我如何将变量传递给Google Cloud函数

Question

我当前正在创建一个云任务，该任务将定期将新数据导入到automl数据集中。目标是GCP云功能http目标。因为我不想在云函数中对数据集ID进行硬编码。我希望它接受来自Web UI的数据集ID。因此，我以这种方式键入了烧瓶的代码。

@app.route('/train_model', methods=["POST", "GET"])
def train_model():
    if request.method == 'POST':
        form = request.form
        model = form.get('model_name')
        date = form.get('date')
        dataset_id=form.get('dataset_id')
        datetime_object = datetime.strptime(date, '%Y-%m-%d %H:%M:%S')
        timezone = pytz.timezone('Asia/Hong_Kong')
        timezone_date_time_obj = timezone.localize(datetime_object)

        # Create a client.
        client = tasks_v2beta3.CloudTasksClient.from_service_account_json(
            "xxx.json")

        # TODO(developer): Uncomment these lines and replace with your values.
        project = 'xxxx'
        dataset_id = dataset_id
        utf = str(dataset_id, encoding='utf-8')
        location = 'us-west2'
        url='https://us-central1-cloudfunction.cloudfunctions.net/create_csv/' + "?dataset_id=dataset_id"

        queue1 = 'testing-queue'

        parent = client.queue_path(project, location, queue1)
        task = 
            "http_request": 
                'http_method': 'POST',
                'url': url
            

        # set schedule time
        timestamp = timestamp_pb2.Timestamp()
        timestamp.FromDatetime(timezone_date_time_obj)
        task['schedule_time'] = timestamp
        response = client.create_task(parent, task)

        print(response)
        return redirect(url_for('dataset'))

云功能代码

import pandas
from google.cloud import datastore
from google.cloud import storage
from google.cloud import automl

project_id=123456995
compute_region='us-central1'


def create_csv(dataset_id):

    datastore_client = datastore.Client() #
    data = datastore_client.query(kind='label'.format(dataset_id))
    storage_client = storage.Client()
    metadata = list(data.fetch())
    path = []
    label = []
    for result in metadata:
        path.append(result['Storage_url'])
        label.append(result['label'])
    record = 
        'Path': path,
        'Label': label
    
    table = pandas.DataFrame(record)
    csv_pandas = table.to_csv('/tmp/label.csv', header=None, index=None) #create csv through query datatore

    # upload to cloud storage bucket

    bucket_name1='testing'
    destination_blob_name='label.csv'

    bucket = storage_client.bucket(bucket_name1)
    blob = bucket.blob(destination_blob_name)
    blob.upload_from_filename('/tmp/label.csv')

    object = bucket.get_blob(destination_blob_name)
    bucket = object.bucket
    bucket_name = bucket.name
    url = 'gs://' + bucket_name + '/' + object.name

      #import data to the dataset
    client= automl.AutoMlClient()
    dataset_full_id = client.dataset_path(
        project_id, "us-central1", dataset_id
    )
    # Get the multiple Google Cloud Storage URIs
    input_uris = url.split(",")
    gcs_source = automl.types.GcsSource(input_uris=input_uris)
    input_config = automl.types.InputConfig(gcs_source=gcs_source)
    # Import data from the input URI
    client.import_data(dataset_full_id, input_config)

但是它给了我这个错误。
