我检查了许多示例代码,但仍在努力使我的工作正常。我正在尝试从我的 PHP 脚本生成 XML 输出。
登录.php
<?php
mysql_connect("localhost", "root", "") or die("cannot connect");
mysql_select_db("ConquestOfLancaster") or die("cannot select DB");
$username = $_REQUEST['username'];
$password = sha1($_REQUEST['password']);
$username = mysql_real_escape_string($username);
$domDoc = new DOMDocument;
$rootElt = $domDoc->createElement('root');
$rootNode = $domDoc->appendChild($rootElt);
$sql = "SELECT user_id, user_name FROM tbl_user WHERE user_name='$username' and user_pass='$password'";
$result = mysql_query($sql);
$count=mysql_num_rows($result);
if($count > 0){
//echo("welcome");
$rootAtr = $domDoc->createAttribute('success');
$rootAtrVal = $domDoc->createTextNode('TRUE');
$rootAtr->AppendChild($rootAtrVal);
$rootElt->AppendChild($rootAtr);
$subElt = $domDoc->createElement('username');
$subNode = $rootNode->appendChild($subElt);
$textNode = $domDoc->createTextNode($username);
$subNode->appendChild($textNode);
echo htmlentities($domDoc->saveXML());
} else{
//echo("not exist");
$rootAtr = $domDoc->createAttribute('success');
$rootAtrVal = $domDoc->createTextNode('FALSE');
$rootAtr->AppendChild($rootAtrVal);
$rootElt->AppendChild($rootAtr);
echo htmlentities($domDoc->saveXML());
}
?>
浏览器上的输出是
<?xml version="1.0"?> <root success="TRUE"><username>user1</username></root>
我的主要问题是与此 PHP 交互的 iOS 应用程序无法解析此结果。我做错了什么?
