[lin-youming]

简要描述

微信支付官方的变更导致目前 新商户想入驻平台 调起支付时报错

模块版本情况

• WxJava 模块名: weixin-java-pay
• WxJava 版本号:4.6.0

详细描述

该方法请求https://api.mch.weixin.qq.com/v3/certificates接口获取平台证书 返回证书不存在 目前因微信官方变更导致新入驻的商户不在支持平台证书模式 转而支持公钥模式
private void autoUpdateCert() throws IOException, GeneralSecurityException {
WxPayV3HttpClientBuilder wxPayV3HttpClientBuilder = WxPayV3HttpClientBuilder.create()
.withCredentials(credentials)
.withValidator(verifier == null ? response -> true : new WxPayValidator(verifier));

//调用自定义扩展设置设置HTTP PROXY对象
HttpProxyUtils.initHttpProxy(wxPayV3HttpClientBuilder,this.wxPayHttpProxy);

//增加自定义扩展点,子类可以设置其他构造参数
this.customHttpClientBuilder(wxPayV3HttpClientBuilder);

CloseableHttpClient httpClient = wxPayV3HttpClientBuilder.build();

HttpGet httpGet = new HttpGet(CERT_DOWNLOAD_PATH);
httpGet.addHeader("Accept", "application/json");

CloseableHttpResponse response = httpClient.execute(httpGet);
int statusCode = response.getStatusLine().getStatusCode();
String body = EntityUtils.toString(response.getEntity());
if (statusCode == HttpStatus.SC_OK) {
  List<X509Certificate> newCertList = deserializeToCerts(apiV3Key, body);
  if (newCertList.isEmpty()) {
    throw new WxRuntimeException("Cert list is empty");
  }
  this.verifier = new CertificatesVerifier(newCertList);
} else {
  log.warn("Auto update cert failed, statusCode = " + statusCode + ",body = " + body);
  throw new WxRuntimeException(this.getErrorMsg(body));
}

}

本项目是否已经支持了微信支付公钥？我看源码好像没有写这方面的东西，只有加载平台证书。
实在不行我们改用微信官方SDK临时规避一下wechatpay-java

测试了下，通过修改重写WxPayConfig类可暂时解决：https://blog.csdn.net/qq_37391200/article/details/143508109

官方给的publicKeyId是带有前缀的吧，看你因为类型转换问题这部分替换掉了，如果没影响是没问题，
