使用 Meteor 生成和提供静态文件 [英] generating and serving static files with Meteor

问题描述

我希望根据提供的对象的内容创建静态文本文件，然后用户可以下载这些文件.这是我打算做的:

I'm looking to create static text files based upon the content of a supplied object, which can then be downloaded by the user. Here's what I was planning on doing:

1. 当用户点击导出"时，应用程序调用 Meteor.method()，然后使用典型的 Node 方法解析文件并将其写入公共目录.

1. When the user hits 'export' the application calls a Meteor.method() which, in turn, parses and writes the file to the public directory using typical Node methods.

创建文件后，在来自 Meteor.method() 的回调中，我提供了一个指向生成文件的链接.例如，'public/userId/file.txt'.然后，用户可以选择从该链接下载文件.

Once the file is created, in the callback from Meteor.method() I provide a link to the generated file. For example, 'public/userId/file.txt'. The user can then choose to download the file at that link.

然后我使用 Meteor 的 Connect modele(它在内部使用)将任何对上述 URL 的请求路由到文件本身.我可以根据 userId 和用户的登录状态进行一些权限检查.

I then use Meteor's Connect modele (which it uses internally) to route any requests to the above URL to the file itself. I could do some permissions checking based on the userId and the logged in state of the user.

问题:公开生成静态文件时，网页每次都会自动重新加载.我认为使用 Express 之类的东西来生成 REST 端点可能更有意义，它可以处理创建文件.但是如果我无权访问 Meteor 会话数据，我不确定如何处理权限.

The problem: When static files are generated in public, the web page automatically reloads each time. I thought that it might make more sense to use something like Express to generate a REST endpoint, which could deal with creating the files. But then I'm not sure how to deal with permissions if I don't have access to the Meteor session data.

对这里的最佳策略有什么想法吗?

Any ideas on the best strategy here?

推荐答案

Symlink hack 将不再适用于 Meteor(从 0.6.5 开始).相反，我建议使用与以下类似的代码创建一个包:

The symlink hack will no longer work in Meteor (from 0.6.5). Instead I suggest creating a package with similar code to the following:

packge.js

Package.describe({
  summary: "Application file server."
});

Npm.depends({
  connect: "2.7.10"
});

Package.on_use(function(api) {
  api.use(['webapp', 'routepolicy'], 'server');

  api.add_files([
    'app-file-server.js',
  ], 'server'); 
});

app-file-server.js

var connect = Npm.require('connect');

RoutePolicy.declare('/my-uploaded-content', 'network');

// Listen to incoming http requests
WebApp.connectHandlers
  .use('/my-uploaded-content', connect.static(process.env['APP_DYN_CONTENT_DIR']));
