我正在尝试使用
swift获取
JSON响应.
我嗅到请求和响应 – >一切还好
但是返回值总是为零.

let httpClient = AppDelegate.appDelegate().httpRequestOperationManager as AFHTTPRequestOperationManager; let path = "/daten/wfs"; let query = "?service=WFS&request=GetFeature&version=1.1.0&typeName=ogdwien:AMPELOGD&srsName=EPSG:4326&outputFormat=json".stringByAddingPercentEscapesUsingEncoding(NSUTF8StringEncoding); func successBlock(operation: AFHTTPRequestOperation!,responSEObject: AnyObject!) { println("JSON: " + "\(responSEObject)") } func errorBlock(operation: AFHTTPRequestOperation!,error:NSError!) { println("Error: " + error.localizedDescription) } let urlString = "\(path)" + "/" + "\(query)" println("urlString: " + httpClient.baseURL.absoluteString + urlString)
我也试过这样:
httpClient.GET(urlString,parameters: nil,success: { (operation: AFHTTPRequestOperation!,responSEObject: AnyObject!) -> Void in println("Success") println("JSON: " + "\(responSEObject)") },failure:{ (operation: AFHTTPRequestOperation!,error:NSError!) -> Void in println("Failure") })
…但是responSEObject总是似乎为零

也许原因是我的AppDelegate中可能出错的初始化:
var httpRequestOperationManager: AFHTTPRequestOperationManager? // JAVA SERVER Client class func appDelegate() -> AppDelegate { return UIApplication.sharedApplication().delegate as AppDelegate } func configureWebservice() { let requestSerializer = AFJSONRequestSerializer() requestSerializer.setValue("1234567890",forHTTPHeaderField: "clientId") requestSerializer.setValue("Test",forHTTPHeaderField: "appName") requestSerializer.setValue("1.0.0",forHTTPHeaderField: "appVersion") let responseSerializer = AFJSONResponseSerializer() AFNetworkActivityIndicatorManager.sharedManager().enabled = true // ##### HTTP ##### let baseURL = NSURL(string: "http://data.wien.gv.at"); httpRequestOperationManager = AFHTTPRequestOperationManager(baseURL: baseURL)) httpRequestOperationManager!.requestSerializer = requestSerializer httpRequestOperationManager!.responseSerializer = responseSerializer }
任何建议我做错了什么?
