WCF - 大文件上传 - （413）请求实体太大

有人可以看看我的新代码吗？我卡在这个bug 3天现在和它的驾驶我疯狂......WCF - 大文件上传 - （413）请求实体太大

我想有一个WCF文件上传，但大文件没有上传

我得到这个错误：“远程服务器返回了意外的响应：（413）请求实体太大。”

我的项目是由3个部分组成内置：

WCF服务
使用该服务使用用户控制
网站的用户控件

这是我的服务we.config：

<system.serviceModel> 

    <services> 
     <service name="AttachmentService" behaviorConfiguration=""> 
     <endpoint name="DefaultEndPoint" address="http://localhost:54893/AttachmentService.svc" 
        behaviorConfiguration="EndpointBehaviors" 
        binding="wsHttpBinding" bindingName="AttachmentBinding" 
        contract="AttachmentsService.IAttachmentService"></endpoint> 
     </service> 
    </services> 

    <behaviors> 
     <serviceBehaviors> 
     <behavior name=""> 
      <serviceMetadata httpGetEnabled="true" httpsGetEnabled="true" /> 
      <serviceDebug includeExceptionDetailInFaults="true"/> 
      <dataContractSerializer maxItemsInObjectGraph="2147483647" /> 
     </behavior> 
     </serviceBehaviors> 

     <endpointBehaviors> 
     <behavior name="EndpointBehaviors"> 
      <dataContractSerializer maxItemsInObjectGraph="2147483647" /> 
     </behavior> 
     </endpointBehaviors> 
    </behaviors> 

    <bindings> 
     <basicHttpBinding> 
     <binding name="AttachmentBinding" maxReceivedMessageSize="2147483647" maxBufferSize="2147483647" maxBufferPoolSize="2147483647" receiveTimeout="00:01:00" sendTimeout="00:01:00" 
       textEncoding="utf-8" openTimeout="00:01:00"> 
      <readerQuotas maxDepth="2147483647" maxStringContentLength="2147483647" maxArrayLength="2147483647" maxBytesPerRead="2147483647" maxNameTableCharCount="2147483647"/> 
      <security mode="None" /> 
     </binding> 
     </basicHttpBinding> 
    </bindings> 
    <serviceHostingEnvironment multipleSiteBindingsEnabled="true" aspNetCompatibilityEnabled="true" /> 
    </system.serviceModel>

这里是我的用户控制的app.config：

<?xml version="1.0" encoding="utf-8" ?> 
<configuration> 
    <system.serviceModel> 
    <bindings> 
     <basicHttpBinding> 
     <binding name="BasicHttpBinding_IAttachmentService" maxBufferSize="2147483647" maxBufferPoolSize="524288" maxReceivedMessageSize="2147483647"> 
      <readerQuotas maxDepth="128" maxStringContentLength="2147483647" maxArrayLength="16384" maxBytesPerRead="4096" maxNameTableCharCount="16384" /> 
     </binding> 
     </basicHttpBinding> 
    </bindings> 
    <client> 
     <endpoint address="http://localhost:54893/AttachmentService.svc" 
      binding="basicHttpBinding" bindingConfiguration="BasicHttpBinding_IAttachmentService" 
      contract="AttachmentsService.IAttachmentService" name="BasicHttpBinding_IAttachmentService" /> 
    </client> 
    </system.serviceModel> 
</configuration>

这里是我的UI的web.config：

<system.webServer> 
    <security> 
     <requestFiltering> 
     <requestLimits maxAllowedContentLength="2147483647" /> 
     </requestFiltering> 
    </security> 
    <serverRuntime enabled="true" uploadReadAheadSize="2147483647" maxRequestEntityAllowed="2147483647" /> 
    </system.webServer> 

    <system.serviceModel> 
    <bindings> 
     <basicHttpBinding> 
     <binding name="BasicHttpBinding_IAttachmentService" maxBufferSize="2147483647" maxBufferPoolSize="524288" maxReceivedMessageSize="2147483647"> 
      <readerQuotas maxDepth="128" maxStringContentLength="2147483647" maxArrayLength="16384" maxBytesPerRead="4096" maxNameTableCharCount="16384" /> 
     </binding> 
     </basicHttpBinding> 
    </bindings> 
    <client> 
     <endpoint address="http://localhost:54893/AttachmentService.svc" 
      binding="basicHttpBinding" bindingConfiguration="BasicHttpBinding_IAttachmentService" 
      contract="AttachmentsService.IAttachmentService" name="BasicHttpBinding_IAttachmentService" /> 
    </client> 
    </system.serviceModel>

