fs.readFileSync() 函数无法按预期工作 [英] fs.readFileSync() function doesn't work as expected

问题描述

以下代码未按预期工作:

The following code doesn't work as expected:

var fs = require('fs');
var PeerServer = require('peer').PeerServer;

var server = PeerServer({
port: 9000,
path: '/peerjs',
ssl: {
    key: fs.readFileSync('../certificates/key.pem', 'utf8'),
    cert: fs.readFileSync('../certificates/cert.pem', 'utf8')
}
});

它返回以下错误:

以下是我的文件结构

我在 main.js

我尝试了此处发布的解决方案，但没有为我解决.

I tried the solutions posted here but it did not solve it for me.

我在这里做错了什么?

推荐答案

if (Meteor.isServer) {
    Meteor.startup(function () {
    // code to run on server at startup
    var base = process.env.PWD;
    var fs = Npm.require('fs');
    var PeerServer = require('peer').PeerServer;


    var server = PeerServer({
        port: 9000,
        path: '/peerjs',
        ssl: {
            key: fs.readFileSync(base + '/chat/certificates/key.pem', 'utf8'),
            cert: fs.readFileSync(base + '/chat/certificates/cert.pem', 'utf8')
        }
    });
});
}
