在Swift中进行REST API调用

您可以这样做：

var url : String = "http://google.com?test=toto&test2=titi"var request : NSMutableURLRequest = NSMutableURLRequest()request.URL = NSURL(string: url)request.HTTPMethod = "GET"NSURLConnection.sendAsynchronousRequest(request, queue: NSOperationQueue(), completionHandler:{ (response:NSURLResponse!, data: NSData!, error: NSError!) -> Void in    var error: AutoreleasingUnsafeMutablePointer<NSError?> = nil    let jsonResult: NSDictionary! = NSJSONSerialization.JSonObjectWithData(data, options:NSJSONReadingOptions.MutableContainers, error: error) as? NSDictionary    if (jsonResult != nil) {        // process jsonResult    } else {       // couldn't load JSON, look at error    }})

编辑：对于对此有疑问的人，也许您的JSON流是数组[]而不是对象{}，因此您必须将jsonResult更改为

NSArray

而不是

NSDictionary
