通过Outlook 365插件访问Sharepoint（sp.js）

Question

目标

在Office 365 Outlook加载项中通过JSOM访问Sharepoint。

问题

我尝试了多种方法，其中大多数导致“ 403-禁止使用”。

代码

 // The Office initialize function must be run each time a new page is loaded.
    Office.initialize = function (reason) {
        $(document).ready(function () {
            var element = document.querySelector('.ms-MessageBanner');
            messageBanner = new fabric.MessageBanner(element);
            messageBanner.hideBanner();
            loadProps();

            //app.initialize();
            //Load everything required for sharepoint
            // Get the URI decoded URLs.
            var hostweburl = "https://-tenant here-.sharepoint.com";


            // The js files are in a URL in the form:
            // web_url/_layouts/15/resource_file
            var scriptbase = hostweburl + "/_layouts/15/";

            // Load the js files and continue to
            // the execOperation function.
            $.getScript(scriptbase + "SP.Runtime.js",
                function () {
                    $.getScript(scriptbase + "SP.js", execOperation);
                }
            );



        });
    };

    // Function to execute basic operations.
    function execOperation() {

        //Assure it is running - Doesn't work: SP.SOD does not exist.
        //SP.SOD.executeFunc('sp.js', 'SP.ClientContext', Office.initialize);

        var context = new SP.ClientContext("https://-that same tenant-.sharepoint.com"); // I tired: Get_current(), but I get an error that there is no "current".
        var web = context.get_web();

        var user = web.get_currentUser();

        context.load(user);
        context.executeQueryAsync(Function.createDelegate(this, this.onGetUserQuerySucceeded), Function.createDelegate(this, this.onQueryFailed));
        debugger;

    }

 function onGetListQuerySucceeded() {

        console.log("Hello" + user.get_title());
        console.log(user);
        debugger;
}

function onQueryFailed(sender, args) {
    alert('Request failed. ' + args.get_message() + '\n' + args.get_stackTrace());
}
