javascript - 如何使用 JavaScript 获取 REST 客户端？

Question

Visual studios 在其网站上有以下 typescript 代码，我试图将其作为示例:

import RestClient = require("TFS/WorkItemTracking/RestClient");
 // Get an instance of the client
var client = RestClient.getClient();
// Call a method on the client
// e.g. client.getResource(...).then(...);

我的部分 JavaScript 代码是:

VSS.init({
        explicitNotifyLoaded: true,
        usePlatformStyles: true
    });
  VSS.require([
      "VSS/Controls",
      "VSS/Controls/Menus",
      "VSS/Controls/Dialogs",
      "VSS/Service",
      "TFS/WorkItemTracking/RestClient",
      "VSS/WebApi/Contracts"],
      function (VSS_Service, TFS_Wit_WebApi) {
          //get the REST client
          var witClient = VSS_Service.getCollectionClient(TFS_Wit_WebApi.WorkItemTrackingHttpClient);
      }
  );

但是，当我这样做时，我收到一条错误，指出 VSS_Service.getCollectionClient(TFS_Wit_WebApi.WorkItemTrackingHttpClient) 不是函数。除了 VSS.require(["VSS/Service"] 之外，我是否还需要初始化 VSS_Service？

我制作了 witClient 和外部变量，以便我可以在程序中的任何位置使用它，并将控件和网格添加到有效的函数中。

var witClient;
  VSS.init({
        explicitNotifyLoaded: true,
        usePlatformScripts: true, 
        usePlatformStyles: true
    });
  VSS.require([
      "VSS/Controls", "VSS/Controls/Grids",
      "VSS/Service", "TFS/WorkItemTracking/RestClient"],
      function (Controls, Grids, VSS_Service, TFS_Wit_WebApi) {
          //get the REST client
          witClient = VSS_Service;//.getCollectionClient(TFS_Wit_WebApi.WorkItemTrackingHttpClient);
          witClient = witClient.getCollectionClient(TFS_Wit_WebApi.WorkItemTrackingHttpClient);
      }
  );
