Google 语音 API 无法在 Google 存储上找到文件：错误 404

Question

我正在尝试使用 google 云语音将音频剪辑 [.flac 格式] 转换为文本 api.I 我正在使用 python 客户端库发出请求并有一个存储桶在 GCP 上具有用于存储音频文件和异步的扁平目录结构 requests.Below 是用于发出请求的 python 代码

            from google.cloud import storage
            from google.cloud import speech
            from google.cloud.speech import enums
            from google.cloud.speech import types
            import json

            def AudioAnalyze(bucket_name):
                storage_client = storage.Client()
                speech_client = speech.SpeechClient()
                bucket = storage_client.get_bucket(bucket_name)
                bucket_contents = bucket.list_blobs()
                urls = []
                audio_content=[]
                for i in bucket_contents:
                        urls.append("gs://"+i.bucket.name+"/"+i.public_url.split("/")[-1])
                for gcs_uri in urls:
                    audio = types.RecognitionAudio(uri=gcs_uri)
                    config = types.RecognitionConfig(
                    encoding=enums.RecognitionConfig.AudioEncoding.FLAC,
                    sample_rate_hertz=44100,
                    language_code='en-US')
                    operation = speech_client.long_running_recognize(config,audio)
                    print(gcs_uri)
                    print('Waiting for operation to complete...')
                    response = operation.result(timeout=450)
                    speech2text=[]
                    for result in response.results:
                        for alternative in result.alternatives:
                            speech2text.append(alternative.transcript)
                    ad_content=" ".join(speech2text)
                    audio_content.append(ad_content)
                with open("path/to a/json file/file.json","w") as f:
                    json.dump(audio_content,f)


            if __name__=="__main__":
                    AudioAnalyze("adsaudiocontent")

我遇到错误：google.api_core.exceptions.NotFound：404 请求的实体未找到 在存储桶中存在的特定文件上，同时正在处理所有其他文件properly.The 音频文件经过了类似的处理 pipeline.The 音频文件 在我的 public bucket:adsaudiocontent 上可用，因此您可以复制 error.For 这里的附加细节是回溯。

您不小心将 URL 的一部分错误地与“/”匹配，这可能导致了此错误。
