问题描述

我正在寻找一种专业技术来生成唯一的 URL 地址.我创建了一个 node.js 服务器，它应该向访问客户端提供这些 URL.如何提供网址?

I'm looking for a professional technique to generate unique URL addresses. I created a node.js server that should give out these URLs to accessing clients. How can I provide the URLs?

// user is connecting to www.privatebox.de

// server serves index.html with unique ID

// e.g. www.privatebox.de/8yfuzyzzm7

推荐答案

对于稳健的解决方案，我会考虑使用 node-uuid 来生成 UUID.

For a robust solution, I would consider using node-uuid to generate UUIDs.

使用 NPM 安装包:

Install the package with NPM:

npm install node-uuid

基于来自 GitHub 项目页面的示例代码:

Based on the sample code from the GitHub project page:

var uuid = require('node-uuid');

// Generate a v1 (time-based) id
var timeBasedID = uuid.v1(); // -> '6c84fb90-12c4-11e1-840d-7b25c5ee775a'

// Generate a v4 (random) id
var randomID = uuid.v4(); // -> '110ec58a-a0f2-4ac4-8393-c866d813b8d1'

var url = 'www.privatebox.de/' + randomID;  // or + timeBasedID

如果您正在寻找更短、更适合 url 的唯一 ID，那么 ShortId 可能对您来说是一个不错的选择，尽管发生碰撞的机会会更高.ShortId 将生成如下 ID:

If you're looking for a shorter, more url-friendly unique ID, then ShortId might be a decent option for you, although the chance of collisions will be higher. ShortId will generate ids like this:

ShortId.generate() -> 'PPBqWA9'

最后，我建议你看看这个SO question 用于在 javascript 中生成唯一 ID.

Finally, I suggest you look at this SO question for generating unique ids in javascript.
