众所周知，织梦已经开始收费了，这对国内版权意识增强应该不算坏事，但想要免费使用又不想惹麻烦的站长们就有点麻烦了。

有不少朋友来问，我们 MyCms 支不支持织梦数据迁移，目前我们已经实现一键导入织梦的原文章和商品了，现在简要讲述一下实现过程。

一、连接数据库

要想实现数据的迁移导入，那么先要得到数据库信息，所以我们第一步就要实现填写数据库信息功能。

可以打开织梦网站的 data/common.inc.php 文件对照填写。

单次导入数据字段为执行一次导入多少量的数据，默认100条，这个可以依照自己的服务器来调整。

这一步仅仅是保存数据库信息，别无他用。

附上连接数据库代码

//$this->config 为保存的数据库信息$dedeConnection = array_merge(['driver' => 'mysql','charset' => 'utf8','collation' => 'utf8_unicode_ci','prefix' => $this->config['dede_prefix'],
], $this->config);config(['database.connections.dedecms' => $dedeConnection]);$this->connection = DB::connection('dedecms');

二、导入分类/文章

1.导入文章分类，并明确上下级关系。

public function articleCategory()
{if (!Storage::exists("dede_article_category")) {//导入分类$categories = $this->connection->table('arctype')->get();$catArray = $catParentArray = [];foreach ($categories as $category) {$cid = ArticleCategory::insert(['pid' => 0,'name' => $category->typename,]);$catArray[$category->id] = $cid;$catParentArray[$cid] = $category->topid;}foreach ($catParentArray as $key => $value) {if ($value > 0) {$ac = ArticleCategory::find($key);$ac->pid = $catArray[$value];$ac->save();}}Storage::put("dede_article_category", json_encode($catArray));} else {$catArray = json_decode(Storage::get("dede_article_category"), true);}return $catArray;
}

2.要先明确要导入文章的那些信息，然后对应好自身系统的字段，开始导入。

附上 MyCms 导入的代码给大家参考。

public function article(): JsonResponse
{$date = date('Y-m-d H:i:s');//最后导入ID$lastId = Storage::exists("dede_article_last_id") ? Storage::get("dede_article_last_id") : 0;$articles = $this->connection->table('archives')->leftJoin('addonarticle', 'aid', '=', 'id')->where([['channel', '=', 1],['id', '>', $lastId],])->limit($this->config['batch_number'])->get();$importLog = [];$catArray = $this->articleCategory();foreach ($articles as $article) {$aid = Article::insert(['category_id' => $catArray[$article->typeid],'title' => $article->title,'content' => $article->body,'description' => $article->description,'img' => $article->litpic,'author' => $article->writer,'view' => $article->click,'created_at' => date('Y-m-d H:i:s', $article->senddate),'updated_at' => date('Y-m-d H:i:s', $article->pubdate),]);if ($article->shorttitle) {$meta = ['article_id' => $aid,'meta_key' => 'short_title','meta_value' => $article->shorttitle,];ArticleMeta::insert($meta);}$lastId = $article->id;$tagIds = (new ArticleTag)->insertTags(explode(",", trim($article->keywords, ",")));(new ArticleTagRel)->insertRel($aid, $tagIds);//导入记录$importLog[] = ['type' => '文章','oid' => $article->id,'mid' => $aid,'title' => $article->title,'created_at' => $date,'updated_at' => $date,];}Dedecms::insertAll($importLog);//写入导入最后IDStorage::put("dede_article_last_id", $lastId);return $this->result(true);
}

三、导入商品

导入商品也是一样的道理，就不多少，直接附上代码。

public function goods()
{$date = date('Y-m-d H:i:s');$lastId = Storage::exists("dede_goods_last_id") ? Storage::get("dede_goods_last_id") : 0;$articles = $this->connection->table('archives')->leftJoin('addonshop', 'aid', '=', 'id')->where([['channel', '=', 6],['id', '>', $lastId],])->limit($this->config['batch_number'])->get();$importLog = [];$catArray = $this->goodsCategory();foreach ($articles as $article) {$aid = Goods::insert(['category_id' => $catArray[$article->typeid],'goods_name' => $article->title,'content' => $article->body,'description' => $article->description,'goods_image' => $article->litpic,'view' => $article->click,'shop_price' => $article->trueprice ?: $article->price,'market_price' => $article->price,'created_at' => date('Y-m-d H:i:s', $article->senddate),'updated_at' => date('Y-m-d H:i:s', $article->pubdate),]);if ($article->shorttitle) {$meta = ['goods_id' => $aid,'meta_key' => 'short_title','meta_value' => $article->shorttitle,];GoodsMeta::insert($meta);}$lastId = $article->id;$importLog[] = ['type' => '商品','oid' => $article->id,'mid' => $aid,'title' => $article->title,'created_at' => $date,'updated_at' => $date,];}Dedecms::insertAll($importLog);Storage::put("dede_goods_last_id", $lastId);return $this->result(true);
}

最后导入成功，并记录下来。
