如何在Meteor客户端中加载JSON文件或如何在服务器端更改Meteor.settings以供客户端使用

问题描述

我正在运行Meteor 0.7.2，并希望在客户端加载JSON文件.我在应用程序根目录的/private文件夹中放置了一个JSON文件，并使用以下代码将其正确地加载到服务器端:

I am running Meteor 0.7.2 and want to load a JSON file in the client side. I have placed a JSON file in /private folder in the app root directory and it is loaded in server side without errors using following code:

var jsonData = JSON.parse(Assets.getText("myjson.json"));

但是我也想在客户端做同样的事情.在客户端加载应用程序后，我想在客户端加载JSON文件.或者，如果无法加载JSoN，那么我想在服务器端更新/分配Meteor.settings.pulbic中的值，并且该更新需要客户端使用. (我阅读了Meteor文档，并参考了其他一些资源，但找不到解决方法.)

But I want to do the same thing in client side too. When the app is loaded in client side, I want to load a JSON file at client side. Or if that JSoN loading is not possible then I want to update/assign value in Meteor.settings.pulbic in the server side and that update needs to be available to clients. (I read the Meteor documentation and refer several other resources, but couldn't figure out a way to do that.)

有人对以下事情有想法吗?

Can anybody have an idea on following things?

• 要在客户端放置要加载的文件的位置(类似于服务器的/private文件夹)
• 应该使用哪种方法读取该文件(如果有JSON可以存储的地方)
• 或者有一种方法可以在服务器端Meteor.settings.public加载后可供clents更新

• Where to place a file to be loaded in client side (same like /private folder for server)
• What method should used to read that file (if there is a place for a JSON to store)
• Or is there a way to update Meteor.settings.public from server side when it is loaded and available to clents

推荐答案

如果要使文件在客户端上可访问，请将其放在/public中.

If you want to make files accessible on the client, put it in /public.

例如，如果您创建文件/public/foo.json，则可以在//server:port/foo.json上访问该文件.您可以使用任何标准的HTTP和AJAX方法(包括Meteor的内置 HTTP.get )加载该文件.

For example, if you create a file /public/foo.json, it will be accessible at //server:port/foo.json. You can load this file using any standard HTTP and AJAX methods, including Meteor's built-in HTTP.get.
