PHP SoapClient:未知的WSDL扩展名

Question

我正在尝试实现在SAP PI系统上运行的Web服务.我得到的WSDL看起来像这样:

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

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

我的PHP文件看起来像这样(目前没有更多内容):

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

当我运行我的脚本时,我收到以下错误:

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

我试图在google和StackOverflow上搜索错误,并检查了php.net上的评论,但我似乎无法弄清楚为了让这个服务运行我必须改变什么.我也尝试打开W​​SDL扩展URL,它似乎存在.

有人可以在这扔我一块骨头吗？我尝试删除扩展程序网址,导致以下错误:

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

我现在能想到的唯一解决方案是更新您的UsingPolicy标记:

更改标签:

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

对此:

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

Answer 2

这在SAP环境中并不是正确的答案.在您的WSDL URL中,您将看到/ws_policy/- 将其更改为/standard/,您将能够使用PHP SoapClient类来使用Web服务,而无需维护WSDL的本地修改副本.您可以在此处的SAP博客上看到相同的内容(可能需要登录).

Answer 3

对于新版本，URL不再包含“ ws_policy”，而是包含0（标准）或1（策略）

例：

.... wsdl / flv_10002A1 1 1AD1 / bndg_url / ....（ws_policy）

.... wsdl / flv_10002A1 0 1AD1 / bndg_url / ....（标准）
