我有一个在线的 mySQL 数据库。我可以更新分数,而且效果很好。现在我想向 Android 返回一个行号,但我做不到。我的 php 文件:
<?php
$name = $_REQUEST['jugador'];
$score = $_REQUEST['score'];
$moles = $_REQUEST['topos'];
$con = mysql_connect("hots","db","pass");
if (!$con)
{
die('Could not connect: ' . mysql_error());
}
mysql_select_db("a5385197_scores", $con);
mysql_query("INSERT INTO scores VALUES (null, '$name', $score, $moles)");
$result = mysql_query("SELECT COUNT(1) FROM scores WHERE score >= $score");
echo json_encode($result);
mysql_close($con);
?>
插入工作正常,Select 语句返回正确值,但我无法发送到 Android。我要响应的 Android 代码:
try {
BufferedReader reader = new BufferedReader(new InputStreamReader(is,"iso-8859-1"),8);
StringBuilder sb = new StringBuilder();
String line = null;
while ((line = reader.readLine()) != null) {
sb.append(line + "\n");
}
is.close();
result = sb.toString();
Log.i("miTraza","Recive: "+result);
}catch(Exception e){
Log.e("miError", "Error converting result "+e.toString());
}
结果我得到一个错误:

我从 PHP 开始,所以很容易出错。
谢谢你的帮助。
