尝试导入 lambda 时没有名为“requests_aws4auth”的模块

Question

我需要我的 lambda 来调用 API 网关，并在我的云形成模板中将以下代码作为 lambda 的内联代码。

from requests_aws4auth import AWS4Auth
def handler(event,context):
          client = boto3.client('sts')
          responseAssumeRole = client.assume_role(
            DurationSeconds=3600,
            RoleArn='arn',// real arn of the api gateway invocation role
            RoleSessionName='Bob',
          )
          credentials = responseAssumeRole['Credentials']
          auth = AWS4Auth(aws_access_key=responseAssumeRole['Credentials']['AccessKeyId'],
                                 aws_secret_access_key=responseAssumeRole['Credentials']['SecretAccessKey'],
                                 aws_host='host.execute-api.us-east-1.amazonaws.com',
                                 aws_region='us-east-1',
                                 aws_service='execute-api')
          headers= {'User-Agent' : 'Mozilla/5.0 (Windows NT 6.1) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/41.0.2228.0 Safari/537.36'}
          response = requests.get('https://host.execute-api.us-east-1.amazonaws.com/test',
                                  auth=auth, headers=headers)

这给了我以下错误

No module named 'requests_aws4auth'

任何使用 aws 凭据创建身份验证的解决方案或替代方法也将受到欢迎。

将源代码和依赖项打包到 zip 文件中，将其上传到 S3，然后使用 AWS::Lambda::Function 资源下的 S3Bucket 和 S3Keys 属性。

例如在 Linux 上：

mkdir project-dir
cp myhandler.py project-dir
pip install module-name -t /path/to/project-dir

# zip the contents of project-dir , this is your deployment package
cd project-dir
zip -r deployme.zip .
