Node.js Express 3.x 将变量传递给 View

Question

您可以使用以下方法向 View 公开数据:app.local 和 res.locals。有人确切知道两者之间的区别是什么吗？谢谢

Answer 1

来自 express.js API 文档:

应用本地化

Application local variables are provided to all templates rendered within the application. This is useful for providing helper functions to templates, as well as app-level data.

资源本地化

Response local variables are scoped to the request, thus only available to the view(s) rendered during that request / response cycle, if any. Otherwise this API is identical to app.locals.

这意味着唯一的区别是 res.locals 仅在请求的生命周期内有效。
