在共享点设计器的工作流编辑器中,如何获取工作流发起者用户名?
在 Sharepoint 设计器的工作流程编辑器中,我希望检索工作流程发起者的用户名/名称(即谁启动或触发了工作流程) - 使用 3rd 方产品(例如 Nintex Workflow 2007)(我将在其中使用类似于 {Common:Initiator}) - 但我似乎找不到任何开箱即用的方法来使用共享点设计器和 MOSS 2007 来执行此操作。
更新
它看起来并不那么明显支持 OOTB 功能,因此我最终编写了一个自定义活动(如答案之一所建议)。 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实例,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>
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.
Update
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;
}
}
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>

我认为这不可能在 SharePoint Designer 中开箱即用地实现。 您可能可以编写一个自定义操作来获取发起者,但我认为它根本不通过 SPD 工作流界面公开。
您可能做的最好的事情就是获取创建或修改列表中项目的用户,但这不能处理手动运行工作流的情况。
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.
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.
我可以通过仅使用 SPD 来考虑一种简单但不是非常复杂的解决方案。 只需在工作流程步骤中,在辅助列表(可能是存储工作流程 ID 和 itemId 属性以供参考的任务列表)中创建一个测试项目,然后在工作流程中对该列表进行查找以查看谁是该项目的创建者,即value 将是当前工作流发起者。
I can think about a simple but not very sophisticated solution for this one by using just SPD. Just in workflow steps create a test item in a secondary list (probably a task list which stores the workflowId and itemId properties for refrence back) and then do a lookup in your workflow on that list to see who is the creator of that item, that value would be the current workflow initiator.
自定义活动解决方案仅在您使用 moss 时才有效,如果您只有 wss 3.0,您可以在工作流程中多放一步并设置包含任何信息的自定义注释字段,这使得最后修改的人发生更改并变得相同作为工作流发起者,您可以使用 ModifiedBy 字段做出您需要的任何决定。
The custom activity solution only work if you are working with moss, if you only have wss 3.0 you can put one step more in your workflow and set a custom comment field with any information, this make the last modified person to change and become the same as the workflow initiator, then you can use the ModifiedBy field to make any decision that you need.
对于通过 google 搜索本文并正在使用 SharePoint 2010 的用户来说,工作流启动器变量现在在 SharePoint Designer 中受 OOTB 支持。
数据源将是“工作流程上下文”,字段当然是“发起者”,您可以选择将其返回为“显示名称”、“电子邮件”、“登录名称”或“用户 ID 号”
For those that google into this article and are now using SharePoint 2010, the workflow initiator variable is now supported OOTB in SharePoint Designer.
The datasource would be "Workflow Context" and the field is, of course, "Initiator" and you can choose to return it as the "Display Name", "Email", "Login Name" or the "User ID Number"
