这篇文章主要介绍了关于使用php如何扫描url死链接,有着一定的参考价值,现在分享给大家,有需要的朋友可以参考一下

* 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 &#39;vendor/autoload.php&#39;;

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 => [
        &#39;User-Agent&#39; => &#39;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&#39;,
    ]
];

// 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(&#39;../data/t_video.csv&#39;); /* $csvRow[4], $csvRow[5] */
$file = new SplFileObject(&#39;../data/urls.csv&#39;);
$csv = \League\Csv\Reader::createFromFileObject($file);
foreach ($csv as $csvRow) {
    $url = $csvRow[0];
    echo &#39;scanning &#39;,$url,&#39;... &#39;;
    try {
        // 4. 发送http options请求
        $httpResponse = $client->request(&#39;GET&#39;, $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. 把死链发给标准输出
        // echo $url.PHP_EOL;
        echo "\033[31m[ERROR]\033[0m ".$e->getMessage().PHP_EOL;
    }
}

* input csv:

../data/urls.csv

output:

 * 在Linux终端输出带颜色的文字的方法

  注意 echo "" 要用双引号, 单引号会原样输出 \033[32mxxx\033[0m

一、shell下的实现方法

只要设置输出属性,就可输出带颜色的文字 ,shell中的部分属性:

      \033[0m 关闭所有属性
      \033[1m 设置高亮度
      \033[4m 下划线
      \033[5m 闪烁
      \033[7m 反显
      \033[8m 消隐
      \033[30m 至 \33[37m 设置前景色
      \033[40m 至 \33[47m 设置背景色
      \033[nA 光标上移n行 
      \033[nB 光标下移n行
      \033[nC 光标右移n行
      \033[nD 光标左移n行
      \033[y;xH设置光标位置
      \033[2J 清屏
      \033[K 清除从光标到行尾的内容
      \033[s 保存光标位置 
      \033[u 恢复光标位置
      \033[?25l 隐藏光标
      \033[?25h 显示光标

      各数字所代表的颜色如下:
      字背景颜色范围:40----49
      40:黑
      41:深红
      42:绿
      43:黄色
      44:蓝色
      45:紫色
      46:深绿
      47:白色

  字颜色:30----39
      30:黑
      31:红
      32:绿
      33:黄
      34:蓝色
      35:紫色
      36:深绿 
      37:白色

      使用,如:echo -e "\033[34mHello, world!" (-e作用是引导设置输出属性),

      恢复属性为默认值:echo -e  "\033[0m",

      同类的多种设置项可以组合在一起,中间用分号(;)隔开。如下:

      echo -e "\033[20;1H\033[1;4;34mHello,world\033[0m"
