我遇到了这个显然很常见的问题,但一直无法解决。
如果我使用数组参数中相对较少的条目调用 WCF Web 服务(我已经测试了50个) ,那么一切都很好。
然而,如果我调用带有500个条目的 Web 服务,就会得到 Bad Request 错误。
有趣的是,我在服务器上运行了 金线鲨,发现请求甚至没有到达服务器——400错误是在客户端生成的。
唯一的例外是:
系统。服务模式。ProtocolException: 远程服务器返回一个意外响应: (400)错误请求。—— > 制度。网。WebException: 远程服务器返回一个错误: (400) Bad Request。
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"

</wsHttpBinding>

<client>

binding="wsHttpBinding" bindingConfiguration="WSHttpBinding_IMyService"
contract="SmsSendingService.IMyService" name="WSHttpBinding_IMyService" />
</client>
</system.serviceModel>
在服务器端,web.config 文件包含以下 system.serviceModel
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>
有人能帮我吗?
