addParam()

The addParam() command retrieves the value associated with a specific key from the query string of the current request and assigns this value to a target variable. This command is useful for extracting values from query parameters in an HTTP request and storing them in variables for processing.

Parameters

• param Type: value Description: The key of the query string whose value you want to retrieve. It should be a value that represents the key in the query string.
• variable Type: var Description: The variable in which the retrieved value from the query string will be stored. It must be a variable that will receive the value associated with the specified key.

Command Flow

Usage Example

Suppose the query string of the current request is ?user=alice&age=30, and you want to retrieve the value associated with the key "user".

// Variable definitions
userName = ''

// Call the command to retrieve the value for the "user" key and assign it to the variable
addParam("user", userName)

// Return the retrieved value through addResult
addResult(userName)

Given the query string ?user=alice&age=30, the addParam() command will retrieve the value "alice" associated with the key "user" and store it in the userName variable. The userName variable will be returned through addResult(userName), resulting in the following output:

"alice"
