WCF MaxReceivedMessageSize:超出最大邮件大小配额
Posted
技术标签:
【中文标题】WCF MaxReceivedMessageSize:超出最大邮件大小配额【英文标题】:WCF MaxReceivedMessageSize: maximum message size quota exceeded 【发布时间】:2010-12-07 02:43:18 【问题描述】:我收到此错误:
传入邮件的最大邮件大小配额 (65536) 已达到 超过。要增加配额,请使用 MaxReceivedMessageSize 相应绑定元素上的属性。
如何在 WCF 客户端应用程序或服务器应用程序中增加此值,如果可能,请举例说明如何做到这一点?
【问题讨论】:
【参考方案1】:你在客户端的 app/web.config 中增加它:
<system.serviceModel>
<bindings>
<basicHttpBinding>
<binding name="WSBigQuotaConfig" closeTimeout="00:01:00" openTimeout="00:01:00" receiveTimeout="00:10:00" sendTimeout="00:01:00" allowCookies="false" bypassProxyOnLocal="false" hostNameComparisonMode="StrongWildcard" maxBufferSize="2097152" maxBufferPoolSize="524288" maxReceivedMessageSize="2097152" messageEncoding="Text" textEncoding="utf-8" transferMode="Buffered" useDefaultWebProxy="true">
<readerQuotas maxDepth="32" maxStringContentLength="2097152" maxArrayLength="2097152" maxBytesPerRead="4096" maxNameTableCharCount="16384"/>
<security mode="None">
<transport clientCredentialType="None" proxyCredentialType="None" realm=""/>
<message clientCredentialType="UserName" algorithmSuite="Default"/>
</security>
</binding>
</basicHttpBinding>
</bindings>
<client>
<endpoint
address="http://example.com/endpoint.svc"
binding="basicHttpBinding"
bindingConfiguration="WSBigQuotaConfig"
contract="ISomeServiceContract" />
</client>
</system.serviceModel>
【讨论】:
+1 和 Accepted,但还值得一提的是,当传输模式 = buffered - maxBufferSize 和 maxReceivedMessageSize 应该包含相同的值...... maxBufferSize 和 maxReceivedMessageSize 不匹配会导致异常。【参考方案2】:您需要在绑定配置中设置 MaxReceivedMessageSize 属性。默认情况下,它是 65536。我假设您使用的数据集或类似性质的东西最终会非常大(主要是因为它们通常用 XML 表示)。
好消息是我认为您只需要在客户端配置中进行更改即可。看看下面。
<bindings>
<netTcpBinding>
<binding name="MyTcpBinding"
maxReceivedMessageSize="2000000"/>
</netTcpBinding>
<bindings>
【讨论】:
【参考方案3】:
<bindings>
<wsHttpBinding>
<binding name="wsHttpBinding_Username" maxReceivedMessageSize="20000000" maxBufferPoolSize="20000000">
<security mode="TransportWithMessageCredential">
<message clientCredentialType="UserName" establishSecurityContext="false"/>
</security>
</binding>
</wsHttpBinding>
</bindings>
<client>
<endpoint
binding="wsHttpBinding"
bindingConfiguration="wsHttpBinding_Username"
contract="Exchange.Exweb.ExchangeServices.ExchangeServicesGenericProxy.ExchangeServicesType"
name="ServicesFacadeEndpoint" />
</client>
