thinkphp6解决vue跨域问题

​
在路由处加上allowCrossDomain()就可以了。

跨域请求一般会发送一条OPTIONS的请求&＃xff0c;一旦设置了跨域请求的话&＃xff0c;不需要自己定义OPTIONS请求的路由&＃xff0c;系统会自动加上。

跨域请求系统会默认带上一些Header&＃xff0c;包括&＃xff1a;
Access-Control-Allow-Origin:*
Access-Control-Allow-Methods:GET, POST, PATCH, PUT, DELETE
Access-Control-Allow-Headers:Authorization, Content-Type, If-Match, If-Modified-Since, If-None-Match, If-Unmodified-Since, X-Requested-With

第二种方法&＃xff1a;在入口文件&＃xff08;index.php&＃xff09;加入防跨域代码&＃xff1a;

header(&＃39;Content-Type: text/html;charset&＃61;utf-8&＃39;);
header(&＃39;Access-Control-Allow-Origin:*&＃39;);
header(&＃39;Access-Control-Allow-Methods:POST,GET,OPTIONS,DELETE&＃39;);
header(&＃39;Access-Control-Allow-Credentials: true&＃39;);
header(&＃39;Access-Control-Allow-Headers: Content-Type,Content-Length,Accept-Encoding,X-Requested-with, Origin&＃39;);

第三种方法&＃xff1a;

在这里可以使用tp6的前置中间件

首先开启中间件的文件配置

然后创建一个中间件文件

最后配置

declare (strict_types &＃61; 1);namespace app\middleware;use Closure;
use think\Config;
use think\Request;
use think\Response;class AllowCrossDomain
{protected $COOKIEDomain;// header头配置protected $header &＃61; [&＃39;Access-Control-Allow-Credentials&＃39; &＃61;> &＃39;true&＃39;,&＃39;Access-Control-Max-Age&＃39; &＃61;> 1800,&＃39;Access-Control-Allow-Methods&＃39; &＃61;> &＃39;GET, POST, PATCH, PUT, DELETE, OPTIONS&＃39;,&＃39;Access-Control-Allow-Headers&＃39; &＃61;> &＃39;Authorization, Content-Type, If-Match, If-Modified-Since, If-None-Match, If-Unmodified-Since, X-CSRF-TOKEN, X-Requested-With,token&＃39;,];/*** AllowCrossDomain constructor.* &＃64;param Config $config*/public function __construct(Config $config){$this->COOKIEDomain &＃61; $config->get(&＃39;COOKIE.domain&＃39;, &＃39;&＃39;);}/*** 允许跨域请求* &＃64;access public* &＃64;param Request $request* &＃64;param Closure $next* &＃64;param array $header* &＃64;return Response*/public function handle($request, Closure $next, ?array $header &＃61; []){$header &＃61; !empty($header) ? array_merge($this->header, $header) : $this->header;if (!isset($header[&＃39;Access-Control-Allow-Origin&＃39;])) {$origin &＃61; $request->header(&＃39;origin&＃39;);if ($origin && (&＃39;&＃39; &＃61;&＃61; $this->COOKIEDomain || strpos($origin, $this->COOKIEDomain))) {$header[&＃39;Access-Control-Allow-Origin&＃39;] &＃61; $origin;} else {$header[&＃39;Access-Control-Allow-Origin&＃39;] &＃61; &＃39;*&＃39;;}}return $next($request)->header($header);}
}
