我在我的应用程序中使用 WCF。从应用程序我通过 WCF 传递一个列表以在后端处理。如果列表中的行数很大，则服务会抛出异常“远程服务器返回意外响应：(400) 错误请求。”

下面是我的 UI 网络配置

还将以下标记添加到 WCF Web 配置以及 UI Web 配置

<system.web>

      <httpRuntime maxRequestLength="512000" />

  </system.web>

我的服务配置如下

  <httpRuntime maxRequestLength="512000" />

服务模式：

<behaviors>
  <serviceBehaviors>
    <behavior>
      <serviceMetadata httpGetEnabled="true"/>
      <serviceDebug includeExceptionDetailInFaults="true"/>
    </behavior>
  </serviceBehaviors>
</behaviors>
<services>      
</services>
<serviceHostingEnvironment multipleSiteBindingsEnabled="true" />


<modules runAllManagedModulesForAllRequests="true"/>

我修改了服务 Web 配置 。我仍然遇到同样的问题。请帮助我

<services>

  <service name="BasicHttpBinding_IService1" behaviorConfiguration="Behavior">
    <endpoint address=""
              binding="basicHttpBinding"
              bindingConfiguration="BasicHttpBinding_IService1"
              contract="ServiceReference1.IService1"/>        
  </service>
  <service name="BasicHttpBinding_IErrorService" behaviorConfiguration="Behavior">
    <endpoint address=""
              binding="basicHttpBinding"
              bindingConfiguration="BasicHttpBinding_IErrorService"
              contract="ErrorServiceReference.IErrorService"/>

  </service>
  <service name="BasicHttpBinding_ISecurityUserService" behaviorConfiguration="Behavior">
    <endpoint address=""

              bindingConfiguration="BasicHttpBinding_ISecurityUserService"

您的服务配置中似乎没有定义任何端点或绑定，这意味着您正在获取默认端点和绑定。由于您的服务使用默认绑定及其默认值，因此它无法接收大消息。

您可以通过省略name绑定元素中的属性来覆盖默认绑定设置。但是，在您的情况下，您在三个定义的绑定中有不同的设置（至少在安全部分）。因此，您需要定义绑定并将它们分配给端点。

尝试这样的事情：

<bindings>
  <basicHttpBinding>
    <binding name="BasicHttpBinding_IService1" .....>
  </basicHttpBinding>
</bindings>

我省略了大部分绑定声明——你可以简单地从你的客户端配置中复制它们。

bindingConfig然后在服务中使用端点元素上的属性分配特定的绑定配置，如下所示：

<services>
  <service .... >
    <endpoint address="http://localhost:6789/Service1.svc"  
              binding="basicHttpBinding"
              bindingConfiguration="BasicHttpBinding_IService1" 
              contract="ServiceReference1.IService1" 
              name="BasicHttpBinding_IService1" />
  </service>
</services>

同样，为简单起见，我省略了大部分配置代码。

这里的关键点是服务需要有一个绑定，该绑定被配置为接受比默认值更大的消息。增加maxRequestLength运行时的值不会直接影响 WCF 服务（当然，除非您的请求大于 HTTP 运行时值）。
