Great tutorial! this is just memo for other beginners. ●can't test in lambda console? try something like this ↓ { "queryStringParameters":{ "transactionId": "5", "type": "purchase", "amount": "100" } } ●internal server error? you need equal in line 25 ↓ responseObject['headers'] = {} and check typos . Thanks!

OMG, thank you sooooo much for this video!!! Building a simple website for my wedding in a few months and wanted to be able for folks to RSVP online and the data loaded to a dynamoDB server to keep everything organized. Spent literally all day yesterday going thru guides and documentation with no success. Would just be curious if you would need to do anything differently for a post method instead of get. Web design is not my forte, which is why I wanted this project to challenge myself. Thanks again!!!
@BeABetterDev3 жыл бұрын
Hi Kyle! Thanks for watching and congratulations on your wedding. I'm also getting married soon and hope you're able to have a happy day despite covid. In terms of your question, the only difference is that you would select the POST method during the api creation in API gateway. Also, the location of the parameters being passed into your lambda function will change (they will likely no longer be in the query param's field, but instead in the 'body'). The quickest way to find out where is just to console.log the input object (event) and find out where in the object the param's are being passed. Hope this helps and feel free to reach out if you have any followup Q's.

Hi, Thank you, this de-mystified some of the profoundness of the topic! Very well structured and explained... What is throwing me off, is whether there is a standard structure protocol for the event[] object? Similarly, why cant a straighforward JSON response be sent over through the lambda? Again, is there a standard structure for this responseObject[]? How and where is this responseObject declared? Why can't the lamda return something like so: return { 'statusCode': 200, 'body': json.dumps('Hello from Lambda!'), 'Name1':event['queryStringParameters']['param1'] 'Name2':event['queryStringParameters']['param2'] }

Getting the following error when I tested the lambda function (without using the API gateway endpoint): { "errorMessage": "'queryStringParameters'", "errorType": "KeyError", "stackTrace": [ [ "/var/task/lambda_function.py", 7, "lambda_handler", "transactionId = event['queryStringParameters']['transactionId']" ] ] Any insight on how to fix this? Not sure how everyone is able to use the same code... Seems like there is an issue with the code itself.
@BeABetterDev2 жыл бұрын
Hi there, have you tried to print out the event that has been passed into the lambda function to see if the input contains query string parameter's. It seems like your functions code is trying to access that field but it is not present in the event. One other possibility is that you created a post API instead of a GET API. This will result in the payload been inside the body of the request instead of query string parameter's. Hope this helps.

One thing, you can improve on is to show entire text editor window, on full screen, zoomed in. While editor window is in focus, as @2:58 , we don't need to see the background window. The reason it matters is that people watch this from variety of different screen sizes, and it helps to see text in large fonts.
