Bank based on PHP Card four-element verification API interface calling example

Preliminary preparation

• Application interface

Bank card four-element detection interface application address:https://www.juhe.cn/docs/api/id/213?s=cpphpcn

Self-service application to activate the SMS API and obtain the interface request key. (Currently, the interface only supports enterprise users)

PHP request code example

/**
 * 聚合银行卡四元素校验API发起请求-PHP代码
 * 功能：检测输入的姓名、手机号码、身份证号码、银行卡号是否一致。
 */

// 请求的接口URL
$apiUrl = 'http://v.juhe.cn/verifybankcard4/query';

// 请求参数
$params = [
    'realname' => 'xxx', // 姓名
    'idcard' => 'xxx', // 身份证号码
    'bankcard' => 'xxx', // 银行卡号
    'mobile' => 'xxx', // 手机号码

    'key' => 'xxx', // 接口调用key，通过聚合平台申请开通
];
$paramsString = http_build_query($params);

// 发起接口请求
$response = juheHttpRequest($apiUrl, $paramsString, 1);

// 处理接口返回结果，根据自身业务逻辑修改处理
$paramstring = http_build_query($params);
$content = juheHttpRequest($apiUrl, $paramstring, 1);
$result = json_decode($content, true);
if ($result) {
    if ($result['error_code'] == 0) {
        // 请求成功，根据自身业务逻辑修改处理
        $res = $result['result']['res'];
        if ($res == '1') {
            // 信息核验一致
            echo "信息核验一致";
        } else {
            // 信息核验不一致
            echo "信息核验不一致";
        }
    } else {
        // 请求异常，根据自身业务逻辑修改处理
        echo "{$result['error_code']}:{$result['reason']}" . PHP_EOL;
    }
} else {
    //可能网络异常等问题请求失败，根据自身业务逻辑修改处理
    echo "请求失败";
}

/**
 * 发起网络请求函数
 * @param string $url 请求的URL
 * @param bool $params 请求的参数内容
 * @param int $ispost 是否POST请求
 * @return bool|string 返回内容
 */
function juheHttpRequest($url, $params = false, $ispost = 0)
{
    $httpInfo = [];
    $ch = curl_init();

    curl_setopt($ch, CURLOPT_HTTP_VERSION, CURL_HTTP_VERSION_1_1);
    curl_setopt($ch, CURLOPT_USERAGENT, 'JUHE API');
    curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, 3);
    curl_setopt($ch, CURLOPT_TIMEOUT, 12);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
    if ($ispost) {
        curl_setopt($ch, CURLOPT_POST, true);
        curl_setopt($ch, CURLOPT_POSTFIELDS, $params);
        curl_setopt($ch, CURLOPT_URL, $url);
    } else {
        if ($params) {
            curl_setopt($ch, CURLOPT_URL, $url . '?' . $params);
        } else {
            curl_setopt($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;
}
