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。

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。
答案 1 :(得分：12)
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>
答案 2 :(得分：0)
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" />

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）
答案 4 :(得分：0)
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>
答案 5 :(得分：0)
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。
