php - 如何检索验证码并使用 PHP cURL 保存 session ？

Question

更新:已解决

Hi all, i've got it, just save cookie to temp file, and resubmit form with curl and set cookies with previous temp file :) thanks all for respond :)

这是我的工作代码

$ch = curl_init();
        curl_setopt($ch, CURLOPT_URL, $url_register);  
        curl_setopt($ch, CURLOPT_USERAGENT, $this->useragent);
        curl_setopt($ch, CURLOPT_COOKIEJAR, $this->cookie); 
        curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);
        curl_setopt($ch, CURLOPT_RETURNTRANSFER,1);    
        $out['result']  = curl_exec($ch); 
        $out['error']   = curl_error($ch);
        $out['info']    = curl_getinfo($ch);
        curl_close($ch);

对于下一个 curl，只需像这样使用 CURLOPT_COOKIEFILE

/* fetch captcha url with existed cookie */
            $ch = curl_init($captcha_url);
            curl_setopt($ch, CURLOPT_USERAGENT, $this->useragent);
            curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);
            curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); 
            curl_setopt($ch, CURLOPT_COOKIEFILE, $this->cookie); 
            curl_setopt($ch, CURLOPT_FILE, $fp); 
            $out2['result'] = curl_exec($ch);
            $out2['error']  = curl_error($ch);
            $out2['info']   = curl_getinfo($ch);
            curl_close($ch);

大家好，

我正在创建一些脚本以通过 php curl 提交内容。首先获取 session 和验证码，用户必须提交验证码才能最终提交。

问题是我无法获取验证码，我已经尝试使用此代码和 preg_match 来获取图像标签并将其返回

    $ch = curl_init();

 curl_setopt($ch, CURLOPT_URL,$url);  
 curl_setopt($ch, CURLOPT_USERAGENT, 'Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8.1.2) Gecko/20070219 Firefox/2.0.0.2');
 curl_setopt($ch, CURLOPT_HEADER, 0);
 curl_setopt($ch, CURLOPT_COOKIE, 1);
 curl_setopt($ch, CURLOPT_COOKIEJAR, "1");
 curl_setopt($ch, CURLOPT_COOKIEFILE, "1");
 curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER,1);    
    $result = curl_exec($ch);  
    curl_close($ch);

但运气不好，我要提交的页面是 http://abadijayaiklan.co.cc/pasang-iklan/ .

我希望有人能帮助我:)

感谢和问候

在 curl_setopt 的 php 手册页中，CURLOPT_COOKIEFILE 和 CURLOPT_COOKIEJAR 都应该指定一个文件名。您将它们设置为“1”(这可能是有效的，但这是您想要的吗？)
