How to access the raw query string (or full URL) in a Chalice (AWS Lambda/API Gateway) app?

由 烈酒焚心 提交于 2021-02-19 06:01:34
问题 I'm using Chalice to build a fairly straightforward API on AWS Lambda & API Gateway. I need a way to get access to the raw query string (i.e foo=bar&abc=123 ). When accessing the app.current_request.query_params dictionary, it's already been processed, such that any empty parameters ( foo=&bar= ) have been stripped out. Unfortunately I'm working with a third-party API that sends a signed hash value in the query string, based off the raw query string. I can't verify it without the original,

问题 We implement almost all our lambda's in Chalice and then consume them in CDK project as described here. I need to add same environment variable to all lambda's in stack (different per developer). I would like to do it automatically, and not count on every developer adding variable to Chalice stage configuration. I can't use AWS Systems Manager Parameter Store, because it's the same for all dev stacks - we share the same AWS account. I can parse final cloudformation template before deploy and

AWS Chalice Return an Image File from S3

问题 I am using Chalice to build a simple severless application which returns an image file from S3. I am able to return file after it is 64 bit encoded. But I am wondering how I can return the binary file so that user can take it as a file download? My following code is not working. @app.route('/binary_object/{bucket}/{key}', methods=['GET', 'PUT']) def binary_object(bucket, key): request = app.current_request if request.method == 'GET': try: file_path = '/tmp/{}_{}'.format(uuid.uuid4(), key) s3
