Google語音識別API憑據錯誤

Question

我正在嘗試集成google語音識別API，但我說說ApplicationDefaultCredentialsError出現錯誤。 我一直在搜索，但總是看到類似： set GOOGLE_APPLICATION_CREDENTIALS=[PATH] ，但我不知道在終端中實際鍵入該字符的位置以及.json文件的保存位置。 有辦法解決這個問題嗎？

import argparse
import base64
import json

from googleapiclient import discovery
import httplib2
from oauth2client.client import GoogleCredentials


DISCOVERY_URL = ('https://{api}.googleapis.com/$discovery/rest?'
                 'version={apiVersion}')


def get_speech_service():
    credentials = GoogleCredentials.get_application_default().create_scoped(
        ['https://www.googleapis.com/auth/cloud-platform'])
    http = httplib2.Http()
    credentials.authorize(http)

    return discovery.build(
        'speech', 'v1beta1', http=http, discoveryServiceUrl=DISCOVERY_URL)


def main(speech_file):
    """Transcribe the given audio file.

    Args:
        speech_file: the name of the audio file.
    """
    with open(speech_file, 'rb') as speech:
        speech_content = base64.b64encode(speech.read())

    service = get_speech_service()
    service_request = service.speech().syncrecognize(
        body={
            'config': {
                'encoding': 'LINEAR16',  # raw 16-bit signed LE samples
                'sampleRate': 16000,  # 16 khz
                'languageCode': 'en-US',  # a BCP-47 language tag
            },
            'audio': {
                'content': speech_content.decode('UTF-8')
                }
            })
    response = service_request.execute()
    print(json.dumps(response))

if __name__ == '__main__':
    parser = argparse.ArgumentParser()
    parser.add_argument(
        'speech_file', help='Full path of audio file to be recognized')
    args = parser.parse_args()
    main(args.speech_file)

您將需要將憑證導出到環境。

對於Mac-

export GOOGLE_APPLICATION_CREDENTIALS="[PATH]"

對於Windows，通過PowerShell-

$env:GOOGLE_APPLICATION_CREDENTIALS="C:\Users\username\Downloads\[FILE_NAME].json"

其中[PATH]是包含憑證的Json文件的路徑。 這是為服務器到服務器生產應用程序設置身份驗證的鏈接
