Question

我正在创建一个需要用户登录的应用。当我单击登录按钮时，我只得到else语句。我检查了我的控制台日志，但没有显示，没有错误。我尝试了很多次，我在Corona SDK论坛上问过，但没有任何帮助。这是我的代码。

login.lua：

local composer = require( "composer" )
local scene = composer.newScene()

local widget = require("widget")
-- forward declare the text fields
local json = require("json")

local username
local pw

local function emptyFields( event )
if ( username.text == "" or pw.text == "" ) then

      local alert = native.showAlert( "Empty fields", "Fill in all fields .", { "Try again" }  )

    return true 

    else
    return false

end
end

local function networkListener( event )

if ( event.isError ) then
    print( "Network error.")
else
    if event.response == "success" then
        -- put the code here to go to where the user needs to be
        -- after a successful registration
        composer.gotoScene("userarea")

    else
        -- put code here to notify the user of the problem, perhaps
        -- a native.alert() dialog that shows them the value of event.response
        -- and take them back to the registration screen to let them try again

      local alert = native.showAlert( "Error Logging In", "There was an error logging in.", { "Try again" }  )

end
end
end

local function userLogin( event )
if ( "ended" == event.phase ) then
 if emptyFields() == true then  

    else

    local parameters = {}
    parameters.body = "Login=1&username=" .. username.text .. "&pw=" .. pw.text

    local URL = "http://hash.comxa.com/login.php"
    network.request(URL, "POST", networkListener, parameters)

    local headers = {} 

    headers["Content-Type"] = "application/x-www-form-urlencoded" 
    headers["Accept-Language"] = "en-US"

    parameters.headers = headers

end
end
end

local function registerLink( event )
if ( "ended" == event.phase ) then
     composer.gotoScene("register")

end
end

Login.PHP：

session_start();

             // Check connection
             if ($con->connect_error) {
             die("Check connection.");
                }

                 $username = ($_POST["username"]);
                 $pw = ($_POST["pw"]);

                 if(isset($_POST['Login'])) {

                         $username = mysqli_real_escape_string($con, $_POST["username"]);
                         $pw = mysqli_real_escape_string($con, $_POST["pw"]);

                $sql = "SELECT * FROM users where username = '" . $username . "' and pw = '" . $pw . "'";
                    $result = mysqli_query($con, $sql);
                    $count = mysqli_num_rows($result);

                if($count == 1){

                $_SESSION['logged in'] = true;

                }
                else
                {
                echo"username or password is incorrect.";
                }
}

在建立连接之前，您需要设置标头。尝试

local function userLogin( event )
if ( "ended" == event.phase ) then
 if emptyFields() == true then  

    else

    local parameters = {}
    parameters.body = "Login=1&username=" .. username.text .. "&pw=" .. pw.text

    local headers = {} 

    headers["Content-Type"] = "application/x-www-form-urlencoded" 
    headers["Accept-Language"] = "en-US"

    parameters.headers = headers

    local URL = "http://hash.comxa.com/login.php"
    network.request(URL, "POST", networkListener, parameters)

end
end
end
