CURL模拟浏览器

  1. curl 模拟浏览器发起请求,支持 GET 和 POST 方法
function httpRequest($url, $data = '') {
    $header = array(
        'User-Agent: Mozilla/5.0 (Windows NT 6.1; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/73.0.3683.103 Safari/537.36',
        'Accept-Language: zh-CN,zh;q=0.8,en-US;q=0.5,en;q=0.3',
        'Accept-Encoding: gzip, deflate',
    );

    $curl = curl_init();
    curl_setopt($curl, CURLOPT_URL, $url);
    curl_setopt($curl, CURLOPT_ENCODING, 'gzip');
    curl_setopt($curl, CURLOPT_HTTPHEADER, $header);
    curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);
    curl_setopt($curl, CURLOPT_FOLLOWLOCATION, true);
    curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, false);
    curl_setopt($curl, CURLOPT_SSL_VERIFYHOST, false);
    curl_setopt($curl, CURLOPT_CONNECTTIMEOUT, 10);
    curl_setopt($curl, CURLOPT_TIMEOUT, 20);

    if (empty($data) == false) {
        curl_setopt($curl, CURLOPT_POST, true);
        curl_setopt($curl, CURLOPT_POSTFIELDS, $data);
    }

    $data = curl_exec($curl);
    curl_close($curl);

    return $data;
}

2. 获取网页内容并匹配

function httpRequestMatch($url, $regular) {
    $header = array(
        'User-Agent: Mozilla/5.0 (Windows NT 6.1; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/73.0.3683.103 Safari/537.36',
        'Accept-Language: zh-CN,zh;q=0.8,en-US;q=0.5,en;q=0.3',
        'Accept-Encoding: gzip, deflate',
    );

    $curl = curl_init();
    curl_setopt($curl, CURLOPT_URL, $url);
    curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);
    curl_setopt($curl, CURLOPT_FOLLOWLOCATION, true);
    curl_setopt($curl, CURLOPT_ENCODING, 'gzip');
    curl_setopt($curl, CURLOPT_HTTPHEADER, $header);
    curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, false);
    curl_setopt($curl, CURLOPT_SSL_VERIFYHOST, false);
    $data = curl_exec($curl);
    $error = curl_error($curl);
    curl_close($curl);

    if ($error) {
        return [];
    }

    preg_match_all($regular, $data, $matches);

    return $matches;
}
