关于POST方式传递数据的问题
最近在研究怎么用POST方式传递数据
我想得到的效果是,打开网页a,向一个网页b传递一个字符串
然后在网页b上显示这个字符串。
在网上找到一份代码,是这样的
网页a的代码:
$uri = "http://localhost/handle.php";
// 参数数组
$data = array (
'name' => 'tanteng'
// 'password' => 'password'
);
$ch = curl_init ();
// print_r($ch);
curl_setopt ( $ch, CURLOPT_URL, $uri );
curl_setopt ( $ch, CURLOPT_POST, 1 );
curl_setopt ( $ch, CURLOPT_HEADER, 0 );
curl_setopt ( $ch, CURLOPT_RETURNTRANSFER, 1 );
curl_setopt ( $ch, CURLOPT_POSTFIELDS, $data );
$return = curl_exec ( $ch );
curl_close ( $ch );
print_r($return);
?>
网页b的代码
echo 'this is the posted data';
if(isset($_POST['name'])){
if(!empty($_POST['name'])){
echo '您好,',$_POST['name'].'!';
}
}
?>
在我电脑上实验的结果是打开网页b只显示 this is the posted data
而网页a上显示 您好,tanteng!
有谁能给我解释下为什么吗?如果我想让这句话在网页b上显示该怎么做?
------解决思路----------------------
可以用數據庫或文件保存。
a.php
<br /><?php<br />$uri = "http://localhost/handle.php";<br />// 参数数组<br />$data = array (<br /> 'name' => 'tanteng' <br />// 'password' => 'password'<br />);<br /> <br />$ch = curl_init ();<br />// print_r($ch);<br />curl_setopt ( $ch, CURLOPT_URL, $uri );<br />curl_setopt ( $ch, CURLOPT_POST, 1 );<br />curl_setopt ( $ch, CURLOPT_HEADER, 0 );<br />curl_setopt ( $ch, CURLOPT_RETURNTRANSFER, 1 );<br />curl_setopt ( $ch, CURLOPT_POSTFIELDS, $data );<br />$return = curl_exec ( $ch );<br />curl_close ( $ch );<br /> <br />print_r($return);<br />?><br />
handle.php
<br /><?php<br />$name = isset($_POST['name'])? $_POST['name'] : '';<br />file_put_contents('tt.txt', $name, true);<br />echo 'success';<br />?><br />
b.php
<br /><?php<br />echo 'this is the posted data';<br />if(file_exists('tt.txt')){<br /> $name = file_get_contents('tt.txt');<br /> if(!empty($name)){<br /> echo '您好,',$name.'!';<br /> }<br />}<br />?><br />

What’s still popular is the ease of use, flexibility and a strong ecosystem. 1) Ease of use and simple syntax make it the first choice for beginners. 2) Closely integrated with web development, excellent interaction with HTTP requests and database. 3) The huge ecosystem provides a wealth of tools and libraries. 4) Active community and open source nature adapts them to new needs and technology trends.

PHP and Python are both high-level programming languages that are widely used in web development, data processing and automation tasks. 1.PHP is often used to build dynamic websites and content management systems, while Python is often used to build web frameworks and data science. 2.PHP uses echo to output content, Python uses print. 3. Both support object-oriented programming, but the syntax and keywords are different. 4. PHP supports weak type conversion, while Python is more stringent. 5. PHP performance optimization includes using OPcache and asynchronous programming, while Python uses cProfile and asynchronous programming.

PHP is mainly procedural programming, but also supports object-oriented programming (OOP); Python supports a variety of paradigms, including OOP, functional and procedural programming. PHP is suitable for web development, and Python is suitable for a variety of applications such as data analysis and machine learning.

PHP originated in 1994 and was developed by RasmusLerdorf. It was originally used to track website visitors and gradually evolved into a server-side scripting language and was widely used in web development. Python was developed by Guidovan Rossum in the late 1980s and was first released in 1991. It emphasizes code readability and simplicity, and is suitable for scientific computing, data analysis and other fields.

PHP is suitable for web development and rapid prototyping, and Python is suitable for data science and machine learning. 1.PHP is used for dynamic web development, with simple syntax and suitable for rapid development. 2. Python has concise syntax, is suitable for multiple fields, and has a strong library ecosystem.

PHP remains important in the modernization process because it supports a large number of websites and applications and adapts to development needs through frameworks. 1.PHP7 improves performance and introduces new features. 2. Modern frameworks such as Laravel, Symfony and CodeIgniter simplify development and improve code quality. 3. Performance optimization and best practices further improve application efficiency.

PHP type prompts to improve code quality and readability. 1) Scalar type tips: Since PHP7.0, basic data types are allowed to be specified in function parameters, such as int, float, etc. 2) Return type prompt: Ensure the consistency of the function return value type. 3) Union type prompt: Since PHP8.0, multiple types are allowed to be specified in function parameters or return values. 4) Nullable type prompt: Allows to include null values and handle functions that may return null values.

SecLists
SecLists is the ultimate security tester's companion. It is a collection of various types of lists that are frequently used during security assessments, all in one place. SecLists helps make security testing more efficient and productive by conveniently providing all the lists a security tester might need. List types include usernames, passwords, URLs, fuzzing payloads, sensitive data patterns, web shells, and more. The tester can simply pull this repository onto a new test machine and he will have access to every type of list he needs.
