Google.Apis.Auth.OAuth2.Responses.TokenResponseException: invalid_grant, 机器人被禁用

Question

我将 Visual Studio 用于 Mac 用于使用 Google 语音 API.

的 .NET 控制台 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:""

在代码中我用注释“// error here”标记的行：

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;
    }

}

我该如何解决这个问题？我还需要用 Google 设置什么吗？

Answer 1

建议更新到 Google.Cloud.PubSub.V1 的新版本，这将引入更新版本的 Grpc.Core。 使用 Google.Apis.Auth.

的最后更新

Answer 2

原来我的凭据 json 文件有误。愚蠢的错误。
