Configure access credentials using environment variables

1. Notes:

   1. An AccessKey for an Alibaba Cloud account has access permissions for all APIs. This poses a high security threat. We strongly recommend that you create and use a Resource Access Management (RAM) user for API access or daily O&M. To create a RAM user, log on to the RAM console.

   2. We strongly recommend that you do not hardcode your AccessKey ID and AccessKey secret in your code because this can lead to security threats. This document describes how to store and access your credentials by configuring environment variables.

2. Method for configuring Linux and macOS

   export NLP_AK_ENV=<ACCESS_KEY_ID>
   export NLP_SK_ENV=<ACCESS_KEY_SECRET>

   Replace <ACCESS_KEY_ID> with your AccessKey ID and <access_key_secret> with your AccessKey secret. For more information about how to obtain an AccessKey ID and an AccessKey secret, see Step 2: Obtain an AccessKey for your account.

3. Configuration method for a Windows system

   1. Create an environment variable file. Add the NLP_AK_ENV and NLP_SK_ENV environment variables. Then, set their values to your AccessKey ID and AccessKey secret.

   2. Restart the Windows operating system.

 * This example shows how to store the AccessKey ID and AccessKey secret in environment variables. You can also store them in a configuration file as needed.
 * We strongly recommend that you do not hardcode your AccessKey ID and AccessKey secret in your code. This can lead to security threats.

You probably thought I was going to suggest baking soda or a special range hood cleaner, right? Nope! Like I said, this is an everyday method. Everyone has soap and toilet paper. I've tested this myself: crush a leftover piece of soap into a paste. Use an old toothbrush or just your hands to spread it on the range hood. Use warm water! After a few minutes, the grease will dissolve on its own. Then, just wipe it off with toilet paper. There's no need to take the range hood apart at all. It'll be sparkling clean! Dish soap and white vinegar. Many people have tried using dish soap to clean their range hoods, but maybe without much success. I suggest mixing dish soap with white vinegar to scrub the range hood's panel and grease trap. To clean the grease trap, remove it and soak it in warm, soapy water for about half an hour. Then, wipe it with a cloth, and you'll see a big difference! You can do both of these methods at home without buying a lot of special tools. To clean your range hood, give them a try!");
