Bytom信息上链教程( 二 ) _请求

响应参数：
{"status": "success","data": {"tx_id": "5ef27b930646d468bbb436d3406972ff201aa63702518f777e31dd6a2147dddc"}}
?
用上面返回的tx_id去比原的浏览器中去查看交易详情，就可以查看到我们上传的数据

上面的代码只是build-一个步骤，另外sign-和-请求需要自己去组织参数进行请求。请求完- 获得返回的交易hash,去区块链浏览器上查看自己的上链信息，区块链浏览器地址：:8082/ 。
好了，通过以上的4个步骤，我们就可以借助比原链实现信息上链。如果你有什么疑问或者不明白，请在我们的社区联系我们，。
