难以理解PHP中的SOAP [英] Having trouble getting my head around SOAP in PHP

问题描述

以下是我要使用的API: http://www.hotelscombined.com/api/LiveRates.asmx?op=HotelSearch

Well here is the API I'm trying to use: http://www.hotelscombined.com/api/LiveRates.asmx?op=HotelSearch

这是我尝试过的代码:

$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();
}

这会引发异常并回显以下内容:

Anywho this throws an exception and echos the following:

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SOAP，所以很可能我只是在做一些根本上错误的事情，即使是向我介绍正确方向的小技巧也将受到高度赞赏

NOTE: I've never used SOAP before so it's possible I'm just doing something fundamentally wrong, even a small tip to get me in the right direction would be hugely appreciated

Tom Haigh建议将值包装在另一个似乎返回相同错误消息的数组中:(我一直尝试将整数更改为整数形式，并与日期相同)

Tom Haigh suggested wrapping the values in another array which seems to be returning the same error message: (I always tried changing integers to be in integer form and the same with dates)

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();
}

推荐答案

我发现，使用PHP的SOAP实现时，您最终将所有内容包装在比您认为需要的更多数组中.

I find when using PHP's SOAP implementation you end up wrapping everything up in more arrays than you think you need.

以下示例似乎有效，但是您还需要正确设置日期值的格式才能生效.我不确定执行此操作的最佳方法-可能是您可以传递代表UNIX时间的Integer，而PHP会为您转换它.

The below example seems to work, but also you need to format your date values correctly before it will work. I'm not sure of the best way of doing this - it might be that you can pass an Integer representing UNIX time and PHP will convert it for you.

$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'
            ) 
        ) 
    )
);
