数组传递给另一个函数 [英] Pass array to another function

问题描述

我试图改变文件的所有权在谷歌驱动器，在我的服务帐户不是文件的所有者。

I am trying to change ownership of files in Google Drive, where my service account isn't owner of the file.

 function getDriveFiles(folder, path) {
   var folder = DriveApp.getFolderById("0B23heXhtbThYaWdxzMc");
   var path = "";
    var files = [];
    var fileIt = folder.getFiles();
    while ( fileIt.hasNext() ) {
        var f = fileIt.next();
      if (f.getOwner().getEmail() != "[e-mail]")
        files.push({owner: f.getOwner().getEmail(), id: f.getId()});
    }
    return files;
}

所以，我的阵列看起来像这样：

So my array looks like this:

  var files = [
     {owner=[e-mail], id=CjOqUeno3Yjd4VEFrYzg},
     {owner=[e-mail], id=CjOqUYWxWaVpTQ2tKc3c},
     {owner=[e-mail], id=CjOqUNTltdHo2NllkcWs},
     {owner=[e-mail], id=CjOqUVTRRMnU2Y0ZJYms},
     {owner=[e-mail], id=CjOqUXzBmeE1CT0VLNkE}, 
     {owner=[e-mail], id=CjfKj4ur7YcttORkXTn8D2rvGE},
     {owner=[e-mail], id=CjOqUY3RFUFlScDBlclk}
    ]

Next函数，我需要通过这个数组是batchPermissionChange将批量文件的所有权改为我的服务帐户。但是我想它运行每个用户batchPermissionChange。因此，如果如[e-mail]有4个文件，我不想batchPermissionChange功能被触发4次，我想它与[e-mail]触发它一次，包括他的四个FILEID的。

Next function that i need to pass this array to is batchPermissionChange which will batch change the ownership to my service account. However i would like it to run batchPermissionChange per user. So if e.g [e-mail] have 4 files, i don't want the batchPermissionChange function to be triggered 4 times, i would like it to trigger it one time with [e-mail], and include his four fileID's.

function batchPermissionChange(ownerEmail, filesArray){
Do batch job Google... https://www.googleapis.com/batch
}

问

我如何运行功能batchPermissionChange（OWNEREMAIL，filesArray）与例如[e-mail]与他的4 FILEID的？我可以遍历数组一样，'在阵列中的每个项目上运行batchPermissionChange，但将触发批量功能的4倍，为用户[e-mail]。

How do i run the function batchPermissionChange(ownerEmail, filesArray) with for e.g [e-mail] with his 4 fileId's? I could loop through the array, like, 'for each item in array run batchPermissionChange', but that will trigger the batch-function 4 times for the user [e-mail].

推荐答案

在检索文件的列表，而不是推的所有文件到一个单一的阵列，可以创建地图阵列，与地图的钥匙作为业主，以及阵列是文件列表中为所有者。

When you retrieve the list of files, instead of pushing all the files into a single array, you can create a map of arrays, with the keys in the map being the owners, and the arrays being the list of files for that owner.

function getDriveFiles(folder, path) {
  var folder = DriveApp.getFolderById("0B23heXhtbThYaWdxzMc");
  var path = "";
  var files = {};
  var fileIt = folder.getFiles();
  while (fileIt.hasNext()) {
    var f = fileIt.next();
    var owner = f.getOwner().getEmail();
    var id = f.getId();

    if (owner != "[e-mail]") {
      // if the owner doesn't exist yet, add an empty array
      if (!files[owner]) {
        files[owner] = [];
      }

      // push the file to the owner's array
      files[owner].push(id);
    }
  }
  return files;
}

的文件对象最终会看起来像这样：

The files object will end up looking something like this:

{
  '[e-mail]': ['CjOqUeno3Yjd4VEFrYzg', 'CjOqUYWxWaVpTQ2tKc3c', 'CjOqUNTltdHo2NllkcWs', 'CjOqUVTRRMnU2Y0ZJYms'],
  '[e-mail]': ['CjOqUXzBmeE1CT0VLNkE'],
  '[e-mail]': ['CjfKj4ur7YcttORkXTn8D2rvGE', 'CjOqUY3RFUFlScDBlclk']
}

现在，在您要拨打 batchPermissionChange 您code的地区，像这样做：

Now, in the area of your code where you want to call batchPermissionChange, do it like this:

for(var ownerEmail in files) {
  if(files.hasOwnProperty(ownerEmail)) {
    // NOTE: I'm not sure what the first parameter should be for this, but 
    // this shows how to send the array of files for just one user at a 
    // time, so change the first parameter if I got it wrong.
    batchPermissionChange(ownerEmail, files[ownerEmail]);
  }
}
