Why do you need to hide the PHP interface? How to hide?

In today's Internet era, Web applications have become an essential part of every industry. In order to realize data interaction between different software, we often need to use interface technology. However, the sensitive information involved in some interfaces may be used by malicious attackers, so hiding interfaces has become a need for many developers. Here, we will discuss how to hide PHP interfaces with some tricks.

1. Why is it necessary to hide the PHP interface?

The PHP interface is a technology that facilitates network communication. It allows different systems to exchange data and realize information sharing, so it is widely used. Web development in progress. However, data communication implemented through PHP interfaces is easily attacked by adversaries, leading to the leakage of important information. Some hackers will inadvertently add some content that should not appear in the return value of the interface, causing the data to be tampered with.

2. Use the "token" feature to implement interface hiding

When developing PHP interfaces, we often need to add token values ​​​​in the header for interface authentication, and the token authentication mechanism is After the user logs in, a token string with certain rules is generated. Then it is saved in the session or cookie. When the client requests access to the interface through http, it will append this token value to the header, and the server will verify whether the token is correct to determine whether the user is legitimate. So on this basis, we can use the original characteristics of token to expose a few interfaces and hide most interfaces. The process is as follows:

1. Open a small number of interfaces for a certain module, such as login interface, verification code, public interface, etc. These interfaces will omit the logic for determining the validity of the interface.

2. For other interfaces, we force the client to add the token parameter in the header, and the server determines whether the request is legal by verifying whether the token value is legal. Only when the verification is successful, the interface will return data normally.

By hiding the interface in this way, we can effectively prevent external attacks while making the core interface more hidden and secure.

3. Use .htaccess files to hide interfaces

In addition to using token strategies, we can also use .htaccess files to hide PHP interfaces. .htaccess is a configuration file of the Apache web server, which allows the website administrator to control some configurations of the website directory. Through the .htaccess file, we can control the permissions of the access interface, directory protection, URL rewriting and other operations.

In .htaccess, we can configure the path and name of the target interface and hide it behind other conspicuous pages to ensure the security of the access interface.

4. Implement interface hiding through encryption technology

Encryption technology is a relatively common technology for protecting sensitive information. In PHP, encryption algorithms such as md5 are often used to encrypt and store important information. Such information can only obtain its original meaning through a specific decryption algorithm.

In the process of implementing the PHP interface, we can use encryption technology to encrypt the page content to hide the interface. Although this method may increase the processing load on the server, it can ensure the security of core information.

Conclusion

In actual PHP interface development, we must pay attention to interface security and take measures to ensure the concealment of the interface. The above three technologies are all effective solutions to this problem and should be selected based on the actual application scenario. At the same time, during the actual development process, we should continue to learn new technologies to cope with the constant challenges from malicious attackers, improve prevention awareness, and strengthen security.
