对云函数的Javascript请求

我试图使用Google语音到文本API，所以我试图在一个云函数（云函数API）中实现它。 问题是，我想从一个javascript文件调用该函数，该文件正在为创建语音生成订单的网站的一部分运行代码。那么我有三个问题：

·我不知道如何调用URL，同时发送函数需要的参数。我在猜一个帖子。 数据类似于：

const data = {
    audio: base64AudioFormat,
    lan: language
}

·一旦进入云计算功能，我不知道如何修改Google给定的代码，使其在这种情况下工作。 给出的代码如下：

// Imports the Google Cloud client library
const fs = require('fs');
const speech = require('@google-cloud/speech');

// Creates a client
const client = new speech.SpeechClient();

const config = {
  encoding: LINEAR16,
  sampleRateHertz: 16000,
  languageCode: (my 'lan' parameter from data),
};
const audio = {
  content: (my 'base64AudioFormat' parameter from data),
};

const request = {
  config: config,
  audio: audio,
};

// Detects speech in the audio file
const [response] = await client.recognize(request);
const transcription = response.results
  .map(result => result.alternatives[0].transcript)
  .join('\n');
console.log('Transcription: ', transcription);

·最后，我希望接收API在javascript文件中返回的字符串。我猜这是个好机会

我将感谢任何帮助

我将您的代码用于云函数。此云函数将接受数据为

{“audio”：“base64格式数据”，“lan”：“en-US”}

的请求。请求参数将放在int

req.body.audio

和

req.body.lan

中，您现在可以在代码中使用它们

为了进行测试，我在中使用了示例数据。云函数使用Node.js14

index.js:

exports.speechToText = async (req, res) => {

// Imports the Google Cloud client library
const speech = require('@google-cloud/speech');

// Creates a client
const client = new speech.SpeechClient();

const encoding = 'LINEAR16';
const sampleRateHertz = 16000;

const config = {
  encoding: encoding,
  sampleRateHertz: sampleRateHertz,
  languageCode: req.body.lan,
};

const audio = {
  content: req.body.audio,
};

const request = {
  config: config,
  audio: audio,
};

// Detects speech in the audio file
const [response] = await client.recognize(request);
const transcription = response.results
  .map(result => result.alternatives[0].transcript)
  .join('\n');
console.log('Transcription: ', transcription);

  res.status(200).send(transcription);
};

{
  "dependencies": {
    "@google-cloud/speech": "^4.5.1"
  },
  "name": "sample-http",
  "version": "0.0.1"
}

package.json:

exports.speechToText = async (req, res) => {

// Imports the Google Cloud client library
const speech = require('@google-cloud/speech');

// Creates a client
const client = new speech.SpeechClient();

const encoding = 'LINEAR16';
const sampleRateHertz = 16000;

const config = {
  encoding: encoding,
  sampleRateHertz: sampleRateHertz,
  languageCode: req.body.lan,
};

const audio = {
  content: req.body.audio,
};

const request = {
  config: config,
  audio: audio,
};

// Detects speech in the audio file
const [response] = await client.recognize(request);
const transcription = response.results
  .map(result => result.alternatives[0].transcript)
  .join('\n');
console.log('Transcription: ', transcription);

  res.status(200).send(transcription);
};

{
  "dependencies": {
    "@google-cloud/speech": "^4.5.1"
  },
  "name": "sample-http",
  "version": "0.0.1"
}

以下是我在云函数中测试代码时的请求和响应：

查看是否要查看触发函数的不同方式。

谢谢！那帮了大忙！您建议我如何从javascript请求云函数？@javierdeiosg。您可以使用javascript使用HTTP发送请求，请参见
