Question

我正在尝试使用FW4.0构建WCF应用程序服务。在服务器和客户端之间传输EntiryFramework对象时，我的服务正常工作。但是我在将EF对象从客户端传递到服务器时遇到问题。

这里有一些关于我的环境的更多细节： - 该服务在IIS上以本地调试模式运行 - 我在Windows 7上运行所有这些 - 我在FW4.0上使用Visual Studio 2010

我正在尝试将一个对象（tblClient）发送到服务器以保存记录，但是一直有错误（413）请求实体太大。这里是完整的堆栈：

System.ServiceModel.ProtocolException occurred
      HResult=-2146233087

我做了一些研究，并指出maxBufferSize和/或maxBufferPoolSize和/或maxReceivedMessageSize在客户端配置App.Config中不够大。所以我把它们分解为最大价值： maxBufferSize =“2147483647”maxBufferPoolSize =“2147483647”maxReceivedMessageSize =“2147483647” 但仍然存在错误。

这是我的完整客户端App.Config

Any help would be very welcome :-)

Answer 1

记录

我想我明白了。来自服务的Web.Config没有绑定信息。我把这些信息放在里面，瞧！“

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

请注意，绑定没有指定名称。

Answer 2

您的服务没有明确的端点（意味着在配置文件中定义了端点），因此未使用您声明的绑定配置（“BasicHttpBinding_IService”）。 WCF提供默认端点以及默认绑定（basicHttpBinding，除非您在配置文件的protocolMapping部分覆盖它。）

您可以通过两种方法在服务的配置文件中解决此问题：

您可以通过删除name属性将“BasicHttpBinding_IService”配置设为默认值：

<binding maxBufferPoolSize="2147483647".....

或者您在配置中明确定义端点，并将绑定配置分配给端点的bindingConfiguration属性。

<services>
    <endpoint address="" 
              binding="basicHttpBinding"
              bindingConfiguration="BasicHttpBinding_IService"     
              contract="ServiceReference1.IService"  />
</services>

Answer 3

如果您创建自定义绑定，例如MybasicBinding，

  <basicHttpBinding>
      <binding name="MybasicBinding" closeTimeout="01:00:00" openTimeout="01:00:00" receiveTimeout="01:00:00" sendTimeout="01:00:00"
               maxBufferSize="2147483647" maxBufferPoolSize="2147483647" maxReceivedMessageSize="2147483647" >
            <readerQuotas maxDepth="32" maxBytesPerRead="200000000" 
             maxArrayLength="200000000" maxStringContentLength="200000000" />
      </binding>
  </basicHttpBinding>

要避免413错误，请不要预先为服务端点指定 bindingConfiguration =＆＃34; MybasicBinding＆＃34; ，

<endpoint address="" binding="basicHttpBinding" bindingConfiguration="MybasicBinding" contract="WCFService.IService" />

Answer 4

修复此问题并更好地了解web.config文件的另一种方法是使用＆＃34; Microsoft服务配置编辑器编辑web.config文件＆＃34; （C：\ Program Files（x86）\ Microsoft SDKs \ Windows \ v8.1A \ bin \ NETFX 4.5.1 Tools \ SvcConfigEditor.exe）

Answer 5

如果未指定绑定且httpsgetenabled为true，则可能需要在服务应用程序的web.config中设置basichttpsbinding

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

Answer 6

我收到此错误。我发现我已经创建了绑定配置，但是无法将端点设置为该配置。因此，端点使用的是默认设置的未命名绑定配置。因此，maxReceivedMessageSize为65k。

远程服务器返回了意外响应：（413）请求实体太大。
