带有承载令牌的IBM Cloud语音到文本SDK身份验证失败 [英] IBM Cloud Speech-to-Text SDK auth failures with bearer token

问题描述

我正在学习使用 Watson Speech JS SDK .我特别喜欢从麦克风转录，并带有其他选择.我正在使用Firebase Cloud Function生成令牌.我正在使用AngularJS，而不是JQuery.我遇到的第一个问题是

I'm learning to use the Watson Speech JS SDK. In particular I like Transcribe from Microphone, with Alternatives. I'm generating my token with a Firebase Cloud Function. I'm using AngularJS, not JQuery. The first problem I'm running into is

var stream = WatsonSpeech.SpeechToText.recognizeMicrophone(Object.assign(token, {
          objectMode: true,
          format: false,
          wordConfidence: true
}));

我收到此错误消息:

WatsonSpeechToText: missing required parameter: opts.token

(使用$scope.token或token没有区别.)

在文档:

module.exports = function recognizeMicrophone(options) {
  if (!options || !options.token) {
    throw new Error('WatsonSpeechToText: missing required parameter: opts.token');
  }

好，它正在寻找一个options对象.我使用以下代码修复了错误:

OK, it's looking for an options object. I fixed the error with this code:

const options = {
      token: $scope.token,
      objectMode: true,
      format: false,
      wordConfidence: true
};
console.log(options);
var stream = WatsonSpeech.SpeechToText.recognizeMicrophone(options);

现在我收到此错误:

WebSocket connection to 'wss://stream.watsonplatform.net/speech-to-text/api/v1/recognize?model=en-US_BroadbandModel&watson-token=[object%20Object]' failed: HTTP Authentication failed; no valid credentials available

options对象记录以下内容:

token:
  access_token: "eyJraWQiOiIyMDIwMDIyNTE4MjgiLCJhbGciOiJSUzI1NiJ9.eyJpYW1faWQiOiJp0tU2..."
  expiration: 1585332575
  expires_in: 3600
  refresh_token: "OKC8z8ebLMzZcrAt6YgInnJJn0UIx1P3NTeDvdEC3kJqIQ7Yn9J9iu6-DF..."
  scope: "ibm openid"
  token_type: "Bearer"
objectMode: true
format: false
wordConfidence: true
smart_formatting: false

令牌是一个JSON对象，其中包括access_token.这是SDK想要的吗? RecognizeStream文档没有说明是否它需要JSON令牌，或者只需要裸露的access_token.

The token is a JSON object, which includes the access_token. Is this what the SDK wants? The RecognizeStream documentation doesn't say whether it wants the JSON token or just the naked access_token.

在expiration字段中添加000表明该令牌还剩53分钟.

Adding 000 to the expiration field shows that I have 53 minutes left on this token.

我正在使用特定于我的语音转文本服务的API密钥.

I'm using the API key that's specific to my Speech-to-Text service.

还有其他建议吗?

推荐答案

版本 0.37.0 引入了重大更改:

All options parameters for all methods are coverted to be lowerCamelCase
For example: access_token is now accessToken and content-type is now contentType

这与IBM从具有用户名/密码身份验证的Cloud Foundry服务到具有IAM身份验证和api密钥的服务有关. SDK文档说:

This is related to IBM's move from Cloud Foundry services with username/password auth to Services with IAM auth and api keys. The SDK documentation says:

NOTE: The token parameter only works for CF instances of services. For RC services using IAM for authentication, the accessToken parameter must be used.

如果使用api键，options对象将如下所示:

The options object looks like this if you use an api key:

const options = {
      accessToken: $scope.token,
      objectMode: true,
      format: false,
      wordConfidence: true
};

如果忽略令牌属性，则会收到以下错误消息:

If you leave out the token property you get this error message:

WatsonSpeechToText: missing required parameter: opts.token (CF) or opts.accessToken (RC)

这意味着，如果要从Cloud Foundry(CF)获取令牌，则该属性必须为opts.token(或options.token)；但是，如果您从IAM身份验证和一个api-key(无缘无故被称为RC)获取令牌，则该属性必须为opts.accessToken(或options.accessToken).

