使用WebRtc的Android Webview - WebSocket已经处于CLOSING或CLOSED状态

0 人关注

我在我的web视图中注入了html和js。我想做的是让我的安卓手机支持连接到本地Node.js服务器来发送和接收音频和视频。

这是我运行的Server.js。

        const HTTPS_PORT = 8443;
    const fs = require('fs');
    const https = require('https');
    const WebSocket = require('ws');
    const WebSocketServer = WebSocket.Server;
    // Yes, TLS is required
    const serverConfig = {
      key: fs.readFileSync('key.pem'),
      cert: fs.readFileSync('cert.pem'),
    // ----------------------------------------------------------------------------------------
    // Create a server for the client html page
    const handleRequest = function(request, response) {
      // Render the single client html file for any request the HTTP server receives
      console.log('request received: ' + request.url);
      if(request.url === '/') {
        response.writeHead(200, {'Content-Type': 'text/html'});
        response.end(fs.readFileSync('client/index.html'));
      } else if(request.url === '/webrtc.js') {
        response.writeHead(200, {'Content-Type': 'application/javascript'});
        response.end(fs.readFileSync('client/webrtc.js'));
    const httpsServer = https.createServer(serverConfig, handleRequest);
    httpsServer.listen(HTTPS_PORT, '192.168.1.62');
    // ----------------------------------------------------------------------------------------
    // Create a server for handling websocket calls
    const wss = new WebSocketServer({server: httpsServer});
    wss.on('connection', function(ws) {
      ws.on('message', function(message) {
        // Broadcast any received message to all clients
        console.log('received: %s', message);
        wss.broadcast(message);
    wss.broadcast = function(data) {
      this.clients.forEach(function(client) {
        if(client.readyState === WebSocket.OPEN) {
          client.send(data);
    console.log('Server running. Visit https://localhost:' + HTTPS_PORT + ' in Firefox/Chrome.\n\n\
    Some important notes:\n\
      * Note the HTTPS; there is no HTTP -> HTTPS redirect.\n\
      * You\'ll also need to accept the invalid TLS certificate.\n\
      * Some browsers or OSs may not allow the webcam to be used by multiple pages at once. You may need to use two different browsers or machines.\n'

这是在Android的Webview上可以查看的HTML。
