WCF，已超过传入消息的最大消息大小配额(65536)

本文关键字：消息 65536 WCF | 更新日期: 2023-09-27 18:00:23

这个问题可能已经有了答案，但没有一个对我有效。我是WCF的新手，这是我工作的第一个项目。

我试过的答案：

已超过传入消息的最大消息大小配额（65536）

Wcf是否已超过传入邮件的最大邮件大小配额（65536）？

WCF错误-已超过传入消息的最大消息大小配额（65536）

我已经创建了一个项目，并在本地机器上成功运行。当我在IIS上发布并在Windows窗体应用程序下运行它时，我会收到以下错误：

已超过传入邮件的最大邮件大小配额（65536）。若要增加配额，请对相应的绑定元素使用MaxReceivedMessageSize属性。

这是我的服务器（WCF）web.config:

<?xml version="1.0"?>

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

这是我的客户（Winforms）app.config:

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
<system.web>
  <httpRuntime maxRequestLength="2147483647"/>
</system.web>

  </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">

      </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

WCF，已超过传入消息的最大消息大小配额(65536)

您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。

您可以在如下代码中设置maxReceivedMessageSize值：

binding.MaxReceivedMessageSize = 2147483647;

这使你的完整代码块这个：

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;

这应该是<httpRuntime maxRequestLength="32768"/>的问题。请尝试设置更大的值。
