以WCF安全认证方式调用通用权限管理系统获取基础信息资料

在B/S开发中，涉及到获取系统基础资料的问题，因为是在不同平台下的开发，采用了WCF方式获取。

下面是一个调用通用权限管理系统（吉日嘎拉）基础信息资料的一个demo供参考

调用原理图：

web.configWCF配置参考

web.config 相关配置

  <system.serviceModel>
    <client>
      <endpoint address="http://192.168.1.199/PermissionService.asmx"
          binding="basicHttpBinding" bindingConfiguration="PermissionServiceSoap"
          contract="WebPermission.PermissionServiceSoap" name="PermissionServiceSoap">

        <identity>
          <dns value="192.168.1.199" />
        </identity>
      </endpoint>
      <endpoint address="net.tcp://192.168.1.199:9999/DotNet.Business/BaseItemsService/" behaviorConfiguration="Internet" binding="netTcpBinding" bindingConfiguration="netTcpBindingSmiple" contract="DotNet.Business.IBaseItemsService" name="DotNet.Business.BaseItemsService">

    </client>

        <binding name="basicHttpBindingSmiple"  maxBufferPoolSize="2147483647" maxBufferSize="2147483647" maxReceivedMessageSize="2147483647">
          <security mode="None">
            <transport clientCredentialType="Windows" />
          </security>
        </binding>
      </basicHttpBinding>
      
      <netTcpBinding>
        <binding name="netTcpBindingSmiple" maxBufferSize="2147483647" maxBufferPoolSize="2147483647" maxReceivedMessageSize="2147483647">
          <security mode="None">
            <transport clientCredentialType="Windows" />
            <message clientCredentialType="Windows" />
          </security>
        </binding>
      </netTcpBinding>
      
    </bindings>

  </system.serviceModel>

注意：下面的userInfo是登录通用权限管理系统后的用户信息表，登录后需要设置对应的安全认证信息。

这段时间一直在基于吉日嘎拉的通用权限管理系统上做开发，真心感觉他真的是很强大，

他真的不仅仅是一套权限管理系统，底层涉及到的安全问题考虑的也非常全面。

用上这套权限管理系统，我们只需关心业务就行了，时间对开发人员、对公司来说都非常重要，有一个好的选择我们一定要用上。

今后有机会会分享更多的应用，欢迎使用过这套系统的朋友一起交流。
