一，配置api多版本:

1,目录结构: 2,路由: route/app.php

use think\facade\Route;

$arr_version = ["v1","v2"];
 
$uri = request()->server('REQUEST_URI');
$arr_uri = explode("/",$uri);
global $apiVersion;
if (!isset($arr_uri[1]) || trim($arr_uri[1]) == '') {
    $apiVersion = "";
} else {
      $tmpVersion = trim($arr_uri[1]);
      if (in_array($tmpVersion,$arr_version)) {
          $apiVersion = $tmpVersion;
      } else {
          $apiVersion = "";
      }
}
 
//Route::rule($version.'/:controller/:function', $version.'.:controller/:function');
 
Route::group($apiVersion.'/home',function() {
    global $apiVersion;
    Route::get('tabbar',$apiVersion.'.Home/tabbar') ;
    //Route::get('/recent','api/:version.Product/getRecent') ;
});

二，php代码开发:

1,controller/v1/Home.php

<?php
declare (strict_types = 1);
 
namespace app\controller\v1;
 
use app\BaseController;
use app\result\Result;
 
class Home extends BaseController
{
    public function tabBar() {
        $button = [
            ['id'=>1,'name'=>'首页'],
            ['id'=>2,'name'=>'商品列表'],
            ['id'=>3,'name'=>'我的'],
        ];
        return Result::Success(["button"=>$button]);
    }
}

2,controller/v2/Home.php

<?php
declare (strict_types = 1);
 
namespace app\controller\v2;
 
use app\BaseController;
use app\result\Result;
 
class Home extends BaseController
{
    public function tabBar() {
        $button = [
            ['id'=>1,'name'=>'首页'],
            ['id'=>2,'name'=>'商品列表'],
            ['id'=>3,'name'=>'购物车'],
            ['id'=>4,'name'=>'我的'],
        ];
        return Result::Success(["button"=>$button]);
    }
}

三，测试效果:

1,访问:

http://192.168.219.6:8000/v1/home/tabbar

返回: 2,访问:

http://192.168.219.6:8000/v2/home/tabbar

返回:

四，查看php和thinkphp的版本:
