随着近年来移动互联网的迅速发展，网络安全和信息安全的重要性也日益凸显，各行业对实名认证的要求也越来越严格，身份证OCR识别接口也就应运而生，它可以让用户通过手机摄像头扫描身份证或者上传身份证图像，快速识别并自动填写相关信息，大大提升了用户体验。
以下是身份证OCR 识别 API 接口用如何PHP调用的示例代码：
<?php$appKey = "您的appKey";
$appSecret= "您的appSecret";$url = "https://api.shuxuntech.com/v1/idCard/ocr";
$method = "POST";$timestamp = getUnixTimestamp();
var_dump($timestamp);
$sign = hash('sha256',$appKey . $timestamp . $appSecret);
var_dump($sign);$headers = array();
array_push($headers, "Content-Type" . ":" . "application/x-www-form-urlencoded; charset=UTF-8");
array_push($headers, "appKey" . ":" . appKey);
array_push($headers, "timestamp" . ":" . timestamp);
array_push($headers, "sign" . ":" . sign);$image = "";
$imgUrl = "";
$bodys = "image=" . $image . "&imgUrl=" . $imgUrl;$curl = curl_init();
curl_setopt($curl, CURLOPT_CUSTOMREQUEST, $method);
curl_setopt($curl, CURLOPT_URL, $url);
curl_setopt($curl, CURLOPT_HTTPHEADER, $headers);
curl_setopt($curl, CURLOPT_POSTFIELDS, $bodys);
curl_setopt($curl, CURLOPT_FAILONERROR, false);
curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);if (1 == strpos("$".$url, "https://")) {curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, false);curl_setopt($curl, CURLOPT_SSL_VERIFYHOST, false);
}
var_dump(curl_exec($curl));function getUnixTimestamp () {list($s1, $s2) = explode(' ', microtime());return sprintf('%.0f',(floatval($s1) + floatval($s2)) * 1000);
}
返回的数据：
（1）正面返回
{"code": "0","msg": "成功","isFee": 1,"seqNo": "0harl9qk12a2cav0mmy25uufl3df4uid","data": {"result": 1,"resultDesc": "识别成功，有数据","info": {"side": "front","type": 1,"front": {"birthday": "1990-01-21","address": "杭州市余杭区仓前街道某某小区1幢801室","gender": "男","race": "汉","name": "张三","idCard": "330110199001212311"},"back": null}}
}（2）反面返回
{"code": "0","msg": "成功","isFee": 1,"seqNo": "n2d8oo1qzxhgf9t399lairvfflztkh49","data": {"result": 1,"resultDesc": "识别成功，有数据","info": {"side": "back","type": 1,"front": null,"back": {"issuedBy": "杭州市公安局余杭分局","validDate": "2021.06.21-2041.06.21"}}}
}（3）错误返回
{"code": "1","msg": "参数错误","isFee": 0,"seqNo": null,"data": null
}需要特别注意的是，在使用身份证OCR 识别 API 之前，我们首先需要申请并获取 API Key,不同的平台获取 API Key 的方式可能会有所不同。但是这个 API Key 将作为我们身份验证的凭证，在后续的接口请求中必须携带。
