1、swift带报文的网络请求

static func request_object(method:String,url:String,bodyStr:NSString,callback:(data:NSData!,resopnse:NSURLResponse!,error:NSError!)->Void){
            let session = NSURLSession.sharedSession();
            let request = NSMutableURLRequest(URL: NSURL(string: url)!);
            request.HTTPMethod = method;
            request.HTTPBody = bodyStr.dataUsingEncoding(NSUTF8StringEncoding);
            let task = session.dataTaskWithRequest(request,completionHandler:
                {(data,response,error) -> Void in
                    callback(data: data,resopnse: response,error: error);
                }
            )
            task.resume();
    }

static func request_news_info(Params:Array<AnyObject>,error:NSError!)->Void){
        var params_dictionary = Dictionary<String,AnyObject>();
        params_dictionary["Token"] = token;
        params_dictionary["Task"] = "1";
        params_dictionary["Module"] = "7";
        params_dictionary["Params"] = Params;
        do{
            let data = try NSJSONSerialization.dataWithJSONObject(params_dictionary,options: NSJSONWritingOptions.PrettyPrinted)
            let strJson=NSString(data: data,encoding: NSUTF8StringEncoding)
            NetWork.request_object("POST",url: request_url,bodyStr: strJson!) { (data,resopnse,error) -> Void in
                callback(data: data,resopnse: resopnse,error: error)
            }
        }catch{
            print("Error");
            callback(data: nil,resopnse: nil,error: nil)
        }
        
    }

        let array = Array<AnyObject>();
        RequestData.request_news_info(array,callback: { (data,error) -> Void in
            let string = NSString.init(data:data,encoding:NSUTF8StringEncoding);
            print(string);
        })
