POST調用不會將REST API的結果返回到iPhone應用程序

我無法讓iPhone應用程序正確地使用我的API發送POST。撥打電話時，根本沒有結果返回。POST調用不會將REST API的結果返回到iPhone應用程序

的POST調用旨在發送消息（存儲的信息，覈對一些參數，並啓動「推」通知）
的電話後從形式適用於以.php文件，但不通過應用程序時使用。返回結果：{「message」：{「message」：{「saved」：1}}，「pressed」：1，「error」：[]}推測期間的錯誤是預期的，因爲test2.php不是發送消息到移動設備，只是數據庫。

下面是應用

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];

什麼可能會造成應用程序加載的index.php沒有結果偵錯碼？ post變量設置正確，即使'push'失敗，仍然應該將消息輸入數據庫（因爲test2.php成功）。

非常感謝您的任何見解。

下面是從我的應用程序開發者的迴應：

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.

該請求具有以下要求：

位置（號碼）
點（數字）
號（數字）
消息（字符串）
發送（日期時間：YYYY-MM-DD HH：MM：SS）

這裏的一個PHP代碼SAN的安全部分，以減少長度。

，處理一切開始的情況下=後的呼叫（將得到的是檢索消息）

$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; 
}

而這裏的配套功能：

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; 
}

是有可能記錄應該由PHP處理的請求嗎？這裏信息太少，無法給出有意義的答案。

感謝您的答覆POST方法，我在編輯中添加日誌從我的開發人員儘管它不包含非常多的信息。如果有幫助，我還添加了處理POST調用的PHP文件的很大一部分。讓我知道我是否可以提供任何可能有用的信息。 – user1324246 2012-04-10 16:52:49

我想你得到的是一堆php代碼，因爲無論你發送的數據是不是插入到數據庫中。我認爲可能有兩個原因。

問題發送數據或有問題的接收數據

使用如下代碼

NSString *[email protected]"Your url"; 

NSURL *url = [NSURL URLWithString:string]; 

NSMutableURLRequest *request = [[NSMutableURLRequest alloc]initWithURL:url]; 
[request setHTTPMethod:@"POST"]; 

NSString *mpfBoundry = [NSString stringWithString:@"---------------------------"]; 
NSString *contentType = [NSString stringWithFormat:@"application/x-www-form-urlencoded; boundary=%@", mpfBoundry]; 
[request addValue:contentType forHTTPHeaderField: @"Content-Type"]; 

    NSString* body =[NSString stringWithFormat:@"column1=%@&column2=%@&column3=%@", data1,data2,data3]; 

[request setHTTPBody:[body dataUsingEncoding:NSUTF8StringEncoding]]; 

NSURLConnection *connection= [[NSURLConnection alloc]initWithRequest:request delegate:self]; 

[connection start];
