通过Web应用程序在客户端上存储用户首选项的标准方式 [英] Standard Way of Storing User Preferences on Client via Web Application

问题描述

我意识到这可能不是最适合的SO，所以请告诉我应该移动/如果是这样的情况下发布。

I realize this might not be a best fit for SO, so please tell me where I should move/post this if that is the case.

我的想法是在用户登录系统后，以Cookie的形式将用户首选项存储在客户端上。如果用户修改所述首选项，请更新Cookie。我需要这样做，因为一些偏好是客户相关的，需要通过JavaScript来查看。

My idea is after a user signs into the system, store the user preferences on the client in the form of cookies. If a user modifies said preferences, update the cookies. I need to do this because some of the preferences are client related and will need to be looked at via JavaScript.

我意识到我需要存储在服务器上的首选项以及。只是想知道是否把它们下降到饼干是一个好主意。我的应用程序主要是ajax驱动，所以我想拉下一次偏好，只是存储他们。我不想为每个服务器请求推送它们。

I realize I'll need the preferences stored on the server as well. Just wanting to know if pulling them down into cookies is a good idea. My app is primarily ajax driven so I'd like to pull the preferences down once and just store them. I don't want to push them with each server request.

我想避免像本地存储这样的东西，这样我就不必担心浏览器许多。

I'd like to avoid things like Local Storage so that I don't have to worry about browsers as much. Cookies seem to be supported heavily by all browsers.

任何人都同意或有更好的方法？

Anyone concur or have a better way?

推荐答案

一般来说，cookies是一个好主意，只要你不必存储大量的数据。使用Cookie存储内容时，请记住以下几点：

Generally cookies are a good idea, provided that you don't have to store a lot of data. Just few things to keep in mind when using cookies to store stuff:

• 用户可以手动编辑偏好设置，没有额外的服务器端检查

• user can edit the preferences by hand so make sure you don't have things like is_root=false without additional server side checks.

这可以是烦人的。 is_root = false 当用户删除cookie和偏好设置后，我会去一个服务器端的偏好设置存储映射到cookies，以便JavaScript可以使用它们。

this can be annoying when user removes cookies and preferences are gone, I would go for a server side preferences storage mirrored to cookies so JavaScript can use them.

其他可能性是使用嵌入式偏好设置的动态JavaScript，而不是静态文件 - 您可以提供与提供动态HTML相同的JavaScript，但是您必须小心缓存。

Other possibility would be to serve dynamic JavaScript, with inlined preferences, instead of static files - you could serve JavaScript the same as you serve dynamic HTML, but then you have to be careful with caching.
