使用示例的demo无法初始化client

使用例子中的代码无法初始化client {"file":"/Users/apple/business/kuzi-app/common/weixinPay/weixin_pay_client.go:64","func":"kuzi/app/common/weixinPay.NewWeixinPayClient","level":"error","msg":"new wechat pay client err:init client setting err:generate authorization err:you must set privatekey to use SHA256WithRSASigner","time":"2021-09-02T09:09:29+08:00"}

}

//获取商户私钥 func GetPrivateKey() *rsa.PrivateKey { // 加载商户私钥 privateKeyPath := configs.AppConfig.Weixin.MchPrivateKeyPath privateKey, err := utils.LoadPrivateKeyWithPath(privateKeyPath)

请确认下是不是 GetPrivateKey 失败了？
