cache-store-value duration - how to use expression for duration?

Question

<cache-store-value key="foo" value="bar" duration="@((string)context.Variables["accesstoken-exp"])" />

When I try to save it, I get an error Cannot implicitly convert type 'string' to 'int'.

How can I specify duration as an expression?

Answer 1

Hi - thanks for the question

The context variables is a generic string,object dictionary

So long as the value was an integer in the first place (e.g. as a result of an expression which returned an integer) you can read it as such

context.Variables.GetValueOrDefault<int>("duration")

Or if the value was added as a string literal

int.Parse(context.Variables.GetValueOrDefault<string>("duration"))

Example , note i need the tostring because the value is an int

<set-variable name="durationseconds" value="@(60)" />
<set-header name="demo" exists-action="override">
     <value>@(context.Variables.GetValueOrDefault<int>("durationseconds").ToString())</value>
</set-header>

@Martin Kallukalam Thanks for reaching out. To resolve the error "Cannot implicitly convert type 'string' to 'int'", you need to ensure that the duration parameter is an integer. Here is the corrected policy:

In this example, int.Parse is used to convert the string value of accesstoken back to an integer, which is then used as the duration. This should resolve the type conversion error.

do let me know incase of further queries, I would be happy to assist you.
