Getting Error TypeError: create_task() takes from 1 to 2 positional arguments but 3 were given while creating google cloud tasks

Question

from google.cloud import tasks_v2

import json


GCP_PROJECT='test'
GCP_LOCATION='europe-west6'


def enqueue_task(queue_name, payload, process_url):
  client = tasks_v2.CloudTasksClient()
  parent = client.queue_path(GCP_PROJECT, GCP_LOCATION, queue_name)

  task = {
    'app_engine_http_request': {
      'http_method': 'POST',
      'relative_uri': process_url
    }
  }

  if payload is None:
    return False

  payload = json.dumps(payload)
  converted_payload = payload.encode()

  task['app_engine_http_request']['body'] = converted_payload
  return client.create_task(parent, task)

我在尝试创建 Google Cloud Task 时不断收到以下错误。使用的 Google App Engine 运行时是 python38。它工作正常，但在使用 gcp CLI 部署后突然不工作了。

我刚刚发生了同样的事情（在实时服务器上：/）。事实证明，Cloud Tasks 库在 2.0.0 版本中发生了重大变化。你可以阅读 what you need to do to upgrade here.

您的问题出在这一行：

client.create_task(parent, task)

更新后的库需要使用字典作为位置参数或使用关键字参数。所以这应该可以解决它：

client.create_task(parent=parent, task=task)

编辑：既然我已经为自己完成了这项工作，请查看您的代码，您还必须更改以下内容：

# Before
parent = client.queue_path(GCP_PROJECT, GCP_LOCATION, queue_name)
# After
parent = client.queue_path(project=GCP_PROJECT, location=GCP_LOCATION, queue=queue_name)

和

# Before
'http_method': 'POST',
# After
'http_method': tasks_v2.HttpMethod.POST,
