代码

    let session = URLSession.shared

    // prepare json data
    let json: [String: Any] = ["email": "test_mobile@mysite.com"]

    let jsonData = try? JSONSerialization.data(withJSONObject: json)

    let proceedURL = NSURL(string:"https://mysitename.herokuapp.com/api/users/isUser")
    //let proceedURL = NSURL(string:"https://google.com")
    let request = NSMutableURLRequest(url: proceedURL! as URL)
    //HTTP Headers
    request.addValue("application/json", forHTTPHeaderField: "Content-Type")
    request.addValue("application/www.inception.v1", forHTTPHeaderField: "Accept")
    request.addValue("Authorization", forHTTPHeaderField: "Basic aW5jZXB0aW9uQGZ1cmRvOmljM=")
    request.httpMethod = "POST"
    //request.httpBody = jsonData


    // insert json data to the request
    request.httpBody = jsonData

    //create dataTask using the session object to send data to the server
    let task = session.dataTask(with: request as URLRequest, completionHandler: { data, response, error in

        guard error == nil else {
            return
        }

        guard let data = data else {
            return
        }

        // Print out response string
        let responseString = NSString(data: data, encoding: String.Encoding.utf8.rawValue)
        print("responseString = \(responseString!)")

        do {
            //create json object from data
            if let json = try JSONSerialization.jsonObject(with: data, options: .mutableContainers) as? [String: AnyObject] {
                print(json)
                // handle json...
            }

        } catch let error {
            print("error : " + error.localizedDescription)
        }

    })

    task.resume()

错误: 无法读取数据，因为它的格式不正确。

我是 iphone 应用程序开发的初学者，请帮助我并为建立网络连接提供更好的建议(就像在 android 中我正在使用 Volley 库)

实际响应是:

{
  "status": 1,
  "http_status_code": 200,
  "data": {
    "email": "test_mobile@mysite.com",
    "phone": "8090909000"
  }
}

我在 Android 上使用相同的东西并在 postman 中进行测试。

// Print out response string
        let responseString = NSString(data: data, encoding: String.Encoding.utf8.rawValue)

对于上层代码响应什么都没有

最佳答案

使用 Alamofire。

let json: [String: Any] = ["email": "test_mobile@mysite.com"]

Alamofire.request(.POST, "https://mysitename.herokuapp.com/api/users/isUser" , parameters: json, encoding:  .JSON).responseJSON {
            Response in
            switch Response.result {
            case .Success(let _data):
                let JsonData = JSON(_data)
                print("JsonData : \(JsonData)")


           //handle json


case .Failure(let _error):
                print(_error)
                let AlertBox = UIAlertController(title: "Connection Failed", message: "No Connection", preferredStyle: .Alert)
                let ActionBox = UIAlertAction(title: "Ok" , style: .Default, handler: { _ in})
                AlertBox.addAction(ActionBox)
                self.presentViewController(AlertBox, animated: true, completion: nil)
            }
