GET可以直接在地址中传入参数，但是传入的字符根据服务器限定有限。而POST则没有。

//PHP中的获取方式是POST<?php$name = $_POST['name'];if( isset($name)){    echo 'hello '.$name;}else{    echo "No Args";}?>

import UIKitclass ViewController: UIViewController {    @IBOutlet var tvout: UITextView!    @IBAction func Connectbtnpress(sender: AnyObject) {        let configuration = NSURLSessionConfiguration.defaultSessionConfiguration()        let session = NSURLSession(configuration: configuration, delegate:nil, delegateQueue:NSOperationQueue())//创建一个新的线程        //GET 方式        let request = NSURLRequest(URL: NSURL(string: "http://localhost:63342/untitled/learn.php?name=\(tvinput.text!)")!)//传入地址，参数为 tvinput.text的内容        //POST 方式        let req = NSMutableURLRequest(URL: NSURL(string: "http://localhost:63342/untitled/learn.php")!)        req.HTTPMethod = "POST"        req.HTTPBody = NSString(string: "name=\(tvinput.text!)").dataUsingEncoding(NSUTF8StringEncoding)        //GET方式与POST方式不同，同样在PHP文件中也要修改方式        let task = session.dataTaskWithRequest(req, completionHandler: { (data:NSData?, response:NSURLResponse?, error:NSError?) -> Void in            if let _ = data{                //把消息发给主线程                dispatch_sync(dispatch_get_main_queue(), { () -> Void in                self.tvout.text = (NSString(data: data!, encoding: NSUTF8StringEncoding)) as String!                })            }        })        task.resume()    }    @IBOutlet var tvinput: UITextField!    override func viewDidLoad() {        super.viewDidLoad()        // Do any additional setup after loading the view, typically from a nib.    }    override func didReceiveMemoryWarning() {        super.didReceiveMemoryWarning()        // Dispose of any resources that can be recreated.    }}
