使用SharePoint Web服务/对象模型批准SharePoint工作流任务

我创建的工作流是SharePoint Designer,并将其与列表相关联。工作流创建批准过程,因此SharePoint在“任务”列表中创建任务,以便用户可以批准或拒绝。

我需要做的是在不打开任务列表中的任务的情况下批准或拒绝任务。经过一些研究后,我发现我可以使用SharePoint Web Services。但是我感到迷茫,因为我不知道哪种服务,例如Lists.asmx,以及哪种方法,例如UpdateListItems,要调用。

有人可以通过以下方式指导我:
1-批准工作流任务SharePoint Web Services是否可行? 2-你能告诉我一个如何批准任务的例子,例如要调用哪种服务和方法以及参数应该是什么?

更新
我一直在使用以下XML来设置完成工作流程:

 batchElement.InnerXml = "<Method ID='1' Cmd='Update'>" // Also used Moderate
                + "<Field Name='ID'>115</Field>"
                + "<Field Name='Status'>Completed</Field>"
                + "<Field Name='FormData'>Completed</Field>" // Also used Approved
                + "<Field Name='WorkflowOutcome'>Approved</Field>"
                + "<Field Name='Completed'>True</Field>"
                + "<Field Name='PercentComplete'>1</Field>"
                + "<Field Name='_ModerationStatus'>0</Field>"
                + "</Method>";

任务列表项已更新,但WorkflowOutcome仍为空,工作流程未移至下一步。
我还缺少什么?

更新#2
我怀疑任务列表项的ExtendedProperties。对于使用UI完成的项目,ExtendedProperties显示ws_TaskStatus ='已批准'。但是,对于使用代码批准的项目,ws_TaskStatus不存在。

更新#3
从MSDN帖子中,我被告知要使用Workflow.asmx而不是Lists.asmx 我使用了以下代码:

WorkflowService.Workflow listProxy = new WorkflowService.Workflow();
listProxy.Url = "http://<server_name>/_vti_bin/workflow.asmx";
listProxy.UseDefaultCredentials = true;

int todoID = 118;
Guid tasklistID = new Guid("{79ABFDE7-0398-4AD7-918A-0D40204E7726}");
string itemURL = "http://<server_name>/TestLibrary/volshext.log";
XmlDocument taskData = new XmlDocument();
taskData.Load(@"..\..\TaskData.xml");

try
{
   XmlNode response = listProxy.AlterToDo(itemURL, todoID, tasklistID, taskData.DocumentElement);
   Console.WriteLine(response.InnerText);
}

我用来批准任务的XML是

<my:myFields xmlns:my="http://schemas.microsoft.com/office/infopath/2003/myXSD" >
 <my:TaskStatus>#</my:TaskStatus>
 <my:Comments />
 <my:DelegateTo />
 <my:NewDescription>Please approve Workflow Demo</my:NewDescription>
 <my:NewDueDate />
 <my:RequestTo />
 <my:Decline>0</my:Decline>
 <my:dcr>0</my:dcr>
 <my:Status>Completed</my:Status>
</my:myFields>

但是,任务再次更新,但工作流程没有继续前进。

更新#4
我已经使用SharePoint服务器对象模型进行了最后一次试用,但同样,任务已更新,但工作流程未向前推进。
这是我的代码:

SPSite site = new SPSite("http://sitenamehere/");
using (SPWeb web = site.OpenWeb())
{
   SPList list = web.Lists["Shared Documents"];
   //SPListItem item = list.GetItemById(18);
   SPListItem item = list.GetItemByUniqueId(new Guid("5300d16e-94f8-4338-8206-4a57ab7c369b"));
   SPWorkflow workflow = item.Workflows[0];
   SPWorkflowTask task = workflow.Tasks[0];
   Hashtable ht = new Hashtable();
ht[SPBuiltInFieldId.Completed] = "TRUE"; ht["Completed"] = "TRUE"; ht[SPBuiltInFieldId.PercentComplete] = 1.0f; ht["PercentComplete"] = 1.0f; ht["Status"] = "Completed"; ht[SPBuiltInFieldId.TaskStatus] = SPResource.GetString(new CultureInfo((int)task.Web.Language, false), Strings.WorkflowStatusCompleted, new object[0]); //ht["TaskStatus"] = "#"; //ht["ows_TaskStatus"] = "Approved"; //ht["FormData"] = SPWorkflowStatus.Completed; //ht["Outcome"] = "Approved"; //task.ModerationInformation.Status = SPModerationStatusType.Approved;
web.AllowUnsafeUpdates = true; SPWorkflowTask.AlterTask((task as SPListItem), ht, true); }

经过大量的试验和调查后,我只是使用以下代码来批准任务

SPSite site = new SPSite("http://servername/");
using (SPWeb web = site.OpenWeb())
{
    SPList list = web.Lists["TestList"];
    SPListItem item = list.GetItemById(22);
    SPWorkflow workflow = item.Workflows[0];
    SPWorkflowTask task = workflow.Tasks[0];

    Hashtable ht = new Hashtable();             
    ht[SPBuiltInFieldId.Completed] = "TRUE";
    ht["Completed"] = "TRUE";
    ht[SPBuiltInFieldId.PercentComplete] = 1.0f;
    ht["PercentComplete"] = 1.0f;
    ht["Status"] = "Completed";
    ht[SPBuiltInFieldId.TaskStatus] = SPResource.GetString(new CultureInfo((int)task.Web.Language, false), Strings.WorkflowStatusCompleted, new object[0]);
    ht[SPBuiltInFieldId.WorkflowOutcome] = "Approved";
    ht["TaskStatus"] = "Approved";
    ht["FormData"] = SPWorkflowStatus.Completed;

    web.AllowUnsafeUpdates = true;
    SPWorkflowTask.AlterTask((task as SPListItem), ht, true);
}

我怀疑ht["TaskStatus"] = "Approved";是解决它的属性。无论如何,我会尝试缩小需要更改的属性集。

您可以使用以下使用列表Web服务和UpdateListItems方法的代码。关键是使用Cmd ='中等'

 public static XmlNode UpdateListItemApprove()
 {
            listservice.Lists listProxy = new listservice.Lists();


            string xml = "<Batch OnError='Continue'><Method ID='1' Cmd='Moderate'><Field Name='ID'/><Field Name='FileRef'>http://basesmcdev2/sites/tester1/approvals/KL022030.lic</Field><Field Name=\"_ModerationStatus\" >0</Field></Method></Batch>";

            XmlDocument doc = new XmlDocument();
            doc.LoadXml(xml);

            XmlNode batchNode = doc.SelectSingleNode("//Batch");

            listProxy.Url = "http://basesmcdev2/sites/tester1/_vti_bin/lists.asmx";
            listProxy.UseDefaultCredentials = true;

            XmlNode resultNode = listProxy.UpdateListItems("approvals", batchNode);

            return resultNode;


}

我不确定Madhur的解决方案是否适用于相关项目或任务,但尝试更新任务:

<?xml version="1.0" encoding="utf-8"?>
<soap:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:xsd="http://www.w3.org/2001/XMLSchema"

<soap:Body>
<UpdateListItems
