thinkphp5.1跨域问题解决

方法一：在公共控制器里面初始化方法

protected function initialize()
    {
        parent::initialize(); // TODO: Change the autogenerated stub
        header('Access-Control-Allow-Origin:*');
        header('Access-Control-Allow-Methods:GET, POST, PATCH, PUT, DELETE');
        header('Access-Control-Allow-Headers:Authorization, Content-Type, If-Match, If-Modified-Since, If-None-Match, If-Unmodified-Since, X-Requested-With');
        if (request()->isOptions()){
            exit();
        }
    }

方法二：

在入口文件/public/index.php加上

// 跨域访问
header('Access-Control-Allow-Origin:*');
if($_SERVER['REQUEST_METHOD'] == 'OPTIONS'){
    header('Access-Control-Allow-Headers: Authorization, Language, Origin, X-Requested-With, Content-Type, Accept');
    header('Access-Control-Allow-Credentials:true');
    header('Access-Control-Allow-Methods:GET,POST,OPTIONS');
    header('Access-Control-Max-Age:1728000');
    header('Content-Type:text/plain charset=UTF-8');
    header('Content-Length: 0', true);
    header('status: 200');
    header('HTTP/1.0 204 No Content');
    exit;
}else{
    header("Access-Control-Allow-Methods:GET, POST, PUT, DELETE, OPTIONS");
    header("Access-Control-Allow-Headers: Authorization, Language, Origin, X-Requested-With, Content-Type, Accept");
}
