我的 C# 代码有问题,该代码从登录表单发布数据以在 PHP 页面上进行验证。
在我的开发页面上,它工作正常,但是当我切换到生产页面时,它停止工作。(两个网页位于同一台服务器上)。
我的登录页面(开发)如下所示:
$user = DB_Login($_POST["username"], $_POST["password"]);
if (!is_null($user))
{
SetLoginCookies($user["userID"], $user["sessionID"]);
echo "valid";
}
else
echo "invalid";
我的生产页面如下所示:
$responseArray = DB_Login($_POST["username"], $_POST["password"]);
if (is_null($responseArray))
{
die("invalid");
}
它非常相似,但我不明白为什么我的生产页面从不接收 POST 变量,它总是死掉。
我的 C# 代码(其中任一页面)如下所示:
private void Login_Click(object sender, RoutedEventArgs e)
{
string sendData = "";
Uri site = new Uri("site");
WebClient wc = new WebClient();
wc.Headers[HttpRequestHeader.ContentType] = "application/x-www-form-urlencoded";
sendData += "username=" + usrname.Text;
sendData += "&password=" + pword.Password;
wc.Headers[HttpRequestHeader.ContentLength] = sendData.Length.ToString();
wc.UploadStringCompleted += new UploadStringCompletedEventHandler(wc_UploadStringCompleted);
wc.UploadStringAsync(site, "POST", sendData);
}
private void wc_UploadStringCompleted(object sender, UploadStringCompletedEventArgs e)
{
if (e.Result.Equals("invalid"))
{
return;
}
else
{
MessageBox.Show(e.Result.ToString());
//Navigate to next page
NavigationService.Navigate(new Uri("/ControlPanel.xaml", UriKind.Relative));
}
}
有任何想法吗?
更新:
DB_Login 函数如下所示:
function DB_Login($username, $password)
{
$password = md5($password);
$username = mysql_escape_string($username);
$request = DB_ExecuteQuery("SELECT userID, isAdmin
FROM accounts
WHERE username = '$username' AND password = '$password'");
if ($request->num_rows == 0)
return NULL;
$requestArray = $request->fetch_array();
$response = array("userID" => $requestArray["userID"]);
$response["sessionID"] = mysql_escape_string(generateGuid());
$response["isAdmin"] = $requestArray["isAdmin"];
DB_ExecuteQuery("UPDATE accounts
SET sessionID = '". $response['sessionID'] ."'
WHERE userID = ". $response['userID']);
DB_SetLastLogin($requestArray['userID']);
return $response;
}
var_dump($_POST["username"], $_POST["password"]) 的结果是 NULL 和 NULL。
更新2:
$print_r($_SERVER) 的结果:
