需要您的帮助，IOS Swift将数据发布到Json Alamofire [英] Need your help, IOS Swift Post data to Json Alamofire

问题描述

我有一个textlbabelfield，可通过JSon从外部数据库中获取数据。现在，我想让我的用户修改该字段并将其发布到数据库中。但同样，它不起作用，数据库没有更改。请您检查一下我的代码：

I have a textlbabelfield in which I get data from my external database through JSon. Now, I would like to let my user to modify this field and post it to the database. But again, it doesn't work, the database did not change. Please could you review my code:

PHP代码：

       <?php
/* include db.config.php */
include_once("config.php");
// Get user id
$username = isset($_POST['username']) ? mysql_real_escape_string($_POST['username']) : "";
$data = isset($_POST['signature']) ? mysql_real_escape_string($_POST['signature']) : "";

// get user data
mysql_query('SET NAMES "utf8"');
$sql = mysql_query("UPDATE users SET signature = '$data' WHERE username='$username'");

die;
mysql_close($conn);
/* JSON Response */

?>

Alamofire发布功能：

Alamofire post func:

    @IBAction func Signature(sender: UIButton) {
        var signaturesave1 = self.signature
        let prefs:NSUserDefaults = NSUserDefaults.standardUserDefaults()
        var username = prefs.valueForKey("USERNAME") as NSString
        //load and parse the JSON into an array
        Alamofire.request(.POST, "http://mywebsite/app/data/jsonsavesignature.php", parameters: ["username": username, "signature":signaturesave1]).responseJSON { (request, response, data, error) in
            if (error != nil)
            {
                // got an error in getting the data, need to handle it
                println("error calling GET usersdata")
                println(error)
            }
            else {

        self.performSegueWithIdentifier("signature_to_persoinfo", sender: self)
    }

        }
}

我得到了答案，感谢Karthikeyani的帮助，我将答案发布给了大家：

I got the answer, thanks to Karthikeyani for your help, I post the answer to share with everyone:

我的PHP脚本：

 <?php

/* include db.config.php */
include_once("config.php");
// Get user id
$username = isset($_POST['username']) ? mysql_real_escape_string($_POST['username']) : "";
$data = isset($_POST['signature']) ? mysql_real_escape_string($_POST['signature']) : "";

// get user data
mysql_query('SET NAMES "utf8"');
$sql = mysql_query("UPDATE users SET signature = '$data' WHERE username='$username'");

mysql_close($conn);
/* JSON Response */

?>

我的Alamofire发布请求：

my Alamofire post request:

  @IBAction func Signature(sender: UIButton) {
        var signaturesave1 = self.signature.text
        let prefs:NSUserDefaults = NSUserDefaults.standardUserDefaults()
        var username = prefs.valueForKey("USERNAME") as NSString
        let parameters =
            ["username": username, "signature":signaturesave1]

        //load and parse the JSON into an array
        Alamofire.request(.POST, "http://mywebsite.com/app/data/jsonsavesignature.php", parameters: parameters).responseJSON { (request, response, data, error) in

                 self.performSegueWithIdentifier("signature_to_persoinfo", sender: self)

        }
    }
