SAML redirect for Google Workspace™ by Devoteam G Cloud

This repository contains a Node.js application designed to be deployed as a Google Cloud Run service. It provides a dynamic HTTP redirect based on a query parameter that will skip the payload that prevent proper redirection from some website.

Functionality

The service listens for HTTP GET or POST requests. It expects a query parameter named targetUrl.

• If targetUrl is provided and valid (starts with http:// or https://): The service responds with an HTTP 302 Found redirect to the specified URL.
• If targetUrl is missing, empty, or invalid: The service responds with an HTTP 400 Bad Request error.

Usage

Once deployed, you can use the service URL like this:

https://<your-cloud-run-service-url>/?targetUrl=https://www.google.com

Replace <your-cloud-run-service-url> with the actual URL provided by Cloud Run after deployment. Replace https://www.google.com with the desired destination URL.

Example:

Accessing https://my-redirector-xyz.a.run.app/?targetUrl=https://developer.mozilla.org will redirect your browser to https://developer.mozilla.org.

Accessing https://my-redirector-xyz.a.run.app/ (without the parameter) will result in a "Bad Request" error page.

Deployment to Cloud Run

You can deploy this service directly to Google Cloud Run using the button below:
