Question

我将xml数据发送到远程服务器（网站）。得到它的回应。现在我想将这些接收到的值保存在变量中以供进一步使用。但我无法这样做。

以下是完整的代码：

<?php
$xml = '<?xml version="1.0" encoding="UTF-8" ?> <Request> <Source> <RequestorID Client="1921" EMailAddress="XML.ALTECH@TRAVELDEN.COM" Password="PASS" /> 
<RequestorPreferences Language="en" Currency="GBP" Country="GB">

<RequestDetails> <SearchHotelPriceRequest> <ItemDestination DestinationType="city" DestinationCode="LON" /> 
<ImmediateConfirmationOnly /> <PeriodOfStay> <CheckInDate>2015-12-08</CheckInDate> <Duration>2</Duration>

' ;
$url = 'https://interface.demo.gta-travel.com/wbsapi/RequestListenerServlet';
   //setting the curl parameters.
 $headers = array(
    "Content-type: text/xml;charset=\"utf-8\"",
    "Accept: text/xml",
    "Cache-Control: no-cache",
    "Pragma: no-cache",
    "SOAPAction: \"run\""
 );
        try{

            $ch = curl_init();
            curl_setopt($ch, CURLOPT_URL, $url);
            curl_setopt($ch, CURLOPT_POST, 1);
            // send xml request to a server
            curl_setopt ($ch, CURLOPT_SSL_VERIFYHOST, 0);
            curl_setopt ($ch, CURLOPT_SSL_VERIFYPEER, 0);
            curl_setopt($ch, CURLOPT_POSTFIELDS,  $xml);
            curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
            curl_setopt($ch, CURLOPT_VERBOSE, 0);
            curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
            echo $ch;
            $data = curl_exec($ch);

            echo $data;


            if($data === false){
                $error = curl_error($ch);
                echo $error; 
                die('error occured');
            }else{
                $newxml=$data;
                echo $data;
                echo '<pre>';
                echo htmlspecialchars(print_r($newxml, true));
                echo '<pre>';   
            $dataPOST = trim(file_get_contents($data));
            $xmlData = simplexml_load_string($dataPOST);                
            echo $xmlData->Response->ResponseDetails->SearchHotelPriceResponse->HotelDetails->Hotel['HasMap'];
            }
            curl_close($ch);
        }catch(Exception  $e){
            echo 'Message: ' .$e->getMessage();die("Error");
    }
?>

我收到的错误是“尝试获取非对象的属性”，并且还警告警告：file_get_contents（

$dataPOST = trim(file_get_contents($data));
            $xmlData = simplexml_load_string($dataPOST);                
            echo $xmlData->Response->ResponseDetails->SearchHotelPriceResponse->HotelDetails->Hotel['HasMap'];

这是我在xml

中从服务器中调用的输出代码

var_dump($xmlData)将是＆＃34; false＆＃34;用你的代码......

使用file_get_contents()无效，您正试图从磁盘加载＆＃34;当$data是一个字符串时。

您还试图错误地获取属性。

找到此代码：

$dataPOST = trim(file_get_contents($data));
$xmlData = simplexml_load_string($dataPOST);                
echo $xmlData->Response->ResponseDetails->SearchHotelPriceResponse->HotelDetails->Hotel['HasMap'];

将其更改为此代码：

$xmlData = simplexml_load_string($data);                
echo $xmlData->ResponseDetails->SearchHotelPriceResponse->HotelDetails->Hotel->attributes()->HasMap;

将xml数据发送到服务器，接收它并保存到php中的变量中
