I have a SharePoint 2013 List with versioning enabled. I need to to get SPListItem versions list via REST. I can get SPListItem by that request: http://spbreportportal/Projects/_api/lists/getbytitle('Projects')/Items(1) But I can't find in documentation and in response how to retrieve all versions of this item. Is it possible?

推荐答案

似乎无法通过 REST/CSOM API 获取 List Item 的版本，但有替代选项

It does not seem possible to get versions for a List Item via REST/CSOM APIs, but there are alternative options

想法是对版本页面执行获取请求:http://<server>/<site>/_layouts/versions.aspx?list={litsID}&ID=<itemID>

The idea is to perform a get request to Versions page: http://<server>/<site>/_layouts/versions.aspx?list={litsID}&ID=<itemID>

function getItemVersions(url,listId,itemId,success)
{
   var versionsUrl = url + '/_layouts/versions.aspx?list=' + listId + '&ID=' + itemId;  
   $.get( versionsUrl, function( data ) {
      var versionEntries = parseVersionList(data);
      success(versionEntries);
   });
}


function parseVersionList(data){
   var entries = {};
   var versionList = $(data).find('table.ms-settingsframe');


   versionList.find('tbody > tr').each(function(i){
     if(i > 0 && (i-1) % 2 == 0) {
        var verRow = $(this); //get version row
        var propsRow = verRow.next(); //get properties row
        var versionLabel = verRow.find('td:first').html().trim();
        entries[versionLabel] = {};
        //extract item properties from propsRow goes here
        //...
     }

   });   
   return entries;
}


//Usage
var webUrl = _spPageContextInfo.webAbsoluteUrl;
var listId = _spPageContextInfo.pageListId;
var listItemId = 1;
getItemVersions(webUrl,listId,listItemId,function(versionEntries){
  console.log(versionEntries);
});

使用列表 SharePoint Web 服务

另一种选择是利用公开 Lists.GetVersionCollection 方法 返回 SharePoint 列表中指定字段的版本信息

Using Lists SharePoint Web Services

Another option would be to utilize Lists SharePoint Web Services that exposes Lists.GetVersionCollection Method to return version information for the specified field in a SharePoint list

SPServices 示例:

$().SPServices({
  operation: "GetVersionCollection",
  async: false,
  strlistID: "Projects",
  strlistItemID: 1,
  strFieldName: "Description",
  completefunc: function (xData, Status) {
    $(xData.responseText).find("Version").each(function(i) {
      console.log("Name: " + $(this).attr("Description") + " Modified: " + $(this).attr("Modified"));
    });  
  }
});
