我已经在这里搜索了所有可用的问题,我不知道问题是否特定于我的配置,或者我是否遗漏了某些内容。
背景:
我有一个使用 HTTPS 绑定(bind)托管在 IIS 7 上的 WCF 服务。该服务用于发送/接收大型对象。 Windows 服务使用此 WCF 服务将这些大对象发送给它,但我收到 400 Bad Request 错误。我已在服务中启用跟踪,错误是“已超出传入消息的最大消息大小配额 (65536)”。下面是WCF和Windows服务的配置以及WCF服务的使用方式。
WCF 服务配置。

该服务通过具有以下配置的 Windows 服务使用:
<system.web>
<httpRuntime maxRequestLength="2147483647" />
</system.web>
<system.serviceModel>
<bindings>
<webHttpBinding>
<binding name="basicWebHttp" allowCookies="true" closeTimeout="00:59:59" receiveTimeout="00:59:59"
sendTimeout="00:59:59"
maxReceivedMessageSize="2147483647" maxBufferSize="2147483647" maxBufferPoolSize="2147483647">
<readerQuotas maxDepth="2147483647" maxStringContentLength="2147483647" maxArrayLength="2147483647"
maxBytesPerRead="2147483647" maxNameTableCharCount="2147483647" />
<security mode="Transport">
<transport clientCredentialType="None"></transport>
</security>
</binding>
</webHttpBinding>
</bindings>
<behaviors>
<endpointBehaviors>
<behavior name="basicWebHttpBehaviour">
<dataContractSerializer maxItemsInObjectGraph="2147483647" />
<webHttp />
</behavior>
</endpointBehaviors>
</behaviors>
<client>
<endpoint address="" behaviorConfiguration="basicWebHttpBehaviour"
binding="webHttpBinding" bindingConfiguration="basicWebHttp"
contract="labis.IVisService" name="BasicHttpBinding_IVisService" />
</client>
<serviceHostingEnvironment multipleSiteBindingsEnabled="true" />
</system.serviceModel>
该服务的调用方式如下:
System.Net.ServicePointManager.ServerCertificateValidationCallback += (se, cert, chain, sslerror) => { return true; };
WebChannelFactory<IVisService> factory = new WebChannelFactory<IVisService>(
"BasicHttpBinding_IVisService",
new Uri("https://some_ip/service.svc"));
IVisService service = factory.CreateChannel();
service.PostData(large_object);
我已经启用了跟踪,从日志中我可以看到服务器抛出了异常: 已超出传入消息的最大消息大小配额 (65536)
我想我已经设置了它工作所需的所有属性,但运气不佳。 另外,在 IIS 配置编辑器中,我已将 system.webServer/security/requestFiltering - requestLimits 属性设置为最大值
有什么帮助吗?
谢谢:)

我粘贴了错误的端点配置元素。原始版本缺少behaviorConfiguration =“WebHttp”部分,但我已经使用包含此属性对其进行了测试。
最佳答案
在尝试了所有可能性之后,解决方案非常简单。 我在WCF服务中添加了以下配置
<protocolMapping>
<add scheme="https" binding="webHttpBinding" bindingConfiguration="basicWebHttp" />
<add scheme="http" binding="webHttpBinding" bindingConfiguration="basicWebHttp" />
</protocolMapping>
在此处了解更多信息 http://msdn.microsoft.com/en-us/library/ee816881.aspx
我猜这是可行的,因为该服务使用 HTTPS 绑定(bind),因此它需要绑定(bind)的显式映射。
至少这对我有用
