Kotlin Flow实现多路复用

    @Test
    fun `test select flow`() = runBlocking<Unit> {
        //函数 -》 Flow<协程> -> Flow合并

        val name = "guest"
        coroutineScope {
            listOf(::getUserFromLocal, ::getUserFromLocal2).map { kFunction1 ->     //遍历调用
                //调用反射 需要添加依赖
                //    implementation 'org.jetbrains.kotlin:kotlin-reflect:1.7.0'

                kFunction1.call(name)
            }.map { deferred ->
                flow { emit(deferred.await()) }
            }.merge()   //多个flow合并成一个flow
                .collect { user -> //末端操作符
                    println(user)
                }

        }
