Question

我正在尝试在JS文件和PHP文件之间传递数据，但PHP中的变量$_POST不起作用，因此我无法在应用程序中进化！

JS代码：

var params = String(input.value);
    var xhr = Titanium.Network.createHTTPClient();
    xhr.open('GET','http://10.0.2.2/jobfinder/teste_demo_grafica/Resources/teste.php');
    xhr.send(params);
    xhr.onload = function(){

    var response = this.responseText;
    alert(response);
    if (response != null)
    {
        alert("voltou ao js e funca");
    }
    else
    {
        alert("-.-");
    }
    };

    xhr.setRequestHeader("Content-Type","application/x-www-form-urlencoded");

    xhr.onerror = function(e){alert('Transmission error: ' + e.error);};

});

现在是php代码：

<?php

// Connect to the database(host, username, password)
$con = mysql_connect('localhost','root','');

if (!$con)
{
    return ("Failed to make connection.");
    exit;
}

// Select the database. Enter the name of your database (not the same as the table name)
$db = mysql_select_db('jobfinder');
if (!$db)
{
    echo "Failed to select db.";
    exit;
}
$pesquisa= $_POST[params];
echo "pesquisa";
$sql = "SELECT * FROM oferta WHERE titulo like '%$pesquisa%'";  
$query = mysql_query($sql); 

if (mysql_num_rows($query) > 0)
{

    $row = mysql_fetch_array($query);
    $response = array(
        'titulo' => $row['titulo'],
        'oferta' => $row['descricao_oferta']
    );
    json_encode($response);
    echo $response['titulo'];

}
else
{

    // Else the username and/or password was invalid! Create an array, json_encode it and echo it out
    $response =  array(
        'message' => 'Não existem ofertas para esta pesquisa'
    );
    json_encode($response);


}
echo "php mode off";
?>

猜测，您的JavaScript是通过GET发送数据：

xhr.open('GET','http://10.0.2.2/jobfinder/teste_demo_grafica/Resources/teste.php');

但你的PHP正在寻找POST。将POST更改为GET，它可能会起作用。反之亦然

我现在有解决方案！如果我们看到这部分代码：

var params = String(input.value);
 ** var xhr = Titanium.Network.createHTTPClient();
    xhr.open('GET','http://10.0.2.2/jobfinder/teste_demo_grafica/Resources/teste.php');
    xhr.send(params);
    xhr.onload = function(){**

    var response = this.responseText;
    alert(response);
    if (response != null)
    {
        alert("voltou ao js e funca");
    }
    else
    {
        alert("-.-");
    }
    };

    xhr.setRequestHeader("Content-Type","application/x-www-form-urlencoded");

    xhr.onerror = function(e){alert('Transmission error: ' + e.error);};

});

**之间的瑕疵是问题...... 所以我喜欢这个：

var url = "http://10.0.2.2/jobfinder/tessssssste/Resources/teste.php";//bug do titanium resolvido 
    var params = "?params=" + input.value;
    var encodedURI = encodeURI(url + params);

    var xhr = Titanium.Network.createHTTPClient();
    xhr.open("GET", encodedURI);
    xhr.send();

    xhr.onload = function(){

现在它有效 TY EVERYBODY !!!!

$ _POST变量在php Titanium中不起作用
