WCF，已超过传入消息的最大消息大小配额 (65536)

Question

这个问题可能已经有了答案，但 none 对我有用。我是 WCF 的新手，这是我工作的第一个项目。

我试过的答案：

The maximum message size quota for incoming messages (65536) has been exceeded

Wcf-The maximum message size quota for incoming messages (65536) has been exceeded?

WCF Error - The maximum message size quota for incoming messages (65536) has been exceeded

我已经创建了一个项目，并且运行在本地机器上成功了。当我在 IIS 上发布它并在 Windows 表单应用程序下运行时，我收到此错误：

The maximum message size quota for incoming messages (65536) has been exceeded. To increase the quota, use the MaxReceivedMessageSize property on the appropriate binding element.

这是我的服务器 (WCF) web.config:

<?xml version="1.0"?>
<configuration>
   <appSettings>
      <add key="connectionString" value="data source=localhost; initial catalog=TWO; integrated security=SSPI"/>

    <serviceHostingEnvironment multipleSiteBindingsEnabled="true" />
</system.serviceModel>
<system.webServer>
  <modules runAllManagedModulesForAllRequests="true"/>

</configuration>

这是我的客户端 (Winforms) app.config:

<?xml version="1.0" encoding="utf-8" ?>
<configuration>

<system.web>
  <httpRuntime maxRequestLength="2147483647"/>
</system.web>

<system.serviceModel>
  <client>
    <endpoint address="http://192.168.0.60/Service1.svc" binding="basicHttpBinding"
      bindingConfiguration="BasicHttpBinding_IService1" contract="GPLineItemsService.IService1"
      name="BasicHttpBinding_IService1" />
  </client>

  <bindings>
  <basicHttpBinding>
    <binding name="BasicHttpBinding_IService1" maxBufferPoolSize="2147483647" maxBufferSize="2147483647" maxReceivedMessageSize="2147483647" messageEncoding="Text">
      <readerQuotas maxDepth="2000000" maxStringContentLength="2147483647" maxArrayLength="2147483647" maxBytesPerRead="2147483647" maxNameTableCharCount="2147483647" />
    </binding>
  </basicHttpBinding>
</bindings>

  <behaviors>
    <endpointBehaviors>
      <behavior name="GpWebServiceBehavior">
        <dataContractSerializer maxItemsInObjectGraph="2147483647"/>
      </behavior>
    </endpointBehaviors>
  </behaviors>

</system.serviceModel>
</configuration>

这是我用来调用服务的客户端代码。

EndpointAddress address = new EndpointAddress(GPWCFEndPointAddress);
BasicHttpBinding binding = new BasicHttpBinding();
GPLineItemsService.Service1Client gpService = new GPLineItemsService.Service1Client(binding, address);
GPLineItemsService.GPItems gpItems = new GPLineItemsService.GPItems();
gpItems = gpService.InsertUpdateLineItemsInGP(dtGPItems);
opResult = gpItems.ErrorGPItems;

非常感谢您的帮助。谢谢。

Answer 1

这应该是问题所在<httpRuntime maxRequestLength="32768"/>尝试设置一个更大的值。

Answer 2

您是在代码中创建自己的绑定，而不是使用配置文件中指定的绑定，因此您在应用程序配置文件中所做的任何更改基本上都会被忽略。

您可以像这样在代码中设置 maxReceivedMessageSize 值：

binding.MaxReceivedMessageSize = 2147483647;

这使得您的完整代码块如下：

EndpointAddress address = new EndpointAddress(GPWCFEndPointAddress);
BasicHttpBinding binding = new BasicHttpBinding();
binding.MaxReceivedMessageSize = 2147483647;
GPLineItemsService.Service1Client gpService = 
    new GPLineItemsService.Service1Client(binding, address);
GPLineItemsService.GPItems gpItems = new GPLineItemsService.GPItems();
gpItems = gpService.InsertUpdateLineItemsInGP(dtGPItems);
opResult = gpItems.ErrorGPItems;

或者，您可以使用配置文件中指定的绑定和端点：

GPLineItemsService.Service1Client gpService = new GPLineItemsService.Service1Client();
GPLineItemsService.GPItems gpItems = new GPLineItemsService.GPItems();
gpItems = gpService.InsertUpdateLineItemsInGP(dtGPItems);
opResult = gpItems.ErrorGPItems;
