Laravel POST 请求 Cors 没有“Access-Control-Allow-Origin”

Laravel POST request Cors No 'Access-Control-Allow-Origin'

提问by kalenpw

Currently receiving an error message when I attempt to POST to a given url. GET works fine on the same domain here is my error:

当我尝试 POST 到给定的 url 时，当前收到一条错误消息。GET 在同一个域上工作正常，这是我的错误：

Access to XMLHttpRequest at 'http://localhost:8000/api/users/login' from origin 'http://localhost:8080' has been blocked by CORS policy: Response to preflight request doesn't pass access control check: No 'Access-Control-Allow-Origin' header is present on the requested resource.

CORS 策略阻止了在“ http://localhost:8000/api/users/login”处访问 XMLHttpRequest来自源“ http://localhost:8080”：对预检请求的响应未通过访问控制检查：否请求的资源上存在“Access-Control-Allow-Origin”标头。

I've found countless questions documenting this same issue all with variations of modify my Cors middleware.

我发现无数问题记录了同样的问题，所有这些问题都包含修改我的 Cors 中间件的变体。

Currently my CORS middleware looks like this:

目前我的 CORS 中间件如下所示：

class Cors
{
    public function handle($request, Closure $next)
    {
        if ($request->isMethod('OPTIONS')) {
            $response = Response::make();
        } else {
            $response = $next($request);
        }
        return $response
            ->header('Access-Control-Allow-Origin', '*')
            ->header('Access-Control-Allow-Methods', 'GET, POST, PUT, DELETE, OPTIONS')
            ->header('Access-Control-Allow-Headers', 'Content-Type, Accept, Authorization, X-Requested-With, Application');
    }
}

The error states No 'Access-Control-Allow-Origin' which I believe my ->header('Access-Control-Allow-Origin', '*')should handle since the * is a wild card from my understanding. Is there a different issue at play here I'm missing? Stack is Laravel backend with VueJS front end using Axios for HTTP requests if that is relevant.

错误指出 No 'Access-Control-Allow-Origin' 我相信我->header('Access-Control-Allow-Origin', '*')应该处理它，因为 * 是我理解的通配符。我错过了这里有什么不同的问题吗？Stack 是 Laravel 后端，VueJS 前端使用 Axios 进行 HTTP 请求（如果相关的话）。

Edit: This question is unique in that I already have the headers suggested in most answers specifically:

编辑：这个问题是独一无二的，因为我已经在大多数答案中特别推荐了标题：

->header('Access-Control-Allow-Origin', '*')
->header('Access-Control-Allow-Methods', 'GET, POST, PUT, DELETE, OPTIONS')

and am still getting the error.

并且仍然收到错误。
