问题描述
如何在传入的Cloudfront请求中提取承载令牌,并在另一个get请求中使用它.
How can I extract the bearer token in incoming cloudfront request and use it in another get request.
curl -X GET \
https://domain/api/files/7d0ab8ef-9061-4458--de79a2c9e436 \
-H 'Authorization: Bearer eTA' \
-H 'Cache-Control: no-cache' \
-H 'Postman-Token: token'
在以下请求中将承载令牌用作jwt
use the bearer token as jwt in the following request
in phython domain.com/service/api/files/7d0ab8ef-9061-4458--de79a2c9e436
这给了我以下答复:
https://domain/file-service/api/files/7d0ab8ef-9061-4458-b97a-de79a2c9e436
{
"id": "7d0ab8ef-9061-4458-b97a-de79a2c9e436",
"uploadId": "-9b68-44bd-864a-cd9a40d601ba",
"consumerId": "-97d1-11ea-bb37-0242ac130002",
"metadata": {
"fileName": "somefile.docx",
"fileSize": 1000,
"mimeType": "application/msword"
},
"objectKey": "2020-04-31/ju-28fc-4d7c-b086-66c15eb311e7.docx",
"status": "PENDING"
}
我的lambda代码如下所示
My lambda code looks like this
import json
def lambda_handler(event, context):
# TODO implement
request = event['Records'][0]['cf']['request']
print(request['headers'])
print(response)
推荐答案
您将其添加为查看器请求事件的Lambda @ Edge函数.
You would add this as a Lambda@Edge function for the viewer request event.
Lambda @ Edge如下所示
The Lambda@Edge would look like the following
import json
import requests
def lambda_handler(event, context):
request = event['Records'][0]['cf']['request']
print (request)
print(request['headers'])
print(request['origin']['s3']['domainName'])
token = request['headers']['cookie'][0]['value'].partition("=")[2]
print (token)
print(type(request['uri']))
cosumer_id = request['uri'].rpartition('/')[-1]
print (cosumer_id)
#Take the token and send it somewhere
token_response = requests.get(url = 'https://url/api/files/' + cosumer_id, headers = {'Authorization': 'Bearer ' + token})
print (token_response.request)
print (token_response)
print (token_response.text)
data = token_response.json()
objectKey = data["objectKey"]
print (objectKey)
return request
假设您正在使用请求库,则可以像这样检索响应
Assuming you're using the requests library you would be able to retrieve the response like this
object = token_response.objectKey
