[英]Amazon Transcribe on S3 Upload: "[ERROR] BadRequestException: URI provided doesn't point to an S3 object"
我正在對一系列媒體文件嘗試使用 Amazon Transcribe,調整示例文檔代碼並使用本系列作為參考,以適應任何上傳到我指定的媒體 S3 文件夾的內容,但我的測試文件有問題。
上傳桶/文件夾路徑:
'MediaFileUri': https://us-west-2.console.aws.amazon.com/s3/buckets/upload-asr/mediaupload/file.mp4
我已驗證該文件存在並且存儲桶權限授予對 Amazon Transcribe 服務的訪問權限。 我可以使用相同的 URL 開始手動轉錄作業,但不能使用 SDK:我還使用上面的路徑將它直接鏈接到函數中,但沒有結果。 我很欣賞這可能是一個 URL 路徑問題,但在這個主題上沒有看到太多,所以檢查一個明顯的錯誤。
import json
import time
import boto3
from urllib.request import urlopen
def lambda_handler(event, context):
transcribe = boto3.client("transcribe")
s3 = boto3.client("s3")
if event:
file_obj = event["Records"][0]
bucket_name = str(file_obj['s3']['bucket']['name'])
file_name = str(file_obj['s3']['object']['key'])
file_type = file_name.split(".")[1]
s3_uri = create_uri(bucket_name, file_name)
job_name = context.aws_request_id
transcribe.start_transcription_job(TranscriptionJobName = job_name,
Media = {'MediaFileUri': s3_uri},
OutputBucketName = "bucket-name",
MediaFormat = file_type,
LanguageCode = "en-US")
def create_uri(bucket_name, file_name):
CloudWatch 日志失敗報告:

它使用這種格式對我有用:
Media={
'MediaFileUri': f'https://s3-us-west-2.amazonaws.com/{BUCKET}/{KEY}'
},
