问题
In an Microsoft Azure Web App Service under Application Settings, there are Key-Value pair options within the option App Settings. If a developer has PHP or Python files in multiple directories, which of these directories and (or) files would have access to these key-value pairs.
Example:
Suppose the developer has the following key value pair settings in App Settings:
Key: $variableString | Value: "My first example string."
Key: $variableNumber | Value: 1000
PHP files:
site\wwwroot\index.php
site\wwwroot\folderone\pageone.php
site\wwwroot\folderone\pagetwo.php
site\wwwroot\foldertwo\page.php
Would all these files have access to these variables, or would these files need to have a reference (and where?) to where these key-value pairs would be saved like in each PHP file with an include pointer to the App Settings file (Azure doesn't show this becomes a file)?
Thanks.
回答1:
They will be available as environment variables so it doesn't matter where the file is.
If you set an app setting with key ITEM_COUNT and value 15, you could use:
$item_count = getenv('ITEM_COUNT');
Or:
$item_count = getenv('APPSETTING_ITEM_COUNT');
And $item_count would contain the string "15".
回答2:
Anything that can access environment variables can access those, as those are environment variables. So python would be able, not sure about php, since I know nothing about it, but pretty sure it could.
In my code I just use this:
"{0}-{1}".format(os.getenv('LOCATION'), os.getenv('COMPUTERNAME'))
