[英]WCF - The maximum string content length quota (8192) has been exceeded while reading XML data
[英]WCF Config to fix The maximum string content length quota (8192) has been exceeded
我收到一个错误
超出最大字符串内容长度配额(8192)
我知道我需要修改WCF配置,但无法使其正常运行。 到目前为止,这是我所拥有的:我尝试使用内置的WCF编辑器。
<system.serviceModel>
<bindings>
<wsHttpBinding>
<binding>
<readerQuotas maxDepth="2147483647" maxStringContentLength="2147483647"
maxArrayLength="2147483647" maxBytesPerRead="2147483647" maxNameTableCharCount="2147483647" />
</binding>
</wsHttpBinding>
</bindings>
<client>
<remove contract="IMetadataExchange" name="sb" />
<endpoint address="" binding="netTcpRelayBinding" contract="IMetadataExchange"
name="sb" />
</client>
<services>
<service name="SvcLibrary.Service1">
<host>
<baseAddresses>
<add baseAddress="http://localhost:8732/Design_Time_Addresses/SvcLibrary/Service1/"/>
</baseAddresses>
</host>
<!-- Service Endpoints -->
<!-- Unless fully qualified, address is relative to base address supplied above -->
<endpoint address="" binding="wsHttpBinding" contract="SvcLibrary.IService1">
<!--
Upon deployment, the following identity element should be removed or replaced to reflect the
identity under which the deployed service runs. If removed, WCF will infer an appropriate identity
automatically.
-->
<identity>
<dns value="localhost"/>
</identity>
</endpoint>
<!-- Metadata Endpoints -->
<!-- The Metadata Exchange endpoint is used by the service to describe itself to clients. -->
<!-- This endpoint does not use a secure binding and should be secured or removed before deployment -->
<endpoint address="mex" binding="mexHttpBinding" 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="False"/>
</behavior>
</serviceBehaviors>
</behaviors>
</system.serviceModel>
SCB是正确的关于绑定的再次是:
<bindings>
<wsHttpBinding>
<binding>
<readerQuotas maxDepth="2147483647" maxStringContentLength="2147483647"
maxArrayLength="2147483647" maxBytesPerRead="2147483647" maxNameTableCharCount="2147483647" />
</binding>
</wsHttpBinding>
</bindings>
但是我也收到错误“超出最大字符串内容长度配额(8192)”,因为我需要按如下方式修改客户端应用程序:
<basicHttpBinding>
<binding name="BasicHttpBinding_IXRMService" closeTimeout="00:01:00"
openTimeout="00:01:00" receiveTimeout="00:10:00" sendTimeout="00:01:00"
allowCookies="false" bypassProxyOnLocal="false" hostNameComparisonMode="StrongWildcard"
maxBufferSize="65536" maxBufferPoolSize="524288" maxReceivedMessageSize="65536"
messageEncoding="Text" textEncoding="utf-8" transferMode="Buffered"
useDefaultWebProxy="true">
<readerQuotas maxDepth="32" maxStringContentLength="65536" maxArrayLength="16384"
maxBytesPerRead="4096" maxNameTableCharCount="16384" />
<security mode="None">
<transport clientCredentialType="None" proxyCredentialType="None"
realm="" />
<message clientCredentialType="UserName" algorithmSuite="Default" />
</security>
</binding>
</basicHttpBinding>
默认的maxStringContentLength设置为8192,我将其增加到65536,问题已解决。
您需要如下更改绑定部分:
<bindings>
<wsHttpBinding>
<binding maxReceivedMessageSize="2147483647">
<readerQuotas maxDepth="2147483647" maxStringContentLength="2147483647"
maxArrayLength="2147483647" maxBytesPerRead="2147483647" maxNameTableCharCount="2147483647" />
</binding>
</wsHttpBinding>
</bindings>
您的端点指定它正在使用wsHttpBinding,但是您仅配置了basicHttpBinding。
这意味着您的服务将仅使用默认值
顺便说一句,您指定的那些值巨大,您可能需要查看这些值
-更新
在绑定中添加了maxReceivedMessageSize属性。
您也可以确认是否在客户端进行了任何更改。 基本上,客户端和服务器配置都应该匹配。
您正在设置正确的属性( maxStringContentLength
),但是绑定错误。 问题在于您正在为basicHttpBinding
定义配置,但在服务端点上使用了wsHttpBinding
。 将绑定配置更改为wsHttpBinding
,它应该可以正常工作(您可能想验证是否需要通过wsHttpBinding
提供的WS- *功能,也可以将端点的绑定更改为basicHttpBinding
,只要您不这样做也可以使用需要支持分布式交易等)
