c# - 调用 WCF 服务传递字节数组的错误请求

Question

我是 StackOverflow 的新手，所以如果我弄错了请原谅我。调用 wcf 服务时出现错误请求错误。该方法将字节数组作为参数。它适用于小文件，但不适用于长度为 80000 字节的文件。我已经在下面发布了网络配置文件。

这是在我的网络配置文件中

    <system.serviceModel>
<bindings>
  <basicHttpBinding>
    <binding name="BasicHttpBinding_IFileService" closeTimeout="00:01:00"
      openTimeout="00:01:00" receiveTimeout="00:10:00" sendTimeout="00:01:00"
      allowCookies="false" bypassProxyOnLocal="false" hostNameComparisonMode="StrongWildcard"
      maxBufferSize="2147483647" maxBufferPoolSize="2147483647" maxReceivedMessageSize="2147483647"
      messageEncoding="Text" textEncoding="utf-8" transferMode="Buffered"
      useDefaultWebProxy="true">
      <readerQuotas maxDepth="2147483647" maxStringContentLength="2147483647" maxArrayLength="2147483647"
        maxBytesPerRead="2147483647" maxNameTableCharCount="2147483647" />
      <security mode="None">
        <transport clientCredentialType="None" proxyCredentialType="None"
          realm="" />
        <message clientCredentialType="UserName" algorithmSuite="Default" />
      </security>
    </binding>
  </basicHttpBinding>
</bindings>
<client>
  <endpoint address="http://localhost:4199/FileService.svc" binding="basicHttpBinding"
    bindingConfiguration="BasicHttpBinding_IFileService" contract="ConStringServices.IFileService"
    name="BasicHttpBinding_IFileService" />
</client>

这是在我的服务网络配置文件中

    <system.serviceModel>
    <bindings>
        <basicHttpBinding>
            <binding name="basicBinding" maxReceivedMessageSize="2147483647">
                <readerQuotas maxArrayLength="2147483647" maxBytesPerRead="2147483647" maxDepth="2147483647" maxNameTableCharCount="2147483647" maxStringContentLength="2147483647"/>
            </binding>              
        </basicHttpBinding>         
    </bindings>
    <services>
        <service behaviorConfiguration="MyServiceBehavior" name="MyService">
            <endpoint  bindingConfiguration="basicBinding" address="" binding="basicHttpBinding" contract="ConStringTest.Services.IFileService">
                <identity>
                    <dns value="localhost" />
                </identity>
            </endpoint>             
        </service>          
    </services>
    <behaviors>
        <serviceBehaviors>
            <behavior name="MyServiceBehavior">
                <!-- To avoid disclosing metadata information, set the value below to false and remove the metadata endpoint above before deployment -->
                <serviceMetadata httpGetEnabled="true"/>
                <!-- To receive exception details in faults for debugging purposes, set the value below to true.  Set to false before deployment to avoid disclosing exception information -->
                <serviceDebug includeExceptionDetailInFaults="true"/>
            </behavior>
        </serviceBehaviors>
    </behaviors>
    <serviceHostingEnvironment multipleSiteBindingsEnabled="true" />
</system.serviceModel>

更新:这是在服务中调用的方法。正如我所说，它适用于小文件。

    public Boolean UploadFile(Byte[] file, string filename)
    {
        FileStream stream = new FileStream("C:\\Temp\\" + filename, FileMode.Create, FileAccess.ReadWrite);
        stream.Write(file, 0, file.Length);
        stream.Close();

        Console.WriteLine(file.Length);
        return true;
    }

我做错了什么？任何帮助将不胜感激。 更新:我已经像上面那样修改了服务配置文件，但仍然没有任何乐趣。 更新:已修复。我只需要将服务名称设为带命名空间的完全限定名称。 IE。 ConStringTest.Services.FileService

问题在于您放置名称的配置。这不是任意名称，而是服务类文件的名称。如果错误，则不会应用该配置并将使用默认配置。将 MyService 更改为服务类的完全限定名称..

<service behaviorConfiguration="MyServiceBehavior" name="ConStringTest.Services.FileService">
    <endpoint  bindingConfiguration="basicBinding" address="" binding="basicHttpBinding" contract="ConStringTest.Services.IFileService">
        <identity>
            <dns value="localhost" />
        </identity>
    </endpoint>             
</service>
