代码执行后出现错误消息

来源：stackoverflow 2024-02-22 09:12:15 0浏览收藏

今日不肯埋头，明日何以抬头！每日一句努力自己的话哈哈~哈喽，今天我将给大家带来一篇《代码执行后出现错误消息》，主要内容是讲解等等，感兴趣的朋友可以收藏或者有更好的建议在评论提出，我都会认真看的！大家一起进步，一起学习！

问题内容

我有一个循环，其中对值进行排序，并对这些值进行比较。如果存在相同的值，则会将它们从同一值数组中删除。之后，我想要执行以下操作，以便代码继续运行直到结束。之后，通知用户这些值（已删除）未被添加。但我编写了代码，因此这会导致进一步代码的执行停止。告诉我如何正确处理，以便即使相同的值满足，代码也能运行到最后，然后才输出有关这些相同值的消息。另外：我给出的结构是json格式，没有重复。但我也想提供发生错误的信息。告诉我如何正确实现这一刻

type Result struct {
        Result  int                        `json:"result"`
        Message string                     `json:"message"`
        Status []string
    }
