Pass array as parameter key in Swift using Alamofire

Question

I am trying to pass array as key in the parameter but i am getting below error:

The underlying encoder failed with the error: invalidRootObject("array([Alamofire.URLEncodedFormComponent.array([Alamofire.URLEncodedFormComponent.string("link")]), Alamofire.URLEncodedFormComponent.string("24")])")

Here is my code for parameter:

      let parameters: [[String]: String] = [
        ["link"]: linkId
    ]

Answer 1

URLEncoding handles by default the Array type as a value of a Dictionary in parameters (not as a key like in your example code) It even adds the brackets in the key by default.

So, something like this should work fine:

let parameters: [String: Any] = [
    "links": [84, 11, 83, 24]
]
AF.request(url, method: .put, parameters: parameters, encoding: URLEncoding.default).response { response in
    // ...
}
