How to solve the problem that thinkphp cannot log in to the backend

With the development of the Internet, more and more people have entered the IT industry, and engaging in website development and other related work has become a popular industry. In website development, using frameworks can improve work efficiency and allow for better website maintenance.

Among the commonly used PHP frameworks, thinkphp is efficient, simple and flexible, and is deeply loved by developers. But, how to deal with problems when using thinkphp? This article will take "thinkphp cannot log in to the backend" as an example to introduce related solutions.

First of all, thinkphp is a very excellent PHP framework that can be easily used by both novices and veterans. One of the most common problems in website development is the inability to log in to the backend. This is not only a problem unique to the thinkphp framework, but also encountered in the development of other PHP frameworks. But in thinkphp, the causes and solutions to such problems are different.

Secondly, the user authentication system in the thinkphp framework uses the session mechanism, and the data in the session is saved on the server side. When many users share a server, this leads to mutual interference of sessions, thus This causes the problem of being unable to log in to the backend normally. At this time, different methods need to be used to ensure the security of user authentication.

Here are some solutions:

1. Clear the cache

Clearing the cache can avoid system problems caused by cache. In thinkphp, you can use the system's own function to clear the cache. In the public controller in the demo code, add the following code:

public function _initialize(){
    S([ 'type'=>'File' ]);
    cache('Menus'.session('user.id'), NULL);
}

2. Change the session storage method

Change the session storage method from local storage to a cache server such as Redis for storage. In thinkphp, local storage is used by default. You can modify the following configuration items in the config.php file of the thinkphp framework:

// session支持redis存储模式
'session_type'           => 'redis',
'session_redis_host'     => '127.0.0.1',
'session_redis_port'     => 6379,
'session_redis_auth'     => '',
'session_redis_timeout'  => ''

3. Disable csrf_token

Solution to the thinkphp framework If the user cannot log in to the backend caused by the use of csrf_token, you can add Token configuration in the system public controller:

// 禁用csrf_token
protected $middleware = [
    \think\middleware\SessionInit::class,
    \think\middleware\Token::class
];

The above are several methods to solve the problem that thinkphp cannot log in to the backend. Each method has its own advantages. Disadvantages, when applying, you need to choose a method that suits you based on the actual situation.

In short, thinkphp is an excellent PHP framework that has strong work efficiency for developers, but it will also encounter various problems during use, such as being unable to log in to the backend. The solutions to these problems also require us to continue to explore and research, select and use them according to the actual situation, and continuously improve our development skills.
