queryStringParameters

A query string is a part of a uniform resource locator (URL) that assigns values to certain parameters. The query string is an ordered list of key-value pairs, where each key-value pair consists of a parameter name (key) and a value. These pairs are separated by ampersands (&) and the entire query string is appended to the URL after a question mark (?).

For example, in the URL http://www.example.com/search?q=wiki&sort=asc, "q" is a key with the value "wiki", and "sort" is a key with the value "asc". The question mark separates the base URL from the query string, and the ampersand separates the key-value pairs.

Query string parameters are commonly used to pass data to a web server. This data can be used for various purposes, such as filtering search results, specifying user preferences, or tracking user behavior. When a web server receives a request with a query string, it can parse the parameters and use them to dynamically generate a response.

The format of query string parameters is not strictly defined, but the key-value pair structure separated by ampersands is the most widely adopted convention. Some systems may use different delimiters or encoding schemes for values, especially if they contain special characters. However, for general web development, adhering to the standard format ensures broader compatibility.
