electron - 谷歌云语音在 Electron package 中不起作用

Question

当我使用npm start命令从命令提示符运行应用程序时，它运行良好。它从语音API返回结果。

我正在使用binaryServer和binaryclient将音频流传输到Google Cloud API。

当我创建用于 Electron 应用的程序包时，一切正常，但不会从语音API返回结果。

这是我的代码片段:
Package.json

{
  "name": "test",
  "version": "1.0.0",
  "description": "test Web Server",
  "main": "main.js",
  "scripts": {  
    "start": "electron main.js"
  }, 
   "devDependencies": {   
    "electron": "^1.4.12"   
  },
  "dependencies": {    
    "binaryjs": "^0.2.1",
    "connect": "^3.3.4",
    "biased-opener": "^0.2.8",
    "serve-static": "^1.9.1",
    "uaparser": "^0.0.2", 
    "@google-cloud/speech" : "^0.5.0"
  }
}

这是我的main.js

app.on('ready', function () { 
    load_app();

});

 var workerProcess = child_process.spawn('node', __dirname + '/binaryServer.js');

    workerProcess.stdout.on('data', function (data) {
        console.log('stdout: ' + data);
    });

    workerProcess.stderr.on('data', function (data) {   
        console.log('stderr: ' + data);
    });

    workerProcess.on('close', function (code) {

        console.log('child process exited with code ' + code);
    });

    processes.push(workerProcess);

function load_app () { 
    // Launches the browser window
    mainWindow = new BrowserWindow({ width: 1080, height: 1920 });
    // Load just launched server in browser window


    mainWindow.loadURL("http://localhost:" + config.port);

    if (config.devMode) {
        mainWindow.webContents.openDevTools();
    }
    else {
        mainWindow.setFullScreen(true);
    }

}

这是我的二进制服务器

var binaryServer = require('binaryjs').BinaryServer,
    https = require('http'),
    connect = require('connect'),
    serveStatic = require('serve-static');
var config = require('./config');

var server = connect()
     .use(serveStatic(__dirname));

var speech = require('@google-cloud/speech')({
    projectId: config.speech.projectId,
    keyFilename: config.speech.keyFilename
});

httpServer = https.createServer(server);
httpServer.timeout = 0;
httpServer.listen(config.port);

var binarySer = binaryServer({ server: httpServer });

console.log("server pid" + process.pid);

binarySer.on('connection', function (client) {
    console.log("new connection...");



    client.on('stream', function (stream, meta) {

        var options = {
            config: {
                encoding: 'LINEAR16',
                sampleRate: meta.sampleRate,
                languageCode: "en-IN"

            },
            singleUtterance: false,
            interimResults: true,
            verbose: true

        };
        // Create a recognize stream
        const recognizeStream = speech.createRecognizeStream(options)
           .on('error', console.error)
          .on('data', function (data) { if (stream.writable && !stream.destroyed) stream.write(data) }); // send data to client

        if (recognizeStream.writable && !recognizeStream.destroyed && stream.readable && !stream.destroyed)
            stream.pipe(recognizeStream);  // pipe audio to cloud speech

    });

    client.on('close', function () {
        console.log("Connection Closed");
    });
});

谢谢你的帮助

在这里暗中进行拍摄(对binaryServer不太熟悉，实际上这可能是问题所在)。我也不清楚音频流的实际来源:

Electron打包了自己的V8版本。当您运行npm install时，它将安装(或即时编译)以计算机上安装的V8版本(本地版本)为目标的 native 二进制文件。当您生成子进程时，它使用相同的本地版本。

但是，打包 Electron 应用程序时，它将尝试使用Electron版本的V8生成该过程，并且会出现二进制不兼容的情况。

简单地说
[您的V8版本]!= [ Electron 的V8版本]
