[已解决]RPC传输结构体的问题

刚学go不久，遇到比较奇怪的事情，想请教一下。（另外排版比较挫，见谅） 是这样的 leaderSendAppendEntries里面通过goroutine来执行 rf.sendAppendEntriesRPC(index, &args, &reply)，然后发现这么传的话args到了RequestAppendEntiresRPC里面总是nil。 但是通过rf.sendAppendEntriesRPC(index, argsOutsize, &reply)的方式来发送，也就是从goroutine外传输argsOutsize指针，就没什么问题，这个是什么原因呢？ `func (rf *Raft) leaderSendAppendEntries(cmd interface{}){` argsOutsize := AppendEntriesRPCArgs{...} go func(rf *Raft, index int, argsOutsize *AppendEntriesRPCArgs, result []bool) { for { reply := AppendEntriesRPCReply{} args := AppendEntriesRPCArgs{ Term: rf.currentTerm, LeaderId: rf.me, PrevLogIndex: rf.nextIndex[index] - 1, PrevLogTerm: rf.log[rf.nextIndex[index]-1].(logContent).Term, LeaderCommit: rf.commitIndex, Entries: make([]interface{}, 0), } if cmd != nil { (args).Entries = append(args.Entries, rf.log[args.PrevLogIndex+1:]...) } ok := rf.sendAppendEntriesRPC(index, &args, &reply) //ok := rf.sendAppendEntriesRPC(index,argsOutsize , &reply) } }(rf, index, &argsOutsize , result) } } ```func (rf *Raft) sendAppendEntriesRPC(server int, args *AppendEntriesRPCArgs, reply *AppendEntriesRPCReply) bool {``` ok := rf.peers[server].Call("Raft.RequestAppendEntiresRPC", args, reply) return ok }
