Hexo迁移指南：从其他平台无缝迁移到Hexo的完整方案

前言

随着技术博客的发展，许多博主开始从WordPress、Jekyll、Hugo等平台迁移到Hexo。本文将提供一套完整的迁移方案，确保数据完整性和SEO连续性，实现无缝平台迁移。

迁移前准备

1. 数据备份策略

# 创建完整备份
mkdir backup-$(date +%Y%m%d)
cd backup-$(date +%Y%m%d)

# 备份原平台数据
# WordPress示例
mysqldump -u username -p wordpress_db > wordpress_backup.sql
tar -czf uploads_backup.tar.gz /path/to/wordpress/wp-content/uploads/

2. 环境评估清单

文章总数统计
媒体文件大小
自定义字段数量
插件依赖分析
SEO数据备份
评论数据导出

WordPress迁移方案

1. 使用hexo-migrator-wordpress

# 安装迁移插件
npm install hexo-migrator-wordpress --save

# 导出WordPress数据
# 在WordPress后台：工具 -> 导出 -> 所有内容

# 执行迁移
hexo migrate wordpress wordpress-export.xml

2. 自定义迁移脚本

创建scripts/migrate-wordpress.js：

const fs = require('fs');
const path = require('path');
const xml2js = require('xml2js');

class WordPressMigrator {
  async migrate(inputFile, outputDir) {
    const xml = fs.readFileSync(inputFile, 'utf8');
    const parser = new xml2js.Parser();
    const result = await parser.parseStringPromise(xml);
    
    const posts = result.rss.channel[0].item;
    
    for (const post of posts) {
      await this.convertPost(post, outputDir);
    }
  }

  async convertPost(wpPost, outputDir) {
    const title = wpPost.title[0];
    const date = new Date(wpPost['wp:post_date'][0]);
    const content = wpPost['content:encoded'][0];
    const categories = this.extractCategories(wpPost);
    const tags = this.extractTags(wpPost);
    
    const hexoPost = {
      title,
      date: date.toISOString(),
      categories,
      tags,
      content: this.processContent(content)
    };
    
    const filename = `${date.toISOString().split('T')[0]}-${this.slugify(title)}.md`;
    const filepath = path.join(outputDir, filename);
    
    const contentStr = this.formatHexoPost(hexoPost);
    fs.writeFileSync(filepath, contentStr);
  }

  extractCategories(post) {
    return post.category
      ?.filter(cat => cat.$.domain === 'category')
      .map(cat => cat._) || [];
  }

  extractTags(post) {
    return post.category
      ?.filter(cat => cat.$.domain === 'post_tag')
      .map(cat => cat._) || [];
  }

  processContent(content) {
    // 处理WordPress短代码
    content = content.replace(/\[caption.*?\](.*?)\[\/caption\]/g, '$1');
    
    // 处理图片路径
    content = content.replace(
      /src=".*?\/wp-content\/uploads\/(.*?)"/g, 
      'src="/images/$1"'
    );
    
    return content;
  }

  formatHexoPost(post) {
    return `---
title: "${post.title}"
date: ${post.date}
categories: ${JSON.stringify(post.categories)}
tags: ${JSON.stringify(post.tags)}
---

${post.content}`;
  }

  slugify(text) {
    return text.toLowerCase()
      .replace(/[^\w\s-]/g, '')
      .replace(/[\s_-]+/g, '-')
      .replace(/^-+|-+$/g, '');
  }
}

Jekyll迁移方案

1. 文件结构转换

# Jekyll到Hexo目录映射
# Jekyll: _posts/ -> Hexo: source/_posts/
# Jekyll: _layouts/ -> Hexo: themes/your-theme/layout/
# Jekyll: _sass/ -> Hexo: themes/your-theme/source/css/

2. 配置文件转换

创建scripts/migrate-jekyll.js：

const fs = require('fs');
const path = require('path');
const yaml = require('js-yaml');

class JekyllMigrator {
  async migrate(jekyllDir, hexoDir) {
    // 迁移文章
    await this.migratePosts(jekyllDir, hexoDir);
    
    // 迁移配置
    await this.migrateConfig(jekyllDir, hexoDir);
    
    // 迁移静态文件
    await this.migrateAssets(jekyllDir, hexoDir);
  }

  async migratePosts(jekyllDir, hexoDir) {
    const postsDir = path.join(jekyllDir, '_posts');
    const files = fs.readdirSync(postsDir);
    
    for (const file of files) {
      if (file.endsWith('.md')) {
        await this.convertJekyllPost(
          path.join(postsDir, file),
          path.join(hexoDir, 'source/_posts', file)
        );
      }
    }
  }

  async convertJekyllPost(inputPath, outputPath) {
    const content = fs.readFileSync(inputPath, 'utf8');
    const { data, content: body } = this.parseJekyllPost(content);
    
