tp5之允許跨域請求

一、在app頂層創建文件common\behavior\CronRun.php 寫入以下代碼

 
<?php


namespace app\common\behavior;
 
use think\Exception;
use think\Response;
 
class CronRun
{
    public function run(&$dispatch){
        header("Access-Control-Allow-Origin:*");
        $host_name = isset($_SERVER['HTTP_ORIGIN']) ? $_SERVER['HTTP_ORIGIN'] : "*";
        $headers = [
            "Access-Control-Allow-Origin" => $host_name,
            "Access-Control-Allow-Credentials" => 'true',
            "Access-Control-Allow-Headers" => "x-token,x-uid,x-token-check,x-requested-with,content-type,Host"
        ];
        if($dispatch instanceof Response) {
            $dispatch->header($headers);
        } else if($_SERVER['REQUEST_METHOD'] === 'OPTIONS') {
            $dispatch['type'] = 'response';
            $response = new Response('', 200, $headers);
            $dispatch['response'] = $response;
        }
    }
}

 

二、 添加鈎子事件

在application \tags下寫入

        'app\\common\\behavior\\CronRun'
    ],
    // 模塊初始化
    'module_init'  => [],
    // 操作開始執行
    'action_begin' => [],
    // 視圖內容過濾
    'view_filter'  => [],
    // 日志寫入
    'log_write'    => [],
    // 應用結束
    'app_end'      => [
        'app\\common\\behavior\\CronRun'
    ],
];

  

接下來就可以跨域請求了
