看到"插入代码或日志片段"这个按钮了吗？

一个月前也就问过这事呀，多加了参数？

是啊，后来那个需求修改只传一个图片，现在要修改成穿多个图片，就是类似身份证正反面，要拍照后传给服务器

@At("/addpicture")
@Ok("json")
@AdaptBy(type = UploadAdaptor.class, args = { "ioc:myUpload" })
public Object addpicture(@Param("name") String name,
@Param("mobile") String mobile, @Param("number") String number,
@Param("roomid") Integer roomid, @Param("status") Integer status,
@Param("person") Integer person, @Param("pic") List tf)
后台接口参数，其中"tf"z 只能接收到一个图片数据

现在情况是微信小程序前端上传时里面只有一个图片？

每次只传一种的，我印象中

@wendal 兽总，我查一些网上的，想让前台把图片存成为一个数组形式，传给tf后，后台逻辑解析下收到信息

没这种操作的...
