Connect to Google Cloud Datastore using dev_appserver.py and google.golang.org/

php editor Strawberry will introduce you how to use dev_appserver.py and google.golang.org/ to connect to Google Cloud Datastore. dev_appserver.py is a development server that can simulate the Google App Engine environment, while google.golang.org/ is an official code library of the Go language. Using the two together, you can easily connect to Google Cloud Datastore and read and write data. In this article, we will explain the specific steps in detail to help you get started quickly and successfully connect to Google Cloud Datastore.

Question content

Just as the title says. We have an older Go 1.11 AppEngine API that requires dev_appserver.py to run. In short, I want appengine.Main() and appengine.NewContext(r) to allow my application to point to me using my project-id Cloud data storage instead of local simulator storage. I set GOOGLE_APPLICATION_CREDENTIALS to no avail.

This way I can run the server locally while accessing the shared cloud database.

I'm using google.golang.org/[email protected] and dev_appserver.py --enable_console --port=8081 --support_datastore_emulator=true --go_debugging=true app.yaml

is it possible? Or am I stuck on the local emulator when using the old Go library?

Solution

Move from comments to answers

1. View go 1.11’s remote_api https://www.php.cn/link/2d680487650d66445b50d3d759eccad4

2. The logic of using it is similar to -

   If running in local environment, use remote_api Otherwise stick to default behavior (i.e. since remote_api is not enabled, it will use emulator in local environment or directly in production Using production data)

   For simplicity, you can try using the same variable name, i.e.

   if this is local environment
    ctx, err := remote_api.NewRemoteContext(host, hc)
   else
    ctx := appengine.NewContext(r)

   You then use "ctx" in the rest of your queries/calls to the datastore

   NOTE: I am not familiar with "go" so consider the above as pseudocode rather than working code

3. You may also want to consider running the above changes without the --support_datastore_emulator=true flag
