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：https://github.com/tesseract-ocr/tesseract

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

<?phprequire '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();  }}
