常见的想当然

On current Puppeteer, page.screenshot() returns a Node.js Buffer, so calling result.toString('base64') uses Buffer's encoding overload.

这是本样本作者记下的、开发者或模型在此处通常会有的预期。下面的契约才是真正运行过的东西。

契约

• TypeScript 5.9 accepts Puppeteer 25.7.0 page.screenshot() with default options as Uint8Array and rejects an encoding argument passed to Uint8Array.toString.
• TypeScript accepts page.screenshot({encoding: 'base64'}) as string.
• For binary screenshot bytes in Node.js, Uint8Array.toString('base64') returns comma-separated decimal bytes while Buffer.from(bytes).toString('base64') returns base64.
