c# - maxReceivedMessageSize 未解决 WCF 错误 413 请求实体太大问题

Question

我在 WCF 4.0 上遇到 413 Request Entity Too Large 错误。

这是服务器 web.config 文件：

      </serviceActivations>
    </serviceHostingEnvironment>
  </system.serviceModel>

这是客户端 web.config 文件：

<system.serviceModel>
    <behaviors>
      <endpointBehaviors>
        <behavior name="WCFAuthenticationBehavior">
          <clientCredentials>
            <clientCertificate storeLocation="CurrentUser" x509FindType="FindBySubjectName" findValue="ClientWCFAuthentification" />
          </clientCredentials>
        </behavior>
      </endpointBehaviors>
    </behaviors>
    <bindings>
      <wsHttpBinding>
        <binding name="customWsHttpBinding" maxBufferPoolSize="2147483647"
                 maxReceivedMessageSize="2147483647">
          <security mode="Transport">
            <transport clientCredentialType="Certificate" />
          </security>
          <readerQuotas maxDepth="2147483647" maxStringContentLength="2147483647"
                        maxArrayLength="2147483647" maxBytesPerRead="2147483647"
                        maxNameTableCharCount="2147483647"/>
        </binding>
      </wsHttpBinding>
    </bindings>
    <client>
      <endpoint address="https://wcfauthentication.local/ServiceWCFAuthentication.svc/" 
                behaviorConfiguration="WCFAuthenticationBehavior"
          binding="wsHttpBinding" bindingConfiguration="customWsHttpBinding"
          contract="WCFAuthentification.IWCFAuthentication" name="MyEndPoint" />
    </client>
  </system.serviceModel>

当我启动这部分代码时：

String strEndPointAddress = "https://wcfauthentication.local/ServiceWCFAuthentication.svc";
var remoteAddress = new EndpointAddress(strEndPointAddress);
_wcf = new WCFAuthenticationClient("MyEndPoint", "https://wcfauthentication.local/ServiceWCFAuthentication.svc");

//result = _wcf.MyMethod("1", "test", LargeString.Substring(0,100), "Data1");
result = _wcf.MyMethod("1", "test", LargeString, "Data1");

我得到了错误。但是，当我在该部分添加注释行并使用较小的字符串执行 MyMethod 方法时，使用大字符串的第二种方法有效，WCF 可以处理它。

您知道为什么当我在具有大数据的方法之前添加另一种方法时，413 Error Request Entity Too Large 会消失吗？

是否有必要使用诸如“CallMeBeforeAnyOtherCall()”之类的虚拟方法来启动 WCF 连接？
