ChangeLog

模块：ohos.rpc.IRemoteObject, ohos.rpc.RemoteProxy和ohos.rpc.RemoteObject
接口：sendRequest(code: number, data: MessageParcel, reply: MessageParcel, options: MessageOption): boolean

变更后接口：
sendRequest(code: number, data: MessageParcel, reply: MessageParcel, options: MessageOption): Promise<SendRequestResult>

import rpc from "@ohos.rpc"

let option = new rpc.MessageOption()
let data = rpc.MessageParcel.create()
let reply = rpc.MessageParcel.create()
proxy.sendRequest(1, data, reply, option)
	.then(function(result) {  
		console.info("send request done")
		if (result.errCode === 0) {
			// read result from result.reply
		}
	})
	.catch(function(e) {
		console.error("send request failed: " + e)
	})
	.finally(() => {
		data.reclaim()
		reply.reclaim()
	})
