Question

我遇到以下代码的问题，它适用于iphone 5s模拟器。但是当我连接我的iphone5s设备时，它不起作用。通过模拟器，我从swiftupload.php获得了这个（如预期的那样）

Button pressed <- swift
responseString = Optional({"message":"some variable"}Success) <- from php
Email has ben sent <- swift

随着我的设备连接，我得到了

Button pressed
responseString = Optional()

php文件看起来像：

$postdata = json_decode(file_get_contents("php://input"), TRUE);

$message = $postdata["data"];

// Store values in an array
$returnValue = array("message" => $message);

// Send back request in JSON format
echo json_encode($returnValue);

这是swift中的功能

    func postToServerFunction(){

    // json php
    let request = NSMutableURLRequest(URL: NSURL(string: "http://localhost/mydomain.com/swiftupload.php")!)
    let session = NSURLSession.sharedSession()
    request.HTTPMethod = "POST"

    let params = ["data":"some variable"] as Dictionary<String, String>
    request.HTTPBody = try! NSJSONSerialization.dataWithJSONObject(params, options: [])

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

    let task = session.dataTaskWithRequest(request, completionHandler: {data, response, error -> Void in
        //Response print

        let responseString = NSString(data: data!, encoding: NSUTF8StringEncoding)
        print("responseString = \(responseString)")

        if let HTTPResponse = response as? NSHTTPURLResponse {
            let statusCode = HTTPResponse.statusCode

            if statusCode == 200{
                print("Email has ben sent")
            }
        }
    })
    task.resume()

    print("Button pressed")
}

在iPhone上， localhost 是iPhone的IP。将“ localhost ”替换为MAC / PC的IP并检查应用传输安全性异常https://stackoverflow.com/a/30732693/4755417

Swift到本地服务器上的php无法在我的设备上运行？
