PHP脚本自动识别验证码查询汽车违章

经常有查下自己的车有没有违章，所以写了现在这个脚本，帮助查询自己的车是否违章。

主要用到，带cookie模拟表单提交和验证码识别。

tesseract-ocr

验证码识别技术，tesseract-ocr：

安装教程：

tesseract-ocr-for-php

把需要执行的命令，封装了一下

直接上脚本，没进行什么优化，简单了解下：

php

<?php
require 'tesseractocr.php';
function weizhang($car_code, $fdjh)
{
  $shanghui = mb_substr($car_code, 0, 1, 'utf-8');
  $pre = array(
    '冀' => 'he',
    '云' => 'yn'
  );
  $url_pre = $pre[$shanghui];
  $headers = array(
    'host: '.$url_pre.'.122.gov.cn',
    'origin: http://'.$url_pre.'.122.gov.cn',
    'referer: http://'.$url_pre.'.122.gov.cn/views/inquiry.html?q=j',
    'user-agent: mozilla/5.0 (macintosh; intel mac os x 10_12_1) applewebkit/537.36 (khtml, like gecko) chrome/50.0.2661.75 safari/537.36 qqbrowser/4.1.4132.400'
  );
  //初始化变量
  $cookie_file = 'cookie.txt';
  $login_url = "http://$url_pre.122.gov.cn/views/inquiry.html?q=j";
  $post_url = "http://$url_pre.122.gov.cn/m/publicquery/vio";
  $verify_code_url = "http://$url_pre.122.gov.cn/captcha?nocache=".time();
  $curl = curl_init();
  $timeout = 5;
  curl_setopt($curl, curlopt_url, $login_url);
  curl_setopt($curl, curlopt_returntransfer, 1);
  curl_setopt($curl, curlopt_httpheader, $headers);
  curl_setopt($curl, curlopt_connecttimeout, $timeout);
  curl_setopt($curl, curlopt_cookiejar, $cookie_file); //获取cookie并存储
  $contents = curl_exec($curl);
  curl_close($curl);
  $curl = curl_init();
  curl_setopt($curl, curlopt_url, $verify_code_url);
  curl_setopt($curl, curlopt_cookiefile, $cookie_file);
  curl_setopt($curl, curlopt_httpheader, $headers);
  curl_setopt($curl, curlopt_returntransfer, 1);
  $img = curl_exec($curl);
  curl_close($curl);
  $fp = fopen("verifycode.jpg", "w");
  fwrite($fp, $img);
  fclose($fp);
  $code = (new tesseractocr('verifycode.jpg'))->psm(7)->run();
 $code = explode("\n", $code);
 $code = $code[1];
  echo $code.php_eol;
  if (strlen($code) != 4) {
    return json_encode(array('code'=>500));
  }
  $data = array(
    'hpzl'=>'02',
    'hphm1b' => substr($car_code, -6),
    'hphm' => $car_code,
    'fdjh' => $fdjh,
    'captcha' => $code,
    'qm' => 'wf',
    'page' => 1
  );
  $curl = curl_init();
  curl_setopt($curl, curlopt_url, $post_url);
  curl_setopt($curl, curlopt_returntransfer, 1);
  curl_setopt($curl, curlopt_postfields, $data);
  curl_setopt($curl, curlopt_httpheader, $headers);
  curl_setopt($curl, curlopt_cookiefile, $cookie_file);
  $result = curl_exec($curl);
  curl_close($curl);
  //unlink($cookie_file);
  //unlink('verifycode.jpg');
  return $result;
}
$count = 0;
// 车牌号
$car_code = '冀dxxxxx';
// 发动机后6位
$fdjh = 'xxxxxx';
while (true) {
  $count++;
  if ($count>50) {
    exit('查询失败');
  }
  $res = weizhang($car_code, $fdjh);
  $info = json_decode($res, true);
  echo $res.php_eol;
  if ($info['code'] == 200) {
    echo '车牌号: '. $car_code.php_eol;
    echo '未处理违章数: '.$info['data']['content']['zs'];
    exit();
  }
}

执行效果
