wcf - WCF 服务错误 400 错误请求

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，但是我尝试过的一切都不起作用，问题是我正在使用托管在 IIS 上的 WCF 服务，以及一个尝试在字符串上上传序列化图像，图像大小约为 9mb，其他一切正常，我可以毫无问题地发送数据，除了图像。

我启用了跟踪日志并且错误消息说 MaxReceivedMessageSize 超过

这是我的服务配置：

<system.diagnostics>
<sources>
    <source name="System.ServiceModel"
        switchValue="Information, ActivityTracing"
        propagateActivity="true" >

和客户端配置

<system.serviceModel>
    <bindings>
        <basicHttpBinding> 
            <binding name="BasicHttpBinding_IServicioSalud" closeTimeout="10:01:00"
                openTimeout="10:01:00" receiveTimeout="10:10:00" sendTimeout="10:01:00"

                maxBufferSize="2147483647" maxBufferPoolSize="2147483647" maxReceivedMessageSize="2147483647"
                messageEncoding="Text" textEncoding="utf-8" transferMode="Buffered"

                    <message clientCredentialType="UserName" algorithmSuite="Default" />
                </security>
            </binding>
        </basicHttpBinding>
    </bindings>
    <client>
        <endpoint address="http://xxx.xxx.x.xxx:xxxx/wcfservicesalud/Service.svc"
            binding="basicHttpBinding" bindingConfiguration="BasicHttpBinding_IServicioSalud"
            contract="IServicioSalud" name="BasicHttpBinding_IServicioSalud" />
    </client>
</system.serviceModel>

Answer 1

在您的配置文件中，您尚未分配您创建的绑定配置，因此使用默认值BasicHttpBinding。您需要将您定义的绑定 (BasicHttpBinding_IServicioSalud) 显式分配给您的端点，如下所示：

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

为您的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。就我而言，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，原因是在我的请求中我没有设置内容类型。
