从Swift到php脚本的Http post请求 require("Conn.php"); require("MySQLDao.php"); $name=htmlentities($_POST["name"]); $email=htmlentities($_POST["email"]); $password=htmlentities($_POST["password"]); $returnValue = array(); if(empty($email) || empty($password)) { $returnValue["status"] = "error"; $returnValue["message"] = "Missing required field"; echo json_encode($returnValue); return; } $dao = new MySQLDao(); $dao->openConnection(); $userDetails = $dao->getUserDetails($email); if(!empty($userDetails)) { $returnValue["status"] = "error"; $returnValue["message"] = "User already exists"; echo json_encode($returnValue); return; } $secure_password = md5($password); $result = $dao->registerUser($name, $email, $secure_password); if($result) { $returnValue["status"] = "Success"; $returnValue["message"] = "User is registered"; echo json_encode($returnValue); return; } $dao->closeConnection();

我有一个php脚本名UserRegister.php。在这个脚本中，我有一些Post变量。这些变量来自我的iOS应用程序，然后脚本应该将其保存到我的mysql数据库中

require("Conn.php");
require("MySQLDao.php");

$name=htmlentities($_POST["name"]);
$email=htmlentities($_POST["email"]);
$password=htmlentities($_POST["password"]);

$returnValue = array();

if(empty($email) || empty($password))
{
    $returnValue["status"] = "error";
    $returnValue["message"] = "Missing required field";
    echo json_encode($returnValue);
    return;

}

$dao = new MySQLDao();
$dao->openConnection();
$userDetails = $dao->getUserDetails($email);

if(!empty($userDetails))
{
    $returnValue["status"] = "error";
    $returnValue["message"] = "User already exists";
    echo json_encode($returnValue);
    return;

}

$secure_password = md5($password);

$result = $dao->registerUser($name, $email, $secure_password);

if($result)
{
    $returnValue["status"] = "Success";
    $returnValue["message"] = "User is registered";
    echo json_encode($returnValue);
    return;
}

$dao->closeConnection();

my.php脚本

require("Conn.php");
require("MySQLDao.php");

$name=htmlentities($_POST["name"]);
$email=htmlentities($_POST["email"]);
$password=htmlentities($_POST["password"]);

$returnValue = array();

if(empty($email) || empty($password))
{
    $returnValue["status"] = "error";
    $returnValue["message"] = "Missing required field";
    echo json_encode($returnValue);
    return;

}

$dao = new MySQLDao();
$dao->openConnection();
$userDetails = $dao->getUserDetails($email);

if(!empty($userDetails))
{
    $returnValue["status"] = "error";
    $returnValue["message"] = "User already exists";
    echo json_encode($returnValue);
    return;

}

$secure_password = md5($password);

$result = $dao->registerUser($name, $email, $secure_password);

if($result)
{
    $returnValue["status"] = "Success";
    $returnValue["message"] = "User is registered";
    echo json_encode($returnValue);
    return;
}

$dao->closeConnection();

我的swift密码

//Store data
    //Send user data to server side
    let myURL: NSURL! = NSURL(string: "http://localhost:8888/iOSDatabase/UserRegister.php")
    let request: NSMutableURLRequest = NSMutableURLRequest(URL: myURL!)
    request.HTTPMethod = "POST"

    let postString = "name=" + UserName + "&email=" + UserEmail + "&password=" + UserPassword
    println(postString)

    request.HTTPBody = postString.dataUsingEncoding(NSUTF8StringEncoding)

    let task = NSURLSession.sharedSession().dataTaskWithRequest(request) {
        data, response, error in

        println("response =\(response)")

        if error != nil {
            println("error=\(error)")
            return
        }

        var responseString = NSString(data: data, encoding: NSUTF8StringEncoding)
        println("responseString =\(responseString)")

        var err: NSError?

        if var json: NSDictionary = NSJSONSerialization.JSONObjectWithData(data, options: .MutableContainers, error: &err) as? NSDictionary {
            if error == nil
            {
                println(json)

            }
        }
    }

    task.resume()

我打印出我的响应，得到状态代码：500，在我的标题中显示Connection=close。它不会将任何JSON文件返回到我的iOS应用程序。

您使用PHP的

$\u POST

命令检索变量，但使用Swift中的GET请求发送变量。您可以在Swift中使用

request.HTTPMethod=“GET”

更改请求类型，或者在PHP中使用

$\u GET

500=内部服务器错误。您需要检查服务器的错误日志以获取详细信息。@MarcB如何或在哪里可以获得此服务器的错误日志？不知道。您必须查看php服务器的配置。如果是LinuxISH，它可能是

/var/log/httpd/error\u log

或类似的东西。
