thinkphp url中action 没有定义 也能访问到模板?
thinkphp url中action 没有定义 也能访问到模板?
最近刚刚开始接触thinkphp 的框架,但是在看公司源码的时候,发现url中的action在类中没有对应的实现方法。
thinkphp 中有空操作和空模块之说, 我本来以为是通过空操作来实现的。
最终确认的结果:根本没有经过模块,直接把action对应的模板给display了。
本人刚刚接触thinkphp 不知道为什么 求大神帮忙
------解决思路----------------------
你看下配置里面是不是开启了路由功能,路由功能可以伪造地址;不知道这个是不是你现在遇到的问题。
------解决思路----------------------

------解决思路----------------------
在进入用户自定义的action之前,会自动检测是否存在该方法
如果没有就直接读模板,连模板都没有就报一个该方法不存在之类的错误
------解决思路----------------------
这个...没仔细看过官方的,根据它的表现完全可以逆推出原理
如果你感兴趣,可以完整阅读tp的源码
------解决思路----------------------
见 ThinkPHP/Library/Think/Controller.class.php __call 方法
/**<br /> * 魔术方法 有不存在的操作的时候执行<br /> * @access public<br /> * @param string $method 方法名<br /> * @param array $args 参数<br /> * @return mixed<br /> */<br /> public function __call($method,$args) {<br /> if( 0 === strcasecmp($method,ACTION_NAME.C('ACTION_SUFFIX'))) {<br /> if(method_exists($this,'_empty')) {<br /> // 如果定义了_empty操作 则调用<br /> $this->_empty($method,$args);<br /> }elseif(file_exists_case($this->view->parseTemplate())){<br /> // 检查是否存在默认模版 如果有直接输出模版<br /> $this->display();<br /> }else{<br /> E(L('_ERROR_ACTION_').':'.ACTION_NAME);<br /> }<br /> }else{<br /> E(__CLASS__.':'.$method.L('_METHOD_NOT_EXIST_'));<br /> return;<br /> }<br /> }<br />这是一种容错技术,并不需要在使用手册中说明

PHP is a server-side scripting language used for dynamic web development and server-side applications. 1.PHP is an interpreted language that does not require compilation and is suitable for rapid development. 2. PHP code is embedded in HTML, making it easy to develop web pages. 3. PHP processes server-side logic, generates HTML output, and supports user interaction and data processing. 4. PHP can interact with the database, process form submission, and execute server-side tasks.

PHP has shaped the network over the past few decades and will continue to play an important role in web development. 1) PHP originated in 1994 and has become the first choice for developers due to its ease of use and seamless integration with MySQL. 2) Its core functions include generating dynamic content and integrating with the database, allowing the website to be updated in real time and displayed in personalized manner. 3) The wide application and ecosystem of PHP have driven its long-term impact, but it also faces version updates and security challenges. 4) Performance improvements in recent years, such as the release of PHP7, enable it to compete with modern languages. 5) In the future, PHP needs to deal with new challenges such as containerization and microservices, but its flexibility and active community make it adaptable.

The core benefits of PHP include ease of learning, strong web development support, rich libraries and frameworks, high performance and scalability, cross-platform compatibility, and cost-effectiveness. 1) Easy to learn and use, suitable for beginners; 2) Good integration with web servers and supports multiple databases; 3) Have powerful frameworks such as Laravel; 4) High performance can be achieved through optimization; 5) Support multiple operating systems; 6) Open source to reduce development costs.

PHP is not dead. 1) The PHP community actively solves performance and security issues, and PHP7.x improves performance. 2) PHP is suitable for modern web development and is widely used in large websites. 3) PHP is easy to learn and the server performs well, but the type system is not as strict as static languages. 4) PHP is still important in the fields of content management and e-commerce, and the ecosystem continues to evolve. 5) Optimize performance through OPcache and APC, and use OOP and design patterns to improve code quality.

PHP and Python have their own advantages and disadvantages, and the choice depends on the project requirements. 1) PHP is suitable for web development, easy to learn, rich community resources, but the syntax is not modern enough, and performance and security need to be paid attention to. 2) Python is suitable for data science and machine learning, with concise syntax and easy to learn, but there are bottlenecks in execution speed and memory management.

PHP is used to build dynamic websites, and its core functions include: 1. Generate dynamic content and generate web pages in real time by connecting with the database; 2. Process user interaction and form submissions, verify inputs and respond to operations; 3. Manage sessions and user authentication to provide a personalized experience; 4. Optimize performance and follow best practices to improve website efficiency and security.

PHP uses MySQLi and PDO extensions to interact in database operations and server-side logic processing, and processes server-side logic through functions such as session management. 1) Use MySQLi or PDO to connect to the database and execute SQL queries. 2) Handle HTTP requests and user status through session management and other functions. 3) Use transactions to ensure the atomicity of database operations. 4) Prevent SQL injection, use exception handling and closing connections for debugging. 5) Optimize performance through indexing and cache, write highly readable code and perform error handling.

Using preprocessing statements and PDO in PHP can effectively prevent SQL injection attacks. 1) Use PDO to connect to the database and set the error mode. 2) Create preprocessing statements through the prepare method and pass data using placeholders and execute methods. 3) Process query results and ensure the security and performance of the code.

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),
