「新建验证」后，可获得 APPID、App Secret Key

开发文档

云 API 密钥

新建密钥

前端接入

略过

服务器接入

1. 点击右上方 PHP SDK 使用说明 ,下载 sdk 。
2. 填入参数调试，复制自动生成的代码。

实践

比如我将 sdk 下载到了 laravel/sdk 目录

DEMO

<?php

            $resp_json = $resp->toJsonString();
            $resp_array = json_decode($resp_json, true);

            if($resp_array['CaptchaCode'] == 1){
                return true;
            }else{
                Log::error($resp_json);
                return false;
            }

        }
        catch(TencentCloudSDKException $e) {
            Log::error($e);
            return false;
        }
    }
}
