AFNetworking post到後端，資料怎麼調用

 let afn = AFHTTPRequestOperationManager()             afn.POST("http://api.abc.com//index.php?s=/home/order/makeorder.html",parameters:            ["data":"22222"], success: { (operation: AFHTTPRequestOperation!,            responseObject: AnyObject!) in            print("%@", operation.request.allHTTPHeaderFields);            let data = responseObject as! NSDictionary!            print("擷取資料==%@",data)            if data != nil {                //   let dict: NSDictionary = (try! NSJSONSerialization.JSONObjectWithData(data!, options: .AllowFragments)) as! NSDictionary              //  let modelTool = DictModelManager.sharedManager              //  let data = modelTool.objectWithDictionary(data, cls: FreshHot.self) as? FreshHot                               // completion(data: data, error: nil)            }            },                failure: { (operation: AFHTTPRequestOperation!,                    error: NSError!) in                    //Handle Error                    print("擷取資料出錯=%@",error);        })

後台用php 拿到的$_POST 資料為

a:1:{s:4:"data";s:5:"22222";}

試著對$_Post unserialize，可是得不到資料，，

file_get_contents('php://input') 得到的的資料是

s:10:"data=22222";

請問PHP 改怎麼處理AFNetworking post過來的資料？

回複內容：
