Question

我以字符串格式从.net应用程序传递一些值给我的WCF服务。传递字符串格式将在此结构中，

ItemName~ItemDescription~ItemPrice|ItemName~ItemDescription~ItemPrice|...

每个订单项将以“|”分隔字符。我传递了近1000件物品。它按预期工作，但当我传递1500个项目时，会发生此错误。

The remote server returned an unexpected response: (413) Request Entity Too Large.

请帮我解决此错误。

这是服务中的方法

private void InsertGpLineItems(string lineItems)
{
    //Here I will process the insertion of line items to the GP system.
}

这是我的WCF服务上的 web.config 。

试试这个，

<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>

代替代码中的这些行，

<bindings>
  <basicHttpBinding>
    <binding name="SampleBinding" 
             messageEncoding="Text"
             closeTimeout="00:02:00"
             openTimeout="00:02:00"
             receiveTimeout="00:20:00"
             sendTimeout="00:02:00"
             allowCookies="false"
             bypassProxyOnLocal="false"
             hostNameComparisonMode="StrongWildcard"
             maxBufferPoolSize="2147483647" 
             maxBufferSize="2147483647"
             maxReceivedMessageSize="2147483647"
             textEncoding="utf-8"
             transferMode="Buffered"
             useDefaultWebProxy="true">          
      <readerQuotas maxDepth="2000000"
                    maxStringContentLength="2147483647"
                    maxArrayLength="2147483647"
                    maxBytesPerRead="2147483647"
                    maxNameTableCharCount="2147483647"  />
      <security mode="Transport">
        <transport clientCredentialType="None" 
                   proxyCredentialType="None" 
                   realm="">
        </transport>
      </security>
    </binding>        
  </basicHttpBinding>
</bindings>

我希望这会对你有所帮助。：）

它可能无法正常工作的一个原因是您的端点未使用已定义的绑定，因为您未通过bindingConfiguration中的endpoint属性指定它元件。这会导致WCF使用basicHttpBinding的默认值（较低），而不是您的值。

试试这个：

<service name="Service1.IService1">
  <endpoint address="" 
            binding="basicHttpBinding"
            bindingConfiguration="SampleBinding"
            contract="Service1.IService1">
  </endpoint>
  <host>
    <baseAddresses>
      <add baseAddress="http://localhost:50935/Service1.svc"/>
    </baseAddresses>
  </host>
  <!--<endpoint address="http://localhost:50935/Service1.svc" binding="basicHttpBinding"></endpoint>-->
</service>

请注意上面示例中bindingConfiguration属性的使用。

另请注意，如果您在IIS中托管服务，则不需要baseAddress元素，因为基地址将是.svc文件的位置。

同样的原则也适用于您的端点行为 - 它没有被分配给端点 - 您需要使用behaviorConfiguration属性：

<service name="Service1.IService1">
  <endpoint address=""
            behaviorConfiguration="behaviorGPLineItemsService"
            binding="basicHttpBinding"
            bindingConfiguration="SampleBinding"
            contract="Service1.IService" />

服务行为配置部分没有指定name属性，因此将其视为默认服务行为，并应用于未明确设置a的所有服务（在该配置文件中） behaviorConfiguration名称。

空白名称=默认也适用于绑定配置和端点行为配置，IIRC。

Answer 3

这是因为您的服务属于HTTP GET类型，其长度有限。

如果您发送的数据非常大，则必须改为使用HTTP POST。

[WebInvoke(Method = "POST")]
private void InsertGpLineItems(string lineItems)

此外，您需要编辑web.config文件，因为find here.

远程服务器返回意外响应：（413）请求实体太大。？
