在PHP中理解SOAP时遇到困难

soap php

Andrew G. Johnson · 技术社区 · 16 年前

下面是我尝试使用的API: http://www.hotelscombined.com/api/LiveRates.asmx?op=HotelSearch

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();
}

Server was unable to process request. ---> Object reference not set to an instance of an object.

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)

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();
}

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。

$client->__soapCall('HotelSearch', 
    array(
        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' => '07/02/2009',
                'Checkout' => '07/03/2009',
                'Guests' => '2',
                'Rooms' => '1',
                'LanguageCode' => 'en',
                'DisplayCurrency' => 'usd',
                'TimeOutInSeconds' => '90'
            ) 
        ) 
    )
);

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。我在一个错误的“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。

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);
