问题描述
我想构建一个将图像附加到表单数据的功能，但我无法实现此功能。我正在使用 Multer，并且在服务器文件中添加了 express 和 body-parser。
这是控制器功能
structure(list(layer = c(0.0246770934766904,0.0242527868989167,0.0224233190566232,0.0216524802418302,0.022118695762337,0.0209053824836735,0.0211326999515466,0.0217314614023917,0.0226449195846084,0.0264381358128127

当我从邮递员那里调用它时，它给了我未定义的所有数据，错误---
