当所有超时参数设置为最大值时,WCF服务超时

我有一个WCF服务,它有一个非常耗时的方法,可以将大数据文件上传到“azure table 存储”。

我在运行时在客户端设置我的超时,如下所示: -

binding = new BasicHttpBinding();
binding.CloseTimeout = TimeSpan.FromMilliseconds(2147483647.0);
binding.OpenTimeout = TimeSpan.FromMilliseconds(2147483647.0);
binding.ReceiveTimeout = TimeSpan.FromMilliseconds(2147483647.0);
binding.SendTimeout = TimeSpan.FromMilliseconds(2147483647.0);

我的web.config的超时设置如下: -

<bindings>
      <basicHttpBinding>
        <binding maxBufferPoolSize="2147483647" maxReceivedMessageSize="2147483647" sendTimeout="22:30:00" receiveTimeout="22:30:00" openTimeout="22:30:00" closeTimeout="22:30:00" maxBufferSize="2147483647">
          <readerQuotas maxArrayLength="2147483647" maxBytesPerRead="2147483647" maxDepth="2147483647" maxNameTableCharCount="2147483647" maxStringContentLength="2147483647" />
        </binding>
      </basicHttpBinding>
    </bindings>

我在VS 2012中运行我的代码,我看到的问题是文件上传方法在60分钟后因未处理的CommunicationException而崩溃:远程服务器返回错误:NotFound。如果我按F5,则上传继续并完成。此时崩溃出现在Reference.cs文件中: -

public void EndFileUploadMethod(System.IAsyncResult result) {
                object[] _args = new object[0];
                base.EndInvoke("FileUploadMethod", _args, result);

对于文件上传,还有一些其他配置需要到位。首先,您要上传的文件有多大?如果他们是>大约50MB左右,你可能需要将它们分成小块并将它们发送出去。

在此之前,请尝试将以下设置添加到您的配置中。不要担心<authentication><compilation>标记。这是感兴趣的<httpRuntime><requestLimits>标记。

我的maxAllowedContentLength属性值在下面是任意的,因此您可以将其设置为您想要的任何值。我相信它是以字节为单位的。

  <system.web>
    <compilation debug="true" targetFramework="4.0"/>
    <authentication mode="Windows" />
    <httpRuntime maxRequestLength="2147483647" />
  </system.web>

  <system.webServer>
    <security>
      <requestFiltering>
        <requestLimits maxAllowedContentLength="2000000000" />
      </requestFiltering>
    </security>
  </system.webServer>

我使用类似的azure blob来存储我的内容。我的代码没有任何设置。试试看,让我知道。

    public static CloudBlobContainer Container
    {
        get
        {
            CloudStorageAccount.SetConfigurationSettingPublisher((configName, configSetter) =>
                {
                    // Provide the configSetter with the initial value
                    configSetter(RoleEnvironment.GetConfigurationSettingValue(configName));
                    RoleEnvironment.Changed += (sender, arg) =>
                    {
                        if (arg.Changes.OfType<RoleEnvironmentConfigurationSettingChange>().Any((change) =>
                        (change.ConfigurationSettingName == configName)))
                        {
                            // The corresponding configuration setting has changed, so propagate the value
                            if (!configSetter(RoleEnvironment.GetConfigurationSettingValue(configName)))
                            {
                                // In this case, the change to the storage account credentials in the
                                // service configuration is significant enough that the role needs to be
                                // recycled in order to use the latest settings (for example, the 
                                // endpoint may have changed)
                                RoleEnvironment.RequestRecycle();
                            }
                        }
                    };
                });
            CloudStorageAccount acc = CloudStorageAccount.FromConfigurationSetting("RecordingsStorageAccount");
            CloudBlobClient bc = acc.CreateCloudBlobClient();
            CloudBlobContainer c = bc.GetContainerReference(RoleEnvironment.GetConfigurationSettingValue("RecordingsContainer"));
            return c;
        }
    }
