Qiniu::RS.image_exif(url)
|
||||
|
||||
使用 SDK 提供的 `Qiniu::RS.image_exif` 方法，可以基于一张存储于七牛云存储服务器上的原始图片图片，取到该图片的 EXIF 信息。
|
||||
|
||||
**参数**
|
||||
|
||||
url
|
||||
: 必须，字符串类型（String），原图的下载链接，需是 `Qiniu::RS.get`（或`Qiniu::RS.batch_get`）函数返回值中 `url` 字段的值，或者是 `Qiniu::RS.download`（或`Qiniu::RS.batch_download`）函数返回的下载链接。且文件本身必须是图片。
|
||||
|
||||
**返回值**
|
||||
|
||||
如果参数 `url` 所代表的图片没有 EXIF 信息，返回 `false`。否则，返回一个包含 EXIF 信息的 Hash 结构。
