在PHP中无法理解SOAP
Having trouble getting my head around SOAP in PHP
问：
好吧，这是我尝试使用的 API：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();
}
Anywho 这会引发异常并回显以下内容：
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，所以有可能我只是做了一些根本性错误的事情，即使是让我朝着正确方向前进的小技巧也会不胜感激
Tom Haigh 建议将值包装在另一个数组中，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();
}

我发现，当使用PHP的SOAP实现时，你最终会把所有东西都包装在比你想象的更多的数组中。
下面的示例似乎有效，但您还需要正确设置日期值的格式，然后才能正常工作。我不确定最好的方法 - 可能是您可以传递一个表示 UNIX 时间的 Integer，PHP 会为您转换它。
$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'
)
)
)
);

对我不起作用，仍然遇到同样的错误。我编辑了问题以显示我尝试过的内容

啊，很好的电话，你的评论，我只有 2 个嵌套数组，而不是 3 个——错过了一个，因为你的例子中没有换行符。多谢！

有一件事让我发疯了好几天 - 仔细检查数组元素的名称（ApiKey、UserId 等）。也要确保大小写正确。我浪费了几个小时在一个错误大小写的“m”上。

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);
