### File
文件输入，amis 也默认处理了图片存储，提交给 API 的是文件的下载地址。
用来负责文件上传，文件上传成功后会返回文件地址，这个文件地址会作为这个表单项的值，整个表单提交的时候，其实提交的是文件地址，文件上传已经在这个控件中完成了。
- `type` 请设置成 `file`
- `reciever` 默认 `/api/upload/file` 如果想自己存储，请设置此选项。(PS: 如果想存自己的 bos, 系统配置中可以直接填写自己的 bos 配置。)

如果不希望 File 控件接管上传，可以配置 `asBlob` 或者 `asBase64` 这两个属性（二选一），采用这种方式后，File 控件不再自己上传了，而是直接把文件数据作为表单项的值，文件内容会在 Form 表单提交的接口里面一起带上。
