thinkphp5 --- routing problem

In doing thinkphp development projects, met a demand: Let requirements linked sites must end with .html.

The reason: In thinkphp project development, the use of pseudo-static routing format: xxx.com/xxx/2.html, but the latter is the default .html, can also be accessed by visiting xxx.com/xxx/2.

Now requires only be through: xxx.com/xxx/2.html access, that is, the end must have .html 

Solution:

1, or the server apache nginx is configured to redirect.

2, to solve the routing through thinkphp

We can be performed by a method of verifying whether the current route with .html.

To do:

Step 1: Configure routing

':name/:id' => ['index/index/details',['before_behavior'=>'\app\index\behavior\UserCheck']],

Step Two: Custom method was validated

<?php
namespace app\index\behavior;

class UserCheck{
    public function run(){
      $url = request()->url();
      if(!preg_match("/[\w\d]*.html$/",$url)){
        echo "不是以.html结尾的URL";
        // header("HTTP/1.1 404 Not Found");exit;
      }
    }
}
