Using the following Sinatra app
get '/app' do
content_type :json
{"params" => params}.to_json
end
Invoking:
/app?param1=one¶m2=two¶m2=alt
Gives the following result:
{"params":{"param1":"one","param2":"alt"}}
Params has only two keys, param1 & param2.
I understand Sinatra is setting params as a hash, but it does not represent all of the URL request.
Is there a way in Sinatra to get a list of all URL parameters sent in the request?

The parameters from a URL string can be retrieved in PHP using parse_url() and parse_str() functions. Note: Page URL and the parameters are separated by the ? character. parse_url() Function: The parse_url() function is used to return the components of a URL by parsing it.
Any word after the question mark (?) in a URL is considered to be a parameter which can hold values. The value for the corresponding parameter is given after the symbol "equals" (=). Multiple parameters can be passed through the URL by separating them with multiple "&".
Params is short for the word parameter. A parameter is a key-value pair that is encoded in a HTTP request. There are three kinds of params: user supplied parameters , routing parameters , and default parameters .
URL parameters or query string parameters are used to send a piece of data from client to server via a URL. They can contain information such as search queries, link referrals, user preferences, etc..
You can also loop through a list of key/value pairs a couple of different ways, providing additional ways to access all of your URL parameters with ease: URL parameter parsing and manipulation has never been easier, thanks to JavaScript and the URLSearchParams interface. Subscribe & Learn More!
They can contain information such as search queries, link referrals, user preferences, etc.. The URLSearchParams interface makes it easier to get the parameter of the URL. It provides methods for working with the query string of a URL.
The URLSearchParams.getAll () method returns all of the values associated with a certain parameter: The URLSearchParams interface specifies the utility methods to work with the query string of a URL. The URLSearchParams suggests a consistent interface to the pieces of the URL and allows a manipulation of the query string (what comes after "?").

get '/app' do
params = request.env['rack.request.query_hash']
