将文件动态插入到meteor 公共文件夹中而不隐藏它 [英] Dynamically insert files into meteor public folder without hiding it

问题描述

我有一个生成图像的流星应用程序.它们生成后，我想为它们服务.但是每次我写入公共文件夹时，我的流星服务器都会重新启动.我搜索了一个解决方案并找到了几种解决方法:

I have a meteor application that generates images. After they are generated, I want to serve them. But each time I write to the public folder, my meteor server restarts. I searched for a solution and found several workarounds:

• 在项目文件夹外提供文件 - 目前我不知道如何实现这一点，我是否必须编写某种集成到meteor中的中间件?

• Serve files outside of the project folder - At the moment I don't know how to achieve this, would I have to write some kind of middleware that integrates into meteor?

在 public/ 中的文件夹中添加一个波浪号 ~ - 这似乎让meteor 完全忽略该文件夹，当我尝试访问文件夹中的文件时，我被重定向到我的根页面.

Add a tilde ~ to the folder in public/ - which seems to make meteor ignore the folder altogether, when trying to access files in the folder I get redirected to my root page.

在生产模式下运行meteor.对我来说似乎是一个肮脏的解决方法.现在，meteor run --production 仍然会重新启动我的服务器，所以我必须捆绑我的应用程序，每次都重新安装光纤，设置我的环境变量，然后运行应用程序.每次我改变一些东西.

Run meteor in production mode. Seems like a dirty workaround for me. Right now, meteor run --production still restarts my server so I have to bundle my app, reinstall fibers every time, set my environment variables and then run the app. Every time I change something.

还有其他解决方案吗?

推荐答案

接受的答案对我不起作用，但从 0.6.6.3 版本开始，您可以执行以下操作:

The accepted answer did not work for me, but as of version 0.6.6.3 you can do the following:

var fs = Npm.require('fs');
WebApp.connectHandlers.use(function(req, res, next) {
    var re = /^/url_path/(.*)$/.exec(req.url);
    if (re !== null) {   // Only handle URLs that start with /url_path/*
        var filePath = process.env.PWD + '/.server_path/' + re[1];
        var data = fs.readFileSync(filePath, data);
        res.writeHead(200, {
                'Content-Type': 'image'
            });
        res.write(data);
        res.end();
    } else {  // Other urls will have default behaviors
        next();
    }
});

注意事项

• process.env.PWD 会给你项目根目录

• 如果您打算将文件放入项目中

  Notes

  • process.env.PWD will give you the project root

  • if you plan to put files inside your project

    • 不要使用 public 或 private 流星文件夹
    • 使用点文件夹(例如隐藏文件夹，例如:.uploads)
    • don't use the public or private meteor folders
    • use dot folders (eg. hidden folders ex: .uploads)

    不遵守这两个将导致本地流星在每次上传时重新启动，除非您使用以下命令运行流星应用程序:meteor run --production

    Not respecting these two will cause local meteor to restart on every upload, unless you run your meteor app with: meteor run --production
