这个页面执行一次以后,再次执行,修改?user=后面的参数,执行结果没有任何变化。
回复讨论(解决方案)
$user=$_POST["user"];
改为
$user=$_GET["user"];
你不是用POST接收的吗?改?user=后面参数,对POST没有影响啊
谢谢楼上的。代码修正为:
<?phprequire 'Inc/function.php';header("Expires:-1");header("Cache-Control:no-cache");header("Pragma:no-cache");$user=$_GET["user"];if (!isset($user)){ echo("0||"); }else{ $con = mysql_connect(DBHOST,DBUSER,DBPW); if (!$con) { die("0||"); //die('数据库连接出错: ' . mysql_error()); } mysql_select_db(DBNAME, $con); $result = mysql_query("SELECT uid,password,salt FROM `pre_ucenter_members` where username='".checkstr($user)."'"); mysql_close($con); $row=mysql_fetch_row($result); echo("$row[0]|$row[1]|$row[2]");}?>
我犯了两个低级错误。除了post改get以外,
checkstr(user)改为checkstr($user)
执行正常了

You should care about DependencyInjection(DI) because it makes your code clearer and easier to maintain. 1) DI makes it more modular by decoupling classes, 2) improves the convenience of testing and code flexibility, 3) Use DI containers to manage complex dependencies, but pay attention to performance impact and circular dependencies, 4) The best practice is to rely on abstract interfaces to achieve loose coupling.

Select DependencyInjection (DI) for large applications, ServiceLocator is suitable for small projects or prototypes. 1) DI improves the testability and modularity of the code through constructor injection. 2) ServiceLocator obtains services through center registration, which is convenient but may lead to an increase in code coupling.
