我试图使用PHP连接到SOAP API，但不断收到以下错误：
Fatal error: SOAP-ERROR: Encoding: Violation of encoding rules
这是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">[email protected]</customer_email>
</customerpacket>
</loc:ws_customer_info>
</soapenv:Body>
</soapenv:Envelope>
这是我正在使用的代码导致错误：
<?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) '[email protected]',
'customerid' => (string) 0
];
$result = $accent->ws_customer_info($data);
我使用过__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">[email protected]</customer_email>
</customerpacket>
</ns1:ws_customer_info>
</SOAP-ENV:Body>
</SOAP-ENV:Envelope>
正如您通过比较两个请求所看到的那样，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。
UPDATE
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：
