I am creating an application using asp.net mvc and javascript in which I want to create folders inside my existing google drive folder.
below is my code which I got from stackoverflow
function createFolder() {
var body = {
'title': document.getElementById('txtFolderName').value,
'mimeType': "application/vnd.google-apps.folder"
};
var request = gapi.client.drive.files.insert({
'resource': body
});
request.execute(function (resp) {
console.log('Folder ID: ' + resp.id);
});
}
I am getting the below error
index.html:61 Uncaught TypeError: Cannot read properties of undefined (reading 'files')
on the following line
var request = gapi.client.drive.files.insert({
here gapi.client.drive is appearing to be undefined
below is my code to authenticate and load google api client
function authenticate(callback) {
return gapi.auth2.getAuthInstance()
.signIn({ scope: "https://www.googleapis.com/auth/documents https://www.googleapis.com/auth/drive https://www.googleapis.com/auth/drive.file" })
.then(function () {
console.log("Sign-in successful");
callback == undefined ? '' : callback();
},
function (err) {
console.error("Error signing in", err);
});
}
function loadClient() {
gapi.client.setApiKey("APIKEY");
return gapi.client.load("https://docs.googleapis.com/$discovery/rest?version=v1")
.then(function () {
console.log("GAPI client loaded for API");
},
function (err) {
console.error("Error loading GAPI client for API", err);
});
}
what is the problem here?
and what I need to do if I want to create a folder inside another folder?
thanks in advance
I thought that in your script, https://docs.googleapis.com/$discovery/rest?version=v1 of gapi.client.load("https://docs.googleapis.com/$discovery/rest?version=v1") is used for Google Docs API v1. I think that the reason for your error message of Uncaught TypeError: Cannot read properties of undefined (reading 'files') is due to this.
In your goal, it seems that you want to create a folder into a specific folder. In this case, please use Drive API. But, when I saw your current script for creating the folder, Drive API v2 is used. So, please modify as follows.
return gapi.client.load("https://docs.googleapis.com/$discovery/rest?version=v1")
return gapi.client.load("https://www.googleapis.com/discovery/v1/apis/drive/v2/rest")
By this modification, I thought that your createFolder() works. But in your current createFolder(), the folder is created to the root folder. When you want to create the folder into a specific folder, please modify the request body as follows.
var body = {
'title': document.getElementById('txtFolderName').value,
'mimeType': "application/vnd.google-apps.folder",
'parents': [{'id': '###folderId###'}]
};
As additional information, if you want to use Drive API v3, please modify it as follows.
From
return gapi.client.load("https://docs.googleapis.com/$discovery/rest?version=v1")
To
return gapi.client.load("https://www.googleapis.com/discovery/v1/apis/drive/v3/rest")
And, please modify createFolder() as follows.
var body = {
'name': document.getElementById('txtFolderName').value,
'mimeType': "application/vnd.google-apps.folder",
'parents': ['###folderId###']
};
var request = gapi.client.drive.files.create({ 'resource': body });
