问题：接口返回信息“平台证书序列号Wechatpay-Serial错误” Wechatpay-Serial字段根据要求也进行了加密，但是一直提示这个错误，也没法校验到底哪出错了。申明一下加密用的是微信支付平台证书序列号，不是商户证书序列号； 请求参数 /// <summary>         /// 添加分账接收方         /// </summary>         /// <param name="account"></param>         /// <param name="name"></param>         /// <param name="relation_type"></param>         /// <returns></returns>         public static string AddReceiver(string account, string name, string relation_type, string public_key)         {             // 敏感信息加密             var enrypt_name = "pUrPcj/7VWvH11fBIE/KcMdt89KEcbnyEEGuVZ74jBGzskgPAaGl9VcF0Eagkx0EcSqWqHSZZy5+D91q2n4yk91jHIrCFEvLk4ZUVfljKvXcyZBZBXZYjjFFba3KoCEOjGFnhCJUHOfqnk0DVCxmqhHKQ6HwhvxhNWPjtrZ8s0PZXn3zrZtCsir3TeqpmqZLTgrIjJRlaJplwFMFl5iYuWJqZT1GTfMAVlRD/QiQTwjuxkPki40PYc/+HHVRiKz+6Jg6r0aHG7KWiM1r/QtUkNyLKKsIfGKMKllo8RJbgce7dz1VDTZah04jMtoxM9DjpnOb5qq6yCqlZjuutrPASQ==";

最近在接入普通服务商通过v3接口发起分账功能，目前已实现了分账的功能，接口是正常调用的，现在想加入添加分账接收方的功能，但是同样的参数，一直提示平台证书序列号Wechatpay-Serial错误，我看了下add和分账的orders接口，公共请求部分都是一样的，为嘛结果不同 [图片][图片]
