Question

我见过几次类似的问题，并提出了一些建议的步骤来解决我认为已经遵循的问题。除了我在一个程序中执行所有操作外，代码完全是示例中的示例...将文件加载到GCS，然后尝试使用Vision处理文件。我在顶部设置了一个环境变量，我认为这对两个函数都适用...文件已成功上传到GCS浏览器并已确认URI。权限被拒绝错误令人困惑，因为凭据具有所有者权限...

有什么想法吗？客户端client.async_batch_annotate_files ..被调用后，该对象即消失

->操作= client.async_batch_annotate_files（requests = [async_request]）（Pdb） google.api_core.exceptions.PermissionDenied：403打开文件时出错：gs：//test_documents/uploads/2c4cd57cea679abd7dde9b20023a6c2c.pdf。

from google.cloud import vision
from google.cloud import storage
from google.protobuf import json_format
os.environ["GOOGLE_APPLICATION_CREDENTIALS"]=config.gstorage
mime_type = 'application/pdf'
batch_size = 2

doc = DocumentMaster.objects.get(document_id=14)
bname = 'test_documents'
fname = doc.document_hash_key+".pdf"
in_target = os.path.join("uploads",fname)
out_target = os.path.join("document_json",fname)

fullpath = os.path.join(bname,in_target)
fullpath2 = os.path.join(bname,out_target)
private_in = "gs://"+fullpath
private_out = "gs://test_documents/document_json"

CloudStorage = storage.Client()
StorageBucket = CloudStorage.get_bucket(bname)
blob = StorageBucket.blob(in_target)
blob.upload_from_filename(doc.document_original.path)

client = vision.ImageAnnotatorClient()

feature = vision.types.Feature(type=vision.enums.Feature.Type.DOCUMENT_TEXT_DETECTION)

gcs_source = vision.types.GcsSource(uri=private_in)
input_config = vision.types.InputConfig(gcs_source=gcs_source, mime_type=mime_type)
gcs_destination = vision.types.GcsDestination(uri=private_out)
output_config = vision.types.OutputConfig(gcs_destination=gcs_destination, batch_size=batch_size)

async_request = vision.types.AsyncAnnotateFileRequest(features=[feature], input_config=input_config,output_config=output_config)

operation = client.async_batch_annotate_files(requests=[async_request])
print('Waiting for the operation to finish.')
operation.result(timeout=30)

Answer 1

结果我低估了GCS云存储中特定管理员的状况。虽然该项目具有服务帐户，但还需要明确授权它才能检索刚上传的文件...关闭
