无法让 POST 请求工作 AlamoFire 和 XCode/Swift

Question

I am using Swift and Xcode and am trying to send a Post request. A normal request without parameters and no method declaration is working. However, when I try to do a specific post request with parameters it no longer works. I have taken the logic straight from Alamofire's documentation. I have included some pictures and code below.

let parameters = ["barcdodeNumber": displayValue]
            
AF.request(url, method: .post, parameters: parameters)
//this is the right way, but it does not work
            
AF.request(url).response { response in
    debugPrint(response)
}
//this is wrong but it works

Answer 1

You need to call one of the response methods, eg,

AF.request(url, method: .post, parameters: parameters).response { response in
    debugPrint(response)
}

This begs the question as to what your endpoint returns. Usually it's JSON, so you'd use responseJSON or one of the decoder renditions.

Answer 2

Ultimately this was the way that ended up working correctly.

    AF.request(url, method: .post, parameters: params, encoding: 
    URLEncoding(destination: .queryString)).response { response in
                debugPrint(response)
            }
