怎样防止恶意提交
怎样防止恶意提交
------解决方案--------------------
用session验证。验证码太不人性化了。
或者，提交成功后，header()到一个新网址。
------解决方案--------------------
加验证码、只允许从本站提交。
------解决方案--------------------
提交成功后，header()
------解决方案--------------------
CSDN可以恶意提交吗？
------解决方案--------------------
验证吧，还要ＳＥＳＳＩＯＮ．．．．．ＬＳ的你试下啊
------解决方案--------------------
验证+ session~
------解决方案--------------------
通常有几种办法
1。认证发言，赫赫。
2。通过refrence来判断是否来自该站点的请求
3。验证码。
1比较那个啥。。。。，呵呵，2呢主要问题是哪个refrence可以伪造，3。缺乏人性阿，
各有优缺点吧。
我这么做加上一个系统认证嘛，每天自动一变，内容一样无法提交，连续时间间隔太短不能提交，嗬嗬，看看大家还有什么好办法。
------解决方案--------------------
cookie+timestamp
------解决方案--------------------
加验证码、只允许从本站提交。
这个是没有用的。可以伪造referer的。而且很容易
------解决方案--------------------
一般都是验证码
------解决方案--------------------
连续时间间隔太短不能提交，这个清空cookie后就可以再提交了，最好是写入数据库，先登录，记录最后提交时间，从而判断，要让恶意提交者也麻烦
PHP's Purpose: Building Dynamic WebsitesApr 15, 2025 am 12:18 AMPHP 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: Handling Databases and Server-Side LogicApr 15, 2025 am 12:15 AMPHP 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.
How do you prevent SQL Injection in PHP? (Prepared statements, PDO)Apr 15, 2025 am 12:15 AMUsing 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.
PHP and Python: Code Examples and ComparisonApr 15, 2025 am 12:07 AMPHP and Python have their own advantages and disadvantages, and the choice depends on project needs and personal preferences. 1.PHP is suitable for rapid development and maintenance of large-scale web applications. 2. Python dominates the field of data science and machine learning.
PHP in Action: Real-World Examples and ApplicationsApr 14, 2025 am 12:19 AMPHP is widely used in e-commerce, content management systems and API development. 1) E-commerce: used for shopping cart function and payment processing. 2) Content management system: used for dynamic content generation and user management. 3) API development: used for RESTful API development and API security. Through performance optimization and best practices, the efficiency and maintainability of PHP applications are improved.
PHP: Creating Interactive Web Content with EaseApr 14, 2025 am 12:15 AMPHP makes it easy to create interactive web content. 1) Dynamically generate content by embedding HTML and display it in real time based on user input or database data. 2) Process form submission and generate dynamic output to ensure that htmlspecialchars is used to prevent XSS. 3) Use MySQL to create a user registration system, and use password_hash and preprocessing statements to enhance security. Mastering these techniques will improve the efficiency of web development.
PHP and Python: Comparing Two Popular Programming LanguagesApr 14, 2025 am 12:13 AMPHP and Python each have their own advantages, and choose according to project requirements. 1.PHP is suitable for web development, especially for rapid development and maintenance of websites. 2. Python is suitable for data science, machine learning and artificial intelligence, with concise syntax and suitable for beginners.
The Enduring Relevance of PHP: Is It Still Alive?Apr 14, 2025 am 12:12 AMPHP is still dynamic and still occupies an important position in the field of modern programming. 1) PHP's simplicity and powerful community support make it widely used in web development; 2) Its flexibility and stability make it outstanding in handling web forms, database operations and file processing; 3) PHP is constantly evolving and optimizing, suitable for beginners and experienced developers.
