Writing a Lambda function

- [Instructor] So now we're going to update our code…in the Cloud9 IDE to fetch data for a given user.…So I'm going to delete all the code that's in here…and replace it with this code that I've provided for you…in Chapter five, video three, snippet.txt.…You'll find that in your exercise files…so I'll paste that in here.…Now if we step through this code, we see that…it's looking for a body being passed in…and then within that body, a user ID.…Next, it's going to open up a database table…and we have to get that database table information here.…

And then it's going to create a query,…and then it's going to cycle through the items…and create the JSON to return back in the body.…So we need to get our table name.…So let's go back to services and go to the DynamoDB.…Let's look for our table and here it is.…So let's copy this out and put it in our code,…and we'll save that.…Now we want to test this code by passing in…something reasonable for the test data.…

So I'm going to pass in the body, just like it's expecting,…and I'll have the value for body as a string…
