我有问题=“从源“http://127.0.0.1:8000”访问“http://localhost:8000/admin/image-upload/”处的 XMLHttpRequest 已被 CORS 策略阻止：对预检请求的响应未通过访问控制检查：请求的资源上不存在“Access-Control-Allow-Origin”标头。”
这是我的文件： // 创建.jsx
import AuthenticatedLayout from "../../Layouts/AuthenticatedLayout";
// import { FontAwesomeIcon } from "@fortawesome/react-fontawesome";
// import { faAdd } from '@fortawesome/free-solid-svg-icons';
import { useForm, Head } from "@inertiajs/react";

import { Sidebar } from "@/Components/Dashboard/Sidebar";
import HeaderAll from "@/Components/HeaderAll";
export function Create({ auth, categories }) {
const { data, setData, errors, processing, post } = useForm({
title: "",
status: "published",
content: "",
category_id: "",
image: null,
});
const submit = (e) => {
e.preventDefault();
post(route("posts.store"));
// setData("image", null);
};
return (
<>
<HeaderAll user={auth.user} />
<Head title="Creat-Post" />
<Sidebar />
{/* Content */}

</div>
</div>

</>
);
}
export default Create;
这是我的“FormPost”中的 Ckeditor // Ckeditor.jsx
import { CKEditor } from "@ckeditor/ckeditor5-react";
// import { Link } from "@inertiajs/react";
import { ClassicEditor } from "@ckeditor/ckeditor5-editor-classic";

export default function Ckeditor({ data, setData }) {

这是我的后端控制器 //ImageUploadController.php
<?php
namespace App\Http\Controllers;
use Illuminate\Http\Request;
class ImageUploadController extends Controller
{
public function storeImage(Request $request)
{
if ($request->hasFile('upload')) {
$originName = $request->file('upload')->getClientOriginalName();
$fileName = pathinfo($originName, PATHINFO_FILENAME);
$extension = $request->file('upload')->getClientOriginalExtension();
$fileName = $fileName . '_' . time() . '.' . $extension;
$request->file('upload')->move(public_path('upload-image'), $fileName);
$url = asset('upload-image/' . $fileName);
return response()->json(['fileName' => $fileName, 'uploaded' => 1, 'url' => $url]);
// return redirect()->route('image.upload');
}
}
}
我在这里使用 Laravel 和 React JS，请帮我解决这个问题:)
我尝试过更改 Laravel 中的 Cors.php 例如这样：
<?php
return [
/*
|--------------------------------------------------------------------------
| Cross-Origin Resource Sharing (CORS) Configuration
|--------------------------------------------------------------------------
|
| Here you may configure your settings for cross-origin resource sharing
| or "CORS". This determines what cross-origin operations may execute
| in web browsers. You are free to adjust these settings as needed.

|
*/
'paths' => ['api/*', 'sanctum/csrf-cookie'],
'allowed_methods' => ['*'],
'allowed_origins' => **['http://localhost:8000'],**
'allowed_origins_patterns' => [],
'allowed_headers' => ['*'],
'exposed_headers' => [],
'max_age' => 0,
'supports_credentials' => false,
];
在此代码上“ 'allowed_origins' => ['http://localhost:8000'],”
尝试使用 laravel-cors 包，它允许您使用 Laravel 中间件配置发送跨源资源共享标头。
这与以下问题相同： 如何在 Laravel 中启用 CORS？
