使用php如何扫描url死链接

* 从Packagist上搜索需要的包

https://packagist.org/

* 通过composer下载依赖包

composer require guzzlehttp/guzzle
composer require league/csv

* 使用composer自动加载器, 编写scan.php

<?php

// 1. 使用composer自动加载器
require 'vendor/autoload.php';

use GuzzleHttp\RequestOptions;

// 2. 实例Guzzle HTTP客户端
$client = new \GuzzleHttp\Client();

$options = [
    RequestOptions::TIMEOUT => 3,
    RequestOptions::DECODE_CONTENT => false,
    RequestOptions::HEADERS => [
        'User-Agent' => 'Mozilla/5.0 (Macintosh; Intel Mac OS X 10_11_6) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/67.0.3396.99 Safari/537.36',
    ]
];

// 3. 打开迭代处理csv
// 或者传用户自定义命令行参数指定输入文件 $argv[1]
// $file = new SplFileObject('../data/t_video.csv'); /* $csvRow[4], $csvRow[5] */
$file = new SplFileObject('../data/urls.csv');
$csv = \League\Csv\Reader::createFromFileObject($file);
foreach ($csv as $csvRow) {
    $url = $csvRow[0];
    echo 'scanning ',$url,'... ';
    try {
        // 4. 发送http options请求
        $httpResponse = $client->request('GET', $url, $options);

        // 5. 检查http相应的状态码
        $code = $httpResponse->getStatusCode();
        if ($code === 200) {
            echo "\033[32m[OK]\033[0m",PHP_EOL;
        } else {
            throw new \Exception();
        }

    } catch (\Exception $e) {
        // 6. 把死链发给标准

* input csv:

../data/urls.csv
