Alamofire Get JSON Request and Response

Question

I am trying to use the Yoda API and send a request using the Alamofire Fast structure. I know that the API works correctly since I tested the endpoint using the Mashape API key several times. I also see that requests are being sent (Mashape homepage on my request). However, my JSON response is always nil .

 func handleRequest(words:String){ var saying = words.stringByReplacingOccurrencesOfString(" ", withString: "+"); saying = "?sentence=" + saying; let url = NSURL(string: (baseURL+saying)); println(url); var response:String; Alamofire.Manager.sharedInstance.session.configuration.HTTPAdditionalHeaders = additionalHeaders; Alamofire.request(.GET, url!).responseJSON { (_, _, JSON, _) in println(JSON); } } 

The words string could be “This is my first sentence” and it will automatically replace the spaces “+” according to the API specification. Please ignore multiple println statements, they are for debugging only.

This is just a proof of conceptual code; it is intentionally not made by many errors, and not very for this reason. If you have any suggestions, I would appreciate it.

For some reason, the problem is with the Alamofire request for JSON. This is how I handle JSON requests using Alamofire:

 Alamofire.request(.GET, urlTo, parameters: nil, encoding: .URL).responseString(completionHandler: { (request: NSURLRequest, response: NSHTTPURLResponse?, responseBody: String?, error: NSError?) -> Void in // Convert the response to NSData to handle with SwiftyJSON if let data = (responseBody as NSString).dataUsingEncoding(NSUTF8StringEncoding) { let json = JSON(data: data) println(json) } }) 

I highly recommend you use SwiftyJSON to manage JSON better and easier, it is up to you.

Hope this helps you.

An Alamofire request has several methods for responding to processing. Try processing the data and converting it to String. Confirm that the JSON response is normal.

 Alamofire.request(.GET, url!).response { (_, _, data, error) in let str = NSString(data: data, encoding: NSUTF8StringEncoding) println(str) println(error) } 

Also validation error while parsing JSON data.
