如何使用 cURL 从页面获取文本

Question

我最近需要制作一个 PHP 文件从页面中获取文本并显示它，但我不知道该怎么做。我当前的代码是：https://pastebin.com/Zhh4SS3L        $results["registeredname"] = "here shall be the domain";    $results["productname"] = "this shall be fetched";    $results["productid"] = "5";    $results["billingcycle"] = "Monthly";    $results["validdomains"] = $this->getHostDomain();    $results["validips"] = $this->getHostIP();    $results["validdirs"] = $this->getHostDir();    $results["checkdate"] = Carbon::now()->toDateString();    $results["version"] = "this shall be fetched";    $results["regdate"] = "this shall be fetched";    $results["nextduedate"] ="this shall be fetched";;    $results["addons"] = array(array('name' => 'Branding Removal', 'nextduedate' => "this shall be fetched";', 'status' 任何建议都很好！

这让我想起去年玩的一个东西。因为我没有您计划获取的确切值。我将向您展示我使用 cURL 进行操作的示例。应该有帮助。

我对我的网站进行了一些更改，所以它可能不再返回任何内容（但谁知道哈哈），但我知道它对我有用，所以重点仍然存在。

它的基本要点是 - 输入一个页面，发布搜索的术语，返回页面上的任何内容。除了您想要的之外，这还将向 URL POST 一个值，但您可以跳过 POST 部分。如果数据是在登录或其他东西后面。

/*

 * TESTING GROUNDS

 *

 * A. Goal: Search (toms.click/search) and return found articles page

 * website = toms.click

 *

 * word to search for (1 match): axiom

 *

 * condition for submit:

 * if (isset($_POST['searchSubmit']) && isset($_POST['searchbar'])) { ... }

 * → ['searchSubmit' => 'GO', 'searchbar' => 'axiom']

 *

 *

 * form layout:

 * <form method="POST" action="https://toms.click/search">

        <input class="search-bar" type="search" name="searchbar" placeholder="Search" minlength="3" title="search the website" required=""><!--

        whitespace removal between searchbar and submit

        --><input class="submit" name="searchSubmit" type="submit" value="Go">

   </form>

 *

/**

 * @param $searchbar string whatever you'd type into the searchbar

 * @return string

 */

function remoteSearch($searchbar)

{

    $url = 'https://toms.click/search'; //The URL of what you want to fetch / enter / post to

    /** @var array $fields what we're going to post, $fields['a'] = 'b' is $_POST['a'] = 'b' */

    $fields = array(

        'searchSubmit' => 'GO',

        'searchbar' => $searchbar

    );

    $ch = curl_init();

    //Set our target url (login script)

    curl_setopt($ch, CURLOPT_URL, $url);

    //Enable post and load a post query

    curl_setopt($ch, CURLOPT_POST, 1);

    curl_setopt($ch, CURLOPT_POSTFIELDS, http_build_query($fields));

    //HTTPs, don't verify it for now

    curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);

    curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, false);

    //Enable up to 10 redirects

    curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true);

    curl_setopt($ch, CURLOPT_MAXREDIRS, 10);

    //We want whatever is on the other side

    curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);

    return curl_exec($ch);

}

你可以用它来轻松抓取东西，所以我想你可以使用它。

希望这可以帮助您或为您指明正确的方向:)
