URL management in Yii framework: making URLs more friendly

URL management in Yii framework: making URLs more friendly

As a web developer, we often use URLs, which are an integral part of web applications. In daily development, many people may ignore URL management and just regard it as an inevitable existence. However, if you can optimize the URL to make it more user-friendly and easy to understand, then it will become a huge advantage and bring more users and traffic to your application. The URL management function in the Yii framework is the tool that helps you achieve this.

Yii framework is a high-performance PHP framework that provides many efficient functions, including URL management. As a "Web Application Framework", the Yii framework is favored by developers for its design architecture that supports MVC, powerful scalability and excellent performance. In the Yii framework, URL management and optimization are mainly carried out in three aspects.

URL routing

In the Yii framework, URL routing is a very important function. It is responsible for mapping URL requests to corresponding controllers/actions. Through the definition of routing rules, the Yii framework implements the conversion of URLs to controller operations. When a request comes into a Yii application, the application first parses the request into routes. After route resolution is complete, the Yii framework can find the correct controller/action to handle the request and respond accordingly.

For example, when a user visits http://example.com/blog/post/200, it will be parsed as /blog/post/200 routing. The Yii framework will then find the corresponding controller action to handle the request based on the routing rules, that is, the actionPost($id) method in BlogController, and will 200 Passed as a parameter to this method. This rule can be set by the following code:

'urlManager' => [
    'enablePrettyUrl' => true,
    'showScriptName' => false,
    'rules' => [
        'blog/post/<id:d+>' => 'blog/post',
    ],
],

In this rule, enablePrettyUrl indicates enabling a custom URL, showScriptName indicates whether to display script files in the URL,rules is the setting of routing rules. The rule in this example resolves the URL /blog/post/200 to the blog/post action, and treats 200 as its id value.

URL beautification

URL beautification refers to using shorter, more readable URLs instead of long and difficult to understand URLs. By beautifying the URL, you can improve the user experience and website search engine optimization. The Yii framework provides a variety of URL beautification methods, the most commonly used of which is to enable the "pretty URLs" option.

Enabling the "pretty URLs" option can be achieved with the following setting:

'urlManager' => [
    'enablePrettyUrl' => true,
    'showScriptName' => false,
],

This setting will use Yii's UrlManager component to handle URLs. If no rules have been set before, Yii will use pathInfo by default. However, if you want to customize the rules, you need to set the rules in the rules option. For example:

'urlManager' => [
    'enablePrettyUrl' => true,
    'showScriptName' => false,
    'rules' => [
        [
            'class' => 'yiiestUrlRule',
            'controller' => 'api/user',
            'tokens' => [
                '{id}' => '<id:\w+>'
            ],
            'extraPatterns' => [
                'GET search/{sex}' => 'search',
            ],
        ]
    ]
],

This rule defines a RESTful style URL rule, in which class specifies the use of the yiiestUrlRule class as the processing class for this rule. controller specifies the controller that needs to be processed, tokens specifies the parameters and types that can be used in the controller, extraPatterns specifies additional URL rules.

URL caching

URL caching refers to caching URL conversion results in memory to improve the performance of URL parsing. In the Yii framework, URL caching is implemented through the cache component. Starting from Yii2.0, the framework comes with a variety of cache implementations, including files, Redis, Memcached, APC, etc. Using caching components can help us parse URLs quickly and greatly improve website performance.

In Yii framework, URL cache can be configured in the following way:

'cache' => [
    'class' => 'yiicachingFileCache',
],

This configuration will use file cache to store cache data. If you need to use a different type of cache, just change the class option. For example, using Redis cache:

'cache' => [
    'class' => 'yiiedisCache',
    'redis' => [
        'hostname' => 'localhost',
        'port' => 6379,
        'database' => 0,
    ],
],

Summary

In daily web development, URL management is easily ignored, and people tend to focus on the implementation of functions. However, optimizing your URL and making it more user-friendly and easy to understand will not only bring more traffic to your website, but also improve user experience and SEO rankings. The URL management function of the Yii framework is very powerful and easy to configure. It is a very valuable tool for developers who want to improve website performance and enhance user experience.
