正确设置日期值的格式，然后才能正常工作。我不确定这样做的最佳方式——可能是您可以传递一个表示UNIX时间的整数，PHP将为您转换它

class HotelRequest {
   public $apiKey;
   public $userID;
   public $userAgent;
   public $userIPAddress;
   public $hotelID;
   public $checkin;
   public $checkout;
   public $guests;
   public $rooms;
   public $languageCode;
   public $displayCurrency;
   public $timeOutInSeconds;  
}

//set the values of the object...
$hotelRequestObject = new HotelRequest();
$hotelRequestObject->apiKey = "API_KEY";
//etc...

$client = new SoapClient('http://www.hotelscombined.com/api/LiveRates.asmx?WSDL',
    array("classmap" => array("HotelSearchRequest" => "HotelRequest")));

$result = $client->HotelSearch($hotelRequestObject);

var_dump($result);

有一件事让我疯狂了好几天——仔细检查数组元素的名称（ApiKey、UserId等）。确保案例也正确无误。我在一个大小写不正确的'm'上浪费了几个小时。

尝试创建一个PHP对象，然后在soap调用中引用该对象

对我来说不起作用，仍然得到同样的错误。我编辑了这个问题以显示我对您的评论的看法，我只使用了2个嵌套数组，而不是3个--遗漏了一个，因为您的示例中没有换行符。谢谢！我认为您更新的示例仍然缺少一个数组。

try
{
    $client->__soapCall('HotelSearch',
        array('request' =>
        array(
            'ApiKey' => 'THE_API_KEY_GOES_HERE', // note that in the actual code I put the API key in...
            'UserID' => session_id(),
            'UserAgent' => $_SERVER['HTTP_USER_AGENT'],
            'UserIPAddress' => $_SERVER['REMOTE_ADDR'],
            'HotelID' => '50563',
            'Checkin' => '2009-07-02',
            'Checkout' => '2009-07-03',
            'Guests' => 2,
            'Rooms' => 1,
            'LanguageCode' => 'en',
            'DisplayCurrency' => 'usd',
            'TimeOutInSeconds' => 90
        ) )
    );
}
catch (Exception $e)
{
    echo $e->getMessage();
}

$client->__soapCall('HotelSearch', 
    array(
        array('request' =>

                'DisplayCurrency' => 'usd',
                'TimeOutInSeconds' => '90'
            ) 
        ) 
    )
);

class HotelRequest {
   public $apiKey;
   public $userID;

   public $displayCurrency;
   public $timeOutInSeconds;  
}

//set the values of the object...
$hotelRequestObject = new HotelRequest();

$client = new SoapClient('http://www.hotelscombined.com/api/LiveRates.asmx?WSDL',
    array("classmap" => array("HotelSearchRequest" => "HotelRequest")));

$result = $client->HotelSearch($hotelRequestObject);

var_dump($result);
