如何:在Kotlin中启动并忘记异步协同路由

请注意,如果已经不存在特定的协程范围(不是挂起函数,即),则可以使用:

fun Process (item: String): Response {
    GlobalScope.launch {
       ... <YOUR ASYNC (Processing) CODE GOES HERE> ...
    }
    ... <YOUR SYNC CODE GOES HERE> ...
    return Response("Your request for $item is being processed...")
}

但是,例如,当异步部分引发异常时,请小心可能的内存泄漏。扩展CoroutineScope是一种更好的方法。更多信息请访问 https://discuss.kotlinlang.org/t/unavoidable-memory-leak-when-using-coroutines/11603/7 Why not use GlobalScope.launch?

大概 kotlinx.coroutines#launch 或 kotlinx.coroutines#async

launch(CommonPool) {
    for(item in collection){
      val result = apiCall(item);
      log(result);
    }
}

或

for(item in collection){
    launch(CommonPool) {
      val result = apiCall(item)
      log(result)
    }
}
