WCF - 如何创建自定义的编程与通过HTTP二进制编码绑定（S） [英] WCF - how to create programatically custom binding with binary encoding over HTTP(S)

问题描述

我想转换我当前的HTTP / HTTPS的WCF绑定设置使用二进制消息编码和我需要做的是在code - 不是在XML配置。据我所知，有必要建立CustomBinding对象，并设置适当的BindingElements，但我无法弄清楚什么元素，我应该在我的情况下使用。

I'd like to convert my current HTTP/HTTPS WCF binding settings to use binary message encoding and I need to do it in code - not in XML configuration. AFAIK it's necessary to create CustomBinding object and set proper BindingElements, but I'm not able to figure out what elements should I use in my scenario.

在我的WCF配置要点是：

Main points in my WCF configuration are:

• 使用HTTP或HTTPS传输取决于配置（app.config中）


• 使用的用户名信息安全


• TODO：补充，而不是默认的文本二进制编码

我目前的code设置结合起来（的工作，但没有二进制编码）：

My current code for setting the binding up (working, but without the binary encoding):

var isHttps = Settings.Default.wcfServiceBaseAddress.StartsWith("https://", StringComparison.InvariantCultureIgnoreCase);
var binding = new WSHttpBinding(isHttps ? SecurityMode.TransportWithMessageCredential : SecurityMode.Message);
binding.Security.Message.ClientCredentialType = MessageCredentialType.UserName;

我尝试这个code，但它不工作 - 我不知道如何设置邮件安全元素的用户名信息的安全性：

I was trying this code, but it doesn't work - I don't know how to set message security element for username message security:

var custBinding = new CustomBinding();
custBinding.Elements.Add(new BinaryMessageEncodingBindingElement());
//Transport Security (Not Required)
if (isHttps)
{
    custBinding.Elements.Add(SecurityBindingElement.CreateUserNameForSslBindingElement());
}
//Transport (Required)
custBinding.Elements.Add(isHttps ?
    new HttpsTransportBindingElement() :
    new HttpTransportBindingElement());

任何人知道如何设置呢？我试图搜寻类似问题/溶液，但没有成功...

Anybody knows how to set this up? I tried to search for similar problem/solution, but didn't succeeded...

推荐答案

我几乎忘了这个问题，但这里是我这二进制绑定在HTTP上使用的用户名+密码验证，同时也能自定义绑定类允许打开的GZip COM $对... p $ pssion

I almost forgot this question, but here is my custom binding class which works with binary binding over HTTP with username+password validation and also allows to turn GZip compression on...

    public class CustomHttpBinding: CustomBinding
{
    private readonly bool useHttps;
    private readonly bool useBinaryEncoding;
    private readonly bool useCompression;
    private readonly HttpTransportBindingElement transport;

    public CustomHttpBinding(bool useHttps, bool binaryEncoding = true, bool compressMessages = false)
    {
        this.useHttps = useHttps;
        transport = useHttps ? new HttpsTransportBindingElement() : new HttpTransportBindingElement();
        useBinaryEncoding = binaryEncoding;
        useCompression = compressMessages;
    }

    public long MaxMessageSize{set
    {
        transport.MaxReceivedMessageSize = value;
        transport.MaxBufferSize = (int) value;
    }}

    public override BindingElementCollection CreateBindingElements()
    {
        BindingElement security;
        if (useHttps)
        {
            security = SecurityBindingElement.CreateSecureConversationBindingElement(
                SecurityBindingElement.CreateUserNameOverTransportBindingElement());
        }
        else
        {
            security = SecurityBindingElement.CreateSecureConversationBindingElement(
                SecurityBindingElement.CreateUserNameForSslBindingElement(true));
        }

        MessageEncodingBindingElement encoding;
        if (useCompression)
        {
            encoding = new GZipMessageEncodingBindingElement(useBinaryEncoding
                                                                ? (MessageEncodingBindingElement)
                                                                  new BinaryMessageEncodingBindingElement()
                                                                : new TextMessageEncodingBindingElement());
        }
        else
        {
            encoding = useBinaryEncoding
                        ? (MessageEncodingBindingElement) new BinaryMessageEncodingBindingElement()
                        : new TextMessageEncodingBindingElement();
        }

        return new BindingElementCollection(new[]
            {
                security,
                encoding,
                transport,
            });
    }
}
