我遇到了这个明显常见的问题,并且一直无法解决它。

如果我在数组参数中使用相对较少的项目来调用web服务(我已经测试了多达50个),那么一切都很好。

但是,如果我调用包含500个项目的web服务,则会收到错误的请求错误。

有趣的是,我在服务器上运行了Wireshark,看起来请求甚至没有命中服务器-- 400错误是在客户端生成的。

例外是:

System.ServiceModel.ProtocolException:远程服务器返回意外响应:(400)错误请求。-> System.Net.WebException:远程服务器返回错误:(400)错误请求。

我的客户端配置文件的system.serviceModel 部分是:

 <system.serviceModel>
    <bindings>
        <wsHttpBinding>
            <binding name="WSHttpBinding_IMyService" closeTimeout="00:01:00"
                openTimeout="00:01:00" receiveTimeout="00:10:00" sendTimeout="00:01:00"
                bypassProxyOnLocal="false" transactionFlow="false" hostNameComparisonMode="StrongWildcard"
                maxBufferPoolSize="524288" maxReceivedMessageSize="2147483647"
                messageEncoding="Text" textEncoding="utf-8" useDefaultWebProxy="true"
                allowCookies="false">
                <readerQuotas maxDepth="32" maxStringContentLength="8192" maxArrayLength="2147483647"
                    maxBytesPerRead="4096" maxNameTableCharCount="16384" />
                <reliableSession ordered="true" inactivityTimeout="00:10:00"
                    enabled="false" />
                <security mode="None">
                    <transport clientCredentialType="Windows" proxyCredentialType="None"
                        realm="" />
                    <message clientCredentialType="Windows" negotiateServiceCredential="true"
                        establishSecurityContext="true" />
                </security>
            </binding>
        </wsHttpBinding>
    </bindings>
    <client>
        <endpoint address="http://serviceserver/MyService.svc"
            binding="wsHttpBinding" bindingConfiguration="WSHttpBinding_IMyService"
            contract="SmsSendingService.IMyService" name="WSHttpBinding_IMyService" />
    </client>
</system.serviceModel>

在服务器端,我的web.config文件包含以下部分:

<system.serviceModel>
    <services>
        <service name="MyService.MyService" behaviorConfiguration="MyService.MyServiceBehaviour" >
            <endpoint address="" binding="wsHttpBinding" bindingConfiguration="MyService.MyServiceBinding" contract="MyService.IMyService">
            </endpoint>
            <endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange"/>
        </service>
    </services>
    <bindings>
      <wsHttpBinding>
        <binding name="MyService.MyServiceBinding">
          <security mode="None"></security>
        </binding>
      </wsHttpBinding>
    </bindings>
    <behaviors>
        <serviceBehaviors>
            <behavior name="MyService.MyServiceBehaviour">
                <!-- 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>
</system.serviceModel>

I‘’ve looked at a fairly large number of answers to this question with no success.

有人能帮我吗?
