我在另一台服务器上有一个 .NET ASMX Web 服务，并且我在另一台服务器上安装了 mule 独立 CE 3.4。我有一个非常简单的流程，需要调用这个 .NET Web 服务并传递两个字符串参数。

<?xml version="1.0" encoding="UTF-8"?>

<mule xmlns:http="http://www.mulesoft.org/schema/mule/http" xmlns:cxf="http://www.mulesoft.org/schema/mule/cxf" xmlns="http://www.mulesoft.org/schema/mule/core" xmlns:doc="http://www.mulesoft.org/schema/mule/documentation" xmlns:spring="http://www.springframework.org/schema/beans" version="CE-3.4.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-current.xsd

http://www.mulesoft.org/schema/mule/cxf http://www.mulesoft.org/schema/mule/cxf/current/mule-cxf.xsd">
    <custom-transformer returnClass="java.lang.String[]" mimeType="text/plain" class="com.rms.corpapps.utils.WebServiceParamsTransformer" name="Java" doc:name="Java"/>
<http:connector name="httpConnector" enableCookies="true" proxyHostname="myserver" proxyUsername="domain\myusername" proxyPassword="mypassword" proxyPort="80" >
    <spring:property name="proxyNtlmAuthentication" value="true"/>
</http:connector>
<flow name="sftestFlow1" doc:name="sftestFlow1">
    <http:inbound-endpoint exchange-pattern="request-response" host="localhost" port="8081" doc:name="HTTP" path="flows/sftest"/>
    <custom-transformer class="com.mycompany.utils.WebServiceParamsTransformer" doc:name="Transform Data for web service" doc:description="This java component prepares the input for web service"/>
    <cxf:jaxws-client doc:name="SOAP"
        clientClass="com.mycompany.WebServiceListener" port="WebServiceListenerSoap"  operation="ProcessExternalMessage"
    />
    <outbound-endpoint address="http://myserver/sm/webservicelistener.asmx?wsdl" doc:name="Generic" exchange-pattern="request-response" connector-ref="httpConnector"/>
</flow>

基本上，我公开了一个 http 入站端点（用于测试目的）来调用流程并使用一个 java 转换器类，该类返回需要传递给 Web 服务的字符串。这是 WebServiceParamsTransformer 类的代码。

public class WebServiceParamsTransformer extends AbstractTransformer {
    @Override
    public Object doTransform(Object src, String encoding) throws TransformerException {
        Object[] out = new Object[2];
    out[0] = "Update Ticket Service";
    out[1] = Base64.encode("<?xml version=\"1.0\" encoding=\"UTF-8\" standalone=\"yes\"?><event source=\"SHUB\" target=\"TP\" type=\"SUB8\" version=\"1.0\" timestamp=\"2013-09-16T15:52:14.0000+00.00\"><new-eta-event><incident-number>123456</incident-number><user-name>hari</user-name><eta-timestamp>2013-09-16T15:52:14.0000+00.00</eta-timestamp></new-eta-event></event>");

    return out;
    }
}

不幸的是，这不起作用 - 我收到以下错误“响应代码：401。未经授权”。以下是错误日志的摘录：

.NET Web 服务受 Windows 集成身份验证保护，并在 .NET Framework 2.0 中的 Windows Server 2008 下的 IIS 7 中运行。这是显示身份验证设置的屏幕截图。

在此处输入图像描述

我在哪里做错了？我的要求是简单地调用一个由 mule esb 集成身份验证保护的 Web 服务。任何帮助深表感谢。

这是由于身份验证异常而发生的。

<cxf:jaxws-client operation="Get_Workers"
            clientClass="com.saba.workday.ws.human_resources.HumanResourcesService"
            port="Human_Resources" wsdlLocation="classpath:Human_Resources.wsdl"
            doc:name="Get_Workers">
            <cxf:outInterceptors>
                <spring:ref bean="CredentialsSupplierBean" />
            </cxf:outInterceptors>
        </cxf:jaxws-client>

这里的 Credential Supplier 是一个扩展 WSS4JOutInterceptor 的 bean。并进行身份验证。

凭证供应商：

public class CredentialsSupplier extends WSS4JOutInterceptor {

 public CredentialsSupplier() {
    setProperty("action", "UsernameToken");
    setProperty("passwordType", "PasswordText");
 }

    @Override
    public void handleMessage(SoapMessage message) {
        super.handleMessage(prepareHandleMessage(message));
    }

    protected SoapMessage prepareHandleMessage(SoapMessage message) {
            message.setContextualProperty("user", "username");
            message.setContextualProperty("password", "pswd");
        return message;
    }
}
