[PHP实用接口]身份证,二维码 OCR识别函数

“利用PHP识别是假的，封装的接口到是真的”，emmmm.... 是的，就是这个意思，只不过封装的接口而已...

许久未更新博客，这两个函数之前写东西时搞的，分享出来做做水文吧。

1.身份证识别

接口来自于 腾讯AI开放平台 (免费)，用自己的QQ登录一个平台，然后创建一个应用，审核之后得到app_id和key参数，再配置一下即可使用。

Ps：应用创建之后是需要审核的，大概一天左右吧；如果不想创建，复制下面代码直接用我的也行，但我不保证长期能用哈，所以还是推荐自己搞一个。

参数：card_type代表正反面；

身份证识别代码：

<?php
function get_curl($url, $post = 0, $referer = 0, $cookie = 0, $header = 0, $ua = 0, $nobaody = 0, $async = 0) {
    $ch = curl_init();
    curl_setopt($ch, CURLOPT_URL, $url);
    curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
    curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, false);
    $httpheader[] = "Accept:*/*";
    $httpheader[] = "Accept-Encoding:gzip,deflate,sdch";
    $httpheader[] = "Accept-Language:zh-CN,zh;q=0.8";
    $httpheader[] = "Connection:close";
    curl_setopt($ch, CURLOPT_HTTPHEADER, $httpheader);
    if ($async) {
        curl_setopt($ch, CURLOPT_TIMEOUT, 1);
        curl_setopt($ch, CURLOPT_NOSIGNAL, 1);
        curl_setopt($ch, CURLOPT_AUTOREFERER, 1);
        curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, 5);
    }
    if ($post) {
        curl_setopt($ch, CURLOPT_POST, 1);
        curl_setopt($ch, CURLOPT_POSTFIELDS, $post);
    }
    if ($header) {
        curl_setopt($ch, CURLOPT_HEADER, true);
    }
    if ($cookie) {
        curl_setopt($ch, CURLOPT_COOKIE, $cookie);
    }
    if ($referer) {
        if ($referer == 1) {
            curl_setopt($ch, CURLOPT_REFERER, 'http://m.qzone.com/infocenter?g_f=');
        } else {
            curl_setopt($ch, CURLOPT_REFERER, $referer);
        }
    }
    if ($ua) {
        curl_setopt($ch, CURLOPT_USERAGENT, $ua);
    } else {
        curl_setopt($ch, CURLOPT_USERAGENT, "Mozilla/5.0 (Windows NT 10.0; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/65.0.3325.181 Safari/537.36");
    }
    if ($nobaody) {
        curl_setopt($ch, CURLOPT_NOBODY, 1);
    }
    curl_setopt($ch, CURLOPT_ENCODING, "gzip");
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
    $ret = curl_exec($ch);
    curl_close($ch);
    return $ret;
}

//本站签名算法
function getReqSign($params /* 关联数组 */ , $appkey /* 字符串*/ ) {
    // 1. 字典升序排序
    ksort($params);
    
    // 2. 拼按URL键值对
    $str = '';
    foreach ($params as $key => $value) {
        if ($value !== '') {
            $str .= $key . '=' . urlencode($value) . '&';
        }
    }
    
    // 3. 拼接app_key
    $str .= 'app_key=' . $appkey;
    
    // 4. MD5运算+转换大写，得到请求签名
    $sign = strtoupper(md5($str));
    return $sign;
}

/* 身份证照片识别，API提取自腾讯OCR */
function SFZ_OCR_($path) {
    if (!isset($path))
        return false;
    
    //腾讯AI开放平台
    $app_id = 2113119487;
    $key = 'fWA7BjyR3e4USb2B';
    $api = "https://api.ai.qq.com/fcgi-bin/ocr/ocr_idcardocr";
    
    $post['app_id'] = $app_id;
    $post['time_stamp'] = intval(time());
    $post['nonce_str'] = time();
    $post['card_type'] = 0; //正面
    $post['image'] = base64_encode(file_get_contents($path));
    $post['sign'] = getReqSign($post, $key);
    $ret = get_curl($api, $post);
    return $ret;
}

$path = 'https://open.youtu.qq.com/static/img/icon_id_02.26ed156.jpg';
echo "<img src='$path?" . time() . "' /><br/><br/>";
$ret = json_decode(SFZ_OCR_($path), true);
print_r($ret);

效果图：

简单讲解：get_curl() http请求函数，getReqSign();签名函数【重要】，SFZ_OCR_() 接口请求函数，函数返回的是json，所有需要Json_decode才能看到数组。

2.二维码识别

接口是抓自草料二维码识别，函数传入的二维码URL地址，暂不支持本地二维码。

<?php
/* 二维码图片识别，草料API提取自草料 */
function qrcode_OCR($img) {
    $api = "https://cli.im/apis/up/deqrimg";
    $post = 'img=' . urlencode($img);
    $ch = curl_init();
    curl_setopt($ch, CURLOPT_URL, $api);
    curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
    curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, false);
    $httpheader[] = "X-Requested-With: XMLHttpRequest";
    curl_setopt($ch, CURLOPT_HTTPHEADER, $httpheader);
    curl_setopt($ch, CURLOPT_POST, 1);
    curl_setopt($ch, CURLOPT_POSTFIELDS, $post);
    curl_setopt($ch, CURLOPT_REFERER, 'http://m.qzone.com/infocenter?g_f=');
    curl_setopt($ch, CURLOPT_USERAGENT, "Mozilla/5.0 (Windows NT 10.0; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/65.0.3325.181 Safari/537.36");
    curl_setopt($ch, CURLOPT_ENCODING, "gzip");
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
    $ret = curl_exec($ch);
    curl_close($ch);
    return $ret;
}

$qrcode = 'http://qr.topscan.com/api.php?text=https://qzone.work/';
echo "<img src='$qrcode?" . time() . "' /><br/><br/>";
$ret = json_decode(qrcode_OCR($qrcode), true);
print_r($ret);

效果图：

函数返回同样是 String json，需要json_decode();
