题
在我们公司中,我们有存储在SharePoint中的机密信息。一些政治有效的人员正在推动发送到外部电子邮件地址的警报。如何将内容发送到内部电子邮件和警报的自定义电子邮件警报,而不包含外部电子邮件地址?
解决方案
创建新的警报模板
1创建一个框模板的副本,更改名称,ID,并将调用添加到自定义处理程序到每个。
-
使自定义模板在其名称结束时具有“.ext”。
-
自定义功能也调用自定义NotificationshanderAssembly
using System; using System.Runtime.InteropServices; using Microsoft.SharePoint; using Microsoft.SharePoint.Administration; using System.Xml; namespace Prov.Shared.CCPersonalEmail.Features.AlertTemplates { public class AlertTemplatesEventReceiver : SPFeatureReceiver { public override void FeatureActivated(SPFeatureReceiverProperties properties) { //The Properties we will add to the Alert Template //(Since this feature lives in the same project with the //IAlertNotifyHandler we just refer to our own assembly) string ClassToAdd = "CCPersonalClass"; SPFeatureDefinition FeatDef = (SPFeatureDefinition)properties.Feature.Definition; string ourAssemblyName = FeatDef.ReceiverAssembly; SPWebApplication WebApplication = (SPWebApplication)properties.Feature.Parent; SPWebService WebService = WebApplication.WebService; SPAlertTemplateCollection colSPAT = new SPAlertTemplateCollection(WebService); foreach (SPAlertTemplate SPAT in colSPAT) { if (SPAT.Name.Contains(".Ext")) { SPAT.Delete(); } } foreach (SPAlertTemplate SPAT in colSPAT) { if (SPAT.Name.Contains("SPAlertTemplateType")) { SPAlertTemplate newSPAT = new SPAlertTemplate(); XmlDocument xmlSpit = new XmlDocument(); xmlSpit.LoadXml(SPAT.Xml.ToString()); //create node and add value XmlNode node = xmlSpit.CreateNode(XmlNodeType.Element, "Properties", string.Empty); //create 3 nodes XmlNode nodeAssembly = xmlSpit.CreateElement("NotificationHandlerAssembly"); XmlNode nodeClassName = xmlSpit.CreateElement("NotificationHandlerClassName"); XmlNode nodeProperties = xmlSpit.CreateElement("NotificationHandlerProperties"); nodeAssembly.InnerText = ourAssemblyName; nodeClassName.InnerText = ourAssemblyName.Substring(0,ourAssemblyName.IndexOf(",")) + "." + ClassToAdd; //add to parent node node.AppendChild(nodeAssembly); node.AppendChild(nodeClassName); node.AppendChild(nodeProperties); //add to elements collection xmlSpit.DocumentElement.AppendChild(node); newSPAT.Xml = xmlSpit.InnerXml; newSPAT.Name = SPAT.Name.ToString() + ".Ext"; newSPAT.Id = Guid.NewGuid(); colSPAT.Add(newSPAT); } } foreach (SPTimerServiceInstance timerservice in WebApplication.Farm.TimerService.Instances) { timerservice.Stop(); timerservice.Start(); } } public override void FeatureDeactivating(SPFeatureReceiverProperties properties) { SPWebApplication WebApplication = (SPWebApplication)properties.Feature.Parent; SPWebService WebService = WebApplication.WebService; SPAlertTemplateCollection colSPAT = new SPAlertTemplateCollection(WebService); foreach (SPAlertTemplate SPAT in colSPAT) { if (SPAT.Name.Contains(".Ext")) { SPAT.Delete(); } } } } }
自定义通知处理程序组装
1类CCPersonalClass实现了包含定义方法的IalertNotifyHandler接口
-
将自定义警报发送(如果它失败发送正常警报)
-
自定义警报:
-
从用户信息列表中获取UsifalEmail字段数据
-
如果个人电子邮件是空的,它只是发送正常警报
-
如果填充了个人电子邮件
-
将正常电子邮件发送到内部电子邮件
-
将缩小的电子邮件发送到外部地址
-
用
http://
替换http://ext-
-
如果发送外部电子邮件删除所有细节记录,只需留下标题。

设置使用外部模板 的警报
1现有内容使用功能事件接收器更新:
-
现有警报:
- site.allwebs.alerts会变为与之与.ext附加的相同的模板名称
-
现有列表:
- site.allwebs.lists将附加的警报翻转到他们的.ext对手
{
.using System; using System.Runtime.InteropServices; using System.Security.Permissions; using Microsoft.SharePoint; using Microsoft.SharePoint.Security; using Prov.Framework.Logger; namespace Prov.Shared.CCPersonalEmail.Features.CCAlerts { [Guid("a3889d39-ea91-441e-9039-157c512441e4")] public class CCAlertsEventReceiver : SPFeatureReceiver { // Set AlertTemplates on sites and alerts to custom templates. public override void FeatureActivated(SPFeatureReceiverProperties properties) { using (SPSite site = (SPSite)properties.Feature.Parent) { AlertTemplateSelector objSelectedAlertTemplate = new AlertTemplateSelector(site); //Add PersonalEmail field if it does not exist yet SPFieldCollection UserInfoFields = site.RootWeb.Lists["User Information List"].Fields; try { bool FieldExists = UserInfoFields.ContainsField("PersonalEmail"); if (!FieldExists) { UserInfoFields.Add("PersonalEmail", SPFieldType.Text, false); } } catch (Exception e) { Logger.LogError(e, "CCPersonalClass"); } foreach (SPWeb web in site.AllWebs) { using (web) { web.AllowUnsafeUpdates = true; foreach (SPList List in web.Lists) { try { List.AlertTemplate = objSelectedAlertTemplate.SwapAlertTemplate(List.AlertTemplate.Name, true); List.Update(); } catch (Exception e) { Logger.LogError(e, "CCAlertsEventReceiver"); } } foreach (SPAlert Alert in web.Alerts) { try { Alert.AlertTemplate = objSelectedAlertTemplate.SwapAlertTemplate(Alert.AlertTemplate.Name, true); Alert.Update(); } catch (Exception e) { Logger.LogError(e, "CCAlertsEventReceiver"); } } web.AllowUnsafeUpdates = false; } } } } // Revert AlertsTemplates on sites and alerts back to out of box templates. public override void FeatureDeactivating(SPFeatureReceiverProperties properties) { using (SPSite site = (SPSite)properties.Feature.Parent) { AlertTemplateSelector objSelectedAlertTemplate = new AlertTemplateSelector(site); foreach (SPWeb web in site.AllWebs) { using (web) { web.AllowUnsafeUpdates = true; foreach (SPList List in web.Lists) { try { List.AlertTemplate = objSelectedAlertTemplate.SwapAlertTemplate(List.AlertTemplate.Name, false); List.Update(); } catch (Exception e) { Logger.LogError(e, "CCAlertsEventReceiver"); } } foreach (SPAlert Alert in web.Alerts) { try { Alert.AlertTemplate = objSelectedAlertTemplate.SwapAlertTemplate(Alert.AlertTemplate.Name, false); Alert.Update(); } catch (Exception e) { Logger.LogError(e, "CCAlertsEventReceiver"); } } web.AllowUnsafeUpdates = false; } } } } } }
通过功能激活,取消激活和onlistCreation事件处理程序 ,使用以下代码
{
.using System; using System.Collections.Generic; using System.Linq; using System.Text; using Microsoft.SharePoint.Administration; using Microsoft.SharePoint; namespace Shared.CCPersonalEmail { class AlertTemplateSelector { private SPAlertTemplateCollection atc; private SPSite site; public AlertTemplateSelector(SPSite site) { this.site = site; this.atc = new SPAlertTemplateCollection((SPWebService)site.WebApplication.Parent); } public SPAlertTemplate SwapAlertTemplate(string PreviousAlert, bool isActivating) { if ((!PreviousAlert.EndsWith(".Ext")) && (isActivating)) { PreviousAlert = string.Format("{0}.Ext", PreviousAlert); } if ((PreviousAlert.EndsWith(".Ext")) && (!isActivating)) { PreviousAlert = PreviousAlert.Replace(".Ext", ""); } SPAlertTemplate newTemplate = atc[PreviousAlert]; if (newTemplate == null) { if (isActivating) { newTemplate = atc["SPAlertTemplateType.GenericList.Ext"]; } else { newTemplate = atc["SPAlertTemplateType.GenericList"]; } } return newTemplate; } } }
2未来的网页及其未来列表
- splasteventreceiver listadded()事件在网站集中创建的所有列表中翻转模板
{
.namespace Shared.CCPersonalEmail.OnListCreation { public class OnListCreation : SPListEventReceiver { public override void ListAdded(SPListEventProperties properties) { base.ListAdded(properties); SPWeb web = properties.Web; SPList List = web.Lists[properties.ListId]; AlertTemplateSelector objSelectedAlertTemplate = new AlertTemplateSelector(web.Site); List.AlertTemplate = objSelectedAlertTemplate.SwapAlertTemplate(List.AlertTemplate.Name, true); List.Update(); } } }
家政
1在特征激活期间
-
在rootweb的用户信息列表中创建一个personalemail字段
-
代码包含在 上方的特征激活事件接收器中
2在功能停用期间
- pustryemail成为内容,因此在停用时不会删除
-
- splasteventreceiver listadded()事件在网站集中创建的所有列表中翻转模板
- site.allwebs.lists将附加的警报翻转到他们的.ext对手

其他提示
如果它是孤立的只需一个列表,您可能可以使用工作流程。您可以创建一个保留列表,以跟踪电子邮件的类型,并分号分隔的电子邮件地址列表。当创建或编辑项目时(无论您的警报逻辑应该是什么),您可以查找相应的电子邮件地址列表,并将其进行调查的电子邮件。
