用Alamofire发布请求

Question

Hi I'm trying to make a post request with Alamofire using instructions from GitHub. Could somebody tell me what's wrong with my code, because new data doesn't appear in json ? Here is my VC code.

import UIKit
import Alamofire

class ViewController: UIViewController {

private struct Constants {

    static let jsonURL3 = "https://jsonblob.com/api/jsonBlob/f31670d2-11bf-11e8-8318-7b18a50c9bd0"
}

override func viewDidLoad() {
    super.viewDidLoad()
    let params = [
        "firstname": "Ivan",
        "lastname": "Nikulin"
    ]

    Alamofire.request(Constants.jsonURL3, method: .post, parameters: params)

}

}

Answer 1

You need to add the responseJSON for your call, you have only done the first part:

Alamofire.request(Constants.jsonURL3, method: .get, parameters: params).responseJSON { response in
    print(response.result.value)
}

Secondly this is a get request, so change method from post to get (as I have done in my example).

This will print out the following:

Optional(<__NSArrayI 0x60c0008371a0>(
{
    firstname = Leo;
    lastname = Messi;
},
{
    firstname = Cristiano;
    lastname = Ronaldo;
}
)
)

Update:
You can´t post to that URL, you´ll get 405 Method Not Allowed . If you want to post values you need to create/find an API or URL that allow that, that link is not for that purpose.

Answer 2

You created a request object of type DataRequest but did not fire it. You need to call responseJSON on that object to get a response. Here is example from your code

let request = Alamofire.request(Constants.jsonURL3, method: .post, parameters: params)
request.responseJSON { (response) in
    print(response.result.value)
}