这里是我是如何实现的引用调用：

public void UploadFile(string serviceUrl,decimal maxFileSize, AttachmentFileParams fileParams, Stream file) 
{ 
    AttachmentServiceClient client = null; 
    try 
    { 
     if (file.Length > (maxFileSize * 1024)) //maxFileSize is defined in KB and file.Length is in Bytes 
        return Serialization.ConvertToJson(new { IsError = true, ErrorMessage = Constants.Messages.MaxFileSizeExceeded + maxFileSize }); 

       string requestUrl = string.Format("{0}/UploadFile", serviceUrl); 
       string jsonFile = Serialization.ConvertToJson(fileParams); 
       byte[] jsonFileBytes = Encoding.UTF8.GetBytes(jsonFile); 
       byte[] len = BitConverter.GetBytes(jsonFileBytes.Length); 

       using (client = new AttachmentServiceClient()) 
       { 
        client.UploadFile(file); 
       } 
    } 
    catch (Exception ex) 
    { } 
    finally 
    { 
     try 
       { 
        if (client.State != System.ServiceModel.CommunicationState.Closed) 
         client.Close(); 
       } 
       catch 
       { 
        client.Abort(); 
       } 
    } 
}

有什么我失踪了吗？

可能这会帮助你。 http://stackoverflow.com/a/24932150/1660178 –

你需要在你的绑定中使用'transfermode'我想。关注https://msdn.microsoft.com/en-us/library/ms789010(v=vs。 110）.aspx –

好了，我终于解决了它，这里是为我工作我的配置文件：

WCF服务的web.config文件：

<?xml version="1.0"?> 
<configuration> 
    <system.web> 
    <compilation debug="true" targetFramework="4.0" /> 
    <httpRuntime maxRequestLength="2147483647" /> 
    </system.web> 

    <system.serviceModel> 
    <serviceHostingEnvironment aspNetCompatibilityEnabled="true"/> 
    <services> 
     <!-- The name of the service --> 
     <service name="WcfService1.Service1"> 
     <!--you can leave the address blank or specify your end point URI--> 
     <endpoint binding="webHttpBinding" bindingConfiguration="higherMessageSize" contract="WcfService1.IService1" behaviorConfiguration="Web" /> 
     </service> 
    </services> 
    <bindings> 
     <webHttpBinding> 
     <!-- configure the maxReceivedMessageSize value to suit the max size of the request (in bytes) you want the service to receive--> 
     <binding name="higherMessageSize" transferMode="Streamed" maxReceivedMessageSize="2147483647" /> 
     </webHttpBinding> 
    </bindings> 

    <behaviors> 
     <serviceBehaviors> 
     <behavior> 
      <serviceMetadata httpGetEnabled="true"/> 
      <serviceDebug includeExceptionDetailInFaults="false"/> 
     </behavior> 
     </serviceBehaviors> 
     <endpointBehaviors> 
     <behavior name="Web"> 
      <webHttp/> 
     </behavior> 
     </endpointBehaviors> 
    </behaviors> 
    <!--<serviceHostingEnvironment multipleSiteBindingsEnabled="false" />--> 
    </system.serviceModel> 

    <system.webServer> 
    <modules runAllManagedModulesForAllRequests="true"/> 
    </system.webServer> 
</configuration>

客户端app.config/web.config文件：

<?xml version="1.0" encoding="utf-8"?> 
<configuration> 
    <system.web> 
    <compilation debug="true" targetFramework="4.0" /> 
    <httpRuntime maxRequestLength="2147483647" /> 
    </system.web> 

    <system.serviceModel> 
    <bindings> 
     <webHttpBinding> 
     <binding name="BasicHttpBinding_IService1" maxReceivedMessageSize="2147483647" /> 
     </webHttpBinding> 
    </bindings> 
    <client> 
     <endpoint address="http://localhost:59540/Service1.svc" behaviorConfiguration="webhttp" 
     binding="webHttpBinding" bindingConfiguration="BasicHttpBinding_IService1" 
     contract="ServiceReference1.IService1" name="BasicHttpBinding_IService1" /> 
    </client> 
    <behaviors> 
     <endpointBehaviors> 
     <behavior name="webhttp"> 
      <webHttp/> 
     </behavior> 
     </endpointBehaviors> 
    </behaviors> 
    </system.serviceModel> 
</configuration>

我希望这会节省我花费的时间来解决它:-)

我在使用IIS服务器上传大文件时遇到同样的问题。

我发现有您需要修改web.config

<system.web> 
    <httpRuntime maxRequestLength="50000"/> 
</system.web>

和

<system.webServer> 
    <security> 
    <requestFiltering> 
     <requestLimits maxAllowedContentLength="50000000" /> <!-- Allow files of upto 50,000,000 bytes (about 50Mb) to be uploaded --> 
    </requestFiltering> 
    </security> 
</system.webServer>

希望这有助于两个地方。

我已经在我的web.config中有这些设置 –
