Question

我是Python新手。我想使用Google文本转语音API，因为我使用了以下代码，但由于错误，我无法访问API。这是代码，

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

    input_text = texttospeech.types.SynthesisInput(text=text)

    # 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"')

这是错误，

google.auth.exceptions.DefaultCredentialsError: Could not automatically determine credentials. Please set GOOGLE_APPLICATION_CREDENTIALS or
explicitly create credential and re-run the application. For more
information, please see
https://developers.google.com/accounts/docs/application-default-credentials.

我已经拥有凭据JSON文件，但我无法配置代码来验证我的请求。请帮忙！

Answer 1

您可以尝试以下代码：

public class MyFragmentPagerAdapter extends FragmentStatePagerAdapter {

    @Override
    public Fragment getItem (int position){
        switch (position) {
            case 0:
                //
            case 1:
                //
            case 2:
                return new MyFragment();
        }
        return null;
    }

    @Override
    public int getCount() {
        return 3;
    }

    @Override
    public int getItemPosition(Object object) {
        return POSITION_NONE;
    }

}

Answer 2

您可以通过不同方式验证您的Google凭据。一种是通过设置OS环境而另一种是在您发起请求时进行身份验证。

我建议oauth2client库让python进行身份验证。除此之外，请参阅我在Github上的例子（Link）。

Answer 3

有2种方法：

1种方式：如果您使用Json文件，则最好将json路径设置为环境变量，如果您这样做，则无需进行编码设置，它将自动从那里获取许可证

GOOGLE_APPLICATION_CREDENTIALS=[path]

2路：

我有我不了解python的Java代码，因此您可以从这里获得想法：

String jsonPath = "file.json"; 
 CredentialsProvider credentialsProvider = FixedCredentialsProvider.create(ServiceAccountCredentials.fromStream(new FileInputStream(jsonPath)));
TextToSpeechSettings settings = TextToSpeechSettings.newBuilder().setCredentialsProvider(credentialsProvider).build();
    Instantiates a client
TextToSpeechClient textToSpeechClient = TextToSpeechClient.create(settings)

Answer 4

这似乎是一个古老的讨论，但我想发表评论，也许有人会遇到像我这样的情况:)）对于 nodejs 客户端，我设法通过这种方式对其进行了身份验证：

const client = new textToSpeech.TextToSpeechClient({
credentials: {
private_key: "??",
client_email: "???",
 }
});

如何将凭据添加到Google文本到语音API？
