Question

我被困在Swift项目中。我打电话给＃34; SendPost＆＃34;从按钮IBAction我需要它返回Alamofire.request的数据，但我不知道如何达到这个。我无法进入＆＃34; utf8Text＆＃34;来自Alamofire.request的变量。我怎样才能获得数据？

谢谢。：）

import Foundation
import Alamofire


  func SendPost(parameters: Parameters) -> String {

  Alamofire.request("https://hovnocuc.com/main.php", method: .post, parameters: parameters).response { response in
        print("Request: \(response.request)")
        print("Response: \(response.response)")
        print("Error: \(response.error)")

        if let data = response.data, let utf8Text = String(data: data, encoding: .utf8) {
            print("Data: \(utf8Text)")

        }
    }

 return "I don't know. :(";
 }

适用于Swift 3

使用完成来返回从Request：

获得的de数据

首先创建一个typealias，用作闭包：

typealias SendPostCompletion = (_ data: String) -> Void

然后：

@IBAction func yourAction(_ sender: UIButton) {
        SendPost(parameters: ...) { (data) in
            print(data)
        }
}

func SendPost(parameters: Parameters, completion: @escaping SendPostCompletion) -> String {

        Alamofire.request("https://hovnocuc.com/main.php", method: .post, parameters: parameters).response { response in
            print("Request: \(response.request)")
            print("Response: \(response.response)")
            print("Error: \(response.error)")

            if let data = response.data, let utf8Text = String(data: data, encoding: .utf8) {
                var data = ("Data: \(utf8Text)")
                completion(data)
            }
        }

        completion("I don't know. :(")
}

希望它可以帮到你！

尝试使用以下代码

func SendPost(parameters: Parameters) -> [String,AnyObject] {

       let urlstring= "https://hovnocuc.com/main.php" 
       Alamofire.request(.POST, urlstring, parameters: parameters, encoding: .JSON).responseJSON { response in

                       if let JSON = response.result.value {
                           print("JSON: \(JSON)")
                           return JSON 
                       }
                   }
               return "I don't know "
            }
