google 文本到语音 api 无法找到 json 键的路径，使用 python 在 windows 上使用 anaconda

Question

我正在尝试使用 google 云 api 来使用文本到语音。为此，它需要访问我保存到

的 json 密钥

C:\keys\*****.json

并将路径设置为

set GOOGLE_APPLICATION_CREDENTIALS="C:\keys\*****.json"

当我运行示例脚本时，我收到错误消息，我无法在该路径上找到文件。

C:\Users\dsandhu\Documents\linux\googlecloud\python-docs-samples\texttospeech\testing>python sampletest.py
Traceback (most recent call last):
  File "sampletest.py", line 28, in <module>
    synthesize_text("hello world")

    'File {} was not found.'.format(filename))
google.auth.exceptions.DefaultCredentialsError: File "C:\keys\*****.json" was not found.

我正在使用 anaconda（作为管理员）和 python 在 anaconda 终端中设置变量。我也尝试在 windows cmd 中设置它（使用相同的命令设置）但没有成功。

如果你想测试它，我也会张贴凭证：

def synthesize_text(text):
    """Synthesizes speech from the input string of text."""
    from google.cloud import texttospeech
    client = texttospeech.TextToSpeechClient()

    #text = "Hello world"
    input_text = texttospeech.types.SynthesisInput(text=text)
    #input_text = texttospeech.types.SynthesisInput(text="Hellow world")

    # Note: the voice can also be specified by name.
    # Names of voices can be retrieved with client.list_voices().
    voice = texttospeech.types.VoiceSelectionParams(
        language_code='en-US',
        ssml_gender=texttospeech.enums.SsmlVoiceGender.FEMALE)

    audio_config = texttospeech.types.AudioConfig(
        audio_encoding=texttospeech.enums.AudioEncoding.MP3)

    response = client.synthesize_speech(input_text, voice, audio_config)

    # The response's audio_content is binary.
    with open('output.mp3', 'wb') as out:
        out.write(response.audio_content)
        print('Audio content written to file "output.mp3"')



synthesize_text("hello world")

Answer 1

我只需要删除引号并执行

set GOOGLE_APPLICATION_CREDENTIALS=C:\keys\******.json

它奏效了。
