下面是个简单的例子，只是简单的请求一个，如有需要例子或者demo请留言我，或者加入QQ: 846951943

<?php
$api_key = '你的api_key';
$secret_key = '你的secret_key';



//首先先获取access_token  ,因为请求身份证验证接口需要用到 ，请求access_token 有效期是30天 我这里没有保存， 如需要你们可以保存到session中
//获取access_token  返回参数请参考 https://ai.baidu.com/ai-doc/REFERENCE/Ck3djhhu
$access_token = getAccessToken($api_key,$secret_key);

$url = 'https://aip.baidubce.com/rest/2.0/image-classify/v1/realtime_search/similar/add?access_token=' . $access_token;   //入库
//$url = 'https://aip.baidubce.com/rest/2.0/image-classify/v1/realtime_search/similar/search?access_token=' . $access_token;  //检索
//$url = 'https://aip.baidubce.com/rest/2.0/image-classify/v1/realtime_search/similar/delete?access_token=' . $access_token; //删除
//$url = 'https://aip.baidubce.com/rest/2.0/image-classify/v1/realtime_search/similar/update?access_token=' . $access_token;  //更新

$base64 = $_POST['base64'];
//在这个地方处理base64 图片

$brief = [  //存到百度的唯一标识
    'goods_id' => 1
];
$res = request_post($url,['brief' => json_encode($brief), 'image' => $base64,]);
