स्विफ्ट 3

@IBAction func submitAction(sender: AnyObject) {

    //declare parameter as a dictionary which contains string as key and value combination. considering inputs are valid

    let parameters = ["id": 13, "name": "jack"]

    //create the url with URL
    let url = URL(string: "www.thisismylink.com/postName.php")! //change the url

    //create the session object
    let session = URLSession.shared

    //now create the URLRequest object using the url object
    var request = URLRequest(url: url)
    request.httpMethod = "POST" //set http method as POST

    do {
        request.httpBody = try JSONSerialization.data(withJSONObject: parameters, options: .prettyPrinted) // pass dictionary to nsdata object and set it as request body
    } catch let error {
        print(error.localizedDescription)
    }

    request.addValue("application/json", forHTTPHeaderField: "Content-Type")
    request.addValue("application/json", forHTTPHeaderField: "Accept")

    //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
        }

        do {
            //create json object from data
            if let json = try JSONSerialization.jsonObject(with: data, options: .mutableContainers) as? [String: Any] {
                print(json)
                // handle json...
            }
        } catch let error {
            print(error.localizedDescription)
        }
    })
    task.resume()
}
Question

मैं एक यूआरएल को पोस्ट 2 पैरामीटर पोस्ट करने के लिए स्विफ्ट में एक HTTP अनुरोध चलाने की कोशिश कर रहा हूं।

उदाहरण:

लिंक: www.thisismylink.com/postName.php

पैरामीटर:

id = 13
name = Jack

ऐसा करने का सबसे आसान तरीका क्या है?

मैं प्रतिक्रिया भी पढ़ना नहीं चाहता हूं। मैं बस एक PHP फ़ाइल के माध्यम से अपने डेटाबेस पर परिवर्तन करने के लिए भेजना चाहता हूँ।
