javascript - 有没有办法从 NativeScript 应用程序通过 SSL 与 WebSocket 通信？

Question

目前我正在编写一个 NS 应用程序，它将通过 SSL 与 WebSocket 进行通信。这是服务器的代码 (server.js):

var fs = require('fs');
var cfg = {
 port: 8082,
 ssl_key: fs.readFileSync('keys/server.key'),
 ssl_cert: fs.readFileSync('keys/server.crt'),
 ca: fs.readFileSync('keys/ca.crt')
};

var httpServ = require('https');

var WebSocketServer = require('ws').Server;
var app = null;

// dummy request processing
var processRequest = function( req, res ) {
    res.writeHead(200);
    res.end("All glory to WebSockets!\n");                  
};

 app = httpServ.createServer({

      // providing server with  SSL key/cert
      key: cfg.ssl_key,
      cert: cfg.ssl_cert,
      ca: cfg.ssl.ca,   
      passphrase: '1234',
      requestCert: true,
      rejectUnauthorized: false,

      }, processRequest ).listen( cfg.port );

var wss = new WebSocketServer( { server: app } );

wss.on('connection', function(ws) {
console.log("Connected!");
ws.on('message', function(message) {
console.log('received: %s', message);
});
ws.send('something');
});

服务器运行良好，没有问题。下面是客户端代码(wsclient.js):

const WebSocket = require('ws');
const ws = new WebSocket('wss://localhost:8082');
ws.on('open', function open() {
  ws.send("dummy");  
  ws.on('error', function(evt) {
      console.log("The socket had an error", evt.error);
  });
});

当我通过键入 node wsclient.js 运行客户端时，它抛出以下错误:

错误:无法验证第一个证书

很明显，错误是由于没有向请求提供证书信息造成的。但我不知道如何在我的客户端代码中完成这项工作。非常感谢任何线索或建议。

终于找到答案了:

const WebSocket = require('ws');
const ws = new WebSocket('wss://localhost:8082',{
    key: fs.readFileSync('./keys/client.key'),
    cert: fs.readFileSync('./keys/client.crt'),
    ca: fs.readFileSync('./keys/ca.crt')
});
ws.on('open', function open() {
  ws.send("dummy");  
  ws.on('error', function(evt) {
      console.log("The socket had an error", evt.error);
  });
});

现在可以了!
