WCF 问题：远程服务器返回错误：（413）请求实体太大答案

【问题标题】：WCF Issue: The remote server returned an error: (413) Request Entity Too LargeWCF 问题：远程服务器返回错误：（413）请求实体太大

【问题描述】：

我知道这个问题以前被问过很多次，但不幸的是，他们都没有解决我的问题。

我有一个 wcf Web 服务，我可以在其中以字节的形式发送文件。如果文件的大小很大（大约 400 KB），则会出现此错误。对于小型文件，这个问题不会出现。以下是我的服务器端点配置，

<service behaviorConfiguration="CPServicesBehaviour" name="ConsumerPortalAPI.ReceiveNoteService">
  <endpoint address="" binding="customBinding" bindingConfiguration="CustomBinding_IReceiveNoteService" contract="ConsumerPortalAPI.IReceiveNoteService" />
</service>

绑定配置是，

<binding name="CustomBinding_IReceiveNoteService" maxReceivedMessageSize="2147483647" maxBufferSize="2147483647" maxBufferPoolSize="2147483647">
  <security defaultAlgorithmSuite="Default" authenticationMode="SecureConversation" requireDerivedKeys="false" includeTimestamp="false" messageSecurityVersion="WSSecurity11WSTrustFebruary2005WSSecureConversationFebruary2005WSSecurityPolicy11BasicSecurityProfile10"
  canRenewSecurityContextToken="true">
    <secureConversationBootstrap defaultAlgorithmSuite="Default" authenticationMode="UserNameOverTransport" requireDerivedKeys="true" includeTimestamp="true" messageSecurityVersion="WSSecurity11WSTrustFebruary2005WSSecureConversationFebruary2005WSSecurityPolicy11BasicSecurityProfile10">
      <localClientSettings detectReplays="false" />
      <localServiceSettings detectReplays="false" />
    </secureConversationBootstrap>
    <localClientSettings detectReplays="false" />
    <localServiceSettings detectReplays="false" />
  </security>
  <binaryMessageEncoding>
    <readerQuotas maxDepth="32767" maxStringContentLength="2147483647" maxArrayLength="2147483647" maxBytesPerRead="32767" maxNameTableCharCount="2147483647" />
  </binaryMessageEncoding>
  <httpsTransport />
</binding>

默认绑定是，

<binding maxReceivedMessageSize="2147483647" maxBufferSize="2147483647" maxBufferPoolSize="2147483647">
  <security defaultAlgorithmSuite="Default" authenticationMode="SecureConversation" requireDerivedKeys="false" includeTimestamp="false" messageSecurityVersion="WSSecurity11WSTrustFebruary2005WSSecureConversationFebruary2005WSSecurityPolicy11BasicSecurityProfile10"
  canRenewSecurityContextToken="true">
    <secureConversationBootstrap defaultAlgorithmSuite="Default" authenticationMode="UserNameOverTransport" requireDerivedKeys="true" includeTimestamp="true" messageSecurityVersion="WSSecurity11WSTrustFebruary2005WSSecureConversationFebruary2005WSSecurityPolicy11BasicSecurityProfile10">
      <localClientSettings detectReplays="false" />
      <localServiceSettings detectReplays="false" />
    </secureConversationBootstrap>
    <localClientSettings detectReplays="false" />
    <localServiceSettings detectReplays="false" />
  </security>
  <binaryMessageEncoding>
    <readerQuotas maxDepth="32767" maxStringContentLength="2147483647" maxArrayLength="2147483647" maxBytesPerRead="32767" maxNameTableCharCount="2147483647" />
  </binaryMessageEncoding>
  <httpsTransport />
</binding>

在我的测试客户端配置是，

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
  <startup>
    <supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.5" />

          canRenewSecurityContextToken="true">
            <secureConversationBootstrap defaultAlgorithmSuite="Default" authenticationMode="UserNameOverTransport" requireDerivedKeys="true" includeTimestamp="true" messageSecurityVersion="WSSecurity11WSTrustFebruary2005WSSecureConversationFebruary2005WSSecurityPolicy11BasicSecurityProfile10">

            </secureConversationBootstrap>
            <localClientSettings detectReplays="false" />
            <localServiceSettings detectReplays="false" />
          </security>
          <binaryMessageEncoding />

    </client>
  </system.serviceModel>
</configuration>

我尝试将我网站的 uploadReadAheadSize 增加到 10485759。我还尝试将我的网站的 maxAllowedContentLength 增加到 3000000000。

我通过 system.diagnostics 检查了服务器上的 Web 跟踪。以下是跟踪中记录的 Xml 消息，

这似乎可以得到正确的绑定配置，但不知道为什么不使用它。

附：所有绑定都在 customBinding 标签下定义。

在这方面的任何帮助将不胜感激。也许我在这里缺少一些非常小的东西，你们中的任何人都可以指出我正确的方向。

提前致谢。

【问题讨论】：

这是您的客户端踢出的错误还是您的主机返回的错误？你有没有试过把它连接到 Fiddler 看看里面到底发生了什么？您是否尝试过错误记录？
问题来自服务器端。通过跟踪日志，我可以看到我的服务器没有收到该消息。
好吧，您已经为所有配置设置了最大限制。所以，问题不在于限制。不知何故，正在使用默认配置 (65Kb)。我的第一个猜测，请确保您设置完整的合格服务名称，即
也看看forums.asp.net/t/…
感谢 Husnain 的回复。我检查了标记文件和服务名称，似乎是正确的。 ConsumerPortalAPI.ReceiveNoteService 和配置文件一样。

【解决方案1】：

我能够通过在绑定配置中添加以下行来解决此问题。

&lt;httpsTransport maxReceivedMessageSize="2147483647"/&gt;

整个绑定配置现在看起来像，

<binding name="CustomBinding_IReceiveNoteService" maxReceivedMessageSize="2147483647" maxBufferSize="2147483647" maxBufferPoolSize="2147483647">

            <secureConversationBootstrap defaultAlgorithmSuite="Default" authenticationMode="UserNameOverTransport" requireDerivedKeys="true" includeTimestamp="true" messageSecurityVersion="WSSecurity11WSTrustFebruary2005WSSecureConversationFebruary2005WSSecurityPolicy11BasicSecurityProfile10">