    // 转换Front-matter
    const hexoFrontMatter = {
      title: data.title,
      date: data.date,
      categories: data.categories || [],
      tags: data.tags || [],
      layout: data.layout || 'post'
    };
    
    const hexoContent = this.formatHexoPost(hexoFrontMatter, body);
    fs.writeFileSync(outputPath, hexoContent);
  }

  parseJekyllPost(content) {
    const lines = content.split('\n');
    const frontMatter = [];
    let isFrontMatter = false;
    let contentStart = 0;
    
    for (let i = 0; i < lines.length; i++) {
      if (lines[i] === '---') {
        if (!isFrontMatter) {
          isFrontMatter = true;
        } else {
          contentStart = i + 1;
          break;
        }
      } else if (isFrontMatter) {
        frontMatter.push(lines[i]);
      }
    }
    
    const yamlContent = frontMatter.join('\n');
    const data = yaml.load(yamlContent);
    const body = lines.slice(contentStart).join('\n');
    
    return { data, content: body };
  }

  formatHexoPost(frontMatter, content) {
    const yamlStr = yaml.dump(frontMatter);
    return `---\n${yamlStr}---\n${content}`;
  }
}

Hugo迁移方案

1. 内容格式转换

# Hugo到Hexo内容转换
# Hugo: content/posts/ -> Hexo: source/_posts/
# Hugo: static/ -> Hexo: source/
# Hugo: themes/ -> Hexo: themes/

2. 模板转换工具

创建scripts/migrate-hugo.js：

const fs = require('fs');
const path = require('path');
const toml = require('toml');

class HugoMigrator {
  async migrate(hugoDir, hexoDir) {
    // 迁移内容
    await this.migrateContent(hugoDir, hexoDir);
    
    // 迁移主题
    await this.migrateTheme(hugoDir, hexoDir);
    
    // 迁移配置
    await this.migrateConfig(hugoDir, hexoDir);
  }

  async migrateContent(hugoDir, hexoDir) {
    const contentDir = path.join(hugoDir, 'content');
    await this.processDirectory(contentDir, hexoDir);
  }

  async processDirectory(dir, hexoDir) {
    const items = fs.readdirSync(dir);
    
    for (const item of items) {
      const itemPath = path.join(dir, item);
      const stat = fs.statSync(itemPath);
      
      if (stat.isDirectory()) {
        await this.processDirectory(itemPath, hexoDir);
      } else if (item.endsWith('.md')) {
        await this.convertHugoPost(itemPath, hexoDir);
      }
    }
  }

  async convertHugoPost(inputPath, hexoDir) {
    const content = fs.readFileSync(inputPath, 'utf8');
    const { data, content: body } = this.parseHugoPost(content);
    
    // 转换日期格式
    const date = new Date(data.date);
    const filename = `${date.toISOString().split('T')[0]}-${this.slugify(data.title)}.md`;
    
    // 确定输出目录
    const relativePath = path.relative(path.join(inputPath, '../../'), inputPath);
    const outputDir = path.join(hexoDir, 'source/_posts', path.dirname(relativePath));
    
    if (!fs.existsSync(outputDir)) {
      fs.mkdirSync(outputDir, { recursive: true });
    }
    
    const hexoPost = {
      title: data.title,
      date: date.toISOString(),
      categories: this.extractCategories(data),
      tags: data.tags || [],
      content: body
    };
    
    const outputPath = path.join(outputDir, filename);
    const contentStr = this.formatHexoPost(hexoPost);
    fs.writeFileSync(outputPath, contentStr);
  }

  parseHugoPost(content) {
    const lines = content.split('\n');
    const frontMatter = [];
    let isFrontMatter = false;
    let contentStart = 0;
    
    for (let i = 0; i < lines.length; i++) {
      if (lines[i] === '+++') {
        if (!isFrontMatter) {
          isFrontMatter = true;
        } else {
          contentStart = i + 1;
          break;
        }
      } else if (isFrontMatter) {
        frontMatter.push(lines[i]);
      }
    }
    
    const tomlContent = frontMatter.join('\n');
    const data = toml.parse(tomlContent);
    const body = lines.slice(contentStart).join('\n');
    
    return { data, content: body };
  }

  extractCategories(data) {
    if (data.categories) {
      return Array.isArray(data.categories) ? data.categories : [data.categories];
    }
    return [];
  }

  slugify(text) {
    return text.toLowerCase()
      .replace(/[^\w\s-]/g, '')
      .replace(/[\s_-]+/g, '-')
      .replace(/^-+|-+$/g, '');
  }
}

媒体文件迁移

1. 图片批量迁移

#!/bin/bash
# migrate-images.sh

# WordPress图片迁移
if [ -d "wordpress/wp-content/uploads" ]; then
  echo "迁移WordPress图片..."
  rsync -av wordpress/wp-content/uploads/* source/images/
fi

# Jekyll图片迁移
if [ -d "jekyll/assets/images" ]; then
  echo "迁移Jekyll图片..."
  rsync -av jekyll/assets/images/* source/images/
fi

