POST 调用未将结果从 REST API 返回到 iPhone 应用程序

我在让iPhone应用程序使用我的API正确发送POST时遇到问题。进行调用时，根本不返回任何结果。

1. POST 调用旨在发送消息（存储消息，检查某些参数，并启动"推送"通知）

2. 发布调用适用于.php文件上的表单，但在通过应用程序使用时则不然。返回结果：{"消息"：{"消息"：{"已保存"：1}}，"推送"：1，"错误"：[]} 推送期间的错误是预期的，因为 test2.php 不会将消息发送到移动设备，而只是将消息发送到数据库。

3. 这是应用程序的开机自检代码

   NSDate *now = [NSDate date];
   NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];
   [dateFormatter setDateFormat:@"yyyy-MM-dd HH:mm:ss"];
   NSString *time = [dateFormatter stringFromDate:now];
   NSLog(@"time : %@", time);
   NSLog(@"message : %@", self.messageTxt.text);
   NSString *urlString = [[Utils getSendMessageUrl] stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding];
   NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:[NSURL URLWithString:urlString]];
   [request setHTTPMethod:@"POST"];
   [request setValue:[UserSession sharedInstance].customerTableNum forHTTPHeaderField:@"point"];
   [request setValue:[UserSession sharedInstance].locationId forHTTPHeaderField:@"location"];
   [request setValue:time forHTTPHeaderField:@"sent"];
   [request setValue:self.messageTxt.text forHTTPHeaderField:@"message"];
   [request setValue:[UserSession sharedInstance].phoneNumber forHTTPHeaderField:@"number"];
   self.receivedData = [NSMutableData data];
   NSURLConnection *sendConnection = [NSURLConnection connectionWithRequest:request delegate:self];
   [sendConnection scheduleInRunLoop:[NSRunLoop currentRunLoop] forMode:NSRunLoopCommonModes];
   [sendConnection start];
   

什么可能导致应用加载索引.php但没有结果？post变量设置正确，即使"push"失败，消息仍应输入数据库（就像test2.php成功一样）。

提前感谢您的任何见解。

以下是我的应用开发人员的回复：

pragma mark - NSURLConnection delegate

  (void)connection:(NSURLConnection *)connection didReceiveResponse:(NSURLResponse *)response
 {
     NSLog(@"didReceiveResponse");
     [self.receivedData setLength:0];
 }
 (void)connection:(NSURLConnection *)connection didReceiveData:(NSData *)data
 {
     NSLog(@"didReceiveData : %@", data);
     [self.receivedData appendData:data];
  }
  (void)connection:(NSURLConnection *)connection didFailWithError:(NSError *)error
 {
      NSLog(@"didFailWithError");
 }
  (void)connectionDidFinishLoading:(NSURLConnection *)connection
 {
     NSString *resultString = [[NSString alloc] initWithData:self.receivedData encoding:NSUTF8StringEncoding];
     NSLog(@"result : %@", resultS tring);
      [self performSelectorOnMainThread:@selector(didSendMessage:) withObject:resultString waitUntilDone:NO];
  }

I get the following log.
    2012-04-11 00:13:59.177 M[7682:707] didReceiveResponse
    2012-04-11 00:13:59.179 M[7682:707] result : 
    No header response is sent back.

该请求需要满足以下条件：

• 位置（数量）
• 点（数字）
数字
• （数字）
• 消息（字符串）
• 已发送（日期时间：年-月-日
。

这是一个没有安全部分的PHP代码来减少长度。

1. 处理从 case = post 开始的所有内容的调用（get 用于检索消息）

   $request = RestUtils::processRequest();
   switch ($request->getMethod()){
       case 'get':
       case 'post':
           $db = get_db();
           $response = array();
           $response["message"] = array();     
           $data = $request->getRequestVars();
           $location = htmlspecialchars($data["location"]);
           $point = htmlspecialchars($data["point"]);
           $area = get_area($point, $location, $db);
           $employee = get_employee($request, $area, $db);
           $message_id = add_message($response["message"], $request, $area, $db);      
           if($employee == false){
               $response["error"] = "mo.";
               $response["pushed"] = 0;
               RestUtils::sendResponse(410, json_encode($response), 'application/json');
               exit;
           }
           $response["pushed"] = array();
           $response["error"] = array();
           $number = htmlspecialchars($data['number']);
           switch($employee["phone_Type"]){
               case 1:
                   if(is_blocked($number)){
                       $response["error"] = "You're Number is Blocked";
                       $response["pushed"] = 0;
                       RestUtils::sendResponse(503, json_encode($response), 'application/json');
                       exit;
                   }
                   if(push_android($employee["device_ID"], $message_id, $point, $location) == false){
                       $response["error"] = "Service Temporally Unavailable";
                       $response["pushed"] = 0;
                       RestUtils::sendResponse(400, json_encode($response), 'application/json');
                       exit;
                   }
                   $response["pushed"] = 1;
                   break;
               case 2:
                   if(is_blocked($number)){
                       $response["error"] = "You're Number is Blocked";
                       $response["pushed"] = 0;
                       RestUtils::sendResponse(503, json_encode($response), 'application/json');
                       exit;
                   }
                   push_iOS($employee["device_ID"], $message_id, $point, $location);
                   $response["pushed"] = 1;
                   break;
               default:
                   $response["pushed"] = 0;
                   $response["error"] = 'Unsupported Phone Type';
                   RestUtils::sendResponse(406, json_encode($response), 'application/json');
           }
           $db->close();
           RestUtils::sendResponse(200, json_encode($response), 'application/json');
           break;
   }
   

2. 以下是支持功能：

   function build_post_query($area, $point, $location, $message, $number, $sent){
       return "INSERT INTO messages (message_ID, area_ID, point_ID, location_ID, message_Sent, message_Text, message_Number, message_Viewed) VALUES (NULL, ".$area.", ".$point.", ".$location.", '".$sent."', '".$message."', '".$number."', 0)";
   }
   function add_message(&$response, $request, $area, $db){
       $data = $request->getRequestVars();
       $point = htmlspecialchars($data["point"]);
       $location = htmlspecialchars($data["location"]);
       $area = get_area($point, $location, $db);
       $sent = htmlspecialchars($data["sent"]);// 'yyyy-mm-dd HH:mm:ss' format from users phone
       $message = htmlspecialchars($data["message"]);
       $number = htmlspecialchars($data["number"]);
       $query = build_post_query($area, $point, $location, $message, $number, $sent);
       $result = $db->query($query);
       $response["message"] = array('saved'=>$db->affected_rows);
       $message_id = $db->insert_id;
       return $message_id;
   }
   function get_area($p, $loc, $db){
       $query = "SELECT area_ID FROM points WHERE point_ID = ".$p." AND location_ID = ".$loc;
       $result = $db->query($query);
       $result = $result->fetch_assoc();
       return $result["area_ID"];
   }
   function get_employee($request, $area, $db){
       $data = $request->getRequestVars();
       $point = htmlspecialchars($data["point"]);
       $location = htmlspecialchars($data["location"]);
       $query = "SELECT device_ID, phone_Type, employee_Phone FROM active_employees WHERE area_ID = ".$area." AND location_ID = ".$location;
       $result = $db->query($query);
       if($result->num_rows > 1){
           $employees = array();
           while($row = $result->fetch_assoc()){
               array_push($employees, $row);
           }
           return $employees;
       }
       if($result->num_rows == 1){
           return $result->fetch_assoc();
       }
       return false;
   }
