通过 URL 将文件夹名称传递给自定义 ASPX 页面中的 SPO Rest API 调用

Question

我有一页列出不同的文件夹 URL。单击该链接应使用从第一页的 URL 传递的参数触发第二页上的以下代码。

我正在尝试通过 URL 传递文件夹名称参数以在 SPO 上的自定义 ASPX 页面中加载 API 调用。链接到下面第二页代码的 URL 将包含文件夹详细信息。

第一页的 URL 格式 - <<<SPO_SITE>>>/teams/<<<SPO_TENANT>>>/SiteAssets/Image.aspx?Folder="<<<FOLDER_NAME>>>"

<link rel="stylesheet" href="css/bootstrap.min.css">
<script src="js/jquery-3.5.1.min.js"></script>
<script>
   $(function(){
           var requestUri = "<<<SPO_SITE>>>/teams/<<<SPO_TENANT>>>/_api/web/getfolderbyserverrelativeurl('<<<SPO_DOC_LIB>>>/<<<FOLDER>>>')/Files?$top=2000&$select=ServerRelativeUrl";
              $.ajax({
                 url: requestUri,
                 type: "GET",
                 headers: {
                     "accept":"application/json; odata=verbose"
                 },
                 success: onSuccess,
   });
   
     function onSuccess(data) {
        var objItems = data.d.results;
   
        var divContent = '<div class="row" id="myList">';
        for (var i = 0; i < objItems.length; i++) {
   
            divContent += '<div class="col-md-3"><div class="card mb-4 shadow-sm"><img src="<<<SPO_SITE>>>/' + objItems[i].ServerRelativeUrl + '"><a class="stretched-link" target="_blank" href="<<<SPO_SITE>>>/' + objItems[i].ServerRelativeUrl + '"></a></div></div>';
   
    }
      $('#ImgGrid').append(divContent);
      }
   });
</script>
<main role="main">
   <section class="pt-4 pb-4 text-center">
      <div class="container">


      </div>
   </section>
   <div class="container">
      <div id="myList">
         <div id="ImgGrid"></div>
      </div>
   </div>
</main>

<script src="js/popper.min.js"></script>
<script src="js/bootstrap.bundle.min.js"></script>

请查看代码和建议。

如果图片在这样的 url 中：

https://Tenantname.sharepoint.com/sites/sitename/SPO_DOC_LIB/FOLDER

然后在getfolderbyserverrelativeurl中请像这样传递相对url：

/_api/web/getfolderbyserverrelativeurl('/sites/sitename/>>/>')/Files?$top=2000&$select=ServerRelativeUrl

用完整的代码更新sn-p：

   <link rel="stylesheet" href="https://stackpath.bootstrapcdn.com/bootstrap/3.4.1/css/bootstrap.min.css" />
    <script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.5.1/jquery.min.js"></script>
    <script src="https://cdnjs.cloudflare.com/ajax/libs/popper.js/2.6.0/umd/popper.min.js"></script>
    <script src="https://stackpath.bootstrapcdn.com/bootstrap/3.4.1/js/bootstrap.min.js"></script>
    <script>
        $(function () {
        var relativeurl = "/sites/dev/Share Documents/" + GetParameterValues("Folder");
        var requestUri = _spPageContextInfo.webAbsoluteUrl +"/_api/web/getfolderbyserverrelativeurl('"+relativeurl+"')/Files?$top=2000&$select=ServerRelativeUrl";
        $.ajax({
            url: requestUri,
            type: "GET",
            headers: {
                "accept": "application/json; odata=verbose"
            },
            success: onSuccess,
        });


        });

        function onSuccess(data) {
            var objItems = data.d.results;
            console.log(objItems);
            var divContent = '<div class="row" id="myList">';
            for (var i = 0; i < objItems.length; i++) {

                divContent += '<div class="col-md-3"><div class="card mb-4 shadow-sm"><img src="' + objItems[i].ServerRelativeUrl + '"><a class="stretched-link" target="_blank" href="' + objItems[i].ServerRelativeUrl + '"></a></div></div>';

            }
            $('#ImgGrid').append(divContent);
        }

        function GetParameterValues(param) {
            var url = window.location.href.slice(window.location.href.indexOf('?') + 1).split('&');
            for (var i = 0; i < url.length; i++) {
                var urlparam = url[i].split('=');
                if (urlparam[0] == param) {
                    return urlparam[1];
                }
            }
        }
    </script>

<main role="main">
    <section class="pt-4 pb-4 text-center">
        <div class="container">


        </div>
    </section>
    <div class="container">
        <div id="myList">
            <div id="ImgGrid"></div>
        </div>
    </div>

在上面的代码演示中，我的网址是https://tenant.sharepoint.com/sites/dev/

所以相对 url 使用的是 /sites/dev/Shared Documents/folder1

更新：

在第二页的url中获取文件夹查询字符串参数如下：

JSRequest.EnsureSetup();
var itemId = JSRequest.QueryString["Folder"];
