PHP文件未接收到$_POST

Question

我的C#代码有一个问题，它从登录表单中发布数据，以便在PHP页面上进行验证。

在我的开发页面上，它工作得很好，但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");
}

它非常类似，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(这两个页面)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));
        }
    }

有什么想法吗？

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($_POST“用户名”，$_POST“密码”)的结果为NULL和NULL。

更新2：

$print_r($_SERVER)的结果：

Answer 1

UploadStringAsync

函数将字符串作为原始数据发送，它不能在$_POST数组中看到，php代码使用

file_get_contents('php://input')

来接收它，或者在C#中使用

NameValueCollection reqparm = new NameValueCollection();
reqparm.Add("username", "asd");
reqparm.Add("pass", "smthg");
...
wc.UploadValues(this.url, "POST", this.reqparm);

Answer 2

嗯，我认为你应该在头文件中获取POST方法，而不是get方法。

Answer 3

试着去找

method="post"

在你的<form>标签里，或者其他什么地方。如果你看到这样的东西..。

method="get"

..。那是你的问题。将方法更改为post。
