我是 iOS 开发的新手。我正在尝试加载 JSON ，这是我的函数：

I am new to iOS development. I am trying to load a JSON, here's my function:

func loadmyJSON (urlPath: String) { let url: NSURL = NSURL(string: urlPath)! let session = NSURLSession.sharedSession() let task = session.dataTaskWithURL(url, completionHandler: {data, response, error -> Void in println("Task completed") if(error != nil) { // If there is an error in the web request, print it to the console println("error not nil::::::") println(error.localizedDescription) } var err: NSError? var jsonResult = NSJSONSerialization.JSONObjectWithData(data, options: NSJSONReadingOptions.MutableContainers, error: &err) as NSDictionary if(err != nil) { // If there is an error parsing JSON, print it to the console println("JSON Error \(err!.localizedDescription)") } let results: NSArray = jsonResult["variants"] as NSArray dispatch_async(dispatch_get_main_queue(), { self.jsonTable = results self.productView!.reloadData() }) })

但我收到此错误：

error not nil:::::: The operation couldn’t be completed. (NSURLErrorDomain error -1002.)

我能够通过相同的URL在浏览器中获取JSON。 我试过阅读这个：但是我无法获得描述。

I am able to get the JSON in browser through the same URL. I have tried reading THIS: but I can't get the description.

这个错误代码是什么意思？

What does this error code mean?

推荐答案

NSURLErrorDomain错误-1002 表示 NSURLErrorUnsupportedURL 或 kCFURLErrorUnsupportedURL 。它表示在大多数情况下提供了错误的URL，从URL前缀中缺少 http：// 。

NSURLErrorDomain error -1002 means NSURLErrorUnsupportedURL or kCFURLErrorUnsupportedURL. It indicates that a bad URL was provided, in most cases, missing from the URL prefix.
