在 sharepoint 设计器的工作流编辑器中，如何获取工作流发起者的用户名? [英] In sharepoint designer's workflow editor how do I get the workflow initiators username?
问题描述
在 Sharepoint 设计器的工作流编辑器中，我希望检索工作流发起者的用户名/名称(即谁启动或触发了工作流) - 这相对容易使用 3rd 方产品，例如 Nintex Workflow 2007(其中我会使用像 {Common:Initiator}) 这样的东西 - 但我似乎无法找到任何开箱即用的方法来使用共享点设计器和 MOSS 2007.
In Sharepoint designer's workflow editor I wish to retrieve the username/name of the work flow initiator (i.e. who kicked it off or triggered the workflow) - this is relatively easy to do using 3rd party products such as Nintex Workflow 2007 (where I would use something like {Common:Initiator}) - but I can't seem to find any way out of the box to do this using share point designer and MOSS 2007.
更新
OOTB 似乎不支持这个相当明显的功能，因此我最终编写了一个自定义活动(如其中一个答案所建议的那样).我在这里列出了活动代码以供参考，但我怀疑博客上可能有一些这样的例子，因为这是一个非常简单的解决方案:
It does not look like this rather obvious feature is supported OOTB, so I ended up writing a custom activity (as suggested by one of the answers). I have listed the activities code here for reference though I suspect there are probably a few instances of this floating around out there on blogs as it's a pretty trivial solution:
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:
And then wire it up with the following .action xml file:
<?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>
推荐答案
我认为这在 SharePoint Designer 中开箱即用是不可能的.您可能会编写一个自定义操作来获取发起者，但我认为它根本不会通过 SPD 工作流界面公开.
I don't think this is possible to do in SharePoint Designer out of the box. You could probably write a custom action to get the originator, but I don't believe it is exposed through the SPD workflow interface at all.
您可能做的最好的事情是获取创建或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.
The best you could probably do is get the user who created or modified the item in the list, but this wouldn't handle cases where the workflow was manually run.
