使用Swift发布POST请求_course

<div class="post-text" itemprop="text"> <p>I'm trying to send data over from my iOS app to a PHP script. I have Title, Description and City. I want it to always save every info I send to it from my iOS app and always make a new one every time I send it data. The problem I'm having is, when I go to the PHP file on my browser, nothing shows up. The title, description and city field is always blank. But in my Xcode console I see it returning everything correctly. Here's my swift code. </p> <pre><code>func postToServerFunction() { var url: NSURL = NSURL(string: "http://vittletest.netii.net/index.php")! var request:NSMutableURLRequest = NSMutableURLRequest(URL:url) request.HTTPMethod = "POST" let postString = "title=testing&amp;description=hello&amp;city=RanchoCordova" request.HTTPBody = postString.dataUsingEncoding(NSUTF8StringEncoding) let task = NSURLSession.sharedSession().dataTaskWithRequest(request) { data, response, error in if error != nil { println("error=\(error)") return } println("response = \(response)") let responseString = NSString(data: data, encoding: NSUTF8StringEncoding) println("responseString = \(responseString)") } task.resume() } </code></pre> <p>And here's my PHP file. </p> <pre><code>&lt;?php $something = "Some Info"; echo $something; $title = $_POST['title']; $description = $_POST['description']; $city = $_POST['city']; echo "&lt;br /&gt;"; echo "Title: ". $title; echo "&lt;br /&gt;"; echo "Description: ". $description; echo "&lt;br /&gt;"; echo "City: ". $city; ?&gt; </code></pre> <p>And here's my console output on Xcode. </p> <pre><code>2015-01-03 10:05:50.861 VittleTest[616:28516] Warning: A long-running operation is being executed on the main thread. Break on warnBlockingOperationOnMainThread() to debug. response = &lt;NSHTTPURLResponse: 0x7f9f5ae5e3f0&gt; { URL: http://vittletest.netii.net/index.php } { status code: 200, headers { Connection = close; "Content-Length" = 309; "Content-Type" = "text/html"; Date = "Sat, 03 Jan 2015 18:05:52 GMT"; Server = Apache; "X-Powered-By" = "PHP/5.2.17"; } } responseString = Optional(&lt;html&gt; &lt;head&gt; &lt;title&gt;PHP Test&lt;/title&gt; &lt;/head&gt; &lt;body&gt; Some Info&lt;br /&gt;Title: testing&lt;br /&gt;Description: hello&lt;br /&gt;City: RanchoCordova &lt;/body&gt; &lt;/html&gt; &lt;!-- Hosting24 Analytics Code --&gt; &lt;script type="text/javascript" src="http://stats.hosting24.com/count.php"&gt;&lt;/script&gt; &lt;!-- End Of Analytics Code --&gt; ) </code></pre> <p>I hope I gave you guys enough info to help me out because I can't seem to figure it out since I'm not the best with PHP.</p> </div>

在Swift 4中发出HTTP POST请求_course

<div class="post-text" itemprop="text"> <p>I´m trying to send data to a PHP file on my server using <code>URLSession</code>. This seems to fail though, since no data is received on the server.
