轻松实现织梦网站数据迁移到新站点

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ID
    Storage::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。
