This is a simple HTTP function written in Python that can be deployed to Google Cloud Functions. The function responds to HTTP requests with a "Hello, World!" message.

To deploy the function to Google Cloud Functions, you can use the following command:

gcloud functions deploy python-http-function \
  --gen2 \
  --runtime=python311 \
  --region=asia-southeast1 \
  --source=. \
  --entry-point=hello_http \
  --trigger-http \
  --allow-unauthenticated

Make sure to replace python-http-function with the name of your function, and adjust the region and other parameters as needed.

Once the function is deployed, you can send HTTP requests to its URL to trigger it. The function will respond with a "Hello, World!" message.

To trigger the function using a POST request, you can use the following curl command:

curl -X POST \
  -H "Content-Type: application/json" \
  -d '{"name": "Nutty"}' \
  https://<YOUR_FUNCTION_URL>

Make sure to replace <YOUR_FUNCTION_URL> with the URL of your deployed function. This curl command sends a POST request to the function with a JSON payload containing a name field set to "Nutty". The -H option sets the Content-Type header to application/json, and the -d option specifies the data to send in the request body.

To trigger the function using a GET request, you can simply navigate to the URL of your deployed function in a web browser or use the following curl command:

curl https://<YOUR_FUNCTION_URL>?name=Nutty

Make sure to replace <YOUR_FUNCTION_URL> with the URL of your deployed function. This curl command sends a GET request to the function with a query parameter name set to "Nutty". The function will extract the value of the name parameter from the request and respond with a message that includes the value of the name variable.
