我正在开发一个可以上传和下载图片的网站。下载工作正常，没有问题，但与此同时上传有一个坏的问题，大于16 KB的图片，告诉我：“协议例外：错误400错误请求”。WCF：协议例外 - 400错误请求
这是告诉我，我必须增加XmlDictionaryReaderQuotas中MaxArrayLength的大小，但我已经这样做了。
我会告诉你我的webConfig：
客户：
<bindings>
<basicHttpBinding>
<binding name="BasicHttpBinding_IServiceImage" closeTimeout="00:01:00"
openTimeout="00:01:00" receiveTimeout="00:10:00" sendTimeout="00:01:00"
allowCookies="false" bypassProxyOnLocal="false" hostNameComparisonMode="StrongWildcard"
maxBufferSize="4194304" maxBufferPoolSize="4194304" maxReceivedMessageSize="4194304"
messageEncoding="Text" textEncoding="utf-8" transferMode="Buffered"
useDefaultWebProxy="true">
<readerQuotas maxDepth="4194304" maxStringContentLength="4194304" maxArrayLength="4194304"
maxBytesPerRead="4194304" maxNameTableCharCount="4194304" />
<security mode="None">
<transport clientCredentialType="None" proxyCredentialType="None"
realm="" />
<message clientCredentialType="UserName" algorithmSuite="Default" />
</security>
</binding>
</basicHttpBinding>
</bindings>
WCF：
<bindings>
<basicHttpBinding>
<binding name="BasicHttpBinding_IServiceImage" closeTimeout="00:01:00"
openTimeout="00:01:00" receiveTimeout="00:10:00" sendTimeout="00:01:00"
bypassProxyOnLocal="false" hostNameComparisonMode="StrongWildcard"
maxBufferPoolSize="4194304" maxReceivedMessageSize="4194304"
messageEncoding="Text" textEncoding="utf-8" useDefaultWebProxy="true"
allowCookies="false">
<readerQuotas maxDepth="4194304" maxStringContentLength="4194304" maxArrayLength="4194304"
maxBytesPerRead="4194304" maxNameTableCharCount="4194304" />
<security mode="Message">
<transport clientCredentialType="None" proxyCredentialType="None" realm="" />
</security>
</binding>
</basicHttpBinding>
</bindings>
任何想法？
编辑：我可以上传文件，直到它们小于16KB，并且我无法找到必须处理该值才能增加的位置。
听起来像是巨大的文件，WCF已经得到了一些问题，所以我要改变“encodeMessage”以MTOM和BasicHttpBindings移到wsHttpBindings。顺便说一下，这还没有工作，新的问题出现在我的代码。该死的。
客户WebConfig：
<bindings>
<wsHttpBinding>
<binding name="wsHttpBinding_IService1" closeTimeout="00:01:00"
openTimeout="00:01:00" receiveTimeout="00:10:00" sendTimeout="00:01:00"
bypassProxyOnLocal="false" hostNameComparisonMode="StrongWildcard"
maxBufferPoolSize="4194304" maxReceivedMessageSize="4194304"
messageEncoding="Mtom" textEncoding="utf-8" useDefaultWebProxy="true"
allowCookies="false">
<readerQuotas maxDepth="4194304" maxStringContentLength="4194304"
maxArrayLength="4194304" maxBytesPerRead="4194304" maxNameTableCharCount="4194304" />
<security mode="None">
<transport clientCredentialType="None" proxyCredentialType="None"
realm="" />
<message clientCredentialType="UserName" algorithmSuite="Default" />
</security>
</binding>
</wsHttpBinding>
</bindings>
服务WebConfig：
<bindings>
<wsHttpBinding>
<binding name="wsHttpBinding_IService1" closeTimeout="00:01:00"
openTimeout="00:01:00" receiveTimeout="00:10:00" sendTimeout="00:01:00"
allowCookies="false" bypassProxyOnLocal="false" hostNameComparisonMode="StrongWildcard"
maxBufferPoolSize="4194304" maxReceivedMessageSize="4194304"
messageEncoding="Mtom" textEncoding="utf-8" useDefaultWebProxy="true">
<!--messageEncoding="Text" textEncoding="utf-8" maxBufferSize="4194304" transferMode="Buffered" -->
<readerQuotas maxDepth="4194304" maxStringContentLength="4194304"
maxArrayLength="4194304" maxBytesPerRead="4194304" maxNameTableCharCount="4194304" />
<security mode="None">
<transport clientCredentialType="None" proxyCredentialType="None"

<message clientCredentialType="UserName" algorithmSuite="Default" />
</security>
</binding>
</wsHttpBinding>
</bindings>
<services>
<service name="WcfService.FileService" >
<endpoint address="" binding="wsHttpBinding" contract="WcfService.IService1" />
</service>
</services>
您的配置是否用于服务端点？ –
@LadislavMrnka：我认为这是你在问： <端点地址= “HTTP：//本地主机：XXXXX/Service1.svc” 绑定= “basicHttpBinding的” bindingConfiguration = “BasicHttpBinding_IServiceImage” 合同=“WCFImages .IServiceImage“ name =”BasicHttpBinding_IServiceImage“/> 就像我说的，对于小图像，工作正常。大于2KB不是。 –
