从 java 项目中的 html 文件访问 .env 变量

Question

I have a java project which contains an index.html file. In this html file, I need to access an API key. I store this API key in GOOGLEMAP_API_KEY variable inside my .env file. However, I don't know how to access this GOOGLEMAP_API_KEY variable in index.html in my java project.

My .env file looks something like this:

GOOGLEMAP_API_KEY=ABCDEFGHijklmnopqrst12345

I tried to access the GOOGLEMAP_API_KEY variable in my index.html file with this line:

<script src="https://maps.googleapis.com/maps/api/js?key=process.env.GOOGLEMAP_API_KEY&callback=initMap"></script>

This doesn't work and I don't know how to make it work. Please help. Thanks in advance.

Answer 1

you can't access the .env (environment variable) from the HTML, you need an environment or framework that she can work with him, please read more about node.js and Django this two environment is so popular and can work with .env

the HTML is not a programming language it's the standard markup language for documents designed to be displayed,

try javascript to start developing and read more about this javascript and node.js can help you to read variables from .env

and then please check this documentation to know how to read variables from .env
