Python urllib3 Lambda：LocationValueError：未指定主机HTTP Webhook

如何解决Python urllib3 Lambda：LocationValueError：未指定主机HTTP Webhook

我正在使用urllib3库和python3 lambda代码，这些代码从AWS Secret Manager中获取MSTeams的webhook网址，并发送http post请求以发布SNS消息。

我的webhook url带有https a的星星看起来像这样“ https：//outlook.office.com/webhook / .......”。执行lambda函数时，出现如下所示的LocationValueError: No host specified

错误

代码

import urllib3 

http = urllib3.PoolManager() 

MSTEAMS_WEBHOOK_SECRET_NAME = os.getenv('MSTEAMS_WEBHOOK_SECRET_NAME') 
HOOK_URL = get_secret(MSTEAMS_WEBHOOK_SECRET_NAME) 

def lambda_handler(event,context):
 message = {
      "@context": "https://schema.org/extensions","@type": "MessageCard","themeColor": data["colour"],"title": title,"text": "accountId:\n"  + account_id + " <br/>\n" 
    }
 
    webhook_encoded_body = json.dumps(message).encode('utf-8')
    response = http.request('POST',HOOK_URL,body=webhook_encoded_body)
 

**在Python 3.7 lambda执行引擎上测试时出错**

Traceback (most recent call last):
  File "/var/task/lambda_function.py",line 145,in lambda_handler
    resp = http.request('POST',body=webhook_encoded_body)
  File "/var/runtime/urllib3/request.py",line 80,in request
    method,url,fields=fields,headers=headers,**urlopen_kw
  File "/var/runtime/urllib3/request.py",line 171,in request_encode_body
    return self.urlopen(method,**extra_kw)
  File "/var/runtime/urllib3/poolmanager.py",line 325,in urlopen
    conn = self.connection_from_host(u.host,port=u.port,scheme=u.scheme)
  File "/var/runtime/urllib3/poolmanager.py",line 231,in connection_from_host
    raise LocationValueError("No host specified.")```
