What is the format of a folder ID in Google Drive? - google-api

My question is similar to What is format of Google Drive's FileID ? I need to find out whether new File has been uploaded to my drive or not using API's but I want to know the format of a folder ID in Google Drive, the one that appears in the URL bar when you open a folder in your Google drive, the thing after https://drive.google.com/drive/u/0/folders/<this part>.

Google Drive folder id doesn't have a specific guaranteed format. This (apparent format which really isn't a format) has changed in the past and may change again.
Trying to create any kind of local verification of this will be futile.
The best option would be to do a Files: get and test if you get a response. This will work better as it will also verify that the user has access to the file as well as testing that its a valid file id format.
Any (regex) attempt to verify the file id wouldn't really verify it as its not going to test if the user has access.

A folder ID starts with a 1 followed by 32 base-64 encoded digits, except unlike base64 the + is replaced by - and / is replaced by _. You can use the following regex:
/^1[A-Za-z0-9-_]{32}$/

Download Using Google Drive API with the original filename and extension

As the Google Drive API document said about downloading a file:
https://www.googleapis.com/drive/v3/files/FILEID?alt=media%26key=API_KEY
If we paste this link to Chrome or Safari It will start downloading.
But the problem is
The name is changed to FIELDID
The extension is gone
For example
I have file mywork.fbx I upload to google drive, and the FileID is ABCDEFG
Then I go to the link below.
https://www.googleapis.com/drive/v3/files/ABCDEFG?alt=media%26key=MYAPIKEY
I got the file that name is ABCDEFG without extension
It should be mywork.fbx or anyname.fbx not just ABCDEFG
Tried
add &download="mywork.fbx"
use PHP header('Content-Disposition: attachment; filename="mywork.fbx"'); filename is mywork.fbx but the bandwidth is also mine too It's not only Google Drive!!!
$file_url = 'https://www.googleapis.com/drive/v3/files/ABCDEFG?alt=media&key=KEY';
header('Content-Disposition: attachment; filename="mywork.fbx"');
readfile($file_url);
check articles in stack overflow but I can't found the right one
You want to download a file which is not Google Docs using the browser.
You want to download a file with the filename which has the filename and extension of the original file.
You are using the API key.
In this case, the file is publicly shared.
If my understanding is correct, how about this answer? In this answer, webContentLink is used as the endpoint. The official document says as follows.
webContentLink:
A link for downloading the content of the file in a browser using cookie based authentication. In cases where the content is shared publicly, the content can be downloaded without any credentials.
Modified endpoint:
Please try to access the following endpoint with your browser.
https://drive.google.com/uc?export=download&id={fileId}
When you use this, please set the file ID. In this case, the file is not Google Docs.
When it accesses to the above endpoint, the file with the filename can be retrieved.
Reference:
Files of Drive API
If I misunderstood your question and this was not the direction, I apologize.
Look at the originalFilename property of https://developers.google.com/drive/api/v3/reference/files. You can use that in a content disposition header, see https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers/Content-Disposition

Google Drive API (REST) - Get download, files views and so on....?? (Is it possible??)

This is documentation which I'm using - https://developers.google.com/drive/api/v3/search-parameters
Does anyone know the way of getting through Google Drive API, the number of times the file was downloaded, views(ideal views by whom)...
I could not find any way of doing this.
Google drive files are denoted by a file resource this contains all the information that you have access to about the file. Only some of the information you are after is available
createdTime datetime The time at which the file was created (RFC 3339 date-time). writable
modifiedTime datetime The last time the file was modified by anyone (RFC 3339 date-time).
Note that setting modifiedTime will also update modifiedByMeTime for the user.
lastModifyingUser nested object The last user to modify the file.
You can see who last changed the file but you cant see who has seen the file or any information about how many times it was downloaded.

Google Drive API v3 : there isn't any way to get a download url for a google document?

