如何使用 PHP cURL 检索验证码并保存会话?

更新:已解决

大家好，我知道了，只需保存 cookie到临时文件，并重新提交表格卷曲并使用先前设置 cookie临时文件 :) 感谢大家的回复 :)

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

And for next curl just use CURLOPT_COOKIEFILE like this

/* 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来通过 php curl 提交内容.首先获取会话和验证码，用户必须提交验证码才能最终提交.

i'm create some script to submit content via php curl. first fetch session and captcha, and user must submit captcha to final submit.

问题是我无法获取验证码，我已尝试使用此代码和 preg_match 获取图像标签并返回它

the problem is i can't get captcha, i've try with this code and preg_match to get image tag and return it

    $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/.

But no luck, page i'm trying to submit is http://abadijayaiklan.co.cc/pasang-iklan/.

希望有人能帮帮我:)

感谢和问候

推荐答案

从 curl_setopt 的 php 手册页，CURLOPT_COOKIEFILE 和 CURLOPT_COOKIEJAR 应该两者都指定一个文件名.您将它们设置为1"(这可能是有效的，但这是您想要的吗?)

From the php manual page on curl_setopt, CURLOPT_COOKIEFILE and CURLOPT_COOKIEJAR should both specify a filename. You have them set to '1' (which may be valid, but is that what you intended?)
