手机：华为Mate60

系统：鸿蒙4.0

微信版本：最新

依赖：

implementation 'com.tencent.mm.opensdk:wechat-sdk-android-with-mta:+'

华为Mate60调用微信支付失败（换不起微信APP），后台日志打印：

register app failed for wechat app signature check failed

sendReq failed for wechat app signature check failed

与相关微信客服沟通：提交客服调起数据，查询不到唤起记录

相关代码：

//初始化
api = WXAPIFactory.createWXAPI(requireContext(), bean.wxpaypost.appid)
val intent = requireActivity().intent
api?.handleIntent(intent, this)
//点击支付时跳转微信
val req = PayReq()
req.appId = bean.wxpaypost.appid
req.partnerId = bean.wxpaypost.mch_id
req.prepayId =  bean.wxpaypost.prepay_id
req.packageValue = "Sign=WXPay"
req.nonceStr = bean.wxpaypost.nonce_str
req.timeStamp = bean.wxpaypost.timestamp.toString()
req.sign = bean.wxpaypost.sign
val wxApi = WXAPIFactory.createWXAPI(requireContext(), req.appId)
wxApi.registerApp(req.appId)
wxApi.sendReq(req)

其他手机包括vivo、小米、荣耀（P20，鸿蒙2.0）都正常调起并支付，初步判断鸿蒙4.0有这个问题
