Question

我正在关联AWS Cloudfront中的lambda函数。在关联cloudfront的Web分发的行为模式中的函数时，我得到以下错误：

com.amazonaws.services.cloudfront.model.InvalidLambdaFunctionAssociationException: The function has an invalid runtime for functions that are triggered by a CloudFront event: python2.7 Expecting: nodejs6.10 Function: arn:aws:lambda:us-east-1:316211033416:function:domain_redirects:1 (Service: AmazonCloudFront; Status Code: 400; Error Code: InvalidLambdaFunctionAssociation; Request ID: 8771bb2b-3b50-11e8-a02b-47ca03858fe8)

python lambda函数：

from __future__ import print_function

import json

print('Loading function')


def domain_redirects(event, context):
    #print("Received event: " + json.dumps(event, indent=2))
    request=event['Records'][0]['cf']['request']
    headers=request['headers']
    mob_device=["android","iphone","googlebot-mobile"]
    user_agent=headers['user-agent'][0]['value'].lower()
    for device in mob_device:
        if device in user_agent:
            response = {
                'status':'302',
                'statusDescription':'Found',
                'headers': {
                    'location': [
                    {
                    'key': 'Location',
                    'value': 'http://m.bakewish.in'
                    }
                    ],
                }
            }
            # print (device + "detected")
            return response

创建lambda函数的角色具有以下信任关系：

{
  "Version": "2012-10-17",
  "Statement": [
    {
      "Effect": "Allow",
      "Principal": {
        "Service": [
          "lambda.amazonaws.com",
          "edgelambda.amazonaws.com"
        ]
      },
      "Action": "sts:AssumeRole"
    }
  ]
}

任何帮助表示赞赏!!

查看documentation看起来你必须使用nodejs6.10运行时来使用cloudfront来处理cloudda。

您必须使用nodejs6.10运行时属性创建函数。

AWS cloudfront无效的Lambda函数关联异常
