在Sharepoint Designer的工作流编辑器中,如何获取工作流发起者的用户名?
时间:2020-03-06 14:42:07 来源:igfitidea点击:
我希望在Sharepoint Designer的工作流编辑器中检索工作流发起者的用户名/名称(即谁启动或者触发了工作流),这相对容易使用第三方产品(例如Nintex Workflow 2007)来完成(在此我将使用某些东西)。像{Common:Initiator}),但使用共享点设计器和MOSS 2007似乎无法找到任何开箱即用的方法。
更新
OOTB似乎不支持此相当明显的功能,因此我最终编写了一个自定义活动(如答案之一所示)。我在这里列出了活动代码以供参考,尽管我怀疑博客上可能会散布一些此类代码,因为这是一个非常简单的解决方案:
public partial class LookupInitiatorInfo : Activity
{
public static DependencyProperty __ActivationPropertiesProperty =
DependencyProperty.Register("__ActivationProperties",
typeof(Microsoft.SharePoint.Workflow.SPWorkflowActivationProperties),
typeof(LookupInitiatorInfo));
public static DependencyProperty __ContextProperty =
DependencyProperty.Register("__Context", typeof (WorkflowContext),
typeof (LookupInitiatorInfo));
public static DependencyProperty PropertyValueVariableProperty =
DependencyProperty.Register("PropertyValueVariable", typeof (string),
typeof(LookupInitiatorInfo));
public static DependencyProperty UserPropertyProperty =
DependencyProperty.Register("UserProperty", typeof (string),
typeof (LookupInitiatorInfo));
public LookupInitiatorInfo()
{
InitializeComponent();
}
[Description("ActivationProperties")]
[ValidationOption(ValidationOption.Required)]
[Browsable(true)]
[DesignerSerializationVisibility(DesignerSerializationVisibility.Visible)]
public Microsoft.SharePoint.Workflow.SPWorkflowActivationProperties __ActivationProperties
{
get { return ((Microsoft.SharePoint.Workflow.SPWorkflowActivationProperties)(base.GetValue(__ActivationPropertiesProperty))); }
set { base.SetValue(__ActivationPropertiesProperty, value); }
}
[Description("Context")]
[ValidationOption(ValidationOption.Required)]
[Browsable(true)]
[DesignerSerializationVisibility(DesignerSerializationVisibility.Visible)]
public WorkflowContext __Context
{
get { return ((WorkflowContext)(base.GetValue(__ContextProperty))); }
set { base.SetValue(__ContextProperty, value); }
}
[Description("UserProperty")]
[ValidationOption(ValidationOption.Required)]
[Browsable(true)]
[DesignerSerializationVisibility(DesignerSerializationVisibility.Visible)]
public string UserProperty
{
get { return ((string) (base.GetValue(UserPropertyProperty))); }
set { base.SetValue(UserPropertyProperty, value); }
}
[Description("PropertyValueVariable")]
[ValidationOption(ValidationOption.Required)]
[Browsable(true)]
[DesignerSerializationVisibility(DesignerSerializationVisibility.Visible)]
public string PropertyValueVariable
{
get { return ((string) (base.GetValue(PropertyValueVariableProperty))); }
set { base.SetValue(PropertyValueVariableProperty, value); }
}
protected override ActivityExecutionStatus Execute(ActivityExecutionContext executionContext)
{
// value values for the UserProperty (in most cases you
// would use LoginName or Name)
//Sid
//ID
//LoginName
//Name
//IsDomainGroup
//Email
//RawSid
//Notes
try
{
string err = string.Empty;
if (__ActivationProperties == null)
{
err = "__ActivationProperties was null";
}
else
{
SPUser user = __ActivationProperties.OriginatorUser;
if (user != null && UserProperty != null)
{
PropertyInfo property = typeof (SPUser).GetProperty(UserProperty);
if (property != null)
{
object value = property.GetValue(user, null);
PropertyValueVariable = (value != null) ? value.ToString() : "";
}
else
{
err = string.Format("no property found with the name \"{0}\"", UserProperty);
}
}
else
{
err = "__ActivationProperties.OriginatorUser was null";
}
}
if (!string.IsNullOrEmpty(err))
Common.LogExceptionToWorkflowHistory(new ArgumentOutOfRangeException(err), executionContext,
WorkflowInstanceId);
}
catch (Exception e)
{
Common.LogExceptionToWorkflowHistory(e, executionContext, WorkflowInstanceId);
}
return ActivityExecutionStatus.Closed;
}
}
然后将其与以下.action xml文件连接起来:
<?xml version="1.0" encoding="utf-8"?>
<WorkflowInfo Language="en-us">
<Actions>
<Action Name="Lookup initiator user property"
ClassName="XXX.ActivityLibrary.LookupInitiatorInfo"
Assembly="XXX.ActivityLibrary, Version=1.0.0.0, Culture=neutral, PublicKeyToken=XXX"
AppliesTo="all"
Category="WormaldWorkflow Custom Actions">
<RuleDesigner Sentence="Lookup initating users property named %1 and store in %2">
<FieldBind Field="UserProperty" DesignerType="TextArea" Id="1" Text="LoginName" />
<FieldBind Field="PropertyValueVariable" DesignerType="ParameterNames" Text="variable" Id="2"/>
</RuleDesigner>
<Parameters>
<Parameter Name="__Context" Type="Microsoft.Sharepoint.WorkflowActions.WorkflowContext, Microsoft.SharePoint.WorkflowActions" Direction="In"/>
<Parameter Name="__ActivationProperties" Type="Microsoft.SharePoint.Workflow.SPWorkflowActivationProperties, Microsoft.SharePoint" Direction="In"/>
<Parameter Name="UserProperty" Type="System.String, mscorlib" Direction="In" />
<Parameter Name="PropertyValueVariable" Type="System.String, mscorlib" Direction="Out" />
</Parameters>
</Action>
</Actions>
</WorkflowInfo>
解决方案
我认为这在开箱即用的SharePoint Designer中是不可能的。我们可能可以编写一个自定义动作来获取发起者,但是我完全不相信它会通过SPD工作流界面公开。
我们可能要做的最好的事情就是让创建或者修改列表中项目的用户,但这无法处理手动运行工作流的情况。
我可以考虑仅使用SPD来解决此问题的简单但不是非常复杂的解决方案。仅在工作流步骤中,在辅助列表(可能是一个任务列表,其中存储了工作流ID和itemId属性以供回溯)中创建一个测试项目,然后在工作流中对该列表进行查找以查看谁是该项目的创建者,值将是当前的工作流发起者。
