EOS。生成原始（未签名）交易后意外数量减少，签名并广播

Question

Account 在丛林测试网上。

I. 这是尝试发送 95 EOS 并且在尝试时余额为 102 EOS 的同时加电并购买 ram。结果：得到了足够数量的错误。

II. 这里是尝试发送 30 EOS 并且在尝试时余额为 102 EOS 时加电并购买 ram。结果：减少量约为60 EOS。这次尝试是successful.

但余额意外减少：

发送前是102 EOS
发送后是41.9996 EOS。

x2 似乎在减少（转账是 30，powerup 费用是 0.0002）。

谁能解释一下哪里出了问题，为什么发送数量是 30，减少数量是 60？

提前致谢)

Answer 1

问题出在 serialization/deserialization 部分。使用的库在 DTO 中创建分隔字段 getter 命名模式（例如，有字段 'account' 并且附近还有字段 'getAccount'）。

当原始（未签名）交易被序列化时，它也为“getter”字段创建了json字段。并且原始事务反序列化时，jackson库合并了字段数据和“getter”数据，因此存在重复。

您可以在主题开始 post 中看到原始交易中的重复项（“account”和“getAccount”、“data”和“getData”等）。

在主网上，这需要双重发送，但在测试网上，它就像是“双重支出和一次发送”。

我们在反序列化步骤中使用了下一个修复：

    val objectMapper: ObjectMapper = objectMapper
        .setVisibility(PropertyAccessor.ALL, JsonAutoDetect.Visibility.NONE)
        .setVisibility(PropertyAccessor.FIELD, JsonAutoDetect.Visibility.ANY)

EOS。生成原始（未签名）交易后意外数量减少，签名并广播
