Ich werde hier nicht näher darauf eingehen, was domänenübergreifend ist. Hier spreche ich hauptsächlich über thinkphp5.1 und spreche zunächst über die allgemeine Lösungsidee , weil das Front-End von mir selbst geschrieben wurde, habe ich in In der axios
-Konfiguration Folgendes eingestellt
withCredentials: true // Cookie bei domänenübergreifender Anfrage sendenaxios
配置中, 我设置了如下
withCredentials: true // 跨域请求时发送cookie
// 创建一个axios const service = axios.create({ baseURL: URL , withCredentials: true, // 跨域请求时发送cookie timeout: 5000 // request timeout })
在后端的配置中,配置的是
header("Access-Control-Allow-Origin: *");
故而抛出了这样一个错误
Access to XMLHttpRequest at 'http://store.ink/admin/me?sid=lbn3mpacfb3k1mbehnk9qh8kf3' from origin 'http://vue-admin-web.ink' has been blocked by CORS policy: The value of the 'Access-Control-Allow-Origin' header in the response must not be the wildcard '*' when the request's credentials mode is 'include'. The credentials mode of requests initiated by the XMLHttpRequest is controlled by the withCredentials attribute.
意思大概为 设置 withCredentials
为 true
时, origin 是不允许为 *
的, origin必须设置为来源的地址
也就是 http://a.com 请求 http://b.com 的时候, http://a.com 必须设置origin 为 http://b.com 才能通过
最后参阅配置如下
$origin = $_SERVER['HTTP_ORIGIN'] ?? '*'; header("Access-Control-Allow-Origin: $origin"); header('Access-Control-Allow-Credentials: true'); header('Access-Control-Allow-Headers: Authorization, Content-Type, If-Match, If-Modified-Since, If-None-Match, If-Unmodified-Since, X-Requested-With'); header('Access-Control-Allow-Methods: GET, POST, PATCH, PUT, DELETE'); header('Access-Control-Max-Age: 1728000');
当然, 为 * 的时候也可以这样
header("Access-Control-Allow-Origin: *"); header('Access-Control-Allow-Headers: Authorization, Content-Type, If-Match, If-Modified-Since, If-None-Match, If-Unmodified-Since, X-Requested-With'); header('Access-Control-Allow-Methods: GET, POST, PATCH, PUT, DELETE'); header('Access-Control-Max-Age: 1728000');
首先 定义个中间件 php think make:middleware CrossDomain
<?php namespace app\http\middleware; use think\Response; class CrossDomain { public function handle($request, \Closure $next) { $origin = $_SERVER['HTTP_ORIGIN'] ?? '*'; header("Access-Control-Allow-Origin: $origin"); header('Access-Control-Allow-Credentials: true'); header('Access-Control-Allow-Headers: Authorization, Content-Type, If-Match, If-Modified-Since, If-None-Match, If-Unmodified-Since, X-Requested-With'); header('Access-Control-Allow-Methods: GET, POST, PATCH, PUT, DELETE'); header('Access-Control-Max-Age: 1728000'); return $next($request); } }
在router.php
中
Route::group('', function (){ .... 这里写路由 .... })->middleware(['CrossDomain']);
然后又有一个新问题
因为如上是走的路由文件,当请求的url
.... public function render(Exception $e) { # 这里来处理跨域问题 $origin = $_SERVER['HTTP_ORIGIN'] ?? '*'; header("Access-Control-Allow-Origin: $origin"); header('Access-Control-Allow-Credentials: true'); header('Access-Control-Allow-Headers: Authorization, Content-Type, If-Match, If-Modified-Since, If-None-Match, If-Unmodified-Since, X-Requested-With'); header('Access-Control-Allow-Methods: GET, POST, PATCH, PUT, DELETE'); header('Access-Control-Max-Age: 1728000'); $type = request()->isAjax() ? 'json' : "html"; $response = \think\response\Json::create([], $type, 200, []); return $response; # response // 在异常处理接管中,必须返回的是一个人response响应, 而不是 `throw new `抛出一个响应 } ...
