是否可以将远程事件接收器附加到我的列表中

Question

是否可以将远程事件接收器附加到我的网站上的现有列表中，而不是我的应用程序中的列表？我猜我没有找到它的任何东西，我认为这可能是“伤害”的SharePoint。

如果我需要得到它的工作，我需要看一个沙箱或农场解决方案吗？

Answer 1

我会说不可能将远程事件接收器附加到主机Web中的列表，因为这些实际上是跨站点集合。

在主机Web中，您只能部署常规事件接收器（针对程序集中的类），远程事件接收器将实际WCF的URL作为目标，其在主机中不存在无论如何，网址：

<Url>~remoteAppUrl/RemoteEventReceiver1.svc</Url>

.

或

<Url>http://apps.mydomain.com:36511/MyReR.svc</Url>

.

是的，是可能的。 只需在按照下面播种时将属性属性更改为true，在安装应用程序时处理事件接收器。

然后只是写下以下代码

public SPRemoteEventResult ProcessEvent(SPRemoteEventProperties properties)
        {
            SPRemoteEventResult result = new SPRemoteEventResult();

            switch (properties.EventType)
            {
                case SPRemoteEventType.AppInstalled:
                    HandleAppInstalled(properties);
                    break;
                case SPRemoteEventType.ItemAdded:
                    HandleItemAdded(properties);
                    break;
            }
            return result;
        }

        private void HandleAppInstalled(SPRemoteEventProperties properties)
        {
            using (ClientContext clientContext =
                      TokenHelper.CreateAppEventClientContext(properties, false))
            {
                if (clientContext != null)
                {
                    List myList = clientContext.Web.Lists.GetByTitle("Your List Name");
                    clientContext.Load(myList, p => p.EventReceivers);
                    clientContext.ExecuteQuery();
                    bool rerExists = false;

                    foreach (var rer in myList.EventReceivers)
                    {
                        if (rer.ReceiverName == "ItemAddedEvent")
                        {
                            rerExists = true;
                            System.Diagnostics.Trace.WriteLine("Found existing ItemAdded receiver at "
                               + rer.ReceiverUrl);
                        }
                    }
                    if (!rerExists)
                    {
                        EventReceiverDefinitionCreationInformation receiver =new EventReceiverDefinitionCreationInformation();
                        receiver.EventType = EventReceiverType.ItemAdded;


                        receiver.ReceiverUrl = "Your service url";
                        receiver.ReceiverName = "ItemAddedEvent";
                        receiver.Synchronization = EventReceiverSynchronization.Synchronous;
                        myList.EventReceivers.Add(receiver);
                        clientContext.ExecuteQuery();
                        System.Diagnostics.Trace.WriteLine("Added ItemAdded receiver at " + msg.Headers.To.ToString());
                    }
                }
            }
        }
 private void HandleItemAdded(SPRemoteEventProperties properties)
        {
            using (ClientContext clientContext =
              TokenHelper.CreateRemoteEventReceiverClientContext(properties))
            {
                if (clientContext != null)
                {
                    try
                    {
                        List photos = clientContext.Web.Lists.GetByTitle("Your List Name");
                        ListItem item = photos.GetItemById(
                           properties.ItemEventProperties.ListItemId);
                        clientContext.Load(item);
                        clientContext.ExecuteQuery();

                        item["Title"] += "\nUpdated by RER " +
                             System.DateTime.Now.ToLongTimeString();
                        item.Update();
                        clientContext.ExecuteQuery();
                    }
                    catch (Exception oops)
                    {
                        System.Diagnostics.Trace.WriteLine(oops.Message);
                    }
                }
            }
        }

我希望这会帮助你。

只有以编程方式才能，如果您部署，则无法工作。

var eventReceiver = new EventReceiverDefinitionCreationInformation
                     {
                         EventType = EventReceiverType.ItemAdding,
                         ReceiverAssembly = Assembly.GetExecutingAssembly().FullName,
                         ReceiverClass = "RemoteReciverWeb.Services.ContactAddEventReceiver",
                         ReceiverName = "ContactAddEventReceiver",
                         ReceiverUrl = remoteEventEndPointUrl,
                         SequenceNumber = 1000
                     };

clientContext.Load(eventresevers);
