我的小程序测试腾讯AI服务--人脸验证，我在云平台下测试没有问题，

我下PHP的接口文件（tencentcloud-sdk-php-master），放在自己的服务器根目录，代码一样，测试通不过。

<?php

require_once '/TCloudAutoLoader.php';   //这里就通不过，提示HTTP 500错误  为什么？？？？？？？

echo 'test';

/**

use TencentCloud\Common\Profile\ClientProfile;

use TencentCloud\Common\Profile\HttpProfile;

use TencentCloud\Common\Exception\TencentCloudSDKException;

use TencentCloud\Iai\V20180301\IaiClient;

use TencentCloud\Iai\V20180301\Models\VerifyFaceRequest;

echo 'test';

 * try {

 *     $cred = new Credential("Axxxxxxvxsdgsdgsdc4", "jxxxxxxxxxxxxxxxxxxxxxxxxxnh");

 *     $httpProfile->setEndpoint("iai.tencentcloudapi.com");

 *       

 *     $clientProfile = new ClientProfile();

 *     $clientProfile->setHttpProfile($httpProfile);

 *     $client = new IaiClient($cred, "ap-chengdu", $clientProfile);

 *     $req = new VerifyFaceRequest();

 *     

 *     $params = '{"Url":"http://118xxxxxxxxxxxxx052.jpg","PersonId":"136xxxxxx52"}';

 *     $req->fromJsonString($params);

 *     $resp = $client->VerifyFace($req);

 *     print_r($resp->toJsonString());

 * }

 * catch(TencentCloudSDKException $e) {

 *     echo $e;

 * }
