AWS的Lambda使用尝试

之前给博客尝试用了CloudFront，今天来试试Lambda。

先给虚拟机装个conda

• wget https://mirrors.tuna.tsinghua.edu.cn/anaconda/miniconda/Miniconda3-py39\_4.12.0-Linux-x86\_64.sh -O conda_install.sh
• chmod +x conda_install.sh
• ./conda_install.sh
• source ~/.bashrc
• nano -K .condarc # 清华镜像源
• conda clean -i

安装python3.9运行时

• conda create -n aws_py39 -c conda-forge python=3.9.13 -y
• conda activate aws_py39
• conda install -c conda-forge zip -y

添加第三方python依赖

• mkdir python
• pip3 install –target ./python -i https://pypi.tuna.tsinghua.edu.cn/simple requests
• zip -r py-requests.zip python
• 下载 py-requests.zip

创建层

创建函数

添加依赖层

编写函数

import json
import requests,base64
 
def getsend(wecom_cid, wecom_aid, wecom_secret):
    get_token_url = f"https://qyapi.weixin.qq.com/cgi-bin/gettoken?corpid={wecom_cid}&corpsecret={wecom_secret}"
    response = requests.get(get_token_url).content
    access_token = json.loads(response).get('access_token')
    if access_token and len(access_token) > 0:
        send_msg_url = f'https://qyapi.weixin.qq.com/cgi-bin/message/send?access_token={access_token}'
        def send(text, wecom_touid='@all'):
            data = {
                "touser":wecom_touid,
                "agentid":wecom_aid,
                "msgtype":"text",
                "text":{
                    "content":text
                },
                "duplicate_check_interval":600
            }
            response = requests.post(send_msg_url,data=json.dumps(data)).content
            return response
    else:
        def send(text, wecom_touid='@all'):
            print('get_token Failed')
    return send
 
### 以下请按实际情况自行配置，以上勿动 ###
 
'''
WECOM_CID企业微信公司ID
WECOM_AID企业微信应用ID
WECOM_SECRET企业微信应用Secret
wecom_touid消息发送对象的UID
'''
info = getsend( # 与Server酱中的参数一致
    wecom_cid = '***',
    wecom_aid = '***',
    wecom_secret = '***'
    )
wecom_touid = 'limour'
### 以上请按实际情况自行配置，以下勿动 ###
 
def lambda_handler(event, context):
    # TODO implement
    args = event.get('body')
    args = json.loads(args)
    if args.get('token') != 'a123456':
        return {
            'statusCode': 404,
            'body': json.dumps('invalid token!')
        }
    response = info(
        text = args.get('msg'),
        wecom_touid = args.get('touid')
        )
    body = {}
    body["event"] = event.get('body')
    return {
        'statusCode': 200,
        "isBase64Encoded": False,
        "headers": {"Content-Type" : "application/json"},
        'body': json.dumps(body)
    }

测试

/usr/bin/curl -X POST \
-H "Content-Type: application/json" \
-d '{"msg": "test msg", "touid":"limour", "token":"a123456"}' \
