3.2. "Hollywood Principles"Looking at the previous description of the dependency injection concept, we refine the core idea of dependency injection. If the traditional coupling between components, such as new, Factory mode, is a developer's initiative to build dependent objects, then the dependency injection mode is its reverse, that is, passively waiting for som

SQL Injection
SQL injection is a type of attack that causes great harm. Although the attack is very harmful, the defense is far from as difficult as XSS.

Properties of behavior and method of injection principle
We learned from the above that the intent of the act is to inject its own properties and methods into the dependent classes. So how does Yii inject an action-yii\base\behavior attribute and method into a yii\base\component? For attributes, this is done through the __get () and __set () magic methods. For methods, it is through the __call () method.

In general, to inject your own program into other processes, you must use the DLL file. This method has been discussed in the previous article. But in fact, it can be implemented without relying on DLL files. However, this method is not universal and not as flexible as DLL injection, because it needs to write the code into the "injection program". Once the content to be injected changes, you need
I suddenly wondered if we could use any method to bypass the restrictions of SQL injection? I checked on the Internet AND found that most of the methods mentioned are aimed at AND "" AND "=" filtering breakthroughs. Although there are some improvements, there are still some keywords not bypassed, I do not dare to comment on the effect of the above filter because I do not often intrude into the website, but it is certain that the effect will not be ver

With the development of B/s pattern application development, more and more programmers use this pattern to write applications. But because the entry threshold of the industry is not high, the level of programmers and experience is uneven, a large number of programmers in the code, not the user input data to judge the legality, so that the application has security problems. Users can submit a database query code, based on the results returned by the program to obtain some of the dat
