节点快递中的静态路由 [英] Static routing in node express

问题描述

我在Node Express中使用了一组静态路由，并且遇到一种非常奇怪的现象.

Im using a set of static routes in Node Express and are experiencing a very strange phenomenon.

设置路由，以便'/list/*'和'/setup/*'到达不同的html文件，在这些文件中使用了目录作为存储ID，例如在 url/setup/12345 页面上更新信息会将信息存储在 12345 中.

The routing is set up so that '/list/*' and '/setup/*' gets to different html-files where the directories are used kind of as storage id, for example updating info on the page url/setup/12345 would store info in 12345.

为了能够加载脚本，还存在带有正则表达式匹配/assets/的路由，以允许访问 url/setup/assets/script.js 而无需路由到具有新存储ID的 setup.html .

To be able to load scripts and such there is also route with regex matching /assets/ to allow url/setup/assets/script.js to be reached without routing to setup.html with a new storage id.

我的问题是，即使它们具有相同的功能，它也适用于 url/setup/assets/script.js ，但不适用于 url/list/assets/script.js 路由.

My problem is that this works for url/setup/assets/script.js but not for url/list/assets/script.js even though they have identical routings.

导航到 url/list/assets/script.js 会导致 list.html (不需要的行为)

Navigating to url/list/assets/script.js leads to list.html (unwanted behaviour)

导航到 url/setup/assets/script.js 会导致 script.js (有害行为)

Navigating to url/setup/assets/script.js leads to script.js (wanted behaviour)

关于'/list/*'`为什么行不通的任何想法?

Any ideas on why '/list/*'` wont work?

这是我的静态路线:

app.use(/assets/, express.static(wwwPath));

app.use('/list/*', function(req, res, next) {
    res.sendFile('list.html', { root: wwwPath });
});

app.use('/setup/*', function(req, res, next) {
    res.sendFile('setup.html', { root: wwwPath });
});

推荐答案

解决方案是使用自定义中间件.这是新路线:

The solution was to use custom middleware. Here are the new routes:

var requestParser = function(req, res, next) {
    if(req.originalUrl.indexOf('/assets/') >= 0) {
        var assetPath = path.join(wwwPath,  req.path.slice(req.url.indexOf('/assets/')));
        fs.stat(assetPath, function(error, stat){
            if(stat && stat.isFile()) {
                res.sendFile(assetPath);
            }
            else{ 
                res.status(404).send('<h1>404</h1>');
            }
        });
    }
    else {
        next();
    }
};

app.use(requestParser);

app.use('/list/*', function(req, res, next) {
    res.sendFile('schema.html', { root: wwwPath });
});

app.use('/setup/*', function(req, res, next) {
    res.sendFile('setup.html', { root: wwwPath });
});
