问题描述

我想为我的 laravel 项目生成 Dynamic sitemap.我已经在很多网站上搜索过答案.他们中的一些人使用作曲家来描述它.我不知道该怎么做.在其他一些站点中，他们编写代码以循环从 db 获取 url.在我的项目数据库中，我没有保存任何网址.我的项目是一个医生和病人的网站.那么有没有人知道如何编写 php/laravel 代码来生成动态站点地图.?

I want to generate Dynamic sitemap for my laravel project. I had already searched in so many sites for an answer. some of them describes it using composer. I didn't get how to do that. and in some other sites they wrote codes to get urls from db in loops. In my project db I didn't saved any urls. my project is a site for doctor and patients. so is there any one knows how to write php / laravel codes for dynamic sitemap generation.?

编辑

我是 laravel 的新手，所以我对这个作曲家不熟悉.谁能告诉我，如果我从 github 下载 laravel-sitemap-master.zip，我可以在其中提取它并保存在我的项目目录中吗?如果有人请回答这个问题，那将非常有帮助.

I'm a newbie to laravel so i'm just unfamiliar with this composer. can anyone please tell me if i download the laravel-sitemap-master.zip from github where i can extract it and saves in my project directory? it will be so much helpful if anyone please answer this.

推荐答案

将此行添加到您的 routes.php

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

创建新文件appHttpMiddlewaresitemap.php

<?php namespace AppHttpMiddleware;

use Closure;
use CarbonCarbon;
use IlluminateContractsAuthGuard;

class sitemap {

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

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


    /**
     * Handle an incoming request.
     *
     * @param  IlluminateHttpRequest $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resourcesviewssitemap.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>

在文件 appHttpKernel.php 中向受保护的 $middleware 数组添加一个条目

Add an entry to protected $middleware array in the file appHttpKernel.php

'sitemap' => 'AppHttpMiddlewaresitemap'
