I am attempting to perform an alamofire post request in swift func checkIfUserExistsInDB(userName: String) -> NSString { print ("IN") var info: NSString = "" Alamofire.request(.POST, "http://blablabla.com/getuserdata", parameters: ["queryValue": userName,], encoding:.JSON).responseJSON { request, response, result in switch result { case .Success(let JSON): info = NSString(data: JSON.dataUsingEncoding(NSUTF8StringEncoding)!, encoding: NSUTF8StringEncoding)! case .Failure(let data, _): print ("IN") if let data = data { info = (NSString(data: data, encoding: NSUTF8StringEncoding)!) print (info) }

I am creating a front end in AngularJS for a backend in node.js. I have the option of two simple node.js front end servers to serve the front end web page: one is a simple app.get in express, the other is using the http-server package. Whichever front end server code I use, I get the following browser console message in Chrome: Synchronous XMLHttpRequest on the main thread is deprecated because of its detrimental effects to the end user's experience. For more help, check http://xhr.spec.whatwg.org/ . To make sure that this was not caused by anything Angular (or Bootstrap) I have cut back my

In a classes are some methods that are run synchronously. I would like them to run asynchronously, the first idea was to wrap it, and use switch enum to decide which function should be called.

If I insert a sleep there if(Test-Path -Path $OUT) { Remove-Item $OUT -Recurse Start-Sleep -s 1 } New-Item -ItemType directory -Path $OUT then it works always. How can I force Remove-Item to ensure that the folder

I'm a little new to objective-C but have run across a problem that I can't solve, mostly because I'm not sure I am implementing the solution correctly. I am trying to connect using a Synchronous Connection to a https site with a self-signed certificate. I am getting the Error Domain=NSURLErrorDomain Code=-1202 "untrusted server certificate" Error that I have seen some solutions to on this forum. The solution i found was to add: - (BOOL)connection:(NSURLConnection *)connection canAuthenticateAgainstProtectionSpace:(NSURLProtectionSpace *)protectionSpace { return [protectionSpace
