我检查过类似的问题，但没有一个能解决我面临的问题。

我正在构建 Web 服务，我想从 HTTP POST 请求中检索 XML 数据，处理数据并返回响应。编写脚本时应考虑以下信息:

 The communication mode is HTTP POST (not SOAP) 
 The content type is text/xml. 
 The POST request will contain only XML
 The request will be a RAW POST directly to stream and NOT in a parameter.

我已经尝试过，但我的脚本没有从 HTTP POST 请求中捕获数据。

我的脚本:

  $postData = file_get_contents('php://input');

  if(!empty($xml->MerchantReference)){
     $merchRef = (string)$xml->MerchantReference;
     $custRef = (int)$xml->CustReference;
     $username = (string)$xml->ServiceUsername;
     $password = (string)$xml->ServicePassword;
     $db->setQuery(Check if customer exists in database);
     if($db->countResultset() == 0)
     {
        header("Content-type: text/xml");
        echo "<?xml version='1.0' encoding='UTF-8'?>";
        echo "<CustomerInformationResponse>";
            echo "<MerchantReference>".$merchRef."</MerchantReference>";
            echo "<Customers>";
                echo "<Customer>";
                    echo "<Status>0</Status>";
                    echo "<CustReference>".$custRef."</CustReference>";
                    echo "<FirstName/>";
                    echo "<LastName/>";
                    echo "<OtherName/>";
                    echo "<Email/>";
                    echo "<Phone/>";
                    echo "<ThirdPartyCode/>";
                    echo "<StatusMessage>Customer is valid</StatusMessage>";
                echo "</Customer>";
            echo "</Customers>";
        echo "</CustomerInformationResponse>";
        exit;
     }

这是 HTTP POST 请求:

  <CustomerInformationRequest xmlns:ns2="http://test.url.com/" xmlns:ns3="http://www.w3.org/2003/05/soap-envelope">
     <ServiceUrl>MY URL</ServiceUrl>
     <ServiceUsername>12345</ServiceUsername>
     <ServicePassword>abcdef</ServicePassword>
     <RouteId>HTTPGENERICv31</RouteId>
     <Service>bill</Service>
     <MerchantReference>123456</MerchantReference>
     <CustReference>abcdef</CustReference>
     <PaymentItemCategoryCode/>
     <RequestReference/>
     <TerminalId/>
     <Amount>0</Amount>
     <FtpUsername/>
     <FtpPassword/>
 </CustomerInformationRequest>

检索和处理数据后，我的脚本返回响应。 响应应该是这样的:

     <CustomerInformationResponse>
        <MerchantReference>3527</MerchantReference >
           <Customers>
              <Customer>
                 <Status>0</Status>                    
                 <CustReference>4565</CustReference>
                 <FirstName></FirstName>                                           
                 <LastName></LastName>
                 <OtherName></OtherName>
                 <Email></Email>
                 <Phone></Phone>
                 <ThirdPartyCode/>                                                    
                 <StatusMessage>Customer is Valid</StatusMessage>
               </Customer>
             </Customers>
           </CustomerInformationResponse>

最佳答案

经过大量研究，我找到了问题的答案。我发现从 HTTP Post 请求中获取数据后，我没有将其存储为 xml 数据。

所以加入这行代码

 $xml = simplexml_load_string($postData);

在此之后

 $postData = file_get_contents('php://input');

解决了。我想我应该分享它，因为它可能对某人有用。

关于xml - 使用 php 从 HTTP POST 请求中检索 XML，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/26742078/
