Ii. Solution Analysis:
Use pre-processing statements and parameterized queries. The pre-processing statements and parameters are sent to the database server for resolution. The parameters are processed as common characters. This method prevents attackers from injecting malicious SQL statements. You have two options to implement this method:
1. Use PDO:
The Code is as follows:
$ Stmt = $ pdo-> prepare ('select * FROM employees WHERE name =: name ')
(function data) {// someactions});}; return{runLogin:runLogin}; }]); It's not hard to see that, after declaring a custom service, we put the login logic in the previous bloated controller into the UserService , and the code immediately becomes full. 2. Use a custom service:App.controller (' Maincontroller ', [' $scope ', ' UserService ', function ($scope, userservice) {$scope. Onlogin = function(user){userservice.runlogin (user);}; }]);Here's UserService is our custom service, which is injecte
@ Joyqi mentioned in an interview with infoq: in terms of the framework, we introduced the concept of Java injection variables in PHP. Although they are not completely the same, they are also similar. The implementation is actually very simple. It is just a few tips for PHP, But it solves a headache in the PHP project... @ joyqi mentioned in the infoq interview:

Using User (), database (), version () three built-in functions get the account name, database name, database version information, first parameter injected 1 ' and 1=2 Union Select--(--no space between,--there are spaces). The value displayed as the first column of the query results at the beginning of the name is displayed as the value of the second column of the query results at surname.
After you know the display, use User (), data
. This method prevents attackers from injecting malicious SQL statements. You have two options to implement this method:
1. use PDO:
$stmt = $pdo->prepare('SELECT * FROM employees WHERE name = :name');
$stmt->execute(array('name' => $name));
foreach ($stmt as $row) {
// do something with $row
}
2. use mysqli:
$stmt = $dbConnection->prepare('SELECT * FROM employees WHERE name = ?');
$stmt->bind_param('s'
is good to reduce the complexity of the component:

Now, the component only needs to access a service when it is needed, and if it does not, it is not even initialized to conserve resources. The component is highly decoupled. Their behavior, or any other aspect of them, does not affect the components themselves.Our approach to implementation ¶
Phalcon\di is a component that implements the dependency injection function of a service, which is itself a container.

If the data entered by the user is inserted into an SQL query statement without being processed, the application may be vulnerable to SQL injection attacks, as shown in the following example: Problem description:

UNICODE dual-bit encoding, the function ascii () cannot be used to obtain the ASCII code, the function unicode () must be used to return the unicode value, use the nchar function to obtain the corresponding Chinese characters. After learning about the above two points, Do you think Chinese Guesses are actually similar to English? Except for the functions used, you must note that the scope of the solution is larger, and the method is similar.AdvancedAfter reading the introductory and advanced ar
Translate as follows: Developers typically want to display, hide, or otherwise modify the UI based on the current user's identity. You can access the authorization service in the MVC view through dependency injection. To inject the authorization service into the Razor view, use @inject directives, such as @inject Iauthorizationservice Authorizationservice. If you want to have an entitlement service in each view, put the @inject directive in the _viewimports.cshtml file in the views directory. F

Spring container loop dependency includes constructor loop dependency and setter loop dependency, how does the spring container solve the cyclic dependency? Let's start by defining a circular reference class:The processing of cyclic dependencies in spring is divided into 3 cases:

Assembly of the Bean:Piecing a bean inside a spring container is called assembly. When you assemble a bean, you need to tell the container which beans and how the container uses dependency injection to tie them together.The root element of the context definition file is The most basic configuration for a bean consists of the bean's ID and his full name Class name (the whole path of the class). The ID of the Description of the Bean's scope:Beans in spring are singleton mode by default. Always ret

Using the gate class (injecting or using gate façade) allows us to easily check whether a user (the current logged-on user or a specified user) is allowed to manipulate certain things. Check the code as follows:
if (Gate::d enies (' Update-post ', $post)) {Abort (403);}Putting this code in the controller will use a well-defined rule update-post to check whether the currently authenticated user has permission to update
