问题 I have Amazon Cognito user pool with few users added in it. I have added trigger to invoke my Lambda function after Post confirmation. Do we have any trigger in Cognito to invoke the Lambda function after "User Signout" and "Delete User". I did not see any trigger in Cognito. How the lambda function can be invoked automatically after User signout and Delete user. Kindly throw some light on this. 回答1: TL;DR: Can't be done It can't be done automatically because unlike Sign-in/Sign-ups which

问题 Every time I have a syntax error or I just want to send a custom error in my AWS Lambda function, I get the same 502 Bad Gateway response (Internal server error). I tried that simple code: module.exports.saveImage = (event, context, callback) => { callback("the sky is falling!"); // also tried sending new Error("the sky is falling!") } And still getting the same "Internal server error" response instead of the defined one. This is my function in the serverless.yml file: saveImage: handler:

问题 I have been struggling with API Gateway trying to get what I assumed would be a simple procedure, sending raw JSON from a webhook to my AWS Lambda as an event to use within my function. All I want to do is output the Woocommerce order number and send an email of the order number as well by getting the Woocommerce webhook body to Lambda, like I have in my test event. Here is the function: var AWS = require('aws-sdk'); var ses = new AWS.SES(); exports.handler = (event, context, callback) => { /

问题 I have a POST API Gateway method to which I am sending the following application/json body in order to pass parameters from it to a Lambda that the method is connected to: { "otherClientId": "12345", "message": "Text", "seconds": 0, "hours": 0 } I am using the following mapping template: #set($inputRoot = $input.path('$')) { "authorizedUser": "$context.authorizer.principalId", "otherClientId": "$inputRoot.otherClientId", "message": "$inputRoot.message", "amount": $inputRoot.amount, "duration"

问题 My resource /api has a method POST which proxies the body to Kinesis Firehose (and then to ES). At the same time I want it to trigger a Lambda function. I tried adding an additional method ANY to trigger the Lambda function but API Gateway seems to preference the POST handler. I am aware that I can trigger Lambda on POST and submit from the Lambda function to Firehose but I'd prefer having those two independent from each other. 回答1: API Gateway doesn't fork a request into multiple concurrent

问题 I've added certificate with custom domain name map in AWS API gateway but it allows HTTP automatically, how can I block normal HTTP and only allows HTTPS? 回答1: All API Gateway APIs are fronted with a CloudFront distribution. Each of these CloudFront distributions (whether it's a Custom Domain like yours or the default *.execute-api distribution) is configured to redirect all HTTP requests to HTTPS. Although CloudFront has the option to strictly require HTTPS and return 403 on HTTP requests we

问题 I want to return a pdf from a AWS Lambda function, and I use API Gateway for calling it from a any browser. I have a aws lambda function in c# that returns an API Gateway Response which body is a pdf in base64 encoded string . So far the endpoint returns a file with .pdf extension but not in binary. Instead, is a text file with the base64 string. The headers i'm returning from the c# code are: var headersDic = new Dictionary<string, string>(); headersDic.Add("Content-type", "application/pdf")

问题 I have a SAM template for my application. Each time I deploy my SAM template with a new API Gateway stage name, it replaces the previously created stage. So, found this article which helps me in releasing different versions pointing to different lambda versions. https://aws.amazon.com/blogs/compute/using-api-gateway-stage-variables-to-manage-lambda-functions/ But, for this, I have to change API Gateway manually after deployment. So, Is there any way that I can do this using AWS SAM ? For
