##Access your Google Drive files from LabVIEW
This toolkit allows users to directly upload/download files to/from their Google drive. Authentication was completed by the OAuth method documented here. This toolkit was created as a wrapper for the Google Drive .NET API that can be found online. Developers must obtain their own Client Secret JSON, found here. The Initialize VI requires this file to function, so a user must give a path to their Client Secret JSON for proper toolkit functionality. For more information on how to fill out this form, look to the bottom of this document under “Creating a client_secret.json.”
This VI will use OAuth to authenticate a user for their Google Drive Account the first time that this VI is called in LabVIEW. After that, this VI does not execute, but it is required for all functionalities of the drive, as it contains the authentication within the Drive Service Reference. Input: Path to Secret Client JSON Output: Google Drive Service Reference
Given a specific file reference, this VI will download the file to a specified local path Input: Desired file path, Google Drive Service Reference, and file reference. Output: File is downloaded to the specified path
Outputs an array that contains references to the files on a user's Google Drive. These references can be used in other VIS to access file properties and metadata Input: Google Drive Serivce Reference Output: Array of Google drive File References
Summary: Uploads a file to Google Drive Input: File Path, Google Drive Service Reference, Desired File Name on Drive Output: File specified by the path is uploaded to the Google Drive authenticated by the Google Drive Service Reference.
Lists the files on the Google Drive Input: Google Drive Service Reference Output: Array of file names, corresponding to the files on the user's Google Drive
Finds a reference to a specific file on a user's Google Drive Input: Array of file references, file name Output: File Reference
#Examples There are two examples attached that demonstrate the work flow.
Upload example: Demonstrates the steps required to take a file from your local machine and upload it to the user’s google drive.
Download example: Demonstrates the steps required to take a file from the user’s google drive and download it to your local machine.
##Creating a client_secret.json Developers can obtain their client secret json file here
- Open the wizard and press continue (make sure that the drop down selector says “create a project”)
- On the next page, click “go to credentials”
- You should now see a page titled “Add Credentials to your project”
a. Which API are you using? : Google Drive API
b. Where will you be calling the API from?: Other UI
c. What data will you be using?: User Data
d. Then, click “What credentials do I need?” - Create an OAuth 2.0 client ID
- Register your email address
- Product Name: GDrive for LabVIEW
- Download the client ID.
- Put this file in a place that you can easily access and rename this file: client_secret.json
- Use this file path in the initialize VI to authenticate your access.
- Note that the first time you run this VI, you will be prompted in a web browser to give permission for the GDrive to access your Google Drive account. Click allow and move forward in your development process.
