我有一个用 Java 实现的 Web 服务,当前由 WSE 3.0 客户端调用,我想从 WSE 迁移到 WCF。使用标准工具,我创建了一个可以调用 Web 服务的客户端,但它返回一个 SoapException 并显示“缺少必需的参数值”消息。Web 服务使用 HTTPS 并要求提供用户名和密码。在现有的 WSE 客户端代码中,子类化SecurityPolicyAssertion和SendSecurityFilter支持的凭据区域,如下所示:
public class UTClientAssertion : SecurityPolicyAssertion
{
public UTClientAssertion()
{
}
public override SoapFilter CreateClientOutputFilter(FilterCreationContext context)
{
return new ClientOutputFilter(this, context);
}
public override SoapFilter CreateClientInputFilter(FilterCreationContext context)
{
// we don't provide ClientInputFilter
return null;
}
public override SoapFilter CreateServiceInputFilter(FilterCreationContext context)
{
// we don't provide any processing for web service side
return null;
}
public override SoapFilter CreateServiceOutputFilter(FilterCreationContext context)
{
// we don't provide any processing for web service side
return null;
}
#region ClientOutputFilter
class ClientOutputFilter : SendSecurityFilter
{
public ClientOutputFilter(UTClientAssertion parentAssertion, FilterCreationContext context)
: base(parentAssertion.ServiceActor, false, parentAssertion.ClientActor)
{
}
public override void SecureMessage(SoapEnvelope envelope, Security security)
{
UsernameToken token = new UsernameToken("UserName", "Password", PasswordOption.SendPlainText);
security.Tokens.Add(token);
security.MustUnderstand = false;
}
}
#endregion
这些类应用于客户端中生成的代理类,如下所示:
// Create the web service client
ListService objListSvc = new ListService();
//code to set up the security policy and user assertion
UTClientAssertion objAssertion = new UTClientAssertion();
// create policy, add the assertion, and set it on the web service
Policy objPolicy = new Policy();
objPolicy.Assertions.Add(objAssertion);
objListSvc.SetPolicy(objPolicy);
我发现如果我编辑 WSE 客户端代码以删除行objListSvc.SetPolicy(objPolicy),我会收到相同的错误消息“缺少必需的参数值”。
与上面配置此 Web 服务的用户名和密码的 WSE 代码匹配的等效 WCF 配置/代码是什么?正在使用的 WCF 配置是生成的默认配置:
<basicHttpBinding>
<binding name="ListBinding" closeTimeout="00:01:00"
openTimeout="00:01:00" receiveTimeout="00:10:00" sendTimeout="00:01:00"
allowCookies="false" bypassProxyOnLocal="false" hostNameComparisonMode="StrongWildcard"
maxBufferSize="65536" maxBufferPoolSize="524288" maxReceivedMessageSize="65536"
messageEncoding="Text" textEncoding="utf-8" transferMode="Buffered"
useDefaultWebProxy="true">
<readerQuotas maxDepth="32" maxStringContentLength="8192" maxArrayLength="16384"
maxBytesPerRead="4096" maxNameTableCharCount="16384" />
<security mode="Transport">
<transport clientCredentialType="None" proxyCredentialType="None"

<message clientCredentialType="UserName" algorithmSuite="Default" />
</security>
</binding>
</basicHttpBinding>
