## 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"` .
|
|
|
|
```javascript
|
|
// 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:
|
|
|
|
```javascript
|
|
"alice"
|
|
```
