url html
先举个例子 http://wenku.baidu.com/view/a4cee123de80d4d8d15a4fba.html1.这是百度文库中的一个地址,我想知道a4cee123de80d4d8d15a4fba是得怎么出来的。
2.审查元素-下载按钮,
<a class="ic reader-download" href="###" data-toolsbar-log="download" alog-action="htmltoolbar.download"></a></div>这段代码将下载链接隐藏了,是怎么做到的?
3.查看网页源代码,发现2中的那段代码也被隐藏了,怎么回事?
请大家给解释一下,谢谢!

1.或许人家就是存了一个这样的文件名的文件.或许服务器看到a4cee123de80d4d8d15a4fba后进行逆运算得出真实文件名,可能性很多
2.下载链接不一定要指向下载的文件的地址,因为可以把它当做一个按钮,点击时触发js来进行下载操作.
3.如果网页上对应位置是个空元素,页面载入时用js动态的添加内容 查看源代码就会发现是空的
上边说的很可能不准确,因为百度具体用了什么样的技术我并不能保证,我只能说,我说的那些可以实现类似的效果.并且推测是用js实现的
研究百度的做法不如研究下要实现什么样的效果需要怎么做来得快

我都研究了一下午了,就是不知道怎么隐藏地址啊。我就是想让别人怎么样都找不到我文件的文件名和地址。
最简单的方法:php生成下载链接的时候用base64encode一个filepath+time,下载链接类似与download.php?hash=xxxxxxxxxxxxxx,用户点击,你拿到hash之后ecode,如果time没有过期,header里给人家文件
$file = "/tmp/dummy.tar.gz"; header("Content-type: application/octet-stream"); header('Content-Disposition: attachment; filename="' . basename($file) . '"'); header("Content-Length: ". filesize($file)); readfile($file);

就是通过js跳转的

PHP remains a powerful and widely used tool in modern programming, especially in the field of web development. 1) PHP is easy to use and seamlessly integrated with databases, and is the first choice for many developers. 2) It supports dynamic content generation and object-oriented programming, suitable for quickly creating and maintaining websites. 3) PHP's performance can be improved by caching and optimizing database queries, and its extensive community and rich ecosystem make it still important in today's technology stack.

In PHP, weak references are implemented through the WeakReference class and will not prevent the garbage collector from reclaiming objects. Weak references are suitable for scenarios such as caching systems and event listeners. It should be noted that it cannot guarantee the survival of objects and that garbage collection may be delayed.

The \_\_invoke method allows objects to be called like functions. 1. Define the \_\_invoke method so that the object can be called. 2. When using the $obj(...) syntax, PHP will execute the \_\_invoke method. 3. Suitable for scenarios such as logging and calculator, improving code flexibility and readability.

Fibers was introduced in PHP8.1, improving concurrent processing capabilities. 1) Fibers is a lightweight concurrency model similar to coroutines. 2) They allow developers to manually control the execution flow of tasks and are suitable for handling I/O-intensive tasks. 3) Using Fibers can write more efficient and responsive code.

The PHP community provides rich resources and support to help developers grow. 1) Resources include official documentation, tutorials, blogs and open source projects such as Laravel and Symfony. 2) Support can be obtained through StackOverflow, Reddit and Slack channels. 3) Development trends can be learned by following RFC. 4) Integration into the community can be achieved through active participation, contribution to code and learning sharing.

PHP and Python each have their own advantages, and the choice should be based on project requirements. 1.PHP is suitable for web development, with simple syntax and high execution efficiency. 2. Python is suitable for data science and machine learning, with concise syntax and rich libraries.

PHP is not dying, but constantly adapting and evolving. 1) PHP has undergone multiple version iterations since 1994 to adapt to new technology trends. 2) It is currently widely used in e-commerce, content management systems and other fields. 3) PHP8 introduces JIT compiler and other functions to improve performance and modernization. 4) Use OPcache and follow PSR-12 standards to optimize performance and code quality.

The future of PHP will be achieved by adapting to new technology trends and introducing innovative features: 1) Adapting to cloud computing, containerization and microservice architectures, supporting Docker and Kubernetes; 2) introducing JIT compilers and enumeration types to improve performance and data processing efficiency; 3) Continuously optimize performance and promote best practices.

mPDF
mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
