验证码图像和卷曲 + php

发布于 2024-08-27 18:47:09 字数 372 浏览 6 评论 0原文

$page = $curl->post($baseUrl.'/submit.php', array('url'=>$address,'phase'=>'1','randkey'=>$randKey[0],'id'=>'c_1'));
$exp = explode('recaptcha_image',$page);

尽管如果我 echo $page; 将会显示网页，但令人惊讶的是，即使是recpatcha div（带有图像本身），也找不到 id recaptcha_image。 Curl 不应该加载用于验证码的图像，但不知怎的，当我尝试找到 div 时，它不在那里。有没有办法捕获 recaptcha 图像的 url？

原文

$page = $curl->post($baseUrl.'/submit.php', array('url'=>$address,'phase'=>'1','randkey'=>$randKey[0],'id'=>'c_1'));
$exp = explode('recaptcha_image',$page);

The id recaptcha_image is not found although if i echo $page; the webpage will be displayed and surprisingly even the recpatcha div (with the image itself). Curl shouldn't load the image for recaptcha but somehow it does though when i try to find the div, it is not there. Is there a way to capture the url of the recaptcha image?

您需要使用像 PHP Simple HTML DOM Parser 这样的 HTML 解析器。
然后类似这样的事情就会起作用：

<?php
$page = $curl->post($baseUrl.'/submit.php', array('url'=>$address,'phase'=>'1','randkey'=>$randKey[0],'id'=>'c_1'));
$html->load($page);
$ret = $html->find('script[src^=http://api.recaptcha.net/]',0);
$src = $ret->src;
//I'm not sure how you get an url with your library, so this might or might not work
$page = $curl->get($src);
preg_match("%challenge\ :\ '([a-zA-Z0-9-_]*)',%", $page, $matches);
$img = "http://api.recaptcha.net/image?c=".$matches[1];
?>

首先获取页面，解析它的脚本 URL，然后打开该 URL 进行挑战，然后将其附加到 URL 本身。图像将位于 $img 变量中。

You'll want to use an HTML parser like this PHP Simple HTML DOM Parser.
Something like this will work then:

<?php
$page = $curl->post($baseUrl.'/submit.php', array('url'=>$address,'phase'=>'1','randkey'=>$randKey[0],'id'=>'c_1'));
$html->load($page);
$ret = $html->find('script[src^=http://api.recaptcha.net/]',0);
$src = $ret->src;
//I'm not sure how you get an url with your library, so this might or might not work
$page = $curl->get($src);
preg_match("%challenge\ :\ '([a-zA-Z0-9-_]*)',%", $page, $matches);
$img = "http://api.recaptcha.net/image?c=".$matches[1];
?>

This first fetches the page, parses it for the script URL, then opens that URL for the challenge which is then appended to the URL itself. The image will be in the $img variable.
