How is OAuth used in web server applications?
See how. This document explains how web server applications use Google API Client Libraries or Google OAuth 2.0 endpoints to implement OAuth 2.0 authorization to access Google APIs. OAuth 2.0 allows users to share specific data with an application while keeping their usernames, passwords, and other information private.
What are the redirect URIs for OAuth 2.0?
The redirect URIs are the endpoints to which the OAuth 2.0 server can send responses. These endpoints must adhere to Google’s validation rules . For testing, you can specify URIs that refer to the local machine, such as http://localhost:8080.
When to use Google API client library for OAuth?
When you use a Google API Client Library to handle your application’s OAuth 2.0 flow, the client library performs many actions that the application would otherwise need to handle on its own. For example, it determines when the application can use or refresh stored access tokens as well as when the application must reacquire consent.
How to create OAuth client ID in Java?
Click Create credentials > OAuth client ID. Select the Web application application type. Fill in the form and click Create. Applications that use languages and frameworks like PHP, Java, Python, Ruby, and .NET must specify authorized redirect URIs.
How to use OAuth for offline access?
For example, this code requests read-only, offline access to a user’s Google Drive: // your app can refresh the access token without user interaction. // Using “consent” ensures that your application always receives a refresh token. // If you are not using offline access, you can omit this.
How to obtain an OAuth 2.0 access token?
Obtaining OAuth 2.0 access tokens. Step 1: Set authorization parameters. Step 2: Redirect to Google’s OAuth 2.0 server. Step 3: Google prompts user for consent. Step 4: Handle the OAuth 2.0 server response.
How to use OAuth 2.0 in Google client?
If you use a Google client library for OAuth 2.0 authentication and authorization, you create and configure an object that defines these parameters. If you call the Google OAuth 2.0 endpoint directly, you’ll generate a URL and set the parameters on that URL.
