這篇文章主要介紹“PHP curl怎么模擬登錄帶驗證碼的網站”，在日常操作中，相信很多人在PHP curl怎么模擬登錄帶驗證碼的網站問題上存在疑惑，小編查閱了各式資料，整理出簡單好用的操作方法，希望對大家解答”PHP curl怎么模擬登錄帶驗證碼的網站”的疑惑有所幫助！接下來，請跟著小編一起來學習吧！
需求是這樣的，需要登錄帶驗證碼的網站，獲取數據，但是不可能人為一直去記錄數據，想通過自動采集的方式進行，如下是試驗出來的結果代碼！有需要的可以參考下！
<?php
namespace Home\Controller;
use Think\Controller;
class LoginController extends Controller
{

{

}

// echo $content;
curl_close($ch);
if ($url != $headers["url"] && $redirect == false)
{
return $headers["url"];
}
return $content;
}
}登錄以后，就可以使用帶cookie的訪問其他頁面了！
ps：php curl 登錄淘寶
提交上去后顯示為填寫驗證碼，登錄不上去
填寫驗證碼提交：
