如果你想将切片 y 追加到切片 x 后面,只要将第二个参数扩展成一个列表即可:x = append(x, y...)。 注意: append 在大多数情况下很好用,但是如果你想完全掌控整个追加过程,你可以实现一个这样的 AppendByte 方法: funcAppendByte(slice []byte,data ...byte) []byte {m:=len(slice)n:= m +len(dat...
append 方法总是返回成功,除非系统内存耗尽了。 如果你想将切片 y 追加到切片 x 后面,只要将第二个参数扩展成一个列表即可:x = append(x, y...)。 注意: append 在大多数情况下很好用,但是如果你想完全掌控整个追加过程,你可以实现一个这样的 AppendByte 方法: funcAppendByte(slice []byte,data ...byte...