# Hugo图片迁移
if [ -d "hugo/static/images" ]; then
  echo "迁移Hugo图片..."
  rsync -av hugo/static/images/* source/images/
fi

# 优化图片
npm run optimize:images

2. 图片路径修复

创建scripts/fix-image-paths.js：

const fs = require('fs');
const path = require('path');

function fixImagePaths(postsDir) {
  const files = fs.readdirSync(postsDir);
  
  files.forEach(file => {
    if (file.endsWith('.md')) {
      const filePath = path.join(postsDir, file);
      let content = fs.readFileSync(filePath, 'utf8');
      
      // 修复图片路径
      content = content.replace(
        /!\[.*?\]\((.*?\/wp-content\/uploads\/.*?)\)/g,
        (match, imgPath) => {
          const filename = path.basename(imgPath);
          return `![image](/images/${filename})`;
        }
      );
      
      fs.writeFileSync(filePath, content);
    }
  });
}

fixImagePaths('source/_posts');

SEO迁移策略

1. URL重定向映射

创建source/_redirects（Netlify）：

# WordPress重定向
/blog/:year/:month/:day/:slug /:year/:month/:day/:slug 301

# Jekyll重定向
/:year/:month/:day/:slug.html /:year/:month/:day/:slug 301

# Hugo重定向
/post/:slug /:year/:month/:day/:slug 301

2. 生成重定向规则

// 生成Nginx重定向配置
function generateNginxRedirects(oldUrls, newUrls) {
  const redirects = oldUrls.map((oldUrl, index) => {
    return `rewrite ^${oldUrl}$ ${newUrls[index]} permanent;`;
  });
  
  return redirects.join('\n');
}

数据验证和测试

1. 迁移验证脚本

// 验证迁移结果
class MigrationValidator {
  async validate(sourceDir, targetDir) {
    const results = {
      total: 0,
      success: 0,
      errors: []
    };
    
    const sourceFiles = this.getAllFiles(sourceDir);
    const targetFiles = this.getAllFiles(targetDir);
    
    results.total = sourceFiles.length;
    
    for (const sourceFile of sourceFiles) {
      const targetFile = this.findCorrespondingFile(sourceFile, targetFiles);
      
      if (targetFile) {
        const isValid = await this.validateFile(sourceFile, targetFile);
        if (isValid) {
          results.success++;
        } else {
          results.errors.push(`文件验证失败: ${sourceFile}`);
        }
      } else {
        results.errors.push(`找不到对应文件: ${sourceFile}`);
      }
    }
    
    return results;
  }

  async validateFile(source, target) {
    const sourceContent = fs.readFileSync(source, 'utf8');
    const targetContent = fs.readFileSync(target, 'utf8');
    
    // 验证内容完整性
    const sourceWordCount = sourceContent.split(/\s+/).length;
    const targetWordCount = targetContent.split(/\s+/).length;
    
    return Math.abs(sourceWordCount - targetWordCount) < 100;
  }
}

2. 自动化测试

# GitHub Actions测试工作流
name: Migration Test
on: [workflow_dispatch]

jobs:
  test-migration:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v4
      
      - name: Setup Node.js
        uses: actions/setup-node@v4
        with:
          node-version: '18'
          
      - name: Install dependencies
        run: npm install
        
      - name: Run migration tests
        run: npm run test:migration
        
      - name: Validate migration
        run: node scripts/validate-migration.js

迁移后优化

1. 性能优化

# 清理无用文件
find source/_posts -name "*.backup" -delete
find source/images -name "*.tmp" -delete

# 优化图片
npm run optimize:images

# 构建测试
hexo clean && hexo generate

2. SEO检查

# 检查死链接
npm install -g broken-link-checker
blc https://yourdomain.com -ro

# 验证站点地图
curl https://yourdomain.com/sitemap.xml | xmllint --format -

常见问题解决

1. 编码问题

// 处理编码问题
const iconv = require('iconv-lite');

function fixEncoding(text) {
  // 检测并修复编码
  return iconv.decode(iconv.encode(text, 'utf8'), 'utf8');
}

2. 特殊字符处理

// 处理特殊字符
function sanitizeContent(content) {
  return content
    .replace(/[\u0000-\u001F\u007F-\u009F]/g, '') // 移除控制字符
    .replace(/\u00A0/g, ' ') // 替换不间断空格
    .trim();
}

迁移后检查清单

1. 功能验证

所有文章正常显示
图片正确加载
链接有效
评论系统工作
搜索功能正常
RSS订阅有效

2. SEO验证

站点地图正确
元标签完整
重定向生效
搜索引擎收录正常

结语

平台迁移是一个复杂但值得的过程。通过系统化的迁移方案，你可以确保数据完整性、功能连续性和SEO稳定性。记住，迁移不是终点，而是新旅程的开始。在新的平台上，你将拥有更好的性能、更灵活的定制能力和更丰富的功能。

精心规划，细致执行，让迁移成为博客发展的新起点！
