PHP SoapClient：未知所需WSDL擴展

Question

我試圖實現在SAP PI系統上運行的Web服務。我得到的WSDL看起來是這樣的：

<?xml version="1.0" encoding="UTF-8"?>

     </wsdl:port> 
    </wsdl:service> 
</wsdl:definitions> 

我的PHP文件看起來像這樣（沒有更多的它目前）：

<?php 
$client = new SoapClient('test.wsdl'); 
?> 

當我跑步時我的劇本，我拋出了以下錯誤：

Fatal error: Uncaught SoapFault exception: [WSDL] SOAP-ERROR: Parsing WSDL: Unknown required WSDL extension 'http://schemas.xmlsoap.org/ws/2004/09/policy' in /srv/www/htdocs/wsdl.php:2 Stack trace: #0 /srv/www/htdocs/wsdl.php(2): SoapClient->SoapClient('test.wsdl') #1 {main} thrown in /srv/www/htdocs/wsdl.php on line 2 

我試圖尋找谷歌和StackOverflow上的錯誤，並且還檢查php.net的意見，但我似乎無法找出我不得不爲了得到這種改變服務運行。我也嘗試打開W​​SDL擴展URL，它似乎存在。

有人可以在這裏扔骨頭嗎？我試圖消除擴展URL，這會導致以下錯誤：

Fatal error: Uncaught SoapFault exception: [WSDL] SOAP-ERROR: Parsing WSDL: Unexpected WSDL element <UsingPolicy> in /srv/www/htdocs/wsdl.php:2 Stack trace: #0 /srv/www/htdocs/wsdl.php(2): SoapClient->SoapClient('test.wsdl') #1 {main} thrown in /srv/www/htdocs/wsdl.php on line 2 

Answer 1

我能想到的，在這一點上是更新您的UsingPolicy標籤的唯一解決辦法：

更改標籤：

<wsp:UsingPolicy wsdl:required="true"/> 

這樣：

<wsp:UsingPolicy wsdl:required="false"/> 

Answer 2

這是不是真的在SAP環境中的正確答案。在WSDL的URL中，您將看到/ws_policy/ - 將其更改爲/standard/，您將能夠使用PHP SoapClient類來使用Web服務，而無需維護本地修改的WSDL副本。您可以在SAP博客here上看到相同的內容（可能需要登錄）。

Answer 3

For new versions the URL is not containing anymore the "ws_policy" instead there is a 0 (standard)or 1 (policy)

Example:

....wsdl/flv_10002A111AD1/bndg_url/.... (ws_policy)

....wsdl/flv_10002A101AD1/bndg_url/.... (standard)

Answer 4

似乎是在PHP SoapServer時的錯誤，或缺少擴展兼容性，還尚未得到解決，至少在PHP 31年6月5日。

我能找到的唯一解決辦法是設定要求UsingPolicy到false，如建議在接受響應：

<wsp:UsingPolicy wsdl:required="false" /> 

但是客戶端可以訪問，而無需身份驗證的SOAP服務，這是一個嚴重的安全問題。所以，我試圖手動檢查安全數據是由客戶端發送的。

$soapEnvelope = new DOMDocument(); 
$soapEnvelope->loadXML(file_get_contents("php://input"), LIBXML_DTDATTR); 
$wsseNamespace = "http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-secext-1.0.xsd"; 

if ($soapEnvelope->getElementsByTagNameNS($wsseNamespace, 'Security')->length == 0) { 
    throw new SoapFault("auth", 'Authentication error - Missing wsse:Security node'); 
} 

if ($soapEnvelope->getElementsByTagNameNS($wsseNamespace, 'UsernameToken')->length == 0) { 
    throw new SoapFault("auth", 'Authentication error - Missing UsernameToken node'); 
} 

if ($soapEnvelope->getElementsByTagNameNS($wsseNamespace, 'Username')->length == 0) { 
    throw new SoapFault("auth", 'Authentication error - Missing Username node'); 
} 

if ($soapEnvelope->getElementsByTagNameNS($wsseNamespace, 'Password')->length == 0) { 
    throw new SoapFault("auth", 'Authentication error - Missing Password node'); 
} 

// SOAPServer handle requests method 
$server->handle(); 

這是一個骯髒的把戲，但它的作品。
