用web服务发送一个大阵列

Question

我看过很多解决方案来解决我的问题，但我没有找到对我有用的任何东西。

我的问题很简单：我无法通过webservice发送长字节数组。我可以发送一个代表4千字节但没有更大的图像的数组。

这是客户端配置

<configuration> 
     <system.serviceModel> 
      <bindings> 
       <basicHttpBinding> 
        <binding name="BasicHttpBinding_ICespitiAVService"        closeTimeout="02:00:00" 
       openTimeout="02:00:00" receiveTimeout="02:00:00" sendTimeout="02:00:00"   maxReceivedMessageSize="2147483647" maxBufferSize="2147483647" > 
         <security mode="None" /> 
        </binding> 
       </basicHttpBinding> 
      </bindings> 
      <client> 
       <endpoint address="http://localhost:51366/CespitiAVService.svc" 
      binding="basicHttpBinding" bindingConfiguration="BasicHttpBinding_ICespitiAVService" 
      contract="CespitiAVService.ICespitiAVService" name="BasicHttpBinding_ICespitiAVService"/> 
      </client> 
     </system.serviceModel> 
    </configuration> 

这是服务器配置

 <system.serviceModel> 
     <bindings> 
      <basicHttpBinding> 
      <binding name="BasicHttpBinding" maxBufferSize="2147483647" 
      maxReceivedMessageSize="2147483647"> 
       <readerQuotas maxDepth="2147483647" maxStringContentLength="2147483647" 
      maxArrayLength="2147483647" maxBytesPerRead="2147483647" 
      maxNameTableCharCount="2147483647" /> 
      </binding> 
      </basicHttpBinding> 
     </bindings> 
      <client /> 
      <behaviors> 
      <serviceBehaviors> 
       <behavior name=""> 
       <serviceMetadata httpGetEnabled="true" /> 
       <serviceDebug includeExceptionDetailInFaults="false" /> 
       <dataContractSerializer maxItemsInObjectGraph="655360"/> 
      </behavior> 
      </serviceBehaviors> 
      </behaviors> 
     <serviceHostingEnvironment multipleSiteBindingsEnabled="true" aspNetCompatibilityEnabled="true"/> 
     </system.serviceModel> 

哪里有人说把readerquotas也是在客户端的配置已经阅读解决方案，但XML赢得”不接受它，说它只接受安全节点。

有人说在客户端配置中更改transfermode会解决问题，但我只能使用缓冲模式，它不接受其他任何东西。

我用过fiddler，它说程序超过了maxarraylength，你可以看到我在web.config中改变了这个值，但是我不能在客户端配置中更改，因为它表示绑定节点没有readerquotas属性。

Answer 1

只是尝试创建新配置文件以下Maximum array length quota（解决我的问题），看看它是否解决您的问题或没有，因为我认为这个问题是由于您的配置文件。

我想你需要在客户端上设置DataContractSerializer的maxItemsInObjectGraph属性的端点行为配置。您还应该将readerQuotas添加到客户端的绑定配置中。这应该工作：

客户：

<behaviors> 
    <endpointBehaviors> 
    <behavior name="ICespitiAVService_Behavior"> 
     <dataContractSerializer maxItemsInObjectGraph="2147483647"/> 
    </behavior> 
    </endpointBehaviors> 
</behaviors> 
<bindings> 
    <basicHttpBinding> 
    <binding name="BasicHttpBinding_ICespitiAVService" closeTimeout="02:00:00" 
     openTimeout="02:00:00" receiveTimeout="02:00:00" sendTimeout="02:00:00" 
     maxBufferSize="2147483647" maxReceivedMessageSize="2147483647"> 
     <readerQuotas maxDepth="32" maxArrayLength="2147483647" /> 
     <security mode="None" /> 
    </binding> 
    </basicHttpBinding> 
</bindings> 
<client> 
    <endpoint address="http://localhost:51366/CespitiAVService.svc" 
    binding="basicHttpBinding" 
    bindingConfiguration="BasicHttpBinding_ICespitiAVService" 
    behaviorConfiguration="ICespitiAVService_Behavior" 
    contract="CespitiAVService.ICespitiAVService" 
    name="BasicHttpBinding_ICespitiAVService"/> 
    </endpoint> 
</client> 

服务器：

<bindings> 
    <binding name="LargeMessages" maxReceivedMessageSize="2147483647"> 
    <readerQuotas maxArrayLength="2147483647" maxDepth="32" /> 
    </binding> 
</bindings> 
<behaviors> 
    <serviceBehaviors> 
    <behavior name="ICespitiAVService.Behavior"> 
     <serviceMetadata httpGetEnabled="true" /> 
     <serviceDebug includeExceptionDetailInFaults="false" /> 
     <dataContractSerializer maxItemsInObjectGraph="2147483647" /> 
    </behavior> 
    </serviceBehaviors> 
</behaviors> 
<services> 
    <service behaviorConfiguration="ICespitiAVService.Behavior" name="ICespitiAVService"> 
    <endpoint address="" binding="basicHttpBinding" 
     contract="CespitiAVService.ICespitiAVService" 
     bindingConfiguration="LargeMessages"/> 
    <endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange" /> 
    <host> 
     <baseAddresses> 
     <add baseAddress="http://localhost:51366/" /> 
     </baseAddresses> 
    </host> 
    </service> 
</services>
