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

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

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
