我对Ride4dApps完全不熟悉，在尝试编写可调用函数时，我不明白i在这里代表@Callable(i)的参数是什么？

1 个解决方案

You need to use @callable(i) to be able to access the data for an invoked function. 您需要使用@callable(i)来访问调用函数的数据。

The parameter i is of type Invocation and basically Invocation is a data structure of: 参数i是Invocation类型，基本上Invocation是一个数据结构：

caller: Address.
payment: Payment|Un, where Payment consist of amount: Long and assetId: ByteVector | Unit.
