Next.js路由中间件与next-intl国际化配置问题求助

在Next.js与Laravel环境中，需实现以下需求：当用户没有IncomeController Cookie时，禁止直接输入URL访问受保护页面，同时结合next-intl实现国际化路由。

当前遇到的困境：

• 单独使用next-intl中间件：路由国际化正常，但无法实现路由保护
• 单独使用鉴权中间件：路由保护生效，但国际化功能失效
• 将两者整合后出现错误，无法正常运行

整合后报错的中间件代码 #

import { NextResponse } from "next/server";
import { isPathStartsWithBackSlash } from "./app/utils/checkUrlTypes";
import createMiddleware from "next-intl/middleware";

const locales = ["en", "mm", "jp"];
const defaultLocale = "mm";
const i18nMiddleware = createMiddleware({ locales, defaultLocale });

export function middleware(request) {
  const pathName = request.nextUrl.pathname;
  console.log("pathName", pathName);
  // Internationalization logic (using next-intl)
  i18nMiddleware(request); // Execute internationalization middleware first

  // Authentication logic
  if (isPathStartsWithBackSlash(pathName)) {
    const cookies = request.headers.get("cookie");
    const hasCookie = cookies && cookies.includes("IncomeController");
    if (!hasCookie) {
      console.log("no cookie");
      return NextResponse.redirect(new URL("/404", request.url));
    }
  }

  // Continue with the default behavior
  return NextResponse.next();
}

export const config = {
  matcher: ["/", "/(mm|jp|en)/:path*"],
};

仅国际化正常但无路由保护的代码 #

//TODO ADD route middleware for internationalization
import createMiddleware from "next-intl/middleware";
import { NextResponse } from "next/server";

let locales = ["en", "mm", "jp"];

const middleware = createMiddleware({
  // Add locales you want in the app
  locales: ["en", "mm", "jp"],

  // Default locale if no match
  defaultLocale: "mm",
});

export default middleware;

export const config = {
  // Match only internationalized pathnames
  matcher: ["/", "/(mm|jp|en)/:path*"],
};

仅路由保护正常但无国际化的代码 #

import { NextResponse } from 'next/server';
import { isPathStartsWithBackSlash } from './libs/checkUrlTypes'

export function middleware(request) {
  const pathName = request.nextUrl.pathname

  // Check if the requested URL matches a protected route
  if (isPathStartsWithBackSlash(pathName)) {
    // Check if the cookie exists in the request headers
    const cookies = request.headers.get('cookie');
    const hasCookie = cookies && cookies.includes('IncomeController');
    if (!hasCookie) {
      // If the cookie is not present, redirect to the unauthorized page
      return NextResponse.redirect(new URL('/404', request.url));
    }
  }
  // If the request doesn't match a protected route or the user is authenticated, continue with the default behavior
  return NextResponse.next();
}

export const config = {
  matcher: ['/:path*'],
};
