Python Google Cloud功能连接由同行重置

Question

从Python中的Google Cloud功能使用Firebase存储API时,我收到连接重置错误.

部署的函数调用一个blob-get ie

from firebase_admin import storage

def fn(request):
  bucket = 'my-firebase-bucket'
  path = '/thing'
  blob = storage.bucket(bucket).get_blob(path)

失败是间歇性的; 该功能的成功率约为90%.

在部署后第一次调用函数时,似乎更有可能失败.

云功能是无状态的，但是可以重用先前调用中的全局状态。提示和这些文档中对此进行了说明。

将全局状态与重试一起使用应为您提供更强大的功能：

from tenacity import retry, stop_after_attempt, wait_random
from firebase_admin import storage

@retry(stop=stop_after_attempt(3), wait=wait_random(min=1, max=2))
def get_bucket(storage):
    return storage.bucket('my-firebase-bucket')

@retry(stop=stop_after_attempt(3), wait=wait_random(min=1, max=2))
def get_blob(bucket, path):
    return bucket.get_blob(path)

bucket = get_bucket(storage)

def fn(request):
  path = '/thing'
  blob = get_blob(bucket, path)
  # etc..
