使用 Google Cloud Function 在 Google Cloud 上禁用计费(Keyerror:'data') [英] Disabling Billing on Google Cloud Using Google Cloud Function (Keyerror: 'data')

问题描述

我正在尝试编写一个谷歌云函数来设置上限以禁用超过特定限制的使用.我按照这里的说明操作:

我还附上了一张屏幕截图，以表明我也将相关内容复制并粘贴到了 requirements.txt 文件中.

但是当我去测试代码时，它给了我一个错误:

知道为什么吗?

解决方案

Google 提供的代码似乎有错误.当我更改 stop_billing 函数时，它开始工作了:

def stop_billing(data, context):如果 data.keys() 中的数据":pubsub_data = base64.b64decode(data['data']).decode('utf-8')pubsub_json = json.loads(pubsub_data)cost_amount = pubsub_json['costAmount']budget_amount = pubsub_json['budgetAmount']别的:cost_amount = 数据['costAmount']budget_amount = 数据['budgetAmount']如果 cost_amount <=budget_amount:打印(f'无需任何操作.(当前成本:{cost_amount})')返回如果 PROJECT_ID 为 None:print('没有指定环境变量的项目')返回billing = discovery.build('cloudbilling', 'v1', cache_discovery=False, )项目 = billing.projects()billing_enabled = __is_billing_enabled(项目名称，项目)如果 billing_enabled:__disable_billing_for_project(PROJECT_NAME，项目)别的:print('计费已禁用')

问题是 pub/sub 消息将输入作为带有 base64 编码的数据"条目的 json 消息提供.在测试功能中，您提供没有数据"键且没有编码的 json 条目.这是在我上面重写的函数中检查的.

I am attempting to write a Google Cloud Function to set caps to disable usage above a certain limit. I followed the instructions here: https://cloud.google.com/billing/docs/how-to/notify#cap_disable_billing_to_stop_usage.

This is what my cloud function looks like (I am just copying and pasting from the Google Cloud docs page linked above):

import base64
import json
import os
from googleapiclient import discovery
from oauth2client.client import GoogleCredentials
PROJECT_ID = os.getenv('GCP_PROJECT')
PROJECT_NAME = f'projects/{PROJECT_ID}'
def stop_billing(data, context):
    pubsub_data = base64.b64decode(data['data']).decode('utf-8')
    pubsub_json = json.loads(pubsub_data)
    cost_amount = pubsub_json['costAmount']
    budget_amount = pubsub_json['budgetAmount']
    if cost_amount <= budget_amount:
        print(f'No action necessary. (Current cost: {cost_amount})')
        return

    billing = discovery.build(
        'cloudbilling',
        'v1',
        cache_discovery=False,
        credentials=GoogleCredentials.get_application_default()
    )

    projects = billing.projects()

    if __is_billing_enabled(PROJECT_NAME, projects):
        print(__disable_billing_for_project(PROJECT_NAME, projects))
    else:
        print('Billing already disabled')


def __is_billing_enabled(project_name, projects):
    """
    Determine whether billing is enabled for a project
    @param {string} project_name Name of project to check if billing is enabled
    @return {bool} Whether project has billing enabled or not
    """
    res = projects.getBillingInfo(name=project_name).execute()
    return res['billingEnabled']


def __disable_billing_for_project(project_name, projects):
    """
    Disable billing for a project by removing its billing account
    @param {string} project_name Name of project disable billing on
    @return {string} Text containing response from disabling billing
    """
    body = {'billingAccountName': ''}  # Disable billing
    res = projects.updateBillingInfo(name=project_name, body=body).execute()
    print(f'Billing disabled: {json.dumps(res)}')

Also attaching screenshot of what it looks like on Google Cloud Function UI:

I'm also attaching a screenshot to show that I copied and pasted the relevant things to the requirements.txt file as well.

But when I go to test the code, it gives me an error:

Any idea why?

解决方案

There seems to be an error in the code Google provided. I got it working when I changed the stop_billing function:

def stop_billing(data, context):
    if 'data' in data.keys():
        pubsub_data = base64.b64decode(data['data']).decode('utf-8')
        pubsub_json = json.loads(pubsub_data)
        cost_amount = pubsub_json['costAmount']
        budget_amount = pubsub_json['budgetAmount']
    else:
        cost_amount = data['costAmount']
        budget_amount = data['budgetAmount']
    if cost_amount <= budget_amount:
        print(f'No action necessary. (Current cost: {cost_amount})')
        return    
    if PROJECT_ID is None:
        print('No project specified with environment variable')
        return
    billing = discovery.build('cloudbilling', 'v1', cache_discovery=False, )
    projects = billing.projects()
    billing_enabled = __is_billing_enabled(PROJECT_NAME, projects)
    if billing_enabled:
        __disable_billing_for_project(PROJECT_NAME, projects)
    else:
        print('Billing already disabled')

The problem is that the pub/sub message provides input as a json message with a 'data' entry that is base64 encoded. In the testing functionality you provide the json entry without a 'data' key and without encoding it. This is checked for in the function that I rewrote above.
