我可以从CLI下载IBM Watson令牌并将其保存为文件 token

curl -X GET --user username:password --output token
"https://stream.watsonplatform.net/authorization/api/v1/token?url=https://stream.watsonplatform.net/speech-to-text/api"

如何在Node中执行此操作?我最好的猜测是:

var http = require('http');
var fs = require('fs');

var username = 'groucho';
var password = 'swordfish';

var header = { 
    // where does https go?
    Host: 'stream.watsonplatform.net',
    Path: '/authorization/api/v1/token?url=https://stream.watsonplatform.net/speech-to-text/api',
    Authorization: username:password
  };

var download = function(header, dest, cb) {
  var file = fs.createWriteStream("/javascript/services/token");
  var request = http.get(header, function(response) {
    response.pipe(file);
    file.on('finish', function() {
      file.close(cb);  // close() is async, call cb after close completes.
    });
  }).on('error', function(err) { // Handle errors
    fs.unlink(dest); // Delete the file async. (But we don't check the result)
    if (cb) cb(err.message);
  });

问题是服务器 https http

watson developer cloud package for speech to text 下面是一个使用该软件包的简单示例。这个例子直接来自文档

var SpeechToTextV1 = require('watson-developer-cloud/speech-to-text/v1');
var fs = require('fs');

var speech_to_text = new SpeechToTextV1({
  username: '<username>',
  password: '<password>'
});

var params = {
  // From file
  audio: fs.createReadStream('./resources/speech.wav'),
  content_type: 'audio/l16; rate=44100'
};

speech_to_text.recognize(params, function(err, res) {
  if (err)
    console.log(err);
  else
    console.log(JSON.stringify(res, null, 2));
});

// or streaming
fs.createReadStream('./resources/speech.wav')
  .pipe(speech_to_text.createRecognizeStream({ content_type: 'audio/l16; rate=44100' }))
  .pipe(fs.createWriteStream('./transcription.txt'));

request package

var request = require('request');
var username = 'username',
    password = 'password',
    url = 'https://' + username + ':' + password + '@stream.watsonplatform.net/authorization/api/v1/token?url=https://stream.watsonplatform.net/speech-to-text/api';

request({url: url}, function (error, response, body) {
   // Do more stuff with 'body' here
});

打电话怎么样 curl

const
    URL = "https://stream.watsonplatform.net/authorization/api/v1/token?url=https://stream.watsonplatform.net/speech-to-text/api",
    curlCommand = `curl -X GET --user username:password --output token ${URL}`,
    {
        exec
    } = require('child_process');

exec(curlCommand, (err, stdout, stderr) => {
            // your callback
});
