Azure AI Translation无法访问Blob存储文档问题
我在Azure Web应用中使用Azure AI Translation时遇到问题：无法访问Blob存储中的文档。我希望从Blob存储取出一个Blob/文档进行翻译，再将结果存入目标容器，但收到以下错误：
'innerError': {'code': 'NoDocumentsFound', 'message': 'No document found in source with the given path and filters.'}
奇怪的是，把生成的源Blob URL复制到浏览器中，能正常找到并下载该文档。
代码实现
def translate_single_blob(client, blob_ID): subscription_key = settings.AZURE_TRANSLATOR['SUBSCRIPTION_KEY'] endpoint_document = settings.AZURE_TRANSLATOR['DOCUMENT_TRANSLATION_ENDPOINT'] region = settings.AZURE_TRANSLATOR['REGION'] target_language = "fr" # 可修改为目标语言（如'fr'代表法语） version = '2024-05-01' blob_service_client = BlobServiceClient.from_connection_string(os.getenv("STORAGE_CON_STRING")) target_container_name = "translated-blobs" create_storage_container(os.getenv("STORAGE_CON_STRING"), target_container_name) #target_container = blob_service_client.get_container_client(target_container_name) try: blobs = client.list_blobs() for blob in blobs: blob_client = client.get_blob_client(blob) blob_props = blob_client.get_blob_properties() metadata = blob_props.metadata if metadata: metadata_id = metadata.get("id", "").lower() # 访问metadata中的"id"键 if metadata_id == blob_ID.lower(): # 转为小写进行不区分大小写的匹配 sas_token = generate_blob_sas( account_name=blob_service_client.account_name, account_key=os.getenv("AZURE_ACCOUNT_KEY"), container_name=blob_props.container, blob_name=blob_props.name, permission=BlobSasPermissions(read=True, list=True), expiry=datetime.utcnow() + timedelta(minutes=15) ) blob_url = f"{blob_client.url}?{sas_token}" sas_token_target = generate_container_sas( account_name=blob_service_client.account_name, account_key=os.getenv("AZURE_ACCOUNT_KEY"), container_name=target_container_name, permission=ContainerSasPermissions(write=True, list=True), expiry=datetime.utcnow() + timedelta(minutes=15) ) container_target_sas_url = f"https://{blob_service_client.account_name}.blob.core.windows.net/{target_container_name}?{sas_token_target}" # 文档翻译请求体 payload= { "inputs": [ { "storageType": "File", "source": { "sourceUrl": f"{blob_url}", "storageSource": "AzureBlob", "language": "en" }, "targets": [ { "targetUrl": f"{container_target_sas_url}", "storageSource": "AzureBlob", "category": "general", "language": f"{target_language}", } ] } ] } headers = { 'Ocp-Apim-Subscription-Key': subscription_key, 'Content-Type': 'application/json' } base_path = f'{endpoint_document}/translator/document/batches' route = f'?api-version={version}' constructed_url = base_path + route response = requests.post(constructed_url, headers=headers, json=payload) print(f'response status code: {response.status_code}\nresponse status: {response.reason}\nresponse headers: {response.headers}') time.sleep(5) if response.status_code == 202: job_id = response.json().get('id') i = 0 while i < 5: # Azure Translator API配置 # 构造URL url = f"{endpoint_document}/translator/document/batches/{job_id}?api-version={version}" # 设置请求头 headers = { "Ocp-Apim-Subscription-Key": subscription_key, "Ocp-Apim-Subscription-Region": region, } # 发送GET请求 response = requests.get(url, headers=headers) # 检查响应状态 if response.status_code == 200: # 解析JSON响应 result = response.json() print("Translation Status:") print(result) i = 5 else: i +=1 time.sleep(5) print(f"Failed to get translation status. HTTP Status Code: {response.status_code}") print(f"Response: {response.text}") return True else: print(f"Translation initiation failed. Status Code: {response.status_code}, Response: {response.text}") return False print(f"No blob found with ID '{blob_ID}'.") return False except Exception as e: print(f"An error occurred while translating blob with ID '{blob_ID}': {str(e)}") return False
问题排查说明
如代码所示，我为源URL添加了具备读取权限的SAS令牌，为目标URL添加了具备写入权限的SAS令牌。同时在Azure门户中为翻译器配置了标识，使其在Blob存储上拥有Contributor角色，但问题仍然存在。有没有人遇到过类似问题并找到了解决方案？
