使用 webserivces 在其他 sharepoint 网站上写

Question

我有 2 个 Sharepoint 2013 网站。当用户在第一个 SPSite 的 SPList 中添加新项目 -> 开始工作流时，必须在第二个 SPSite 的 SPList 中添加项目的副本。这是我的代码：

   public void UpdateSPList(string Title)
        {
            using (AuthenticationSvc.Authentication authSvc = new AuthenticationSvc.Authentication())
            {
                    try
                    {
                        using (ListsSvc.Lists list = new ListsSvc.Lists())
                        {
                            list.Url = @"http://second-srharepoint-site.com/_vti_bin/Lists.asmx";
                            list.CookieContainer = new System.Net.CookieContainer();
                            list.AllowAutoRedirect = true;
                            list.PreAuthenticate = true;

                            list.Credentials = new System.Net.NetworkCredential("domain\username", "password");


                            string strBatch = "<Method Cmd='New'><Field Name='Title'>" + Title + "</Field> ";

                            XmlDocument xmlDoc = new XmlDocument();
                            XmlElement elBatch = xmlDoc.CreateElement("Batch");
                            elBatch.SetAttribute("OnError", "Continue");

                            elBatch.InnerXml = strBatch;
                            XmlNode ndReturn = list.UpdateListItems("SPListName", elBatch);   


                        }
                    }
                    finally
                    {

                    }

            }

        }

但在线 elBatch.InnerXml = strBatch; 我得到异常：

$exception {"Unexpected end of file has occurred. The following elements are not closed: Method. Line 1, position 60."} System.Exception {System.Xml.XmlException}

我不知道如何解决这个问题。请帮助我。

Answer 1

首先，该字符串无效 XML，因为缺少结束 Method 元素。应该是

"<Method Cmd='New'><Field Name='Title'>" + Title + "</Field></Method>"

其次，早在 2010 年就弃用了 ASMX 服务。您不应该将它们用于任何开发之王，尤其是针对 SP 2013。客户端对象模型 (CSOM) 很多更简单易用。文档中有 a lot 个示例。创建新项目的代码段是：

// Starting with ClientContext, the constructor requires a URL to the 
// server running SharePoint. 
ClientContext context = new ClientContext("http://SiteUrl"); 

// Assume that the web has a list named "Announcements". 
List announcementsList = context.Web.Lists.GetByTitle("Announcements"); 

// We are just creating a regular list item, so we don't need to 
// set any properties. If we wanted to create a new folder, for 
// example, we would have to set properties such as 
// UnderlyingObjectType to FileSystemObjectType.Folder. 
ListItemCreationInformation itemCreateInfo = new ListItemCreationInformation(); 
ListItem newItem = announcementsList.AddItem(itemCreateInfo); 
newItem["Title"] = "My New Item!"; 
newItem["Body"] = "Hello World!"; 
newItem.Update(); 

context.ExecuteQuery();

无需 XML 摆弄，您只需创建一个新项目，设置其属性并调用 Update
