推荐答案

最大的好处就是队列是进程和线程安全的.管道不是:如果两个不同的进程试图读取或写入管道的同一端，则会发生不良情况.队列的抽象级别也比管道更高，这在您的特定情况下可能是优势，也可能不是优势.

The big win is that queues are process- and thread- safe. Pipes are not: if two different processes try to read from or write to the same end of a pipe, bad things happen. Queues are also at a somewhat higher level of abstraction than pipes, which may or may not be an advantage in your specific case.
