关于nextjs中next-sitemap插件生成文件样式丢失问题及自定义样式处理

现象没有默认样式
在这里插入图片描述

修改后

代码配置如下
next-sitemap.config.js如下

// const  { routing } = require('./src/i18n/routing') ;const { flatten } = require('lodash')
const fs = require('fs');
const path = require('path');// 改为硬编码locales值，与routing.ts保持一致
const locales = ['en', 'zh']
module.exports = {siteUrl: process.env.NEXT_PUBLIC_SITE_URL,changefreq: 'weekly',priority: 0.8,sitemapSize: 5000,// generateIndexSitemap: false,transform: async (config, path) => {// 👇 为所有分页文件添加 XSL 声明（包括分页和索引）return {loc: path,lastmod: config.autoLastmod ? new Date().toISOString() : undefined,xsl: '/sitemap-style.xsl'};},// 可选：自定义分页文件名格式filename: 'sitemap-[index].xml',autoLastmod: true, // 从页面文件的修改时间获取generateRobotsTxt: true,exclude: ['/404'// '/admin/*' // 通配符匹配路径],robotsTxtOptions: {policies: [{userAgent: '*', // 所有爬虫allow: '/' // 允许所有路径// disallow: '/private', // 禁止特定路径}],additionalSitemaps: [// process.env.NEXT_PUBLIC_SITE_URL + '/sitemap.xml' // 主站点地图]},// 简化的formatOutput函数，专注于添加样式表引用formatOutput: (sitemapContent) => {console.log('formatOutput正在执行...');// 在XML声明后添加样式表引用const result = sitemapContent.replace('<?xml version="1.0" encoding="UTF-8"?>','<?xml version="1.0" encoding="UTF-8"?>\n<?xml-stylesheet type="text/xsl" href="/sitemap-style.xsl"?>');console.log('formatOutput完成，已添加样式表引用');return result;},additionalPaths: async (config) => {const result = []result.push(locales.map((locale) => {return {loc: process.env.NEXT_PUBLIC_SITE_URL + `/${locale}`,changefreq: 'daily',priority: 1,lastmod: new Date().toISOString(),alternateRefs: locales.filter((targetLocale) => targetLocale === locale).map((targetLocale) => ({href: process.env.NEXT_PUBLIC_SITE_URL + `/${targetLocale}`,hreflang: targetLocale,rel: 'alternate'}))}}) || [])const posts = await fetch(process.env.NEXT_PUBLIC_FETCH_URL + '**************').then((res) => res.json())posts?.data?.map((post) =>result.push(locales.map((locale) => {return {loc: process.env.NEXT_PUBLIC_SITE_URL + `/${locale}/${post.name.toLowerCase()}`,changefreq: 'weekly',priority: 0.8,lastmod: new Date().toISOString(),alternateRefs: locales.filter((targetLocale) => targetLocale === locale).map((targetLocale) => ({href: process.env.NEXT_PUBLIC_SITE_URL + `/${targetLocale}/${post.name.toLowerCase()}`,hreflang: targetLocale,rel: 'alternate'}))}}) || []))const allGames = await fetch(process.env.NEXT_PUBLIC_FETCH_URL + '**************').then((res) => res.json())allGames?.data?.map((post) =>result.push(locales.map((locale) => {return {loc: process.env.NEXT_PUBLIC_SITE_URL + `/${locale}` + '/game/' + `${post.slug}`,changefreq: 'monthly',priority: 0.8,lastmod: new Date().toISOString(),alternateRefs: locales.filter((targetLocale) => targetLocale === locale).map((targetLocale) => ({href: process.env.NEXT_PUBLIC_SITE_URL + `/${targetLocale}` + '/game/' + `${post.slug}`,hreflang: targetLocale,rel: 'alternate'}))}}) || []))return flatten(result)}
}

postbuild.js 处理样式

// 用于处理生成的sitemap文件
const fs = require('fs');
const path = require('path');// 添加站点地图处理逻辑
function processSitemaps() {try {console.log('处理站点地图文件...');const publicDir = path.join(__dirname, 'public');// 确保样式文件存在于public目录const xslSourcePath = path.join(__dirname, 'sitemap-style.xsl');const xslDestPath = path.join(publicDir, 'sitemap-style.xsl');if (fs.existsSync(xslSourcePath)) {fs.copyFileSync(xslSourcePath, xslDestPath);console.log('已复制样式文件到public目录');} else {console.log('警告: 未找到sitemap-style.xsl文件');}// 处理所有站点地图文件const sitemapFiles = fs.readdirSync(publicDir).filter(file => file.startsWith('sitemap') && file.endsWith('.xml'));console.log(`找到 ${sitemapFiles.length} 个站点地图文件`);for (const file of sitemapFiles) {const filePath = path.join(publicDir, file);let content = fs.readFileSync(filePath, 'utf8');if (!content.includes('<?xml-stylesheet')) {console.log(`处理文件: ${file}`);// 替换XML声明，添加样式表引用content = content.replace('<?xml version="1.0" encoding="UTF-8"?>', '<?xml version="1.0" encoding="UTF-8"?><?xml-stylesheet type="text/xsl" href="/sitemap-style.xsl"?>');fs.writeFileSync(filePath, content, {encoding: 'utf8'});console.log(`已更新文件: ${file}`);} else {console.log(`文件 ${file} 已有样式表引用，跳过`);}}console.log('站点地图处理完成');} catch (error) {console.error('处理站点地图文件时出错:', error);}
}// 执行站点地图处理
processSitemaps();

sitemap-style.xsl 样式

<?xml version="1.0" encoding="UTF-8"?>
