python urllib3 lambda错误:LocationParseError无法解析 [英] python urllib3 lambda Error: LocationParseError Failed to parse

问题描述

我正在Lambda中使用urllib3库和python3代码，这些代码可从AWS Secret Manager中获取MSTeams的webhook网址，并发送http发布请求以发布通知.

I'm using urllib3 library in Lambda and python3 code that fetches the webhook url of MSTeams from AWS Secret Manager and sends a http post request to publish a notification.

我的webhook网址以https开头，看起来像这样的"https://outlook.office.com/webhook/.......".执行lambda函数时，出现如下所示的错误 LocationParseError无法解析:

My webhook url starts with https and looks like this "https://outlook.office.com/webhook/.......". On executing the lambda function, I get an error as shown below LocationParseError Failed to parse:

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,"eu-west-1") 

def get_secret(secret_name, region_name):

    # Create a Secrets Manager client
    session = boto3.session.Session()
    client = session.client(
        service_name='secretsmanager',
        region_name=region_name
    )
        get_secret_value_response = client.get_secret_value(
            SecretId=secret_name,
            VersionStage="AWSCURRENT"
        )
        if 'SecretString' in get_secret_value_response:
            secret = get_secret_value_response['SecretString']
            return secret
        else:
            decoded_binary_secret = base64.b64decode(get_secret_value_response['SecretBinary'])
            return decoded_binary_secret


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)

推荐答案

这是我解决的方法

• 再次部署lambda zip文件，并将正确的依赖项(如请求，urllib3)部署在同一文件夹中
• 显然，我试图将密钥作为键/值对存储在AWS Secret Manager中，因此它无法解析字典.我将机密类型更改为纯文本
