如何在Tasker（Java）中正确使用HMAC-SHA256为字符串签名？

希望我不会因为这个问题而打扰你，这个问题不是很重要，但我几乎被困在了最后一步（我想）。但是，我也不确定我是否正确地完成了整个过程，直到现在为止

我正在尝试使用automation Android应用程序生成需要发送的标头，以执行HTTP GET来检索我的帐户内部钱包余额

这是我迄今为止尝试过的Tasker编码（java）的两个变体

A1:Java函数[Return:key\u secret类或对象：String函数：new
{String}（String）Param:“MY_API_SECRET_KEY”Param:Param:Param:Param:Param:Param:Param:]
A2:Java函数[返回：输入类或对象：字符串函数：新建]
{String}（String）Param:“示例内容”Param:Param:Param:Param:Param:Param:Param:]
A3:Java函数[返回：key\u字节类或对象：key\u秘密函数：getBytes]
{byte[]}（）Param:Param:Param:Param:Param:Param:Param:Param:Param:]
A4:Java函数[返回：输入\字节类或对象：输入函数：getBytes
{byte[]}（）Param:Param:Param:Param:Param:Param:Param:Param:Param:]
A5:Java函数[返回：hmac类或对象：Mac函数：getInstance]
{Mac}（字符串）Param:“HmacSHA256”Param:Param:Param:Param:Param:Param:Param:]
A6:Java函数[返回：secu密钥类或对象：SecretKeySpec函数：新建]

供您参考的有用信息：

• NiceHash：是一个用于加密挖掘的哈希能量销售/提供平台，它有一个API来执行调用（GET、POST、DELETE）来做不同的事情，而不必使用Android应用程序或网站登录。所以，我想从我的帐户中检索内部钱包余额
• Tasker：是一款自动化android应用程序，它基本上是一个“简单”（从简单到困难的项目）编程平台，可以在你的设备上执行不同类型的操作

如果您能帮助我完成上述代码，我将不胜感激；）

谢谢大家!
