Guzzle使用以快手去水印为例

Guzzle 是个 PHP 框架，解决了发送大量 HTTP 请求和创建 web 服务客户端的问题,是php爬虫的一大必备杀器!

安装

composer.phar require guzzlehttp/guzzle:~6.0

基础常用

请求页面返回html

//引入
    require './vendor/autoload.php';
    use GuzzleHttp\Client;
    $client = new Client();
    //GET方式请求链接
    $response = $client->request('GET','http://www.baidu.com');
 //获取html代码
    $html = $response->getBody()->getContents();
    echo $html;

要注意，这样返回的结果就是你在该链接右键查看网站源代码所获得的代码，后期用js加载出来的内容你并不能直接获取

//匹配任意标签及表情内元素内容
preg_match('/<video[^>]*([\s\S]*?)<\/video>/', $html, $match);
preg_match('/src="(.*?)"/i', $match[0], $match1);

重定向获取重定向的链接

$originalUrl=$client->get($url, [
            'headers'         => $headers,
            'query'           => $query,
            'allow_redirects' => false,
        ]);

使用Guzzle发送一个POST请求JSON

对于Guzzle 5& 6你这样做：

use GuzzleHttp\Client;

$client = new Client();

$response = $client->post('url', [
    'json' => ['foo' => 'bar']
]);

如何读取 Guzzle 的 Response 响应结果中的 JSON 数据

$client = new \GuzzleHttp\Client();

# 获取一个外部 API 接口：
$response = $client->get('http://api.map.baidu.com/geocoder/v2/?callback=renderReverse&location=39.87186,116.479723&output=json&pois=1&ak=Your_AK');
json_decode($response->getBody());

报错非string类型此object或array时

json_decode($response->getBody()->getContents());

举例说明

            	],
            'allow_redirects' => false,
        ]);
        echo("<pre>");
        $url=$response->getHeaders();
        $url=$url['Location'][0];
        var_dump($url);
		$response = $client->get($url,['headers'=>[
            'User-Agent' => "Mozilla/5.0 (Linux; Android 8.0.0; Pixel 2 XL Build/OPD1.170816.004) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/70.0.3538.25 Mobile Safari/537.36",
        ]]);
		// echo("<pre>");
		// var_dump($response->getBody());
		$html=$response->getBody()->getContents();
		preg_match('/<video[^>]*([\s\S]*?)<\/video>/', $html, $match);
		preg_match('/src="(.*?)"/i', $match[0], $match1);
		preg_match('/poster="(.*?)"/i', $match[0], $match2);
		preg_match('/alt="(.*?)"/i', $match[0], $match3);
		var_dump($match1);
		var_dump($match2);
		var_dump($match3);
		
	}
