WCF服务：远程服务器返回了意外的响应：（400）错误的请求

我有一个WCF服务，当小数据必须通过线路传输时，它的工作效果很好。当我增加数据到一个更大的尺寸，我得到以下错误：WCF服务：远程服务器返回了意外的响应：（400）错误的请求

The remote server returned an unexpected response: (400) Bad Request.

我知道这个问题已被问了很多次是其他用户。但是，我尝试了所有这些方法来解决这个问题。没有什么是为我工作的。你能看看我的配置内容，并让我知道如果我失去了一些东西。以下是我的服务的配置文件。

<?xml version="1.0" encoding="utf-8" ?> 
<configuration> 
    <appSettings> 
    <add key="aspnet:UseTaskFriendlySynchronizationContext" value="true" /> 
    </appSettings> 
    <system.web> 
    <compilation debug="true" /> 
    </system.web> 
    <!-- When deploying the service library project, the content of the config file must be added to the host's 
    app.config file. System.Configuration does not support config files for libraries. --> 
    <system.serviceModel> 
    <services> 
     <service name="RecieveValidationResultHubServiceLibrary.ReceiveValidationResultHubService"> 
     <endpoint address="" binding="basicHttpBinding" contract="RecieveValidationResultHubServiceLibrary.IReceiveValidationResultHubService"> 
      <identity> 
      <dns value="localhost" /> 
      </identity> 
     </endpoint> 
     <endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange" /> 
     <host> 
      <baseAddresses> 
      <add baseAddress="http://localhost:8735/Design_Time_Addresses/RecieveValidationResultHubServiceLibrary/ReceiveValidationResultHubService/" /> 
      </baseAddresses> 
     </host> 
     </service> 
    </services> 
    <behaviors> 
     <serviceBehaviors> 
     <behavior> 
      <!-- To avoid disclosing metadata information, 
      set the values below to false before deployment --> 
      <serviceMetadata httpGetEnabled="True" httpsGetEnabled="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> 
</configuration>

以下是服务引用的配置：

如果知道您尝试了哪些“修复”，这样会很有帮助，因此我们不会在相同的大雁追逐中结束。 –

您可能需要按照[此处]（http://stackoverflow.com/questions/884235/wcf-how-to-increase-message-size-quota）的说明放大消息大小配额。 – venerik

我曾尝试： maxBufferPoolSize = “2000000” maxReceivedMessageSize = “2000000” maxStringContentLength = “2000000” 的MaxArrayLength = “2000000” 在两个CONFIGS。但是，没有为我工作。 –

如果误差约为最大读者配额，请让你的下结合web.config中的变化。看看它是否有效。

<binding maxBufferSize="2147483647" maxReceivedMessageSize="2147483647"> 
     <readerQuotas maxDepth="32" maxStringContentLength="2147483647" 
     maxArrayLength="16348" maxBytesPerRead="4096" maxNameTableCharCount="16384" /> 
</binding>

我现在的客户端的配置文件看起来是这样的： <绑定名称= “BasicHttpBinding_IReceiveValidationResultHubService” maxBufferPoolSize = “2147483647” maxReceivedMessageSize = “2147483647” MAXBUFFERSIZE = “2147483647” transferMode = “流”> 我仍然不知道在哪里把这些最大PARAMS在我的服务的配置文件。 –

在你的web.config文件中，有标签，里面有标签。在标记中使用此代码。 – Aki
