致命错误：SOAP-ERROR：编码：违反PHP中的编码规则

Question

我正在尝试使用PHP连接到SOAP API，但不断收到以下错误：

Fatal error: SOAP-ERROR: Encoding: Violation of encoding rules

以下是Web服务的WSDL：

我使用SOAP UI来测试服务，它在SOAP UI中运行良好。以下是SOAP UI发送的请求：

<soapenv:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:loc="http://localhost/">
   <soapenv:Header/>
   <soapenv:Body>
      <loc:ws_customer_info soapenv:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/">
         <customerpacket xsi:type="loc:LoyaltySchemecustomerpacket">
            <auth_id xsi:type="xsd:string">auth-code-here</auth_id>
            <customerid xsi:type="xsd:string">0</customerid>
            <customer_email xsi:type="xsd:string">someone@gmail.com</customer_email>
         </customerpacket>
      </loc:ws_customer_info>
   </soapenv:Body>
</soapenv:Envelope>

以下是我使用的导致错误的代码：

<?php
$context = stream_context_create([
    'http'=> [
        'user_agent' => 'PHPSoapClient'
    ]
]);

$accent = new \SoapClient( 'http://domain.com/loyaltyserver.php?wsdl', [
    'stream_context' => $context,
    'cache_wsdl' => WSDL_CACHE_NONE,
    'trace' => true
]);

$data = [
    'auth_id' => (string) 'my-auth-code',
    'customer_email' => (string) 'someone@gmail.com',
    'customerid' => (string) 0
];

$result = $accent->ws_customer_info($data);

我使用了__getLastRequest()，这是它发送的请求：

<?xml version="1.0" encoding="UTF-8"?>
<SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/" xmlns:ns1="http://localhost/" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:SOAP-ENC="http://schemas.xmlsoap.org/soap/encoding/" SOAP-ENV:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/">
<SOAP-ENV:Body>
    <ns1:ws_customer_info>
        <customerpacket xsi:type="ns1:LoyaltySchemecustomerpacket">
            <auth_id xsi:type="xsd:string">my-auth-code</auth_id>
            <customerid xsi:type="xsd:string">0</customerid>
            <customer_email xsi:type="xsd:string">someone@gmail.com</customer_email>
        </customerpacket>
    </ns1:ws_customer_info>
</SOAP-ENV:Body>
</SOAP-ENV:Envelope>

正如您所看到的那样，通过比较这两个请求它们是不同的但我不太了解SOAP以了解它们为何不同或导致错误的原因。

更新

如果我捕获异常并使用__getLastResponse()输出最后一个响应，我可以看到返回的似乎是有效响应。以下是回复：

Answer 1

问题出在服务器响应中。

XSD表示<statustext>标记类型为int，但是服务器返回字符串OK，从而中断了响应解析。
