錯誤：「您的請求超時，請重試請求。」與Android和PHP程序

我有一個Android應用程序與託管服務提供商上的服務器通信。此應用程序發送一個http請求php腳本檢索請求並在數據庫中執行操作。我改變了數據庫，我修改了程序，現在我在服務器上發現錯誤：「您的請求超時，請重試請求。」錯誤：「您的請求超時，請重試請求。」與Android和PHP程序

當我在firefox或chrome等瀏覽器中執行命令http時，命令執行正確，通過防止執行代碼時發生錯誤。

這不是腳本或http請求，因此我根本沒有看到可能發生的情況。你可以幫我嗎？非常感謝你。

有Android的代碼：

有PHP腳本代碼：

$base = mysql_connect ('sql31.free-h.org:3306', '*****', '******'); 
mysql_select_db ('routeslibre', $base) ; 
$variable = $_GET['variable']; 
$first_token = strtok($variable, ";;;"); 
$second_token = strtok(";;;"); 
$req =mysql_query("SELECT message, date from routeslibre.routeslibre where departement='$first_token' AND  voie='$second_token' ORDER BY date"); 
$output=array(); 
while ($row=mysql_fetch_array($req)) {  
$output[]=$row;  
} 
//on encode en JSON 
print(json_encode($output)); 
mysql_free_result ($req);

當我停止就行調試器「is.close（）;」值「db」等於「<html> Your request timed out. Please retry the request」

如果你不介意，你可以給我一個技巧，找到錯誤的方法嗎？

我，就把這行代碼： int test = response.getStatusLine().getStatusCode(); 和測試值是408左右（如在網站所描述）的平均值我在託管服務提供商有一個錯誤。但是爲什麼當我把http請求，從代碼retreived：值http://routeslibre.fr/"+ myFichierPHPbase + "?variable=" + mydataFromHMI，當我把它放在一個Web客戶端作爲鉻或Firefox，我的PHP腳本工作非常發現......我不明白....？？

有了這段代碼，那並不完美：有時候它的工作有時候不行。當調試器在執行操作中設置時，將出現異常，其值僅爲「null」。你可以幫幫我嗎？

這裏是一個不工作找到代碼：

HttpGet httpGet = new HttpGet(url); 
HttpParams httpParameters = new BasicHttpParams(); 
// Set the timeout in milliseconds until a connection is established. 
// The default value is zero, that means the timeout is not used. 
int timeoutConnection = 3000; 
HttpConnectionParams.setConnectionTimeout(httpParameters, timeoutConnection); 
// Set the default socket timeout (SO_TIMEOUT) 
// in milliseconds which is the timeout for waiting for data. 
int timeoutSocket = 5000; 
HttpConnectionParams.setSoTimeout(httpParameters, timeoutSocket); 

DefaultHttpClient httpClient = new DefaultHttpClient(httpParameters); 
HttpResponse response = httpClient.execute(httpGet);

我找到了一個解決方案，我遍歷，直到我有一個請求（狀態從服務器retreived等於200）或執行代碼，如果請求沒有提供任何結果，則會啓動錯誤。這裏有我的解決方案：

 String httpRequest = new String("http://routeslibre.fr/"+ myFichierPHPbase + "?variable=" + mydataFromHMI); 
     HttpPost request = new HttpPost(httpRequest); 
     HttpParams httpParameters = new BasicHttpParams(); 
     HttpProtocolParams.setVersion(httpParameters, HttpVersion.HTTP_1_1); 
     HttpProtocolParams.setContentCharset(httpParameters, HTTP.UTF_8); 

     DefaultHttpClient httpclient = new DefaultHttpClient(httpParameters); 

     HttpResponse response = null; 
     for(int i= 0; i < 30; i++){ 
      response = httpclient.execute(request); 
      if (response.getStatusLine().getStatusCode() == 200){ 
       break; 
      }else if (i == 29){ 

       //ERROR CODE 
      } 
     }
