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"

            <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"/>

        </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。
