This paper delves into the historical changes and technical evolution of the Facebook sharer (sharer.php) URL parameter passing mechanism. Initially, developers could pass custom content such as title, summary, and images directly via URL parameters, but Facebook updated its sharing plugin behavior around 2015, discontinuing support for custom parameters and mandating reliance on Open Graph (OG) meta tags to automatically fetch information from target pages. Through analysis of official documentation and developer feedback, the article explains the technical background, implementation principles, and impact on development practices. The core conclusion is that modern Facebook sharing should be entirely based on OG meta tags (e.g., og:title, og:description, og:image) configured via the Facebook Debugger tool to ensure consistency and controllability of shared content. The paper also briefly reviews legacy parameter passing methods (e.g., the quote parameter) and their limitations, providing comprehensive technical reference for developers.
