Question

我一直在搜索这个问题，我发现其他用户发布了类似的问题，但我尝试的一切都不起作用，问题是我使用的是IIS上托管的WCF服务和客户端试图在字符串上上传一个序列化的图像，图像的大小是9mb aprox，其他一切正常，我可以发送没有问题的数据，除了图像。

我启用了tracelog，错误消息显示MaxReceivedMessageSize超过

这是我的服务配置：

        switchValue="Information, ActivityTracing"

Answer 1

在配置文件中，您尚未分配您创建的绑定配置，因此正在使用BasicHttpBinding的默认值。您需要明确地将您定义的绑定（BasicHttpBinding_IServicioSalud）分配给您的端点，如下所示：

<endpoint address="" bindingConfiguration="BasicHttpBinding_IServicioSalud" binding="basicHttpBinding" contract="IServicioSalud" />

为服务配置执行此操作，因为需要将服务设置为接受更大的数据。

Answer 2

这是我的版本。确保您在所需的服务中指定了 bindingConfiguration 。在我的情况下，我必须指定名称 basicHttpBinding 。

<bindings>
   <basicHttpBinding>
    <binding name="basicHttpBinding" maxBufferSize="64000000" maxReceivedMessageSize="64000000" maxBufferPoolSize="64000000">
      <readerQuotas maxDepth="64000000" maxStringContentLength="64000000" maxArrayLength="64000000" maxBytesPerRead="64000000" />
      <security mode="None"/>
    </binding>
    </basicHttpBinding>
</bindings>


<services>
      <service behaviorConfiguration="WS.Service1Behavior" name="WS.EasyStockWS">
        <endpoint address="" binding="basicHttpBinding" bindingConfiguration="basicHttpBinding" contract="WS.IEasyStockWS">
          <identity>
            <dns value="localhost" />
          </identity>
        </endpoint>
        <endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange" />
      </service>
</services>

Answer 3

对我来说，原因是我的请求中没有设置内容类型。
