如何从PHP中获取Android的值

Question

我想为android实现服务器端。 Forthis android系统中我使用此代码：在服务器端

List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>(1); 
     // Get the deviceID 
     nameValuePairs.add(new BasicNameValuePair("reg_id", val[1])); 
     nameValuePairs.add(new BasicNameValuePair("App_Name",val[2])); 
     nameValuePairs.add(new BasicNameValuePair("App_Version", val[3])); 

现在我想访问这些值并将其存储在数据库中。我的PHP代码：

include('connectdb.php'); 

$Reg_ID=$_REQUEST['reg_id']; 
$App_Name=$_REQUEST['App_Name']; 
$App_Version=$_REQUEST['App_Version']; 

if($_REQUEST['reg_id']!='NULL' && $_REQUEST['App_Name']!='NULL' && $_REQUEST['App_Version']!='NULL') 
{ 
    mysqli_query($con,"INSERT INTO registration (Reg_ID, APP_Name,App_Version) 
    VALUES ('".$_REQUEST['reg_id']."', '".$_REQUEST['App_Name']."','".$_REQUEST['App_Version']."')"); 

} 
else 
{ 
} 

mysqli_close($con); 

但是在PHP我得到这些错误：

注意：未定义指数：REG_ID在C：\ XAMPP \ htdocs中\ GCM \ addReg.php上 线5

说明：未定义指数：APP_NAME在C：\ XAMPP \ htdocs中\ GCM \ addReg.php上 线6

说明：未定义指数：APP_VERSION在C：\ XAMPP \ htdocs中\ GCM \ addReg.php 第7行

警告：mysqli_close（）预计参数1是mysqli的，在C给定的资源 ：\ XAMPP \ htdocs中\ GCM \ addReg.php上线24

任何帮助

include('connectdb.php'); 

//First, check whether the values exist and only then use them. 
if(isset($_REQUEST['reg_id'], $_REQUEST['App_Name'], $_REQUEST['App_Version'])) 
{ 
    $id = mysqli_real_escape_string($con, $_REQUEST['req_id']) ; 
    $name = mysqli_real_escape_string($con, $_REQUEST['App_Name']) ; 
    $version = mysqli_real_escape_string($con, $_REQUEST['App_Version']) ; 

    $query = "INSERT INTO registration (Reg_ID, APP_Name, App_Version) 
    VALUES ('{$id}', '{$name}','{$version}') ;" ; 

    $result = mysqli_query($con, $query) ; 
    if ($result){ 
    echo "Success" ; 
    } else { 
    echo "Failure" ; 
    } 
} else { 
    echo "Not sufficient data for request" ; 
} 

我刚刚纠正了条件的基本流程并转义了特殊字符来保护您的数据库。它应该工作。

尝试使用$ _POST而不是$ _REQUEST，如果你要发送的数据。为了清楚起见 - 在第7行和下面重新使用分配的变量（$ Reg_ID，$ App_Name，$ App_Version）而不是$ _REQUEST [...]。
