phppost500_用PHP做登陆注册页面

❶ 用vue访问接口能正常返回数据，但是报500错误，用postman提交一样的参数请求也正常，这是为什么呢

我的也是用POSTman可以获取数据,我这边用axios去获取,加了application/x-www-form-urlencoded也是传不过来数据,一直报500,说是XMLhttp请求不对,困扰了好几天了,一直在想有没有人专写一个接口组件,可以接受各种类型的接口,每次还要去针对的写,太麻烦.什么form-data,x-www-form-urlencoded

❷ 用php做登陆注册页面

登录页：login.php

//print_r($sql);
$ar=mysql_query($sql);
if($ar)
{
if($row=mysql_fetch_array($ar))
{
session_start();
if($_POST["yanzheng"])
{
if($yanzheng!=$_session[pic]||$yanzheng=="")
{
echo "验证码输入有误";
exit;
}
if($yanzheng==$_session[pic])
{
header("location:index.php");
}
}
}
else
{
echo "用户名或密码错误";
}
}
}

?>

❸ php 多图片上传$_FILES[]为空值，而且报post 500的错误

报500错误，说明你代码程序有问题。。。你最好发代码看看。
