如何使用SoapClient在PHP中使用"TransportWithMessageCredential"模式构建SOAP标头。我正在使用SoapClient，因为这似乎是最好的解决方案。以下内容来自给定的文档：
Web服务使用安全模式"TransportWithMessageCredential"。为了安全传输，正在使用SSL证书。此外，为了消息交换的安全性，需要用户名和密码的组合。用户名和密码在SOAP标头中传输。
示例：
<soapenv:Header>
<wsse:Security soapenv:mustUnderstand="1" xmlns:wsse="http://docs.oasisopen.
org/wss/2004/01/oasis-200401-wss-wssecurity-secext-1.0.xsd"
xmlns:wsu="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss wssecurityutility-1.0.xsd">
<wsse:UsernameToken wsu:Id="UsernameToken-37">
<wsse:Username>MyUsername</wsse:Username>
<wsse:Password Type="http://docs.oasisopen.org/wss/2004/01/oasis-200401-wss-username-token-profile-1.0#PasswordText">MyPassword!</wsse:Password>
<wsse:Nonce EncodingType="http://docs.oasisopen.org/wss/2004/01/oasis-200401-wss-soap-message-security-1.0#Base64Binary">vAvnhyzl+yP8Yb8ZVdKnMw==</wsse:Nonce>
<wsu:Created>2014-03-17T13:08:02.795Z</wsu:Created>
</wsse:UsernameToken>
</wsse:Security>
</soapenv:Header>
其中"MyUserName"answers"MyPassword！"为c。与实际登录信息交换。
wsdl可用于提供的每个功能。
此类返回具有以上定义格式的头：）
