Google Speech API凭据

Question

我正在尝试使用Google Speech API做一些测试，但是在Google Cloud之外。在较早的测试版中，我可以指定凭据文件，但现在我无法在SpeechClient类中找到此选项。

如何使用Google Speech API Java库指定身份验证密钥？

Answer 1

Frank答案中的一些类现在已被弃用。这是对他答案的更新。

CredentialsProvider credentialsProvider = FixedCredentialsProvider.create(ServiceAccountCredentials.fromStream(new FileInputStream("path/to/service-account.json")));

SpeechSettings settings = SpeechSettings.newBuilder().setCredentialsProvider(credentialsProvider).build();
SpeechClient speechClient = SpeechClient.create(settings);

将服务帐户传递给SpeechClient的方法是使用以下流程：

CredentialsProvider credentialsProvider = FixedCredentialsProvider.create(ServiceAccountCredentials.fromStream(new FileInputStream("/path/to/service-account.json")));

ChannelProvider channelProvider = SpeechSettings.defaultChannelProviderBuilder().setCredentialsProvider(credentialsProvider).build();

SpeechSettings settings = SpeechSettings.defaultBuilder().setChannelProvider(channelProvider).build();

// Instantiates a client
SpeechClient speech = SpeechClient.create(settings);

Answer 3

我知道这个答案太晚了。但我也遇到了版本和过时函数的问题。下面是更新后的工作代码。

    InputStream inputStream = Your.class.getResourceAsStream("path/to/the/credentials/file.json");
    GoogleCredentials credentials = GoogleCredentials.fromStream(inputStream);
    CredentialsProvider credentialsProvider = FixedCredentialsProvider.create(credentials);

    TextToSpeechSettings settings = TextToSpeechSettings.newBuilder()
            .setCredentialsProvider(credentialsProvider)
            .build();

    TextToSpeechClient textToSpeechClient = TextToSpeechClient.create(settings);

希望这对某些人有帮助！
