如果这篇文章感觉太长,我提前道歉。但是 1)这是我的第一篇文章,2)我真的已经过了河,穿过树林试图弄清楚这一点。
Visual Studio 2012 中的添加服务引用功能会生成一个代理,该代理(显然)会生成无效的 SOAP 消息。我怀疑它与序列化或代理类型的装饰方式有关,但我似乎无法弄清楚。非常感谢您的帮助。
详细信息 1. 我的环境是 Visual Studio 2012,我创建了一个 .NET 4.5 类库,其中包含对https://sandbox-api.bancbox.com/v1/BBXPort?wsdl的服务引用。我正在尝试调用 getClient() 函数;这是在这里定义的。( http://www.bancbox.com/api/view/45 )
代码如下所示:
public void GetClient()
{
// create an instance of the service reference proxy class
var bbx=newBBXClient();
bbx.ChannelFactory.Endpoint.Behaviors.Remove<System.ServiceModel.Description.ClientCredentials>();
bbx.ChannelFactory.Endpoint.Behaviors.Add(new CustomCredentials());
bbx.ClientCredentials.UserName.UserName="MY_USERNAME";
bbx.ClientCredentials.UserName.Password="MY_PASSWORD";
var customerId=newid {
subscriberReferenceId="44XX33YY"
};
var request=newgetClientRequest {
subscriberId=MY_SUBSCRIBER_ID,
clientId=customerId
};
var response=bbx.getClient(request);
}
细节 2. 我通过 SoapUI 成功调用了 Web 服务。成功的 SoapUI 生成的 SOAP 消息如下所示
<soapenv:Envelope xmlns:sch="schema.bancbox.com" xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/">
<soapenv:Header>
<wsse:Security soapenv:mustUnderstand="1" xmlns:wsse="http://docs.oasis-open.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-wssecurity-utility-1.0.xsd">

<wsu:Created>2013-02-22T18:32:02.204Z</wsu:Created>
</wsse:UsernameToken>
</wsse:Security>
</soapenv:Header>
<soapenv:Body>
<sch:getClient>
<getClientRequest>
<subscriberId>MY_SUBSCRIBER_ID</subscriberId>
<clientId>
<!--Optional:-->
<subscriberReferenceId>44XX33YY</subscriberReferenceId>
</clientId>
</getClientRequest>
</sch:getClient>
</soapenv:Body>
</soapenv:Envelope>
细节 3.每个 Fiddler,我失败的 SOAP 消息看起来像这样
<s:Envelope xmlns:s="http://schemas.xmlsoap.org/soap/envelope/" xmlns:u="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-utility-1.0.xsd">

<o:Security s:mustUnderstand="1" xmlns:o="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-secext-1.0.xsd">

</s:Header>
<s:Body xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
<getClient xmlns="schema.bancbox.com">
<getClientRequest xmlns="">
<subscriberId>MY_SUBSCRIBER_ID</subscriberId>
<clientId>

</clientId>
</getClientRequest>
</getClient>
</s:Body>
</s:Envelope>
上面的 SOAP 消息是在运行 GetClient() 方法时产生的。GetClient 引发以下异常。
System.ServiceModel.FaultException
Unmarshalling Error: cvc-elt.4.2: Cannot resolve 'getClientRequest' to a type definition for element 'getClientRequest'.
当我使用 SoapUI 重播相同的失败消息时,我得到以下响应:
<soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">
<soap:Body>
<soap:Fault>
<faultcode>soap:Client</faultcode>
<faultstring>Unmarshalling Error: cvc-elt.4.2: Cannot resolve 'getClientRequest' to a type definition for element 'getClientRequest'. </faultstring>
</soap:Fault>
</soap:Body>
</soap:Envelope>
细节 4.根据我的研究,这表明另一端的服务器是 Apache CXS。我的 SOAP 请求令人窒息。所以我开始玩弄我的 SOAP 消息并通过 SoapUI 提交它。
成功消息和我的失败消息中的第一个明显距离是这些行
成功
<sch:getClient>
<getClientRequest>
失败
<getClient xmlns="schema.bancbox.com">
<getClientRequest xmlns="">
所以我做的第一件事就是让我的 getClientRequest 标记与成功的标记相同。
<getClient xmlns="schema.bancbox.com">
<getClientRequest>
这产生了以下响应。
<soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">
<soap:Body>
<soap:Fault>
<faultcode>soap:Server</faultcode>
<faultstring>Found element {schema.bancbox.com}getClientRequest but could not find matching RPC/Literal part</faultstring>
</soap:Fault>
</soap:Body>
</soap:Envelope>
我做的下一件事是更改为 getClient 标记分配模式的方式。
前
<getClient xmlns="schema.bancbox.com">
后
<s:Envelope xmlns:bb="schema.bancbox.com" xmlns:s="http://schemas.xmlsoap.org/soap/envelope/" xmlns:u="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-utility-1.0.xsd">
. . .
<bb:getClient>
<getClientRequest>
. . .
</bb:getClient>
生成的 SOAP 消息如下所示,并且它是成功的。
<s:Envelope xmlns:bb="schema.bancbox.com" xmlns:s="http://schemas.xmlsoap.org/soap/envelope/" xmlns:u="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-utility-1.0.xsd">

所以百万美元的问题是为什么和如何。
*为什么 .NET 代理类以它的方式序列化 SOAP 消息?
*我如何解决它?我怎样才能将我的代理序列化为上面的 SOAP 消息?如何强制序列化程序为信封中的消息命名空间定义简写,然后在消息标签中使用简写?
仅供参考,为了达到这一点,我必须克服许多 WCF WSE 问题,并最终实施 Rich Stahls 博客上慷慨提供的解决方案。我会发布链接,但显然我没有足够的代表。
