c# - WCF 超时异常! mscorlib.dll 中出现类型为 'System.TimeoutException' 的异常

Question

我在 asp.net web 应用程序中使用 wcf 服务，wcf 服务中的函数有时需要超过 1 分钟才能响应，在这种情况下会引发异常。我不确定如何增加此请求超时，我尝试了 wcf 配置文件但不起作用我是否也必须在我的 Web 应用程序端执行此操作？如果是这样，如何？请帮忙!

异常详情: 附加信息:请求 channel 在 00:00:59.8689077 之后等待回复时超时。增加传递给 Request 调用的超时值或增加 Binding 上的 SendTimeout 值。分配给此操作的时间可能是较长超时的一部分。

也尝试在您的 asp.net 网络配置中设置超时

这是来 self 的一位消费者的示例，它使用流式数据，因此超时至关重要

<system.serviceModel>
  <bindings>
        <basicHttpBinding>
            <binding name="BasicHttpBinding_IStreamed" transferMode="Streamed" messageEncoding="Mtom"  maxReceivedMessageSize="67108864" maxBufferSize="65536"
              closeTimeout="00:01:00" openTimeout="00:01:00"
              receiveTimeout="00:10:00" sendTimeout="00:01:00"/>
        </basicHttpBinding>
    </bindings>
    <client>
        <endpoint address="http://localhost:#####/streamed.svc" binding="basicHttpBinding"
            bindingConfiguration="BasicHttpBinding_IStreamed"
            contract="SyncSVC.IStreamed" name="BasicHttpBinding_IStreamed" />
    </client>
</system.serviceModel>
