如何在不使用 app.config 的情况下在 WCF 绑定中设置正确的内容类型？

Question

我从测试控制台应用程序创建了对 CRM 2011 Organization.svc 的服务引用。 使用 app.config 中生成的绑定可以完美运行。（Microsoft here 托管的服务示例。）

现在需要将其移动到我们的“真实”应用程序中并托管在将部署到 GAC 的 DLL 中。在遵循应用程序的约定时，绑定需要由代码生成。

我已经开始尝试使用我们用于其他 WCF 服务的绑定：

BasicHttpBinding binding = new BasicHttpBinding();
binding.SendTimeout = TimeSpan.FromMinutes(1);
binding.OpenTimeout = TimeSpan.FromMinutes(1);
binding.CloseTimeout = TimeSpan.FromMinutes(1);
binding.ReceiveTimeout = TimeSpan.FromMinutes(10);
binding.AllowCookies = true;
binding.BypassProxyOnLocal = false;
binding.HostNameComparisonMode = HostNameComparisonMode.StrongWildcard;
binding.MessageEncoding = WSMessageEncoding.Text;
binding.TextEncoding = System.Text.Encoding.UTF8;
binding.TransferMode = TransferMode.Buffered;
binding.UseDefaultWebProxy = true;
binding.Security.Mode = BasicHttpSecurityMode.TransportCredentialOnly;
binding.Security.Transport.ClientCredentialType = HttpClientCredentialType.Windows;

不幸的是，在调用 WCF 服务时（使用带有 OrganizationRequest 的 Execute 方法），出现此错误：

System.ServiceModel.ProtocolException: 内容类型 text/xml;服务 http://server:5555/xrmservices/2011/organization.svc 不支持 charset=utf-8。客户端和服务绑定可能不匹配。

我不确定绑定的具体问题是什么，但到目前为止，我尝试将其转换为代码的尝试都失败了，并出现了同样的错误。这是 app.config 中定义的工作绑定：

<bindings>
    <customBinding>
        <binding name="CustomBinding_IOrganizationService">

                useDefaultWebProxy="true" />
        </binding>
    </customBinding>
</bindings>

有谁知道如何在代码中设置正确的绑定和/或从 XML 读取绑定？

我只是有同样的任务要解决。这对我有用（对于http）。

var security = SecurityBindingElement.CreateSspiNegotiationBindingElement();
security.DefaultAlgorithmSuite = SecurityAlgorithmSuite.Default;
security.SecurityHeaderLayout = SecurityHeaderLayout.Strict;
security.IncludeTimestamp = true;
security.KeyEntropyMode = SecurityKeyEntropyMode.CombinedEntropy;
security.MessageProtectionOrder = MessageProtectionOrder.SignBeforeEncryptAndEncryptSignature;
security.MessageSecurityVersion = MessageSecurityVersion.WSSecurity11WSTrustFebruary2005WSSecureConversationFebruary2005WSSecurityPolicy11BasicSecurityProfile10;

security.LocalClientSettings.CacheCookies = true;
security.LocalClientSettings.DetectReplays = true;
security.LocalClientSettings.ReplayCacheSize = 900000;
security.LocalClientSettings.MaxClockSkew = new TimeSpan(0, 5, 0);
security.LocalClientSettings.MaxCookieCachingTime = new TimeSpan(23, 0, 0, 0);
security.LocalClientSettings.ReplayWindow = new TimeSpan(0, 5, 0);
security.LocalClientSettings.SessionKeyRenewalInterval = new TimeSpan(15, 0, 0);
security.LocalClientSettings.SessionKeyRolloverInterval = new TimeSpan(0, 5, 0);
security.LocalClientSettings.ReconnectTransportOnFailure = true;
security.LocalClientSettings.TimestampValidityDuration = new TimeSpan(0, 5, 0);
security.LocalClientSettings.CookieRenewalThresholdPercentage = 60;

security.LocalServiceSettings.DetectReplays = true;
security.LocalServiceSettings.IssuedCookieLifetime = new TimeSpan(10, 0, 0);
security.LocalServiceSettings.MaxStatefulNegotiations = 128;
security.LocalServiceSettings.ReplayCacheSize = 900000;
security.LocalServiceSettings.MaxClockSkew = new TimeSpan(0, 5, 0);
security.LocalServiceSettings.NegotiationTimeout = new TimeSpan(0, 1, 0);
security.LocalServiceSettings.ReplayWindow = new TimeSpan(0, 5, 0);
security.LocalServiceSettings.InactivityTimeout = new TimeSpan(0, 2, 0);
security.LocalServiceSettings.SessionKeyRenewalInterval = new TimeSpan(15, 0, 0);
security.LocalServiceSettings.SessionKeyRolloverInterval = new TimeSpan(0, 5, 0);
security.LocalServiceSettings.ReconnectTransportOnFailure = true;
security.LocalServiceSettings.MaxPendingSessions = 128;
security.LocalServiceSettings.MaxCachedCookies = 1000;
security.LocalServiceSettings.TimestampValidityDuration = new TimeSpan(0, 5, 0);

var textEncoding = new TextMessageEncodingBindingElement
{
   MaxReadPoolSize = 64,
   MaxWritePoolSize = 16,
   MessageVersion = MessageVersion.Default,
   WriteEncoding = System.Text.Encoding.UTF8,
   ReaderQuotas = new XmlDictionaryReaderQuotas
   {
       MaxDepth = 32,
       MaxArrayLength = 16384,
       MaxBytesPerRead = 4096,
       MaxNameTableCharCount = 16384,
       MaxStringContentLength = 8192
   }
};

var httpTransport = new HttpTransportBindingElement
{
    ManualAddressing = false,
    MaxBufferSize = 65536,
    MaxReceivedMessageSize = 65536,
    AllowCookies = false,
    AuthenticationScheme = AuthenticationSchemes.Anonymous,
    BypassProxyOnLocal = false,
    DecompressionEnabled = true,
    HostNameComparisonMode = HostNameComparisonMode.StrongWildcard,
    KeepAliveEnabled = true,
    MaxBufferPoolSize = 524288,
    ProxyAuthenticationScheme = AuthenticationSchemes.Anonymous,
    TransferMode = TransferMode.Buffered,
    UnsafeConnectionNtlmAuthentication = false,
    UseDefaultWebProxy = true,
};

var binding = new CustomBinding(new List<BindingElement> { security, textEncoding, httpTransport });
var endpoint = new EndpointAddress(_serviceUri);

var service = new OrganizationServiceClient(binding, endpoint);

创建自定义渠道工厂是解决此问题的关键部分。

Get your WCF client configuration from anywhere 文章对于使用自定义服务客户端从您选择的位置读取 .config 文件非常有帮助。

Calling WCF Service using Client Channel Factory 中描述了以与 app.config 格式非常相似的方式设置所有值的替代方法，它描述了如何创建自定义绑定。我发现并不是所有的安全属性都可以这样设置（或者至少我找不到它们）。
