我看代码了, 你应该没有理解中间的处理流程. 首先, 多图上传每一项图片的成功失败还是对于整个组件(一次性上传多图)成功失败. 你的钩子也没有考虑到用户使用 async 函数的模式. 并且添加的地方是单个图片处理结束的地方. 图片上传逻辑有做一层代理, 也就是如果连续多次调用图片上传, 那么一定数量内图片上传的请求会合并为一个. 可以详细查看以下几个方法 uploadCatch, originUpload, uploadImg 的处理 |

是单个图片上传完成状态的钩子，用户关心的也应该是单个图片的上传状态。
多图片上传合并为一个请求是底层实现。且如果在这里(uploadCatch)设置钩子，当单次上传文件数量超出 uploadLimit 会多次触发钩子。
这里没太理解什么意思 |

这个需求确实有道理, 就是我感觉你的实现方式并不是很完美. 有些问题可以考虑更细致一点. 那另一个问题, 你想的是提供hook, 为什么不是事件呢? |

这个参考了elementui |
