Meteor WebApp 中间件:传递参数 [英] Meteor WebApp middleware: passing params

问题描述

我想知道在使用官方webapp包监听传入的HTTP时如何传递参数在特定路由上请求.

I would like to know how to pass parameters when using the official webapp package to listen to incoming HTTP requests on a particular route.

这是一个示例代码:

WebApp.connectHandlers.use("/hello/:myParam", function(req, res, next) {
  res.writeHead(200);
  res.end("Your param is", req.myParam);
});

上述类似 Express 的示例不适用于 WebApp.经过一些实验，我现在知道我可以使用 req.query 访问查询参数.但是 WebApp 允许您访问常规参数吗?

The above Express-like example does not work with WebApp. After some experiments, I now know I can access query params using req.query. But does WebApp allow you to access regular parameters?

推荐答案

我不知道有这样的连接中间件(虽然它可能存在，在这种情况下你可以插入它)，但它很容易复制该行为:

I don't know of a connect middleware that does that (it might exist though, in which case you could plug it in), but it's easy enough to replicate that behavior:

WebApp.connectHandlers.use("/hello/", function(req, res, next) {
    var parts = req.url.split("/");
    res.writeHead(200);
    res.end("Your param is " + parts[1]);
});

不太一样，但似乎运行良好.当然，大多数人只会将 Iron-router 用于此类用途，但我假设您出于某种原因想要避免这种情况.

Not quite the same but seems to work well. Of course, most people would just use iron-router for something like this, but I'm assuming you want to avoid that for some reason.
