微信小程序怎么接入人脸核身？保姆级教程来了

# Python 示例：调用 DetectAuth 获取 BizToken
from tencentcloud.common import credential
from tencentcloud.faceid.v20180301 import faceid_client, models

cred = credential.Credential("SecretId", "SecretKey")
client = faceid_client.FaceidClient(cred, "ap-guangzhou")

def get_biz_token(rule_id, redirect_url):
    req = models.DetectAuthRequest()
    req.RuleId = rule_id
    req.RedirectUrl = redirect_url
    resp = client.DetectAuth(req)
    return resp.BizToken, resp.Url

# 使用示例
rule_id = "你的RuleId"
biz_token, verify_url = get_biz_token(rule_id, "https://your-domain.com/callback")
print(f"BizToken: {biz_token}")

// 引入 SDK
const { init, startVerify } = require('./sdk/huiyan-sdk.min.js')

// 初始化 SDK
init({
  appId: '你的小程序AppId'
})

    bizToken: ''

  // 用户点击开始核身

        }

      // 2. 调用 SDK 启动核身
