我目前有一个带有webHttp绑定的WCF服务,我试图通过覆盖config中的默认设置来增加可以输入到服务的最大大小,我尝试过像
这样的事情 <system.serviceModel>
<bindings>
<webHttpBinding>
<binding name="webHttp" >
<security mode="Transport">
<transport clientCredentialType =
"None"
proxyCredentialType="None"
realm="string" />
</security>
</binding>
</webHttpBinding>
</bindings>
<services>
<service name="PrimeStreamInfoServices.Service1" behaviorConfiguration="PrimeStreamInfoServices.Service1Behavior">
<!-- Service Endpoints -->
<endpoint address="" binding="webHttpBinding" contract="PrimeStreamInfoServices.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.
-->
</endpoint>
<endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange"/>
</service>
</services>
<behaviors>
<serviceBehaviors>
<behavior name="PrimeStreamInfoServices.Service1Behavior">
<!-- 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>
<diagnostics>
并设置与消息大小有关的各种其他属性但似乎没有工作,甚至可以更改webHttp绑定的消息大小? 有什么建议?谢谢!

根据您的设置,有许多设置可能会产生影响 - 请尝试以下操作:
<bindings>
<webHttpBinding>
<binding name="LargeWeb"
maxBufferPoolSize="1500000"
maxReceivedMessageSize="1500000"
maxBufferSize="1500000">
<readerQuotas
maxArrayLength="656000"
maxBytesPerRead="656000"
maxDepth="32"
maxNameTableCharCount="656000"
maxStringContentLength="656000"
/>
</binding>
</webHttpBinding>
</bindings>
通过定义webHttpBinding的“版本”并将所有这些参数设置为更高的值,您应该能够(几乎)通过任何消息大小。
请注意:这确实会让您的系统充满潜在的巨大信息,从而陷入困境(经典的拒绝服务攻击) - 这就是这些限制设置得相当低的原因 - 设计和目的。
您可以将它们更改为更高的值 - 只要知道您正在做什么以及安全风险是什么,如果您这样做了!

PS:为了使用这些设置,您当然必须在服务器和客户端配置中引用该绑定配置:
<client>
<endpoint address="http://localhost"
binding="webHttpBinding" bindingConfiguration="LargeWeb"
contract="IMyService" />
</client>
<services>
<service>
<endpoint address="http://localhost"
binding="webHttpBinding" bindingConfiguration="LargeWeb"
contract="IMyService" />
</service>
</services>

为WCF Rest服务设置最大消息和缓冲区大小webhttpbinding
<bindings>
<webHttpBinding>
<binding maxBufferPoolSize="2147483647" maxReceivedMessageSize="2147483647">
<readerQuotas maxDepth="200" maxStringContentLength="83886089" maxArrayLength="163841" maxBytesPerRead="2147483647" maxNameTableCharCount="16384"/>
</binding>
</webHttpBinding>
</bindings>

如果您在模型中使用[DataContract]装饰器,则需要在Web.config中添加 dataContractSerializer
示例:
<serviceBehaviors>
<behavior name="ServiceBehavior">
<serviceMetadata httpsGetEnabled="false" httpGetEnabled="true"/>
<serviceDebug includeExceptionDetailInFaults="true"/>
<dataContractSerializer maxItemsInObjectGraph="2147483647" />
</behavior>
</serviceBehaviors>