The Google Drive API v2 to v3 migration guide says:
The exportLinks field has been removed from files. To export Google Documents, use the files.export method instead.
I don't want to export (download) the file right away. "files.export" will actually download the file. I want a link to download the file, later. This was possible in v2 by means of the exportLinks.
How can I in v3 accomplish the same? If it is not possible, why was this useful feature removed?
Besides, (similar problem to above) downloadUrl was also removed, and the suggested alternative ("files.get with ?alt=media") downloads the file instead of providing a download link. This means there is no way in v3 to get a public short lived URL for a file?
EDIT:
there is no way in v3 to get a public short lived URL for a file?
For regular files, apparently yes.
This seems to work fine (a public short lived link to the file with its right name and contents):
https://www.googleapis.com/drive/v3/files/ID?alt=media&access_token=TOKEN
For google apps files, no (not even private, as v2 exportLinks used to be).
https://www.googleapis.com/drive/v3/files/ID/exportmimeType=TYPEv&access_token=TOKEN
Similar to regular files, this URL is a short lived link to the file contents, but lacking of its right name.
BTW, I see the API is not behaving consistently: /drive/v3/files/FILEID delivers the right file name, but /drive/v3/files/FILEID/export does not.
I think the API itself should be setting the right Content-Disposition, as it is apparently doing when issuing a /drive/v3/files/FILEID call.
This file naming problem invalidates the workaround to the lack of ExportLinks in v3.
The v2 ExportLinks allowed me to link a file (which is not the same as getting its content right away). Anyone logged in and with the proper permissions was able to access it, and the link didn't needed any access_token, and it wasn't short lived. It was good and useful.
Building a link with a raw API call like /drive/v3/files/FILEID/export (with mandatory access_token) would be an close enough workaround (it is temporary and public, not the same as it was, anyway). However, the naming problem invalidates it.
In v2, regular files have a WebContentLink and google apps files have exportLinks. In v3 exportLinks are gone, and I don't see any suitable alternative to them.
Once you query for your file by id you can use the function getWebContentLink() to get the download link of the file (eg. $file->getWebContentLink() ).
I think you're placing too much emphasis on the word "method".
There is still a link to export a file, it's https://www.googleapis.com/drive/v3/files/fileIdxxxxx/export&mimeType=xxxxx/xxxxx. Make sure you URL encode the mime type.
Eg
https://www.googleapis.com/drive/v3/files/1fGBQ81haNU_nEiC5GITZD3bxT0ppL2LHg-C0ubD4Q_s/export?mimeType=text/csv&access_token=ya29.Gmo0BMvO-pVEPKsiD9j4D-NZVGE91MChRvwOcBSg3cTHt5uAClf-jFxcovQScbO2QQhwHS95eSGW1eQQcK5G1UQ6oI4BFEJJkntEBkgriZ14GbHuvpDL7LT2pKA--WiPuNoDDIuZMm5lWtlr
These links form part of the API, so the expectation is that you've written a client that sends authenticated requests, and deals with the response data. This explains why, if you simply paste the link into a browser without an access_token, it will fail. It also explains why the filename is export, ie. it isn't intended that your client would ever use a filename, but rather it should receive the data as a stream. This SO answer discusses the situation in more detail How to set name of file downloaded from browser?

How to decode and inspect an HTTP payload when it is a zip

So I'm pretty new at all this. I am trying to reverse engineer a web application.
When I submit a form, it sends a POST with a request payload that looks something similar to this:
encoding=UTF8&zip=1&size=136240&html=DwQgIg_a_whole_lot_more_gibberish_not_worth_posting
Anyways, from inspecting the captured traffic from Chrome developer tools, I noticed it is encoded and sent as a zipped up html?
How would I go about reversing this to see what the content is actually being sent to the server?
What you want to do is this:
1) Get the name of the zip file
2) Get the path of the zip file (likely the root directory or the current path the form is at)
3) Generate the URL (http://site_name.com/path/to/folder/zip_file.zip)
4) Download it using a too such as wget (typing the URL into the browser may work too)
I used this technique to download all the files that get downloaded to the OTA updates on iOS devices (used burp suit to intercept the zip file name where the server was on my computer which my iDevice was connected to).
Please note: the name of the zip file you have given does not end in .zip. this may mean it doesn't have a extension; you may have to add .zip to the file manually; or it may have another ending such as .tar, .tar.gz etc.

Get a dropbox url from the command line

I'm a windows 7 user and I want to access an object from within my public dropbox folder using the command line. How do I do that (note my skills with the command line are weak so be gentle please. This is what I'm basing my information on: DROPBOX CITE LINK
Here's the path to my drop box and what I attempted:
#the path
C:/Users/trinker/Dropbox/Public/plot.png
#the attempt to retrieve the url of plot.png
CD C:/Users/trinker/Dropbox/Public/
C:/Users/trinker/Dropbox/bin/dropbox.py puburl C:/Users/trinker/Dropbox/Public/plot.png
Note my slashes are going the opposite way you'd normally see them on a windows machine as I'm using this within another program that requires the slashes be in this direction or doubled as in \\
The goal is to retrieve the url for the dropbox object.
There is a work around pointed out to me by my friend Dason. Go to your public folder and copy the link from a file. Here's one of mine:
https://dl.dropboxusercontent.com/u/61803503/%20wordcloud.pdf
The account number is always the same for your own drop box. So the following form will allow me to share documents:
file.path("https://dl.dropboxusercontent.com/u/61803503", DOCUMENT_NAME_HERE)
I don't know exactly what you are doing but if that is the url to your dropbox share, and you just wanted to access via command line have you tried just mapping a network drive to that URL to see if it works?
