如果您下载目录,Google Drive 网络界面允许您下载单个 .zip 文件。但是,我发现无法使用 API 做到这一点。是否可以使用 API 在驱动器上创建多文件 zip?
更新:Tanakie 的代码有效!这很棒!但是,我只能在我的个人帐户中使用它。我有两个 G-Suite 管理员帐户,但出现错误:
“抱歉,目前无法打开文件。
请检查地址,然后再试一次。”
我已经确认这在多个免费的个人谷歌帐户中工作正常。知道为什么它在使用付费谷歌帐户时不起作用吗?

如果您收到“抱歉,此时无法打开文件”错误,请等待一天,该错误会自行修复。
这是我仅使用 POST 的最终解决方案。就像下面 Tanaike 所说的那样。
谷歌脚本:
function doPost(e) {
var zipFileName = e.parameter.zipFileName
var fileIds = e.parameter.ids.split(",");
return ContentService.createTextOutput(zipping(fileIds, zipFileName));
}
function zipping(fileIds, zipfilename) {
var blobs = [];
var mimeInf = [];
var accesstoken = ScriptApp.getOAuthToken();
fileIds.forEach(function(fileID) {
try {
var file = DriveApp.getFileById(fileID);
var mime = file.getMimeType();
var name = file.getName();
} catch (er) {
return er
}
var blob;
if (mime == "application/vnd.google-apps.script") {
blob = UrlFetchApp.fetch("https://script.google.com/feeds/download/export?id=" + fileID + "&format=json", {
method: "GET",
headers: {"Authorization": "Bearer " + accesstoken},
muteHttpExceptions: true
}).getBlob().setName(name);
} else if (~mime.indexOf('google-apps')) {
mimeInf =
mime == "application/vnd.google-apps.spreadsheet" ? ["application/vnd.openxmlformats-officedocument.spreadsheetml.sheet", name + ".xlsx"] : mime == "application/vnd.google-apps.document" ? ["application/vnd.openxmlformats-officedocument.wordprocessingml.document", name + ".docx"] : mime == "application/vnd.google-apps.presentation" ? ["application/vnd.openxmlformats-officedocument.presentationml.presentation", name + ".pptx"] : ["application/pdf", name + ".pdf"];
blob = UrlFetchApp.fetch("https://www.googleapis.com/drive/v3/files/" + fileID + "/export?mimeType=" + mimeInf[0], {
method: "GET",
headers: {"Authorization": "Bearer " + accesstoken},
muteHttpExceptions: true
}).getBlob().setName(mimeInf[1]);
} else {
blob = UrlFetchApp.fetch("https://www.googleapis.com/drive/v3/files/" + fileID + "?alt=media", {
method: "GET",
headers: {"Authorization": "Bearer " + accesstoken},
muteHttpExceptions: true
}).getBlob().setName(name);
}
blobs.push(blob);
});
var zip = Utilities.zip(blobs, zipfilename);
var driveFolder = DriveApp.getFoldersByName("zipFiles").next();
return driveFolder.createFile(zip).getId();
}

调用它的php代码:
$url = 'https://script.google.com/a/domain.com/macros/s/### script id ####/exec';
$googleIDs = array();
foreach($documents AS $document){
$googleIDs[] = $document->google_file_id;
}
$data['zipFileName'] = date('c') . ".zip";
$data['ids'] = join(',', $googleIDs);
$ch = curl_init();
curl_setopt($ch, CURLOPT_HTTPHEADER, array( "Content-type: multipart/form-data" ));
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_POSTFIELDS, $data);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true);
$result = curl_exec($ch); // This returns the Google file ID of the zip file.
curl_close($ch);

然而,正如我在下面的评论中,这是一个无用的、徒劳的练习,因为谷歌将脚本创建的文件限制为 10M。我要去寻找一个不依赖于谷歌的解决方案......希望我在开始之前就知道这一点。
这个解决方法怎么样?
不幸的是,在 Google API 中没有用于直接从外部创建 zip 文件的 API。但我认为有一个解决方法。zip()Google Apps Script (GAS) 中有Class Utilities 的方法。还有 Web Apps 作为从外部使用 GAS 的服务。我认为你想做的事情可以通过结合它们来实现。
zip()Class Utilities 的方法创建用于创建 zip 文件的 GAS 脚本。如果这对你没有用,我很抱歉。
下面的示例脚本怎么样?这是一个简单的示例脚本,用于为文件夹中的文件创建 zip 文件。
这些与 Web 界面相同。
请执行以下流程。
function doGet(e) {
var files = DriveApp.getFolderById(e.parameter.folderid).getFiles();
var fileIds = [];
while (files.hasNext()) {
fileIds.push(files.next().getId());
}
return ContentService.createTextOutput(zipping(fileIds));
}
function zipping(fileIds) {
var zipfilename = "sample.zip";
var blobs = [];
var mimeInf = [];
var accesstoken = ScriptApp.getOAuthToken();
fileIds.forEach(function(e) {
try {
var file = DriveApp.getFileById(e);
var mime = file.getMimeType();
var name = file.getName();
} catch (er) {
return er
}
var blob;
if (mime == "application/vnd.google-apps.script") {
blob = UrlFetchApp.fetch("https://script.google.com/feeds/download/export?id=" + e + "&format=json", {
method: "GET",
headers: {"Authorization": "Bearer " + accesstoken},
muteHttpExceptions: true
}).getBlob().setName(name);
} else if (~mime.indexOf('google-apps')) {
mimeInf =
mime == "application/vnd.google-apps.spreadsheet" ? ["application/vnd.openxmlformats-officedocument.spreadsheetml.sheet", name + ".xlsx"] : mime == "application/vnd.google-apps.document" ? ["application/vnd.openxmlformats-officedocument.wordprocessingml.document", name + ".docx"] : mime == "application/vnd.google-apps.presentation" ? ["application/vnd.openxmlformats-officedocument.presentationml.presentation", name + ".pptx"] : ["application/pdf", name + ".pdf"];
blob = UrlFetchApp.fetch("https://www.googleapis.com/drive/v3/files/" + e + "/export?mimeType=" + mimeInf[0], {
method: "GET",
headers: {"Authorization": "Bearer " + accesstoken},
muteHttpExceptions: true
}).getBlob().setName(mimeInf[1]);
} else {
blob = UrlFetchApp.fetch("https://www.googleapis.com/drive/v3/files/" + e + "?alt=media", {
method: "GET",
headers: {"Authorization": "Bearer " + accesstoken},
muteHttpExceptions: true
}).getBlob().setName(name);
}
blobs.push(blob);
});
var zip = Utilities.zip(blobs, zipfilename);
return DriveApp.createFile(zip).getId();
}
