How to implement ID card OCR recognition in PHP

Methods to implement ID card OCR recognition: 1. Apply to open the ID card OCR recognition interface and obtain the API request KEY; 2. Call the interface API through "function juhecurl($url,$params=false,$ispost =0){...}", process the data and return the result; 3. Get the content returned by the interface and parse it into an array using json_decode(); 4. Print the return result.

Request parameters

PHP sample code

Please refer to https: //www.sdk.cn/details/vOVl36qOLmlV8E9WXJ

$apiurl="http://apis.juhe.cn/idimage/verify";//请求地址
$key = "";//32位的KEY
$image= "";//图片base64后字符串
$side="front";//正反面
$params=compact('key','image','side');//组合请求参数
$content=juhecurl($apiurl,$params,1);//post请求获取接口返回内容json字符串
$result = json_decode($content,true);//解析成数组
if($result){
    if($result['error_code']=='0'){
        print_r($result);
    }else{
        echo $result['error_code'].":".$result['reason'];
    }
}else{
    echo "请求失败";
}

//网络请求方法
 function juhecurl($url,$params=false,$ispost=0){
        $httpInfo = array();
        $ch = curl_init();
 
        curl_setopt( $ch, CURLOPT_HTTP_VERSION , CURL_HTTP_VERSION_1_1 );
        curl_setopt( $ch, CURLOPT_CONNECTTIMEOUT , 3);
        curl_setopt( $ch, CURLOPT_TIMEOUT , 8);
        curl_setopt( $ch, CURLOPT_RETURNTRANSFER , true );
        if ($params) {
            if (is_array($params)) {
                $paramsString = http_build_query($params);

            curl_setopt( $ch , CURLOPT_URL , $url );
        }
        else
        {
            if($paramsString ){
                curl_setopt( $ch , CURLOPT_URL , $url.'?'.$paramsString);
            }else{
                curl_setopt( $ch , CURLOPT_URL , $url);
            }
        }
        $response = curl_exec( $ch );
        if ($response === FALSE) {
            //echo "cURL Error: " . curl_error($ch);
            return false;
        }
        $httpCode = curl_getinfo( $ch , CURLINFO_HTTP_CODE );
        $httpInfo = array_merge( $httpInfo , curl_getinfo( $ch ) );
        curl_close( $ch );
        return $response;
