How to pass parameters to RxAlamofire requestJSON method

Answer 1

You need to construct the URL from URLComponents.

var components = URLComponents(string: "https://www.example.com/path")!
components.queryItems = [
    .init(name: "param1", value: "value1"),
    .init(name: "param2", value: "value2"),
]

let url = components.url!

The url above will be

https://www.example.com/path?param1=value1&param2=value2

The use of ! should not be problematic above as the data you are passing should be valid. Please refer to the documentation of these methods though to assess the requirement for proper nil handling.
