在Alamofire请求的正文中发送JSON数据

Question

I'm trying to make an api call to submit some data using Alamofire (version 4.0). I think the request has succeed. But the trouble i'm having is that when making the call I get a response from the server that 0 byte FAILURE.

I have tried many of the solutions currently on StackOverflow and cannot find a solution. Thanks for your help.

Here is my Postman setup:

My Swift code:

import UIKit
import Alamofire

class ViewController: UIViewController {

    override func viewDidLoad() {
        super.viewDidLoad()

        let headers: HTTPHeaders = [ "content-type": "x-www-form-urlencoded"]


        Alamofire.request("myurl.php?method=GET_RECENT", headers: headers).responseJSON { response in
            debugPrint(response)
            print(response.request)  // original URL request
            print(response.response) // HTTP URL response
            print(response.data)     // server data
            print(response.result)   // result of response serialization

            if let JSON = response.result.value {
                print("JSON: \(JSON)")
            }
        }

    }
}

The error I'm getting is:

[Request]: myurl.php?method=GET_RECENT [Response]: { URL: myurl.php?method=GET_RECENT } { status code: 200, headers { "Cache-Control" = "max-age=0"; Connection = "Keep-Alive"; "Content-Length" = 0; "Content-Type" = "text/html; charset=UTF-8"; Date = "Sun, 01 Jan 2017 11:41:31 GMT"; Expires = "Sun, 01 Jan 2017 11:41:31 GMT"; "Keep-Alive" = "timeout=7, max=100"; Server = "Apache/2.2.15 (CentOS)"; "X-Powered-By" = "PHP/5.6.25"; } } [Data]: 0 bytes [Result]: FAILURE: responseSerializationFailed(Alamofire.AFError.ResponseSerializationFailureReason.inputDataNilOrZeroLength) [Timeline]: Timeline: { "Request Start Time": 504963459.698, "Initial Response Time": 504963459.821, "Request Completed Time": 504963459.821, "Serialization Completed Time": 504963459.821, "Latency": 0.123 secs, "Request Duration": 0.123 secs, "Serialization Duration": 0.001 secs, "Total Duration": 0.124 secs } Optional(myurl.php?method=GET_RECENT) Optional( { URL: myurl.php?method=GET_RECENT } { status code: 200, headers { "Cache-Control" = "max-age=0"; Connection = "Keep-Alive"; "Content-Length" = 0; "Content-Type" = "text/html; charset=UTF-8"; Date = "Sun, 01 Jan 2017 11:41:31 GMT"; Expires = "Sun, 01 Jan 2017 11:41:31 GMT"; "Keep-Alive" = "timeout=7, max=100"; Server = "Apache/2.2.15 (CentOS)"; "X-Powered-By" = "PHP/5.6.25"; } }) Optional(0 bytes) FAILURE

I think you are setting your Postman setup is invalid. To send JSON as data in your GET request your should be using raw options, like on the picture below.
