原因

公司小程序需对接微信支付，加载平台证书，使用v3秘钥解码平台证书时报错，我这里使用微信支付 v3 sdk

// 加载平台证书（mchId：商户号,mchSerialNo：商户证书序列号,apiV3Key：V3密钥）AutoUpdateCertificatesVerifier verifier = new AutoUpdateCertificatesVerifier(new WechatPay2Credentials(mchId, new PrivateKeySigner(mchSerialNo, merchantPrivateKey)), apiV3Key.getBytes("utf-8"));

错误代码

解决方案

我这里是要因为公司给到我的v3秘钥错了，更换正确v3秘钥即可
