iOS - 如何将数组作为参数传递给AFNetworking（Objective-C）(iOS - How to pass array to AFNetworking as parameters (Objective-C))

 我有一个php文件，我想用它来处理数据。 php文件包含一个以数组作为参数的函数。 
 
 php功能： 
 
func((array)$input->foos as &$foo){
  $request = mb_strtolower($foo->request);
  $found = false;
  $loopCount = 0;
  while($found === false && $loopCount < 3){
    if($request === 'single' || $request === 'corner'){
      $foo->request = $single_priority[$loopCount];
    }
    else if($request === 'double'){
      $foo->request = $double_priority[$loopCount];
    }
    else if($request === 'quad'){
      $foo->request = $quad_priority[$loopCount];
    }

    $rooms = getRooms($foo, $link, $roomcounts[$foo->request]);
    if($room = $rooms->fetch_assoc()){
      $found = true;



      if ($loopCount === 0){
        if(!$link->query("REPLACE INTO reservations VALUES('{$room['room_id']}', '{$foo->user_id}', 
            '{$foo->move_in_date}', '{$foo->move_out_date}', 'Incoming', '{$foo->date_added}')")){
            $arr = array();
            $arr['error'] = "Error: " . $link->error;
            echo json_encode($arr);
            die();
        }

        array_push($result, array('user_id' => $foo->user_id, 'room_assigned' => $room['room_id'], 'request_status' => 0));
        if(!$link->query("DELETE FROM res_waiting WHERE user_id = '{$foo->user_id}'")){
            $arr = array();
            $arr['error'] = "Error: " . $link->error;
            echo json_encode($arr);
            die();
        }
      }
      else{
        if(!$link->query("INSERT IGNORE INTO reservations VALUES('{$room['room_id']}', '{$foo->user_id}', 
            '{$foo->move_in_date}', '{$foo->move_out_date}', 'Incoming', '{$foo->date_added}')")){
            $arr = array();
            $arr['error'] = "Error: " . $link->error;
            echo json_encode($arr);
            die();
        }

        array_push($result, array('user_id' => $foo->user_id, 'room_assigned' => $room['room_id'], 'request_status' => 1));
      }
    }

    $loopCount += 1;
  }

  if (found === false){
    array_push($result, array('user_id' => $foo->user_id, 'room_assigned' => 0, 'request_status' => 2));
  }
}
 
 我正在使用AFNetworking将php代码连接到Objective-C 
 
 Objective-C代码： 
 
-(void) connectToPHP:(NSArray *)parameters
{
    AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
    manager.requestSerializer = [AFJSONRequestSerializer serializer];
    manager.responseSerializer = [AFHTTPResponseSerializer serializer];
   NSString *URLString = [[NSString alloc] initWithFormat:@"ip.address/email.php"];
    [manager POST:URLString parameters:parameters success:^(AFHTTPRequestOperation *operation, id responseObject) {
        NSData *jsonData = responseObject;
        NSError * error=nil;
        id reponse = [NSJSONSerialization JSONObjectWithData:jsonData options:NSJSONReadingMutableContainers error:&error];
        NSLog(@"JSON response: %@", [reponse objectForKey:@"response"]);
    } failure:^(AFHTTPRequestOperation *operation, NSError *error) {
        if(error){
            NSLog(@"%@ Error:", error);
        }
    }];
}
 
 功能调用： 
 
NSDictionary *foo = @{
                      @"id" : @"2011011",
                      @"request" : @"single",
                      @"gender" : @"M",
                      @"username" : @"name",
                      };

NSArray *arr = [NSArray arrayWithObjects:foo, nil];

[self connectToPHP:arr];
 
 但是当我运行它时，php文件中的函数无法正常运行，我收到错误。 我认为这与我如何将数组作为参数传递有关。 

I have a php file which I want to use to process data. The php file contains a function that takes in an array as parameters. 
 
php function: 
 
func((array)$input->foos as &$foo){
  $request = mb_strtolower($foo->request);
  $found = false;
  $loopCount = 0;
  while($found === false && $loopCount < 3){
    if($request === 'single' || $request === 'corner'){
      $foo->request = $single_priority[$loopCount];
    }
    else if($request === 'double'){
      $foo->request = $double_priority[$loopCount];
    }
    else if($request === 'quad'){
      $foo->request = $quad_priority[$loopCount];
    }

    $rooms = getRooms($foo, $link, $roomcounts[$foo->request]);
    if($room = $rooms->fetch_assoc()){
      $found = true;



      if ($loopCount === 0){
        if(!$link->query("REPLACE INTO reservations VALUES('{$room['room_id']}', '{$foo->user_id}', 
            '{$foo->move_in_date}', '{$foo->move_out_date}', 'Incoming', '{$foo->date_added}')")){
            $arr = array();
            $arr['error'] = "Error: " . $link->error;
            echo json_encode($arr);
            die();
        }

        array_push($result, array('user_id' => $foo->user_id, 'room_assigned' => $room['room_id'], 'request_status' => 0));
        if(!$link->query("DELETE FROM res_waiting WHERE user_id = '{$foo->user_id}'")){
            $arr = array();
            $arr['error'] = "Error: " . $link->error;
            echo json_encode($arr);
            die();
        }
      }
      else{
        if(!$link->query("INSERT IGNORE INTO reservations VALUES('{$room['room_id']}', '{$foo->user_id}', 
            '{$foo->move_in_date}', '{$foo->move_out_date}', 'Incoming', '{$foo->date_added}')")){
            $arr = array();
            $arr['error'] = "Error: " . $link->error;
            echo json_encode($arr);
            die();
        }

        array_push($result, array('user_id' => $foo->user_id, 'room_assigned' => $room['room_id'], 'request_status' => 1));
      }
    }

    $loopCount += 1;
  }

  if (found === false){
    array_push($result, array('user_id' => $foo->user_id, 'room_assigned' => 0, 'request_status' => 2));
  }
}
 
I am using AFNetworking to connect to the php code to Objective-C
 
Objective-C code:
 
-(void) connectToPHP:(NSArray *)parameters
{
    AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
    manager.requestSerializer = [AFJSONRequestSerializer serializer];
    manager.responseSerializer = [AFHTTPResponseSerializer serializer];
   NSString *URLString = [[NSString alloc] initWithFormat:@"ip.address/email.php"];
    [manager POST:URLString parameters:parameters success:^(AFHTTPRequestOperation *operation, id responseObject) {
        NSData *jsonData = responseObject;
        NSError * error=nil;
        id reponse = [NSJSONSerialization JSONObjectWithData:jsonData options:NSJSONReadingMutableContainers error:&error];
        NSLog(@"JSON response: %@", [reponse objectForKey:@"response"]);
    } failure:^(AFHTTPRequestOperation *operation, NSError *error) {
        if(error){
            NSLog(@"%@ Error:", error);
        }
    }];
}
 
Function call:
 
NSDictionary *foo = @{
                      @"id" : @"2011011",
                      @"request" : @"single",
                      @"gender" : @"M",
                      @"username" : @"name",
                      };

NSArray *arr = [NSArray arrayWithObjects:foo, nil];

[self connectToPHP:arr];
 
However when I run this the function in the php file does not run correctly and I get an error. I think it has to do with how I pass the array as parameters.
