在 laravel 项目中生成动态站点地图而不使用作曲家
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'
