How do I use environment variables for API tokens?
You can store API tokens in environment variables to keep them secure. This way, they won't be hard-coded in your code.
Can you show me how to set an environment variable in Python?
Sure! You can use the os
module. First, set the variable in your terminal: export API_TOKEN='your_token'
. Then, in Python, access it with import os
and os.getenv('API_TOKEN')
.
What if I'm using a different programming language?
The concept is similar across languages. Most have a way to access environment variables. For example, in Node.js, you can use process.env.API_TOKEN
.
Are there any security risks I should be aware of?
Yes, ensure your environment variables are not exposed in logs or error messages, and avoid sharing your environment files.
