Question

我正在将Visual Studio for Mac用于使用Google Speech API的.NET Console C＃项目。

我收到一条错误消息：

Grpc.Core.RpcException: 'Status(StatusCode=Unavailable, Detail="Getting metadata from plugin failed with error: Exception occurred in metadata credentials plugin. Google.Apis.Auth.OAuth2.Responses.TokenResponseException: Error:"invalid_grant", Description:"Robot is disabled.", Uri:""

在代码中我标记为“ // error here”的行上

class Program
{
    static void Main(string[] args)
    {
        var URI = "https://speech.googleapis.com/v1/speech:recognize?key=[API_KEY]";

        Console.WriteLine("Start!");

        AsyncRecognizeGcs(URI);

        Console.WriteLine("End.");

    }

    static object AsyncRecognizeGcs(string storageUri)
    {
        var speech = SpeechClient.Create();
        var longOperation = speech.LongRunningRecognize(new RecognitionConfig()
        {
            Encoding = RecognitionConfig.Types.AudioEncoding.Flac,
            SampleRateHertz = 44100,
            AudioChannelCount = 2,
            LanguageCode = "en",
        }, RecognitionAudio.FromStorageUri(storageUri)); // error here
        longOperation = longOperation.PollUntilCompleted();
        var response = longOperation.Result;
        foreach (var result in response.Results)
        {
            foreach (var alternative in result.Alternatives)
            {
                Console.WriteLine($"Transcript: { alternative.Transcript}");
            }
        }
        return 0;
    }

}

该如何解决？我需要在Google上设置其他内容吗？

Answer 1

推荐更新到新版本的Google.Cloud.PubSub.V1，它将引入新版本的Grpc.Core。使用Google.Apis.Auth的最新更新。

Answer 2

原来，我的凭证json文件错误。愚蠢的错误。

Google.Apis.Auth.OAuth2.Responses.TokenResponseException：invalid_grant，机器人已禁用
