终于我做到了:)
我改变了下面的方法，它工作了
func callRequestAPI(url:String){ var configuration = NSURLSessionConfiguration.defaultSessionConfiguration() var session = NSURLSession(configuration: configuration) let params:[String: AnyObject] = [ "product_id" : selectedUberProductId, "start_latitude" : start_lat, "start_longitude" : start_lng, "end_latitude" : end_lat, "end_longitude" : end_lng] let request = appDelegate.oauth.request(forURL: NSURL(string:url)!) request.setValue("application/json; charset=utf-8", forHTTPHeaderField: "Content-Type") request.HTTPMethod = "POST" var err: NSError? request.HTTPBody = NSJSONSerialization.dataWithJSonObject(params, options: NSJSONWritingOptions.allZeros, error: &err) let task = session.dataTaskWithRequest(request) { data, response, error in if let httpResponse = response as? NSHTTPURLResponse { if httpResponse.statusCode != 202 { println("response was not 202: (response)") return } } if (error != nil) { println("error submitting request: (error)") return } // handle the data of the successful response here var result = NSJSONSerialization.JSonObjectWithData(data, options: NSJSONReadingOptions.allZeros, error: nil) as! NSDictionary println(result) if let request_id: String = result["request_id"] as? String{ println(request_id) } if let driver: String = result["driver"] as? String{ println(driver) } if let eta: Int = result["eta"] as? Int{ println(eta) } if let location: String = result["location"] as? String{ println(location) } if let status: String = result["status"] as? String{ println(status) } if let surge_multiplier: Int = result["surge_multiplier"] as? Int{ println(surge_multiplier) } if let vehicle: String = result["vehicle"] as? String{ println(vehicle) } } task.resume() }这是我得到的响应，我上面的方法也给出了解析
{ driver = "<null>"; eta = 15; location = "<null>"; "request_id" = "ea39493d-b718-429f-8710-00a34dcdaa93"; status = processing; "surge_multiplier" = 1; vehicle = "<null>";}请享用
