主要用到，帶cookie模擬表單提交和驗證碼識別。

Tesseract-Ocr-For-PHP

把需要執(zhí)行的命令，封裝了一下

直接上腳本，沒進行什么優(yōu)化，簡單了解下：

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',

  curl_setopt($curl, CURLOPT_URL, $login_url);

  curl_close($curl);
  //unlink($cookie_file);
  //unlink('verifyCode.jpg');
  return $result;
}
$count = 0;
// 車牌號

$fdjh = 'xxxxxx';
while (true) {
  $count++;
  if ($count>50) {

    echo '車牌號: '. $car_code.PHP_EOL;
    echo '未處理違章數(shù): '.$info['data']['content']['zs'];
    exit();
  }
}
