iOS调用web service

[sinat_23117551]

用iOS soap消息调用的web service,无参的返回正常，带参的返回错误，错误信息是 <soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/"><soap:Body><soap:Fault><faultcode>soap:Client</faultcode><faultstring>Unmarshalling Error: unexpected element (uri:"http://service.zhfs.lab516/", local:"name"). Expected elements are <{}password>,<{}name> </faultstring></soap:Fault></soap:Body></soap:Envelope>，这是哪里的问题，求教
