使用 Express 在动态路由上提供静态文件 [英] Serve Static Files on a Dynamic Route using Express

问题描述

我想像通常使用 express.static(static_path) 所做的那样提供静态文件，但是在动态路由就像通常用

I want to serve static files as is commonly done with express.static(static_path) but on a dynamic route as is commonly done with

app.get('/my/dynamic/:route', function(req, res){
    // serve stuff here
});

其中一位开发人员在此评论中暗示了解决方案，但事实并非如此立即让我明白他的意思.

A solution is hinted at in this comment by one of the developers but it isn't immediately clear to me what he means.

推荐答案

好的.我在 Express 的源代码中找到了一个示例 响应对象.这是该示例的略微修改版本.

Okay. I found an example in the source code for Express' response object. This is a slightly modified version of that example.

app.get('/user/:uid/files/*', function(req, res){
    var uid = req.params.uid,
        path = req.params[0] ? req.params[0] : 'index.html';
    res.sendFile(path, {root: './public'});
});

它使用 res.sendFile 方法.

注意:对 sendFile 的安全更改需要使用 root 选项.

NOTE: security changes to sendFile require the use of the root option.
