访问不属于我的 Google 个共享云端硬盘中的文件
Access files in Google Shared Drive not owned by me
我正在尝试使用 Google 驱动器中的 Apps 脚本来搜索公司共享驱动器中的图像文件。文件列表保存在电子表格中，脚本搜索并复制文件（如果它已经是 jpg 或 png 文件）或导出 png 文件（如果它是 google 绘图。
这是我目前的代码...
function load_list_of_images(course_workbook) {
var image_list_sheet = course_workbook.getSheetByName("image_list");
// Get list of image names from spreadsheet
var list_of_images = [];
var images = image_list_sheet.getRange(1,1,1000).getValues();
for (var row in images) {
for (var col in images[row]) {
var image = images[row][col];
if (image == "") {
return(list_of_images);
}
list_of_images.push(image);
}
}
}
function download_google_images() {
var course_workbook_name = "NAME"; // Title of spreadsheet with file list
var dst_folder_id = "FOLDER_ID"; // ID of destination folder
// There may be more than one!
var course_workbooks = DriveApp.getFilesByName(course_workbook_name);
// Try to access the spreadsheet
try{
var course_workbook_id = course_workbooks.next();
Logger.log("Spreadsheet ID : " + course_workbook_id);
} catch(error) {
Logger.log("Spreadsheet doesn't exist... exiting...");
return(null);
}
var course_workbook = SpreadsheetApp.open(course_workbook_id);
var list = load_list_of_images(course_workbook);
// This will hold a list of missing images
var missing = [];
// What if the list is empty?
if (list == null){
Logger.log("Errr... no images to find - check the sheet!");
return(null);
}
// Set up handle to destination folder
var dst_folder = DriveApp.getFolderById(dst_folder_id);
// Now look for each image in the list
for (var row in list){
// Get the name of the image to look for
var image_name = list[row];
Logger.log("Looking for : " + image_name);
// Get all the files which match this name
// This line ONLY finds images that are owned by me
// MOST of the images are owned by other users
var image_exists = DriveApp.getFilesByName(image_name);
// The list of images is empty
if (!image_exists.hasNext()){
Logger.log(" Can't find image : " + image_name);
missing.push([image_name]);
}
// I found some images!
else{
while (image_exists.hasNext()){
var image = image_exists.next()
var drive_mime_type = image.getMimeType();
// I'll tell you which type of file I've found
Logger.log(" I've found a '" + drive_mime_type + "' file.");
// Deal with file types
switch (drive_mime_type) {
// Existing JPG file
case "image/jpeg":
var already_exists = DriveApp.getFolderById(dst_folder_id).getFilesByName(image_name);
if (!already_exists.hasNext()){
Logger.log(" Creating image : " + image_name);
var copy = image.makeCopy(dst_folder);
}
else{
Logger.log(" It's already in the destination so I won't create another one.");
}
break;
// Existing PNG file
case "image/png":
var already_exists = DriveApp.getFolderById(dst_folder_id).getFilesByName(image_name);
if (!already_exists.hasNext()){
Logger.log(" Creating image : " + image_name);
var copy = image.makeCopy(dst_folder);
}
else{
Logger.log(" It's already in the destination so I won't create another one.");
}
break;
// Google drawing - Convert to PNG!
case "application/vnd.google-apps.drawing":
var exportUrl = "https://www.googleapis.com/drive/v3/files/" + image.getId() + "/export?mimeType=image/png";
var urlFetchOptions = {
headers: {Authorization : "Bearer " + ScriptApp.getOAuthToken()}
}
try{
var blob = UrlFetchApp.fetch(exportUrl, urlFetchOptions).getBlob();
}
catch(err){
Logger.log(" There is an error getting the image : " + image_name);
Logger.log(err);
return(null);
}
var already_exists = DriveApp.getFolderById(dst_folder_id).getFilesByName(image_name + ".png");
if (!already_exists.hasNext()){
Logger.log(" Creating image : " + image_name);
DriveApp.getFolderById(dst_folder_id).createFile(blob).setName(image_name + ".png");
}
else {
Logger.log(" There is already a png version in the destination so I won't create another one.");
}
break;
}
}
}
}
// Populate the missing images list
var missing_images_sheet = course_workbook.getSheetByName("missing_images");
missing_images_sheet.getRange(1,1,1000).clear();
var missing_images_range = missing_images_sheet.getRange(1,1,missing.length);
missing_images_range.setValues(missing);
}
所有图像文件都在共享 Google 驱动器中。我是所有驱动器的正式成员。目前的行为是只有 我拥有的文件 从共享驱动器中找到并复制到目标文件夹中，而大多数图像是由驱动器的另一个用户创建的。
如何更改脚本以便它找到任何人拥有的文件？
带有脚本的 appscript.json 文件如下所示...
{
"timeZone": "Europe/London",
"dependencies": {
"enabledAdvancedServices": []
},
"oauthScopes": [
"https://www.googleapis.com/auth/drive.readonly",

感谢您的帮助！
在那种情况下，使用 Drive API 代替 Drive 服务怎么样？当你的脚本修改后，变成如下。
主要修改如下
发件人：
var image_exists = DriveApp.getFilesByName(image_name);
收件人：
var image_exists = Drive.Files.list({corpora: "drive", driveId: "###DriveID###", includeItemsFromAllDrives: true, supportsAllDrives: true, maxResults: 1000, q: `title='${image_name}'`}).items;
修改后的脚本：
这种情况下，请修改download_google_images()如下。请将共享驱动器的驱动器 ID 设置为 ###DriveID### of var image_exists = Drive.Files.list({corpora: "drive", driveId: "###DriveID###", includeItemsFromAllDrives: true, supportsAllDrives: true, maxResults: 1000, q: title='${image_name}'}).items;。还有 please enable Drive API at Advanced Google services.

missing_images_sheet.getRange(1,1,1000).clear();

missing_images_range.setValues(missing);
}
注：
- 在这种情况下，当您没有reader的权限或共享驱动器的编写者时，将无法使用上述修改后的脚本。所以请注意这一点。
- 在当前阶段，似乎无法使用
DriveApp.getFilesByName(filename) 和文件名来检索共享云端硬盘中的文件。另一方面，当使用文件 ID 时，DriveApp.getFileById(fileId) returns 来自共享驱动器的文件对象。基于这种情况，我建议使用files.list in Drive API 的方法从文件名中检索文件元数据。这是来自 .
