【问题描述】:
我希望这是一个简单的问题。我想不通为什么它会这样做。无论如何,使用 NextJS,我正在尝试使用 useRouter 挂钩访问路由器中的参数,并将其与 querystring 插件组合以拆分 asPath,因为如果使用无状态,NextJS 不允许您访问路由器的查询部分。这是我的代码:
import { useRouter } from 'next/router';
import queryString from "query-string";
const withPageRouter = (router) => {
router.query = { ...queryString.parse(router.asPath.split(/\?/)[1]) };
return router;
};
function getRouterParams(){
const router = useRouter();
router = withPageRouter(router);
return router;
}
export async function getTown() {
const town = await getRouterParams();
return town;
}
现在当我尝试运行它时,我得到了这个错误:
Server Error
Error: Invalid hook call. Hooks can only be called inside of the body of a function component. This could happen for one of the following reasons:
1. You might have mismatching versions of React and the renderer (such as React DOM)
2. You might be breaking the Rules of Hooks
3. You might have more than one copy of React in the same app
See https://reactjs.org/link/invalid-hook-call for tips about how to debug and fix this problem.
This error happened while generating the page. Any console logs will be displayed in the terminal window.

但在我看来应该没问题;它在函数体中吗?我觉得我错过了一些明显的东西。感谢您的帮助。

@Man of Action 是正确的。您需要将路由器直接导入为
import router from "next/router"
