在节点JS肥皂Web服务

我正在尝试使用npm模块soap在节点js中构buildsoap web服务。 我正在使用soap.listen函数在节点js中启动soap服务器。 我包括的wsdl文件如下所示：

<?xml version="1.0" encoding="UTF-8"?> <wsdl:definitions name="wscalc1" targetNamespace="http://localhost:8100/api/orderStatusWsdl" xmlns="http://localhost:8100/api/orderStatusWsdl" xmlns:http="http://schemas.xmlsoap.org/wsdl/http/" xmlns:soap="http://schemas.xmlsoap.org/wsdl/soap/" xmlns:wsdl="http://schemas.xmlsoap.org/wsdl/" xmlns:xs="http://www.w3.org/2001/XMLSchema"> <wsdl:message name="receiveOrderStatusRequest"> <wsdl:part name="a" type="xs:string"/> <wsdl:part name="b" type="xs:string"/> </wsdl:message> <wsdl:message name="receiveOrderStatusResponse"> <wsdl:part name="orderStatusResponse" type="xs:string"/> </wsdl:message> <wsdl:portType name="orderStatusPort"> <wsdl:operation name="receiveOrderStatus"> <wsdl:input message="receiveOrderStatusRequest"/> <wsdl:output message="receiveOrderStatusResponse"/> </wsdl:operation> </wsdl:portType> <wsdl:binding name="orderStatusBinding" type="orderStatusPort"> <soap:binding style="rpc" transport="http://schemas.xmlsoap.org/soap/http"/> <wsdl:operation name="receiveOrderStatus"> <soap:operation soapAction="receiveOrderStatus"/> <wsdl:input> <soap:body encodingStyle="http://schemas.xmlsoap.org/soap/encoding/" use="literal"/> </wsdl:input> <wsdl:output> <soap:body encodingStyle="http://schemas.xmlsoap.org/soap/encoding/" use="literal"/> </wsdl:output> </wsdl:operation> </wsdl:binding> <wsdl:service name="orderStatusService"> <wsdl:port binding="orderStatusBinding" name="orderStatus"> <soap:address location="http://localhost:8100/api/orderStatusWsdl"/> </wsdl:port> </wsdl:service> </wsdl:definitions> 

节点js代码：

 var orderStatusWsdlXml = fs.readFileSync(path.join(__dirname, 'soap/wsdl/myWsdl2.wsdl'), 'utf8') var soapServer = soap.listen(server, BASE_URL + '/orderStatusWsdl', orderStatusSoapService, orderStatusWsdlXml2) soapServer.log = function(type, data) { log.d('TYPE: ' + type) log.d('DATA: ' + JSON.stringify(data, null, 4)) } 

在运行节点项目之后，我尝试在SOAP UI客户端中加载WSDL，并出现以下错误：

 Error loading [http://localhost:8100/api/orderStatusWsdl]: org.apache.xmlbeans.XmlException: org.apache.xmlbeans.XmlException: error: Unexpected end of file after null 

我哪里错了？
