# percentEncodedQuery

The query URL component expressed as a URL-encoded string, or nil if not present.

## Declaration

```swift
var percentEncodedQuery: String? { get set }
```

## Discussion

Discussion For example, in the URL http://www.example.com/index.php?key1=value1&key2=value2, the query string is key1=value1&key2=value2. If you set this value to something that is not a valid, percent-encoded string, this class throws an exception.
