Google Drive Api V3 - 检索所有文件夹和文件及其子项作为树视图

Question

有没有办法使用 Google API v3 客户端一次性从 google drive 及其子文件夹或子文件夹中检索文件夹和文件？下面是我现在用来检索的代码，我只获取第一层数据。请任何人告诉我这个。如果满足我的要求，我很感激。 谢谢你。

Answer 1

如果要检索所有文件，则必须使用Files:list 方法。但是，每页可以返回的最大结果数为 1000。

为了检索所有其他剩余文件，您必须使用nextPageToken 参数。

根据Drive API v3 documentation：

nextPageToken > 下一页文件的页面标记。如果到达文件列表的末尾，这将不存在。如果令牌因任何原因被拒绝，则应将其丢弃，并应从结果的第一页重新开始分页。

此外，根据您传递给请求的确切 corpora 参数，incompleteSearch 参数可能也会有所帮助。

Answer 2

这是我在 v8 之前编写的一个真正的旧脚本：

这里的内容可能不是脚本的一部分，但我已经包含了所有内容。

代码.gs：

var GStorage = '';
var folderID = "Storage Folder Id"
var GFlag = 0;
function onOpen()
{
  var ui = SpreadsheetApp.getUi();
  ui.createMenu('My Tools')
            .addItem('My Drive Directory Listing','runtraverseFolder')
            .addItem('Clear Dirlist','clearDirlist')
            .addToUi();
}

function runtraverseFolder()
{
  var dirlist = loadDirlist();
  var html1 = '<html><head></head><body><div class="cntrls"><input type="button" value="Exit" onClick="google.script.host.close()" />&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;\

  var html2 = '</div><div class="cntrls"><input type="button" value="Exit" onClick="google.script.host.close()" />\
  &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<input type="button" value="Delete Cached Listing & Start Over" onClick="google.script.run.clearDirlist();" />\

我在文件中存储了一些片段，因为运行此脚本需要很长时间，所以每次我决定存储我认为如果我正在寻找旧的信息时可能有用的信息，而不是花时间遍历所有文件东西。实际上，我从不使用脚本。你可以就它提出问题，但我不保证回答它们，因为我已经很久没有看过它了。它在 Rhino 中运行，但我尚未在 v8 中对其进行测试。
