应该加在 <form> 上吧

来自美丽的 NutzCN

前端用的vue,没有form啊....

用了@AdaptBy(type = WhaleAdaptor.class) 是不报Caused by: org.nutz.mvc.upload.UploadException: Unknow Content-Type : application/x-www-form-urlencoded这个了,但是文件参数还是null

VUE 不熟,总之,你提交的 <form> 必须加那个属性,否则得不到。这个是 HTTP 的标准
你搜搜 VUE 相关的解决方法咯,肯定有其他人碰到这个问题的

又妄想用ajax上传文件?

@wendal 似乎vue都是Ajax提交。。。

vue核心没有ajax哦,都是扩展库的事,你需要找的是ajaxfileupload,百度谷歌欢迎你

webupload,七牛,也是不错的选择

@thekingdk 我想问一下 用vue 最后咋解决的。。

@wendal element-ui 自带的 文件上传可以吗
