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

</endpoint>
</client>
<behaviors>

<bindings> <basicHttpBinding>
<binding name="PermissionServiceSoap" />
<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。

if (!string.IsNullOrWhiteSpace(itemName) && !string.IsNullOrWhiteSpace(itemName))
{
using (DataTable dt = ItemsManager.GetItemsDB(userInfo, "ItemsClass"))
{
//过滤 显示或不显示 DeletionStateCode为0的字段显示，Enabled为1的字段
BaseBusinessLogic.SetFilter(dt, BaseItemDetailsEntity.FieldDeletionStateCode, "0");
BaseBusinessLogic.SetFilter(dt, BaseItemDetailsEntity.FieldEnabled, "1");
DataTable dtNew = new DataTable();
dtNew.Columns.Add("key", typeof(string));
dtNew.Columns.Add("value", typeof(string));
for (int i = 0; i < dt.Rows.Count; i++)
{
DataRow row = dtNew.NewRow();
row["key"] = dt.Rows[i]["ITEMNAME"];
row["value"] = dt.Rows[i]["ITEMVALUE"];
dtNew.Rows.Add(row);
}
jsonStr = DataTableHelper.DataTable2Json(dtNew);
}
}
else
{
jsonStr = "{\"list\":[{\"key\":\"出错了\",\"value\":\"取数据出错\",\"myFlag\":\"没有传入参数值\"}]}";
}
Response.Write(jsonStr);
Response.End();

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。
