尝试上传大文件时获取异常

Question

我正在使用wshttpbinding来提供服务

<wsHttpBinding>
            <binding name="wsHttpBinding_Windows" maxBufferPoolSize="9223372036854775807" maxReceivedMessageSize="2147483647">
                <readerQuotas maxArrayLength="2147483647" maxBytesPerRead="2147483647" maxStringContentLength="2147483647" maxNameTableCharCount="2147483647"/>
                <security mode="Message">
                    <message clientCredentialType="Windows"/>
                </security>
            </binding>
        </wsHttpBinding>

<behavior name="ServiceBehavior">
                <dataContractSerializer  maxItemsInObjectGraph="6553600"/>
                <serviceThrottling maxConcurrentCalls="2147483647" maxConcurrentInstances="2147483647" maxConcurrentSessions="2147483647"/>
            </behavior>

当我尝试上传15Mb的文件时,它会抛出下面的EndPointNotFoundException:

例外消息:

There was no endpoint listening at "MY SERVICE URL" that could accept the message. This is often caused by an incorrect address or SOAP action. See InnerException, if present, for more details.

例外:

The remote server returned an error: (404) Not Found.

有(2)个设置maxRequestLength,maxAllowedContentLength在WCF配置的服务器端,您需要增加以便解决此异常.在WCF服务服务器端的.config中,请确保添加以下内容:

<system.web>
  <!--Increase 'maxRequestLength' to needed value: 100mb (value is in kilobytes)-->
  <httpRuntime maxRequestLength="102400"/>
</system.web>

<system.webServer>
  <security>
    <requestFiltering>
      <!--Increase 'maxAllowedContentLength' to needed value: 100mb (value is in bytes)-->
      <requestLimits maxAllowedContentLength="104857600" />
    </requestFiltering>
  </security>
</system.webServer>
