I am trying to return data in JSON format from a Google Cloud Function written in Java. I have an example from GoogleCloudPlatform/java-doc-samples (https://github.com/GoogleCloudPlatform/java-docs-samples/blob/main/functions/http/http-method/src/main/java/functions/HttpMethod.java) that shows me how to handle different types of HTTP methods, but it doesn't show how to write JSON in the response.

What I'd like to do would be something like the following:

This article explains how to handle authentication from an end-user with Identity Platform.

The crux seems to be that the client should authenticate with Identity Platform to get a token. That's straightforward enough and I've been able to retrieve the token from the client side code. The server side should receive the token from the client in a request header. But the article doesn't seem to explain what to do after this point. We can get the user with the Identity Platform SDK, but what if the token is invalid? Should we just throw an exception so that the gRPC call errors out?

There is a Java sample and you can that is what it does here. In the sample it returns a Forbidden 403 HTTP status.

But, my assumption is that Cloud Run would have a more automatic level of integration than this. This requires the Cloud Run gateway to send a request to the gRPC service, and get the response. Theoretically, that would allow a malicious actor to continuously hit the gateway with spam tokens that could potentially cost money. If we simply return an error, how are we protected from malicious actors pounding our services? Does the gateway automatically block the IP address if the gRPC service returns too many errors? How does it know which errors should trigger this? A HTTP error of 403 could alert the gateway that the endpoint is getting attacked, but what about gRPC?

I am referring below URL to convert CSV to Avro

https://github.com/GoogleCloudPlatform/java-docs-samples/blob/master/dataflow/transforms/src/main/java/com/example/CsvToAvro.java

my requirement, I have a "map" as a field in my CSV.

{id=1,name=rahul,{address1=Pune,address2=Hyderabad},phone:78888888888}

Now it will fail for {address1=Pune,address2=Hyderabad} this field as it type of MAP.

Anyone, could you please let me know how to solve this.

tl;dr: Why does this work locally but not when I deploy to my live App Engine project?

I'm trying to create a barebones servlet-based web app using the Java 11 version of App Engine. I'm updating a few projects from Java 8 to Java 11 following this guide. I'm also using this guide and this example. My goal is to use Jetty to run a very simple web app that serves a single static HTML file and a single servlet file in App Engine.

My web app works fine when I run locally:

I'm at the following step of a GCP openapi guide where I have to run a maven command to generate an openapi.json file.

I'm following along with my own project, so this may or not be reproducible by just forking the example repository. (so I wouldn't, because I link my own below)

So when I run the command they tell me to, I get the following stack trace, complaining that they can't find my api class, when it very clearly exists.

I forked a repository from base https://github.com/GoogleCloudPlatform/java-docs-samples

Made updates on a new branch and submitted a pull request

The reviewers/collaborators suggested and made changes to files. I chose "Resolve Conversation" and can see the changed files.

Questions:

1. How can i bring the changes done by reviewers on the PR 2972 into my local branch "ksurendra:helidon-mp-example-appengine-java11"?

2. And do i still need to get all the changed files into my local repository branch, verify and then "push" again to the PR 2972? Or do the reviewers already have the necessary changed files? If so, is it that i just need to update my repo/branch to have the updated files?

The details on this page are not clear enough.

I am attempting to create some GCP VMs using the API client libraries for Java, but the examples that I have seen seem to be old. I started with this https://github.com/GoogleCloudPlatform/java-docs-samples/blob/master/compute/cmdline/src/main/java/ComputeEngineSample.java but it looks like the GoogleCredential class is deprecated. After some research I came up with this code
