利用Kotlin和协程实现DSL样式的网络请求
场景一个界面有3个网络请求, 默认先进行进度条, 然后并发执行3个网络请求, 在最耗时的网络请求完事, 隐藏进度条.
apiDSL方法中为什么要重复多次创建ViewModelDsl<Response>()
对象呢?抽离出来不更好吗?
protected fun <Response> apiDSL(apiDSL: ViewModelDsl<Response>.() -> Unit) {
val s: ViewModelDsl<Response> = ViewModelDsl<Response>().apply(apiDSL)
api<Response> {
onRequest {
s.request()
}
onResponse {
s.onResponse?.invoke(it)
}
onStart {
val override = s.onStart?.invoke()
if (override == null || !override) {
onApiStart()
}
override
}
onError { error ->
val override = s.onError?.invoke(error)
if (override == null || !override) {
onApiError(error)
}
override
}
onFinally {
val override = s.onFinally?.invoke()
if (override == null || !override) {
onApiFinally()
}
override
}
}
}
