代码如下。我通过 Components/Pages/Scrap.tsx console.log 以下错误。

希望你已经解决了这个问题，我和你有同样的问题（GH讨论），也向后端发送了一个URL。
在我的例子中，请求发送到 localhost:5173（Vite 端口正在运行 React 应用程序）。
我的问题是发送原始 URL。我在我的 URL 中添加了一个 encodeURIComponent，之后请求被发送到我的 RTK api 中的指定 URL。
在 api/scrape-api.ts 中将其更改为
scrapeUrl: builder.query<scrapeModel, string>({
query: url => `scrape?url=${encodeURIComponent(url)}`
}）
