php代码 ：

include 'connection.php';
if($_SERVER['REQUEST_METHOD']=='POST'){
    $name=$_POST['name'];
    $password=$_POST['password'];
    
    $query = mysqli_query($con,"SELECT * FROM `user` WHERE `name`='$name' && `password`='$password'");
    $rows = mysqli_num_rows($query);
    if($rows==0){
        echo "failure";
    }else{
        echo "succeed";
    }

}

mysqli_close($con);

问题是当我运行此代码时，sqlmap -u "http://192.168.0.106/get_method/get_data_login/" --data="name=name&password=pass" -D get_method -T user --dump它正在发送，data="name=name&password=pass"而数据库中没有数据在此输入图像描述

而且，当我运行该代码时，我只获得数据。

+-------+--------+----------+---------------------+
| name  | serial | password | timestamp           |
+-------+--------+----------+---------------------+
| hello | 222    | hey      | 2021-03-26 11:21:25 |
+-------+--------+----------+---------------------+

为什么我无法获取所有数据？我也尝试过这个，sqlmap -u "http://192.168.0.106/get_method/get_data_login/" --data="name=hello&password=hey" -D get_method -T user --dump虽然我得到了相同的输出..

php首先看看你的代码

include 'connection.php';
if($_SERVER['REQUEST_METHOD']=='POST'){
    $name=$_POST['name'];
    $password=$_POST['password'];
    
    $query = mysqli_query($con,"SELECT * FROM `user` WHERE `name`='$name' && `password`='$password'");
    $rows = mysqli_num_rows($query);
    if($rows==0){
        echo "failure";
    }else{
        echo "succeed";
    }

}

mysqli_close($con);

sql无论我将发送到此文件，它现在只会检查代码。SELECT * FROM `user` WHERE `name`='$name' && `password`='$password'从用户表中选择名称=“无论用户发送的内容”和密码=“无论用户发送的内容”的所有内容。这就是为什么我没有列出所有清单的原因。
