为此我一直都在网上。我刚刚做了一段时间的魔鬼,而我试图消费的网络服务供应商拒绝正式支持WCF作为一种消费方式。
我不是网络服务专家,所以我会尽力记录并解释这篇文章,但是如果你需要的话,请务必提供更多信息,希望我能提供任何服务。是必要的。
服务
在我的公司,我们使用公开服务的供应商应用程序。该应用程序是用java编写的,看起来wsdl是用Apache Axis 1.2创建的。
代码
我的遗留代码使用WSE 3.0。特别是,它使用最后自动添加“WSE”的代理类。这允许我使用更简单的身份验证方案(我可以使它工作的唯一方法)。我不需要使用证书。我使用SecurityPolicyAssertion
的派生,并将其包装在Policy
对象中,该对象将传递给客户端类的SetPolicy
方法。以下是创建客户端工作实例所需的全部内容:
MyWebServiceWse api = new MyWebServiceWse();
api.Url = myUrl;
api.SetPolicy(new Policy(new MyDerivedSecurityAssertion(user, pass)));
我的默认,WCF的开箱即用代码(使用服务引用生成)不接受凭据,因此我知道现在有问题。我已经在线阅读了有关在security
中使用不同app.config
或绑定设置的各种内容,但没有任何内容完全奏效。经过大量修补后,我最常见的错误是WSDoAllReceiver: Request does not contain required Security header
。
这是app.config。也许我们可以先告诉我这里应该改变什么来促进传递证书 - 再次,我在网上看到了不同的意见。

我更改了一些属性,以掩盖我们正在使用的特定服务(公司政策及所有这些)。
以下是目前为止的示例C#代码(在控制台应用程序中测试):
MyClient client = new MyClient();
client.listMethod();
更新
阅读此SO帖子:wcf security . . .。
我已相应更新了我的app.config,现在正在代码中传递用户名和密码。我仍然收到同样的错误:
WSDoAllReceiver: Request does not contain required Security header

20120518更新 我已经尝试在Mike Miller在评论中链接的帖子中实现解决方案。现在我收到以下错误(没有消息最终被发送,因为有些东西正在计划中):
The provided URI scheme 'http' is invalid; expected 'https'.
如果有人想问,是的,我需要通过http发送,是的,我知道凭据是以未加密的字符串形式发送的: - )
答案 0 :(得分:11)
您需要的是通过http传输发送用户名令牌,这在wcf ootb中不受支持。此外,您的令牌使用nonce / created,这也不是ootb。你有两个选择:
此oss project将nonce / created添加到用户名令牌。此oss project添加了通过http发送用户名的功能。你需要将两个项目结合起来。
ws-security通常被认为是复杂的,但您以最简单的形式(用户名)使用它。最简单的方法是将所有wcf安全设置一起解除,并在message inspector中自己创建整个安全标头!正如您所看到的,大多数标头只是静态xml节点,并且大多数值非常清楚(您知道用户名)。唯一棘手的两个是nonce和时间戳,你可以在这个oss project看看如何做(每行一行)。这个选项的变体可能更容易 - 毕竟使用CUB并实现推送timestmpa / nonce的custom encoder。我会选择后者但是因为我开发了CUB而我有偏见......
您还可以在自定义编码“messageVersion”属性上配置ws-addressing标头。由于您省略了带有wsa前缀定义的信封标题,我无法确切地说出确切的值。
如果您私下想要帮助(因为您似乎有安全限制),请通过my blog向我发送电子邮件。
编辑:我已经为你实现了它。请按照以下步骤操作:下载cub并熟悉它(不是内部,根据博客文章如何使用它)
将System.Runtime.Serialization.dll的引用添加到项目ClearUsernameBinding
向该项目添加一个新文件:UsernameExEncoder.cs。粘贴此内容:

this.inner.MessageVersion = value;

var mem = new MemoryStream();
var x = XmlWriter.Create(mem);

x.Flush();
mem.Flush();
mem.Position = 0;
XmlDocument doc = new XmlDocument();
doc.Load(mem);
//add the missing elements
var token = doc.SelectSingleNode("//*[local-name(.)='UsernameToken']");
var created = doc.CreateElement("Created", "http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-secext-1.0.xsd");

}
public override void WriteMessage(Message message, System.IO.Stream stream)
{
this.inner.WriteMessage(message, stream);
}
}
}
在ClearUsernameBinding.cs文件中替换为:
res.Add(new TextMessageEncodingBindingElement() { MessageVersion = this.messageVersion});
用这个:
var textEncoder = new TextMessageEncodingBindingElement() { MessageVersion = this.messageVersion };
res.Add(new UsernameExEncoderBindingElement(textEncoder));
在app.config中的项目TestClient中,绑定元素上有一个messageVersion属性。您尚未发布信封的根目录,因此我无法确定,但您可能需要将其设置为Soap11WSAddressingAugust2004或Soap11WSAddressing10(或其中一个使用Soap12)。
