  在Swift 3中，您可以：

  let url = URL(string: "http://www.thisismylink.com/postName.php")!
  var request = URLRequest(url: url)
  request.setValue("application/x-www-form-urlencoded", forHTTPHeaderField: "Content-Type")
  request.httpMethod = "POST"
  let postString = "id=13&name=Jack"
  request.httpBody = postString.data(using: .utf8)
  let task = URLSession.shared.dataTask(with: request) { data, response, error in
      guard let data = data, error == nil else {                                                 // check for fundamental networking error
          print("error=\(error)")
          return
      }
  
      if let httpStatus = response as? HTTPURLResponse, httpStatus.statusCode != 200 {           // check for http errors
          print("statusCode should be 200, but is \(httpStatus.statusCode)")
          print("response = \(response)")
      }
  
      let responseString = String(data: data, encoding: .utf8)
      print("responseString = \(responseString)")
  }
  task.resume()
  

  这将检查基本网络错误以及高级HTTP错误 .

  Swift 3 and swift 4

  @IBAction func submitAction(sender: UIButton) {
  
      //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()
  }

  下面是我在日志库中使用的方法：https://github.com/goktugyil/QorumLogs

  此方法填写Google表单中的html表单 .

  var url = NSURL(string: urlstring)
  
      var request = NSMutableURLRequest(URL: url!)
      request.HTTPMethod = "POST"
      request.setValue("application/x-www-form-urlencoded; charset=utf-8", forHTTPHeaderField: "Content-Type")
      request.HTTPBody = postData.dataUsingEncoding(NSUTF8StringEncoding)
      var connection = NSURLConnection(request: request, delegate: nil, startImmediately: true)

  @IBAction func btn_LogIn(sender: AnyObject) {
  
      let request = NSMutableURLRequest(URL: NSURL(string: "http://demo.hackerkernel.com/ios_api/login.php")!)
      request.HTTPMethod = "POST"
      let postString = "email: test@test.com & password: testtest"
      request.HTTPBody = postString.dataUsingEncoding(NSUTF8StringEncoding)
      let task = NSURLSession.sharedSession().dataTaskWithRequest(request){data, response, error in
          guard error == nil && data != nil else{
              print("error")
              return
          }
          if let httpStatus = response as? NSHTTPURLResponse where httpStatus.statusCode != 200{
              print("statusCode should be 200, but is \(httpStatus.statusCode)")
              print("response = \(response)")
          }
          let responseString = String(data: data!, encoding: NSUTF8StringEncoding)
          print("responseString = \(responseString)")
      }
      task.resume()
  }

  let session = URLSession.shared
          let url = "http://...."
          let request = NSMutableURLRequest(url: NSURL(string: url)! as URL)
          request.httpMethod = "POST"
