C＃WCF的Web阿比4 MaxReceivedMessageSize [英] C# WCF Web Api 4 MaxReceivedMessageSize

问题描述

我使用WCF的Web阿比4.0框架，并正在运行到maxReceivedMessageSize已经超过了65000错误。

我已经更新了我的webconfig看起来是这样，但因为我uisng的WCF的Web阿比我觉得这是不是即使再使用，因为我已经不再使用webHttpEndpoint？

 ＆LT; standardEndpoints＆GT;
      ＆LT; webHttpEndpoint＆GT;
        ＆LT;！ - 
            通过的global.asax.cs文件和默认端点配置WCF REST服务的基址
            经由上的＆lt属性; standardEndpoint＆GT;下面元
         - ＆GT;
        ＆LT; standardEndpoint NAME =
                          helpEnabled =真
                          automaticFormatSelectionEnabled =真
                          maxReceivedMessageSize =4194304/＆GT;

      ＆LT; / webHttpEndpoint＆GT;
 

我在哪里，在新的WCF的Web阿比指定MaxReceivedMessageSize？

我也尝试了CustomHttpOperationHandlerFactory无济于事：

 公共类CustomHttpOperationHandlerFactory：HttpOperationHandlerFactory
    {
        保护覆盖System.Collections.ObjectModel.Collection＆LT; HttpOperationHandler＆GT; OnCreateRequestHandlers（System.ServiceModel.Description.ServiceEndpoint终点，HttpOperationDescription操作）
        {
            VAR结合=（HttpBinding）endpoint.Binding;
            binding.MaxReceivedMessageSize = Int32.MaxValue;

            返回base.OnCreateRequestHandlers（端点操作）;
        }
    }
 

解决方案

如果你想（通过使用MapServiceRoute与HttpHostConfiguration.Create）的编程方式做到这一点，你做的是这样的：

  IHttpHostConfigurationBuilder httpHostConfiguration = HttpHostConfiguration.Create（）; //并添加任何配置的详细信息，你通常有

RouteTable.Routes.MapServiceRoute＆LT;为MyService，NoMessageSizeLimitHostConfig＆GT;（serviceUri分别，httpHostConfiguration）;
 

该NoMessageSizeLimitHostConfig是HttpConfigurableServiceHostFactory的扩展，它看起来是这样的：

 公共类NoMessageSizeLimitHostConfig：HttpConfigurableServiceHostFactory
{
    保护覆盖ServiceHost的CreateServiceHost（类型的serviceType，乌里[] baseAddresses）
    {
        VAR主机= base.CreateServiceHost（的serviceType，baseAddresses）;

        的foreach（在host.Description.Endpoints VAR端点）
        {
            VAR结合= endpoint.Binding为HttpBinding;

            如果（绑定！= NULL）
            {
                binding.MaxReceivedMessageSize = Int32.MaxValue;
                binding.MaxBufferPoolSize = Int32.MaxValue;
                binding.MaxBufferSize = Int32.MaxValue;
                binding.TransferMode = TransferMode.Streamed;
            }
        }
        返回主机;
    }
}
 

I am using the WCF Web Api 4.0 framework and am running into the maxReceivedMessageSize has exceeded 65,000 error.

I've updated my webconfig to look like this but because I am uisng the WCF Web Api I think this isn't even used anymore as I am no longer using a webHttpEndpoint?

<standardEndpoints>
      <webHttpEndpoint>
        <!-- 
            Configure the WCF REST service base address via the global.asax.cs file and the default endpoint 
            via the attributes on the <standardEndpoint> element below
        -->
        <standardEndpoint name="" 
                          helpEnabled="true" 
                          automaticFormatSelectionEnabled="true"
                          maxReceivedMessageSize="4194304" />       

      </webHttpEndpoint>

Where do I specify MaxReceivedMessageSize in the new WCF Web Api?

I've also tried a CustomHttpOperationHandlerFactory to no avail:

  public class CustomHttpOperationHandlerFactory: HttpOperationHandlerFactory
    {       
        protected override System.Collections.ObjectModel.Collection<HttpOperationHandler> OnCreateRequestHandlers(System.ServiceModel.Description.ServiceEndpoint endpoint, HttpOperationDescription operation)
        {
            var binding = (HttpBinding)endpoint.Binding;
            binding.MaxReceivedMessageSize = Int32.MaxValue;

            return base.OnCreateRequestHandlers(endpoint, operation);
        }
    }

解决方案

If you're trying to do this programatically (via using MapServiceRoute with HttpHostConfiguration.Create) the way you do it is like this:

IHttpHostConfigurationBuilder httpHostConfiguration = HttpHostConfiguration.Create(); //And add on whatever configuration details you would normally have

RouteTable.Routes.MapServiceRoute<MyService, NoMessageSizeLimitHostConfig>(serviceUri, httpHostConfiguration);  

The NoMessageSizeLimitHostConfig is an extension of HttpConfigurableServiceHostFactory that looks something like:

public class NoMessageSizeLimitHostConfig : HttpConfigurableServiceHostFactory
{
    protected override ServiceHost CreateServiceHost(Type serviceType, Uri[] baseAddresses)
    {
        var host = base.CreateServiceHost(serviceType, baseAddresses);  

        foreach (var endpoint in host.Description.Endpoints)
        {
            var binding = endpoint.Binding as HttpBinding;    

            if (binding != null)
            {
                binding.MaxReceivedMessageSize = Int32.MaxValue;
                binding.MaxBufferPoolSize = Int32.MaxValue;
                binding.MaxBufferSize = Int32.MaxValue;
                binding.TransferMode = TransferMode.Streamed;
            }
        }
        return host;
    }
}
