php中使用tesseract识别验证码，并且模拟登录，验证码错误-PHP Chinese Network Q&A

代码如下：

<?php
header("Content-type:text/html;charset=utf-8");
/**
 * 模拟登录
 */

//1.初始化变量
$cookie_file = tempnam('./temp','cookie');
$login_url = "http://210.32.33.91:8080/reader/redr_verify.php";//登录页面
$verify_code_url = "http://210.32.33.91:8080/reader/captcha.php";//验证码页面

//2.获取cookies
echo "正在获取COOKIE...<br>";
$curl = curl_init();
$timeout = 5;
curl_setopt($curl, CURLOPT_URL, $login_url);
curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($curl, CURLOPT_CONNECTTIMEOUT, $timeout);
curl_setopt($curl,CURLOPT_COOKIEJAR,$cookie_file); //获取COOKIE并存储
$contents = curl_exec($curl);
curl_close($curl);
//3.取出验证码
echo "COOKIE获取完成，正在取验证码...<br>";
$curl = curl_init();
curl_setopt($curl, CURLOPT_URL, $verify_code_url);
curl_setopt($curl, CURLOPT_COOKIEJAR, $cookie_file);//保存cookie
curl_setopt($curl, CURLOPT_COOKIEFILE, $cookie_file);//使用cookie
curl_setopt($curl, CURLOPT_HEADER, 0);
curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);
$img = curl_exec($curl);
curl_close($curl);

$codename = time();
$fp = fopen("/home/wwwroot/default/tesseract/Test/images/$codename.png","w");
echo "<img src='./images/$codename.png'>";
fwrite($fp,$img);
fclose($fp);
//开始识别验证码
echo "验证码取出完成，正在休眠，正在识别验证码...<br>";

passthru("/usr/bin/tesseract  /home/wwwroot/default/tesseract/Test/images/$codename.png /home/wwwroot/default/tesseract/Test/images/$codename");
$code = file_get_contents("./images/$codename.txt");

echo "验证码成功取出：$code<br>";

echo "正在准备模拟登录...<br>";

Linux的话captcha目录,cookies目录给写权限
你一步步断点调试,看你那个程序生成的结果是多少,图片是多少,

代码在:https://github.com/rainwsy/sf/tree/master/library-OCR-login

更新:
你应该
1.将验证码存下来,跟文字结果对比下,
2.对比每次的session_id是否一致
3.CURLOPT_COOKIEJAR第一次用的时候存session_id就可以了,后面的操作用CURLOPT_COOKIEFILE来读取session_id,其实你可以对比下几次请求返回header头中的session_id是否一致
我的验证码识别结果:

写了个DEMO:

指出几个问题,获取session在获取验证码的那一步一并获取就OK,没必要先取得session再取验证码,
当看到账号密码隐藏的时候我再想这是给校友回答的吗?
