在不使用composer的情况下在laravel项目中生成动态站点地图

Question

我想Dynamic sitemap为我的laravel项目生成.我已经在很多网站上搜索了答案.其中一些人用作曲家描述它.我没有得到如何做到这一点.在其他一些网站中,他们编写了代码,以便在循环中从db获取URL.在我的项目数据库中,我没有保存任何网址.我的项目是医生和病人的网站.所以有人知道怎么写php / laravel codes for dynamic sitemap generation.

编辑

我是laravel的新手,所以我对这位作曲家不熟悉.任何人都可以告诉我,如果我从github下载laravel-sitemap-master.zip,我可以提取它并保存在我的项目目录中？如果有人请回答这个问题会非常有用.

将此行添加到routes.php中

Route::get('/sitemap', function()
{
   return Response::view('sitemap')->header('Content-Type', 'application/xml');
});

创建新文件app\Http\Middleware\sitemap.php

<?php namespace App\Http\Middleware;

use Closure;
use Carbon\Carbon;
use Illuminate\Contracts\Auth\Guard;

class sitemap {

    /**
     * The Guard implementation.
     *
     * @var Guard
     */
    protected $auth;

    public function __construct(Guard $auth)
    {
        $this->auth = $auth;
    }


    /**
     * Handle an incoming request.
     *
     * @param  \Illuminate\Http\Request $request
     * @param  \Closure                 $next
     *
     * @return mixed
     */
    public function handle($request, Closure $next)
    {
        if ( !$request->is("sitemap") && $request->fullUrl() != '' && $this->auth->guest() )
        {
            $aSiteMap = \Cache::get('sitemap', []);
            $changefreq = 'always';
            if ( !empty( $aSiteMap[$request->fullUrl()]['added'] ) ) {
                $aDateDiff = Carbon::createFromTimestamp( $aSiteMap[$request->fullUrl()]['added'] )->diff( Carbon::now() );
                if ( $aDateDiff->y > 0 ) {
                    $changefreq = 'yearly';
                } else if ( $aDateDiff->m > 0) {
                    $changefreq = 'monthly';
                } else if ( $aDateDiff->d > 6 ) {
                    $changefreq = 'weekly';
                } else if ( $aDateDiff->d > 0 && $aDateDiff->d < 7 ) {
                    $changefreq = 'daily';
                } else if ( $aDateDiff->h > 0 ) {
                    $changefreq = 'hourly';
                } else {
                    $changefreq = 'always';
                }
            }
            $aSiteMap[$request->fullUrl()] = [
                'added' => time(),
                'lastmod' => Carbon::now()->toIso8601String(),
                'priority' => 1 - substr_count($request->getPathInfo(), '/') / 10,
                'changefreq' => $changefreq
            ];
            \Cache::put('sitemap', $aSiteMap, 2880);
        }
        return $next($request);
    }
}

并创建新的视图文件资源\ views\sitemap.blade.php

<?xml version="1.0" encoding="UTF-8"?>
<urlset xmlns="http://www.sitemaps.org/schemas/sitemap/0.9"
        xmlns:image="http://www.google.com/schemas/sitemap-image/1.1"
        xmlns:video="http://www.google.com/schemas/sitemap-video/1.1">
    @foreach( Cache::get('sitemap') as $url => $params )
    <url>
        <loc>{{$url}}</loc>
        <lastmod>{{$params['lastmod']}}</lastmod>
        <changefreq>{{$params['changefreq']}}</changefreq>
        <priority>{{$params['priority']}}</priority>
    </url>
    @endforeach
</urlset>

在app\Http\Kernel.php文件中为受保护的$ middleware数组添加一个条目

'sitemap' => 'App\Http\Middleware\sitemap'

假设您希望您的网站sitemap.xml文件包含您在数据库中拥有的所有医生和患者的链接,您可以这样做:

在routes.php文件中..

Route::get("sitemap.xml", array(
    "as"   => "sitemap",
    "uses" => "HomeController@sitemap", // or any other controller you want to use
));

在HomeController.php文件中(如果你决定使用HomeController)..

public function sitemap()
{
    $doctors = Doctor::remember(59) // chach this query for 59 minutes
        ->select(["id", "updated_at"]) 
        // you may want to add where clauses here according to your needs
        ->orderBy("id", "desc")
        ->take(50000) // each Sitemap file must have no more than 50,000 URLs and must be no larger than 10MB
        ->get();

    $patients = Patient::remember(59) // chach this query for 59 minutes
        ->select(["id", "updated_at"]) 
        // you may want to add where clauses here according to your needs
        ->orderBy("id", "desc")
        ->take(50000) // each Sitemap file must have no more than 50,000 URLs and must be no larger than 10MB
        ->get();

    $content = View::make('sitemap', ['doctors' => $doctors, 'patients' => $patients]);
    return Response::make($content)->header('Content-Type', 'text/xml;charset=utf-8');
}

在views/sitemap.blade.php文件中..

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

<urlset xmlns="http://www.sitemaps.org/schemas/sitemap/0.9">
@foreach($doctors as $doctor)
    <url>
        <loc>{{ URL::route("doctors.show", [$doctor->id]) }}</loc>
        <lastmod>{{ gmdate(DateTime::W3C, strtotime($doctor->updated_at)) }}</lastmod>
        <changefreq>daily</changefreq>
        <priority>1.0</priority>
    </url>
@endforeach

@foreach($patients as $patient)
    <url>
        <loc>{{ URL::route("patients.show", [$patient->id]) }}</loc>
        <lastmod>{{ gmdate(DateTime::W3C, strtotime($patient->updated_at)) }}</lastmod>
        <changefreq>daily</changefreq>
        <priority>1.0</priority>
    </url>
@endforeach
</urlset>

Answer 3

检查https://github.com/RoumenDamianoff/laravel-sitemap

Laravel 4 的简单站点地图生成器。

Route::get('sitemap', function(){

    // create new sitemap object
    $sitemap = App::make("sitemap");

    // set cache (key (string), duration in minutes (Carbon|Datetime|int), turn on/off (boolean))
    // by default cache is disabled
    $sitemap->setCache('laravel.sitemap', 3600);

    // check if there is cached sitemap and build new only if is not
    if (!$sitemap->isCached())
    {
         // add item to the sitemap (url, date, priority, freq)
         $sitemap->add(URL::to('/'), '2012-08-25T20:10:00+02:00', '1.0', 'daily');
         $sitemap->add(URL::to('page'), '2012-08-26T12:30:00+02:00', '0.9', 'monthly');

         // get all posts from db
         $posts = DB::table('posts')->orderBy('created_at', 'desc')->get();

         // add every post to the sitemap
         foreach ($posts as $post)
         {
            $sitemap->add($post->slug, $post->modified, $post->priority, $post->freq);
         }
    }

    // show your sitemap (options: 'xml' (default), 'html', 'txt', 'ror-rss', 'ror-rdf')
    return $sitemap->render('xml');

});

我用过。效果很好！

更新#1

为了消除混乱，让我们举个例子。

假设我有一个博客表，其中包含id, title,blog

我的路线是，Route::get('blog/{blog}',['as' => 'blog.show', 'uses' => 'Blog@show'];

首先我将获取内容，通过$blogs = DB::table('blog')->get();

$blogs将包含结果。

我会循环，

foreach($blogs as $i)
{
     $sitemap->add(route('blog.show',[$i->title]), '2014-11-11', '1.0','daily');
}

我所有的博客都添加到站点地图中。
