前言

　　最近，接到一个需求，用户希望通过自定义代码，获取SharePoint文档库中文档的版本，好的，安排！

　　正文

　　1.获取版本的REST API，通过Get方法进行调用，如下图：

1 $.ajax
 2 ({
 3     url:"https://aiacom.sharepoint.com/sites/TEST/_api/web/GetFileByServerRelativeUrl('/sites/TEST/Shared Documents/TestForVersion.docx')/versions",
 4     type: "GET",
 5     headers:
 6     {
 7        "Accept": "application/json;odata=verbose"
 8     },
 9     success: function (data, status, xhr) {
10     console.log(data);
11     var dataresults = data.d.results;
12     for (var i = 0; i < dataresults.length; i++) {
13         console.log("Version: " + dataresults[i]["VersionLabel"] + ", Url: " + dataresults[i]["Url"]);
14     }
15     },
16     error: function (xhr, status, error) {
17         console.log("Failed");
18     }
19 });

　　2.恢复文档的对应版本为主版本，如下图：

1 $.ajax
 2 ({
 3     url:"https://aiacom.sharepoint.com/sites/TEST/_api/web/GetFileByServerRelativeUrl('/sites/TEST/Shared Documents/TestForVersion.docx')/versions/restorebylabel(versionlabel='1.0')",
 4     type: "POST",
 5     headers:
 6     {
 7        "Accept": "application/json;odata=verbose",
 8        "Content-Type": "application/json;odata=verbose",
 9        "IF-MATCH": "*",
10        "X-HTTP-Method": "PATCH",
11        "X-RequestDigest": $("#__REQUESTDIGEST").val()
12     },
13     success: function (data, status, xhr) {
14         console.log("success");
15     },
16     error: function (xhr, status, error) {
17         console.log("Failed");
18     }
19 });
20 }

　　3.调用API返回的结果
