This article provides an in-depth exploration of the distinctions and relationships between JWT (JSON Web Token) and Bearer Token in authorization mechanisms. JWT serves as a self-contained token encoding standard that encapsulates claim information in JSON format with support for signature verification, while Bearer Token defines a transmission paradigm for authorization credentials in HTTP requests. The analysis systematically examines technical specifications, application scenarios, and architectural advantages, clarifying that JWT can function as a concrete implementation of Bearer Token, with detailed explanations of its practical applications in modern authorization frameworks like OAuth 2.0.

This paper provides an in-depth exploration of technical methods for obtaining user IDs in Facebook desktop applications via the Graph API. It begins by outlining the OAuth 2.0 authorization flow, including redirection to the authorization endpoint, acquisition of authorization codes, and exchange for access tokens.
