https可以彻底解决劫持的问题。但是一般虚拟主机都不支持 https,难道http只能任流氓们恶意劫持么?
既然只有第一次访问时才会出现抽奖链接,通过JS在浏览器中检测,如果发现 被植入的 代码,则自动刷新网页,就可以解决被劫持的问题了。
现在要做的就是得到 被植入的代码。找了一圈,没有找到检查的工具。网站传输到客户的浏览器,需要三个步骤:【1】服务器 -> 【2】运行商 -> 【3】客户浏览器。
劫持出现在第【2】步,因为离开了服务器,已经不受控制了。但是第【3】部的浏览器可以通过JS来控制。通过 Ajax 上传 客户最终获取到的代码,就可以对进行分析了。
运行效果如下:
<?php //根据访问域名,创建不同的目录 $log_path = $_SERVER['SERVER_NAME']; if( !is_dir($log_path) ){ mkdir($log_path); } //根据访客IP,分别记录 $log_path .= '/' . $_SERVER['REMOTE_ADDR']; if( !is_dir($log_path) ){ mkdir($log_path); } //按天分组 $log_path .= '/' . date('Y-m-d', time()); if( !is_dir($log_path) ){ mkdir($log_path); } //根据时间生成文件名 $log_file = $log_path . '/' . date('His', time()) . '_' . rand() . '.html'; //保存日志 $html = ''; $html .= 'URL:/' . post('url') . '<hr>'; $html .= 'HEAD:<br><textarea cols="200" rows="40">' . post('head') . '</textarea><hr>'; $html .= 'BODY:<br><textarea cols="200" rows="40">' . post('body') . '</textarea>'; file_put_contents($log_file, $html); die('{"help":"http://www.miaoqiyuan.cn/p/browser-page-tracert/","log_file":"' . $log_file . '"}'); //调用的函数 function post($input){ $post_str = isset($_POST[$input]) ? $_POST[$input] : ''; $post_str = str_replace('\\', '', $post_str); $post_str = iconv_substr($post_str, 0, 50000); //防止恶意上传假日志 return $post_str; } ?>
调用很简单,比如将 上边的php代码保存到了 /log/page_tracert.php
,然后在整站页面中都加入 以下的代码,就可以获取到 所有的访问记录了。根据访问记录,得到 被植入的代码后,就可以进行检测脚本的开发了。
$(function(){ $.post('/log/page_tracert.php',{ url : location.href, head : $('head').html(), body : $('body').html(), },function(){}); });
注意:得到数据后,一定要尽快删除 测试代码。因为他会产生大量的日志,产生虚拟主机双倍的流量消耗
上面是我整理给大家的,希望今后会对大家有帮助。

JavaScript's application in the real world includes front-end and back-end development. 1) Display front-end applications by building a TODO list application, involving DOM operations and event processing. 2) Build RESTfulAPI through Node.js and Express to demonstrate back-end applications.

The main uses of JavaScript in web development include client interaction, form verification and asynchronous communication. 1) Dynamic content update and user interaction through DOM operations; 2) Client verification is carried out before the user submits data to improve the user experience; 3) Refreshless communication with the server is achieved through AJAX technology.

Understanding how JavaScript engine works internally is important to developers because it helps write more efficient code and understand performance bottlenecks and optimization strategies. 1) The engine's workflow includes three stages: parsing, compiling and execution; 2) During the execution process, the engine will perform dynamic optimization, such as inline cache and hidden classes; 3) Best practices include avoiding global variables, optimizing loops, using const and lets, and avoiding excessive use of closures.

Python is more suitable for beginners, with a smooth learning curve and concise syntax; JavaScript is suitable for front-end development, with a steep learning curve and flexible syntax. 1. Python syntax is intuitive and suitable for data science and back-end development. 2. JavaScript is flexible and widely used in front-end and server-side programming.

Python and JavaScript have their own advantages and disadvantages in terms of community, libraries and resources. 1) The Python community is friendly and suitable for beginners, but the front-end development resources are not as rich as JavaScript. 2) Python is powerful in data science and machine learning libraries, while JavaScript is better in front-end development libraries and frameworks. 3) Both have rich learning resources, but Python is suitable for starting with official documents, while JavaScript is better with MDNWebDocs. The choice should be based on project needs and personal interests.

The shift from C/C to JavaScript requires adapting to dynamic typing, garbage collection and asynchronous programming. 1) C/C is a statically typed language that requires manual memory management, while JavaScript is dynamically typed and garbage collection is automatically processed. 2) C/C needs to be compiled into machine code, while JavaScript is an interpreted language. 3) JavaScript introduces concepts such as closures, prototype chains and Promise, which enhances flexibility and asynchronous programming capabilities.

Different JavaScript engines have different effects when parsing and executing JavaScript code, because the implementation principles and optimization strategies of each engine differ. 1. Lexical analysis: convert source code into lexical unit. 2. Grammar analysis: Generate an abstract syntax tree. 3. Optimization and compilation: Generate machine code through the JIT compiler. 4. Execute: Run the machine code. V8 engine optimizes through instant compilation and hidden class, SpiderMonkey uses a type inference system, resulting in different performance performance on the same code.

JavaScript's applications in the real world include server-side programming, mobile application development and Internet of Things control: 1. Server-side programming is realized through Node.js, suitable for high concurrent request processing. 2. Mobile application development is carried out through ReactNative and supports cross-platform deployment. 3. Used for IoT device control through Johnny-Five library, suitable for hardware interaction.

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),