What that means is, if you're getting your token from Cloud Foundry (CF) the property must be opts.token (or options.token); but if you're getting your token from IAM auth and an api-key, which is called RC for no reason I know of, then the property must be opts.accessToken (or options.accessToken).

令人困惑的是，演示源代码表示access_token是属性名称:

Confusing the matter, the demo source code implies that access_token is the property name:

var stream = WatsonSpeech.SpeechToText.recognizeMicrophone(Object.assign(token, {
          objectMode: true,
          format: false,
          wordConfidence: true
}));

Object.assign使用来自IBM的target令牌对象，然后在source对象中添加或替换属性和值.由于该属性是IAM令牌中的access_token，因此您会认为，由于运行了演示程序，因此access_token是该属性.但是显然，该演示是在Cloud Foundry令牌上运行的，该令牌可以使用token或access_token作为属性名称.

Object.assign is taking the target token object as it comes from IBM and then adding or replacing the properties and values in the source object. Because the property is access_token in the IAM token you'd think that, because the demo runs, access_token is the property. But apparently the demo is running on a Cloud Foundry token, which can use either token or access_token as the property name.

如果收到此错误消息:

WatsonSpeechToText: missing required parameter: opts.token (CF) or opts.accessToken (RC)

然后，您既不使用token也不使用accessToken作为属性名称.

then you're using neither token nor accessToken as the property name.

如果收到此错误消息:

WebSocket connection to 'wss://stream.watsonplatform.net/speech-to-text/api/v1/recognize?model=en-US_BroadbandModel&watson-token=[object%20Object]' failed: HTTP Authentication failed; no valid credentials available

然后您将token与使用IAM api密钥生成的令牌一起使用.否则您的令牌已过期.您可以通过将以下代码放在您的应用中来告诉您令牌还剩多少分钟，从而轻松进行检查:

then you're using token with a token generated with an IAM api-key. Or your token is expired. You can check that easily by putting this code in your app to tell you how many minutes are left on your token:

// shows time to token expiration
    var expiry = new Date($scope.token.expiration * 1000);
    var now = Date.now();
    var duration = -(now - expiry);

    function msToTime(duration) {
      var milliseconds = parseInt((duration % 1000) / 100),
      seconds = Math.floor((duration / 1000) % 60),
      minutes = Math.floor((duration / (1000 * 60)) % 60),
      hours = Math.floor((duration / (1000 * 60 * 60)) % 24);

      hours = (hours < 10) ? "0" + hours : hours;
      minutes = (minutes < 10) ? "0" + minutes : minutes;
      seconds = (seconds < 10) ? "0" + seconds : seconds;

      return "Token expires in " + minutes + ":" + seconds + " minutes:seconds";
    }
    console.log(msToTime(duration))

您可以从CLI测试令牌是否有效.首先获得一个新令牌:

You can test if your token is valid from the CLI. First get a new token:

curl -k -X POST \
  --header "Content-Type: application/x-www-form-urlencoded" \
  --header "Accept: application/json" \
  --data-urlencode "grant_type=urn:ibm:params:oauth:grant-type:apikey" \
  --data-urlencode "apikey=s00pers3cret" \
  "https://iam.cloud.ibm.com/identity/token"

然后请求语言模型:

curl -X GET "https://stream.watsonplatform.net/speech-to-text/api/v1/models?access_token=eyJraWQiO...."

我的代码中还有另一个问题.我正在更新 IBM语音到文本SDK ，但是我的代码链接到三年前在Bower上安装的旧SDK.我没有意识到当0.38.0是最新版本时我正在使用0.33.1.将此添加到您的代码以解决此问题:

I had another problem in my code. I was updating the IBM Speech-to-Text SDK but my code was linking to an old SDK I'd installed with bower three years ago. I didn't realize that I was using 0.33.1 when 0.38.0 is the latest version. Add this to your code to catch this problem:

console.log (WatsonSpeech.version);

使用旧的SDK时，我收到一条旧的错误消息，甚至没有提到新的属性名称:

With the old SDK I was getting an old error message that didn't even mention the new property name:

WatsonSpeechToText: missing required parameter: opts.token
