创建一个与上传文件的文件夹同名的文件
[英]Create a file with the same name as the folder where a file was uploaded
问题描述
我在 Web 应用程序中有一个 HTML 表单，是使用 GAS 创建的。
此 HTML 表单是根据此处的文件上传脚本创建的：
这是 HTML 表格：
关键是我需要将文件上传到遵循以下模式的文件夹中：
第一个数字是指在表格上选择的 model ，第二个数字是指使用的插槽。
因此需要创建一个function来识别Model中选择的input ，根据这个input判断第一个空文件夹是哪个，然后取那个文件夹的ID传给客户端上传文件在里面。
在社区一些成员的帮助下，进行了一些改编，最终的 function 是这样的：
/** Modified version of script written by Tanaike */
function createOrGetFolder(folderName, parentFolderId) {
try {
var parentFolder = DriveApp.getFolderById(parentFolderId), folder;
if (parentFolder) {
var foldersIter = parentFolder.getFoldersByName("Video");
if (foldersIter.hasNext()) {
var videoFolder = foldersIter.next();
var nextFolderName = folderName + "-01";
while (!folder) {
video_folder = videoFolder.getFoldersByName(nextFolderName);
if (video_folder.hasNext()) {
folder = video_folder.next();
var files = folder.getFiles();
if (files.hasNext()) {
var [a, b] = nextFolderName.split("-");
nextFolderName = `${a}-${String(Number(b) + 1).padStart(2, "0")}`;
folder = null;
}
} else {
folder = videoFolder.createFolder(nextFolderName);
}
}
} else {
folder = parentFolder.createFolder("Video");
folder = folder.createFolder(folderName);
}
} else {
throw new Error("Parent Folder with id: " + parentFolderId + " not found");
}
return folder.getId();
} catch (error) {
return error;
}
}
它工作得很好，关键是这个表单还有一个 function，在提交表单时生成一个.csv 文件，function 是这个：
.gs文件：
const saveDataAsCSV = (data, folderId) => DriveApp.getFolderById(folderId).createFile("Sample.csv", data);
HTML档案：
var name = $('#name01').val();
var description = $('#description').val();
var model = $('#Model').val();
upload_folder = model;
var color = $('#Color').val();
var form_values = [name, description, model, color];
var data = form_values.join(",");
google.script.run.saveDataAsCSV(data, uploadParentFolderId);
我的目标是使 .csv 文件生成与上传文件的文件夹同名，也就是说，如果文件上传到文件夹01-01 ，文件名必须是01-01.csv ，如果文件上传到02-02文件夹，文件名必须是02-02.csv ，依此类推。
我怎样才能做到这一点？
完整的脚本代码可以在这里查看：
.gs文件：
function doGet(e) {
return HtmlService.createTemplateFromFile('forms0101.html').evaluate();
}
function getOAuthToken() {
return ScriptApp.getOAuthToken();
}
function getParent(){
var ss = SpreadsheetApp.getActiveSpreadsheet();
var id = ss.getId();
var parent = DriveApp.getFileById(id).getParents().next().getId();
return parent
}
function getLimitFolder(){
var ss = SpreadsheetApp.getActiveSpreadsheet();
var pastapai = DriveApp.getFileById(ss.getId()).getParents();
var limitfolder = pastapai.next().getFoldersByName("_").next().getId();
return limitfolder;
}
function getFilesLimit(){
var ss = SpreadsheetApp.getActiveSpreadsheet();
var pastapai = DriveApp.getFileById(ss.getId()).getParents();
var files = [];
Logger.log(pastapai);
//var limitfolder = pastapai.next().getFoldersByName("_").next().getId();
var limitfolder = pastapai.next().getFoldersByName("_").next().getFiles();
while(limitfolder.hasNext()){
var file = limitfolder.next();
files.push([file.getId()]);
}
console.log(files.length);
return files.length;
}
//function testenumeroarquivos(){
//console.log(checkForFiles()); // When you use this line, you can see the filename of the files.
//}
/**
* creates a folder under a parent folder, and returns it's id. If the folder already exists
* then it is not created and it simply returns the id of the existing one
*/
function createOrGetFolder(folderName, parentFolderId) {
try {
var parentFolder = DriveApp.getFolderById(parentFolderId), folder;
if (parentFolder) {
var foldersIter = parentFolder.getFoldersByName("Video");
if (foldersIter.hasNext()) {
var videoFolder = foldersIter.next();
var nextFolderName = folderName + "-01";
while (!folder) {
video_folder = videoFolder.getFoldersByName(nextFolderName);
if (video_folder.hasNext()) {
folder = video_folder.next();
var files = folder.getFiles();
if (files.hasNext()) {
var [a, b] = nextFolderName.split("-");
nextFolderName = `${a}-${String(Number(b) + 1).padStart(2, "0")}`;
folder = null;
}
} else {
folder = videoFolder.createFolder(nextFolderName);
}
}
} else {
folder = parentFolder.createFolder("Video");
folder = folder.createFolder(folderName);
}
} else {
throw new Error("Parent Folder with id: " + parentFolderId + " not found");
}
console.log("Test" + nextFolderName)
return folder.getId();
} catch (error) {
return error;
}
}
const saveDataAsCSV = (data, folderId) => {
const folder = DriveApp.getFolderById(folderId);
folder.createFile(`${nextFolderName.getName()}.csv`, data);
}
const increaseRequest = (data, folderId) => DriveApp.getFolderById(folderId).createFile("IncreaseRequest.csv", data);
// NOTE: always make sure we use DriveApp, even if it's in a comment, for google to import those
// libraries and allow the rest of the app to work. see https://github.com/tanaikech/Resumable_Upload_For_WebApps

虽然我不确定我是否能正确理解你的实际预期结果，但请测试以下修改。
Google Apps 脚本端：
请修改 Google Apps Script 的saveDataAsCSV如下。
const saveDataAsCSV = (data, folderId1, folderId2 = null) => {
if (folderId2) {
DriveApp.getFolderById(folderId1).createFile(`${DriveApp.getFolderById(folderId2).getName()}.csv`, data);
} else {
DriveApp.getFolderById(folderId1).createFile("sample.csv", data);
}
}
Javascript 方：
请删除google.script.run.saveDataAsCSV(data, uploadParentFolderId); 在 function submitForm中。
并且，修改onFileReaderLoad的onFileReaderLoad如下。
function onFileReaderLoad(onLoadEvent) {
var fr = this;
var newFolderName = upload_folder
createOrGetFolder(newFolderName, uploadParentFolderId).then(newFolderId => {
google.script.run.saveDataAsCSV(data, uploadParentFolderId, newFolderId);
console.log("Found or created guest folder with id: ", newFolderId);
uploadFileToDriveFolder.call(fr, newFolderId).then(() => {
fr.resolve();
}, (error) => {
fr.reject(error);
});
},
(error) => {
if (error) {
showError(error.toString());
}
console.log("onFileReaderLoad Error2: ", error);
});
}
- 通过此修改，我认为创建了一个 CSV 文件，如
01-01.csv到uploadParentFolderId文件夹。
