node.js - 在 node.js restify 中限制每个 url

Question

文档指出:

Note that you can always place this on per-URL routes to enable different request rates to different resources (if for example, one route, like /my/slow/database is much easier to overwhlem than /my/fast/memcache).

我很难找到如何准确地实现它。

基本上，我想以与我的 API 不同的节流率提供静态文件。

像这样为某些端点设置限制(速率限制器)和 restify。

    var rateLimit = restify.throttle({burst:100,rate:50,ip:true});
    server.get('/my/endpoint',
        rateLimit,
        function(req, res, next) {
            // Do something here
            return next();
        }
    );
    server.post('/another/endpoint',
        rateLimit,
        function(req, res, next) {
            // Do something here
            return next();
        }
    );

或者像这样。

    server.post('/my/endpoint',
        restify.throttle({burst:100,rate:50,ip:true}),
        function(req, res, next) {
            // Do something here
            return next();
        }
    );

即使在每个端点进行节流时，仍然可能需要全局节流，因此可以像这样完成。

    server.use(restify.throttle({burst:100,rate:50,ip:true});
