WCF - 如何增加邮件大小配额-Java 学习之路

429

我有一个WCF服务，它从数据库向客户端返回1000条记录 . 我有一个ASP.NET WCF客户端（我在asp.net Web应用程序项目中添加了服务引用以使用WCF） .

运行客户端应用程序时收到以下消息：

已超出传入邮件的最大邮件大小限额（65536） . 要增加配额，请在相应的绑定元素上使用MaxReceivedMessageSize属性 .

有帮助吗？如何增加邮件大小配额？

您需要这样的东西来增加App.config或Web.config文件中的邮件大小配额：
```
<bindings>
    <basicHttpBinding>
        <binding name="basicHttp" allowCookies="true"
                 maxReceivedMessageSize="20000000" 
                 maxBufferSize="20000000"
                 maxBufferPoolSize="20000000">
            <readerQuotas maxDepth="32" 
                 maxArrayLength="200000000"
                 maxStringContentLength="200000000"/>
        </binding>
    </basicHttpBinding>
</bindings>
```
并在 endpoints 配置中使用绑定名称，例如
```
...
bindingConfiguration="basicHttp"
...
```
值的理由很简单，它们足够大以容纳大多数消息 . 您可以调整该数字以满足您的需求 . 低默认值基本上是为了防止DOS类型攻击 . 使其成为20000000将允许分布式DOS攻击有效，默认大小为64k将需要大量客户端来支持大多数服务器 .

如果你're still getting this error message while using the WCF Test Client, it'因为客户端有一个单独的 MaxBufferSize 设置 .

To correct the issue:
- 右键单击树底部的 Config File 节点
- 选择使用SvcConfigEditor编辑
将显示可编辑设置列表，包括MaxBufferSize .

Note: 默认情况下，自动生成的代理客户端还将MaxBufferSize设置为65536 .

如果要动态创建WCF绑定，请使用以下代码：

BasicHttpBinding httpBinding = new BasicHttpBinding();
httpBinding.MaxReceivedMessageSize = Int32.MaxValue;
httpBinding.MaxBufferSize = Int32.MaxValue;
// Commented next statement since it is not required
// httpBinding.MaxBufferPoolSize = Int32.MaxValue;

WCF Test Client 拥有自己的客户端配置 .

运行测试客户端并滚动到底部 . 如果双击“配置文件”节点，您将看到XML表示 . 如您所见， maxReceivedMessageSize 是 65536 .

要编辑它，请右键单击“配置文件”树节点，然后选择“使用 SvcConfigEditor 编辑” . 编辑器打开时展开Bindings并双击自动生成的绑定 .

您可以在此处编辑所有属性，包括 maxReceivedMessageSize . 完成后，单击文件 - 保存 .

最后，当您返回WCF测试客户端窗口时，单击工具 - 选项 .

NOTE ：取消选中启动服务时始终重新生成配置 .

我找到了简单的方法

---右键单击webconfig或app配置文件，然后单击EDIT WCF CONFIGURATION，然后选择bingdigs和选择yore服务，右侧显示maxReciveMessageSize给出一个大数字---

我在我的项目中使用CalculateRoute（）在Bing Maps WPF上解决了我的问题 . 我的解决方案是在“customBinding”部分的属性“httpTransport”上设置maxReceivedMessageSize和maxReceivedMessageSize .

我在applications.config文件（es.myApp.config）中设置了这个配置：

<system.serviceModel>
    <bindings>
        <basicHttpBinding>
            <binding name="BasicHttpBinding_IGeocodeService" />
            <binding name="BasicHttpBinding_IRouteService" />
        </basicHttpBinding>
        <customBinding>
            <binding name="CustomBinding_IGeocodeService">
                <binaryMessageEncoding />
              <httpTransport manualAddressing="false" maxBufferPoolSize="524288"
                                maxReceivedMessageSize="2147483647" allowCookies="false" authenticationScheme="Anonymous"
                                bypassProxyOnLocal="false" decompressionEnabled="true" hostNameComparisonMode="StrongWildcard"
                                keepAliveEnabled="true" maxBufferSize="2147483647" proxyAuthenticationScheme="Anonymous"
                                realm="" transferMode="Buffered" unsafeConnectionNtlmAuthentication="false"
                                useDefaultWebProxy="true" />
            </binding>
            <binding name="CustomBinding_IRouteService">
                <binaryMessageEncoding />
              <httpTransport manualAddressing="false" maxBufferPoolSize="524288"
                                maxReceivedMessageSize="2147483647" allowCookies="false" authenticationScheme="Anonymous"

                                realm="" transferMode="Buffered" unsafeConnectionNtlmAuthentication="false"
                                useDefaultWebProxy="true" />
            </binding>
        </customBinding>
    </bindings>

Another important thing to consider from my experience..

我强烈建议不要最大化maxBufferPoolSize，因为池中的缓冲区永远不会释放，直到app-domain（即应用程序池）循环使用 .

高流量时段可能会导致大量内存被使用而且从未被释放 .

不要忘记执行入口点的app.config将被考虑，而不是管理Web服务调用的类库项目中的那个（如果有） .

例如，如果在运行单元测试时遇到错误，则需要在测试项目中设置适当的配置 .

对我来说，我所要做的就是将 maxReceivedMessageSize="2147483647" 添加到客户端app.config中 . 服务器没有动过 .

对于 HTTP:

<bindings>
  <basicHttpBinding>
    <binding name="basicHttp" allowCookies="true"
             maxReceivedMessageSize="20000000" 
             maxBufferSize="20000000"
             maxBufferPoolSize="20000000">
        <readerQuotas maxDepth="200" 
             maxArrayLength="200000000"
             maxBytesPerRead="4096"
             maxStringContentLength="200000000"
             maxNameTableCharCount="16384"/>
    </binding>
  </basicHttpBinding>
</bindings>

对于 TCP:

<bindings>
  <netTcpBinding>
    <binding name="tcpBinding"
             maxReceivedMessageSize="20000000"
             maxBufferSize="20000000"
             maxBufferPoolSize="20000000">
      <readerQuotas maxDepth="200"
           maxArrayLength="200000000"
           maxStringContentLength="200000000"
           maxBytesPerRead="4096"
           maxNameTableCharCount="16384"/>
    </binding>
  </netTcpBinding>
</bindings>

IMPORTANT:

如果您尝试传递具有许多连接对象的复杂对象（例如：树数据结构，具有许多对象的列表......），无论您如何增加配额，通信都将失败 . 在这种情况下，您必须增加包含对象的数量：

<behaviors>
  <serviceBehaviors>
    <behavior name="NewBehavior">
      ...
      <dataContractSerializer maxItemsInObjectGraph="2147483646"/>
    </behavior>
  </serviceBehaviors>
</behaviors>
