我遇到以下错误的问题:“已超出传入邮件的最大邮件大小限额(65536)。要增加配额,请在相应的绑定元素上使用MaxReceivedMessageSize属性。 “
所以我做了一些研究,发现我需要增加缓冲区和消息大小,这是我的WCF服务配置文件:
<system.serviceModel>
<bindings>
<wsHttpBinding>
<binding name="default" maxBufferPoolSize="2147483647" maxReceivedMessageSize="2147483647"/>
</wsHttpBinding>
</bindings>
<services>
<service name="WCF.Service.Service">
<endpoint address="ws" name="ws" bindingConfiguration="default" binding="wsHttpBinding" contract="WCF.Service.Contracts.IService" />
<endpoint address="mex" binding="mexHttpBinding" name="mex" contract="IMetadataExchange" />
</service>
</services>
<behaviors>
<serviceBehaviors>
<behavior>
<!-- To avoid disclosing metadata information,
set the value below to false and remove the metadata endpoint above before deployment -->
<serviceMetadata httpGetEnabled="True" />
<!-- To receive exception details in faults for debugging purposes,
set the value below to true. Set to false before deployment
to avoid disclosing exception information -->
<serviceDebug includeExceptionDetailInFaults="True" />
</behavior>
</serviceBehaviors>
</behaviors>
</system.serviceModel>
当我在WCF测试客户端中运行该服务并查看生成的客户端配置文件时,不拥有我的绑定:
<configuration>
<system.serviceModel>
<bindings>
<wsHttpBinding>
<binding name="ws" closeTimeout="00:01:00" openTimeout="00:01:00"
receiveTimeout="00:10:00" sendTimeout="00:01:00" bypassProxyOnLocal="false"
transactionFlow="false" hostNameComparisonMode="StrongWildcard"
maxBufferPoolSize="524288" maxReceivedMessageSize="65536"
messageEncoding="Text" textEncoding="utf-8" useDefaultWebProxy="true"
allowCookies="false">
<readerQuotas maxDepth="32" maxStringContentLength="8192" maxArrayLength="16384"
maxBytesPerRead="4096" maxNameTableCharCount="16384" />
<reliableSession ordered="true" inactivityTimeout="00:10:00"
enabled="false" />
<security mode="Message">
<transport clientCredentialType="Windows" proxyCredentialType="None"
realm="" />
<message clientCredentialType="Windows" negotiateServiceCredential="true"
algorithmSuite="Default" />
</security>
</binding>
</wsHttpBinding>
</bindings>
<client>
<endpoint address="http://localhost:37444/Service.svc/ws" binding="wsHttpBinding"
bindingConfiguration="ws" contract="IService" name="ws">
<identity>
<userPrincipalName value="username@domain" />
</identity>
</endpoint>
</client>
</system.serviceModel>
我迷失了为什么我的绑定配置 NOT 被应用了!? WCF测试客户端设置为始终重新生成配置。我也尝试在消费前端应用程序中更新服务引用,但不也获得更新的绑定配置。任何建议将不胜感激。谢谢!

WCF 不从您的服务器导入所有设置。也没有开关打开它。虽然在许多情况下它可能有意义,但是将服务器端的所有设置复制到客户端并不总是一个好主意。
因此,在您的情况下,您需要做的是将绑定配置添加到客户端代理,并从客户端端点引用它。
如果你控制电线的两端,你可以稍微简化你的工作:将绑定配置外部化为一个单独的文件并引用它。
所以创建一个包含以下内容的文件bindings.config
:
<?xml version="1.0" ?>
<bindings>
<wsHttpBinding>
<binding name="default"
maxBufferPoolSize="2147483647"
maxReceivedMessageSize="2147483647"/>
</wsHttpBinding>
</bindings>
然后您可以将该文件复制到服务器和客户端项目中,并从服务和客户端配置中引用它:
<system.serviceModel>
<bindings configSource="bindings.config" />
<services>
<service name="WCF.Service.Service">
<endpoint address="ws" name="ws" bindingConfiguration="default" binding="wsHttpBinding" contract="WCF.Service.Contracts.IService" />
<endpoint address="mex" binding="mexHttpBinding" name="mex" contract="IMetadataExchange" />
</service>
</services>
并在您的客户端:
<system.serviceModel>
<bindings configSource="bindings.config" />
<client>
<endpoint name="ws"
address="http://localhost:37444/Service.svc/ws"
binding="wsHttpBinding"
bindingConfiguration="default"
contract="IService">
<identity>
<userPrincipalName value="username@domain" />
</identity>
</endpoint>
</client>
</system.serviceModel>
这样,您可以对绑定进行一次配置,并在两个地方使用。

maxBufferPoolSize和maxReceivedMessageSize不会向客户端公开,只有服务器知道它们。客户端使用的大小是默认值,只需将它们更改为您想要的任何大小。显然这是有问题的,如果你正在重新生成它,但我不认为有很多替代方案。
