为什么微信支付平台的下载平台证书的网页，现在连接 不上呢？证书下载工具的链接，也是打开 失败，是什么原因

RSAPublicKeyConfig config = new RSAPublicKeyConfig.Builder() .merchantId(ehisPayInfo.getMerchantId()) .publicKey(ehisPayInfo.getPublicKey()) .publicKeyId(ehisPayInfo.getPublicKeyId()) .privateKey(ehisPayInfo.getPrivateKey()) .merchantSerialNumber(ehisPayInfo.getMchSerialNo()) .apiV3Key(ehisPayInfo.getApiV3Key()) .build(); // 构建service JsapiService service = new JsapiService.Builder().config(config).build(); PrepayResponse response = service.prepay(request); [图片]

还差两个月，微信支付的平台证书就要过期了。为什么还看不到灰度的按钮。之前有个另外的号，是自动给我开启了新旧证书

请问我使用 sdk 调用的下单的时候，总是返回以下错误是怎么回事？publicKeyId[PUB_KEY_ID_0113214043012xxxxxxxxxxx] and serialNumber[7B77373C3A93AA83xxxxxxxxxxxxxxxxxx] are not equal 返回的 Wechatpay-Serial 应该是 publicKeyId 啊，使用下面方式的时候这里传的也是 publicKeyId // 可以根据实际情况使用publicKeyFromPath或publicKey加载公钥 2 Config config = 3 new RSAPublicKeyConfig.Builder() 4 .merchantId("1900007291") //微信支付的商户号 5 .privateKeyFromPath("/Users/yourname/yourpath/apiclient_key.pem") // 商户API证书私钥的存放路径 6 .publicKeyFromPath("/Users/yourname/yourpath/pub_key.pem") //微信支付公钥的存放路径 7 .publicKeyId("PUB_KEY_ID_00000000000000000000000000000000") //微信支付公钥ID 8 .merchantSerialNumber("5157F09EFDC096DE15EBE81A47057A72********") //商户API证书序列号 9 .apiV3Key("F09E**") //APIv3密钥 10 .build(); 为什么下单返回的header里的Wechatpay-Serial变成了序列号，什么原因？之前用的是v2，第一次用v3版本，按道理不会用到平台证书啊。

api证书替换成新的。APIv2密钥 也已经手动作废 为啥退款还是显示 证书已作废

背景：微信支付，之前用的证书，现在换成了公钥。 现象：调用 微信支付分停车-查询车牌服务开通信息（https://api.mch.weixin.qq.com/v3/vehicle/parking/services/find） 接口，请求头 Wechatpay-Serial 是以 PUB_KEY_ID_ 开头的（公钥方式签名），请求成功。但是响应时，Wechatpay-Serial 不是以 PUB_KEY_ID 开头的（证书方式签名），导致签名校验失败。 然而。。。创建停车入场（https://api.mch.weixin.qq.com/v3/vehicle/parking/parkings）接口又是可以的。 错误信息： [AbstractVerifier] publicKeyId[PUB_KEY_ID_0115269xxxxxxxxxxxxxx] and serialNumber[413062816B9738387F610F02BA568E0B6B81968D] are not equal 请求： [图片] 响应： [图片]

微信支付wechatpay-serial 位置支付公钥ID模式如何和证书序列号如何做兼容模式处理？
