WCF，已超出传入邮件的最大邮件大小配额 (65536)

Question

这个问题可能已经有了答案，但没有一个对我有用。我对 WCF 很陌生，这是我正在工作的第一个项目。

我尝试过的答案：

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 上发布它并在 Windows 窗体应用程序下运行它时，我收到此错误：

已超出传入邮件的最大邮件大小配额 (65536)。要增加配额，请在适当的绑定元素上使用 MaxReceivedMessageSize 属性。

这是我的服务器 (WCF) web.config:

这是我的客户（Winforms）app.config:

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;

您的所有帮助将不胜感激。谢谢。

Answer 1

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都会被忽略。

您可以像这样在代码中设置maxReceivedMessageSize 值：

binding.MaxReceivedMessageSize = 2147483647;

这会让你的完整代码阻塞：

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;

Answer 2

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