获取exif信息

某些设备拍摄出的照片中包含exif信息，用于记录照片的属性信息和拍摄数据。这些信息可以通过 @exif 来获取，返回格式是JSON格式，目前支持返回的类型包括但不限于以下类型：

• Latitude

• Longitude

• East or West Longitude

• North or South Latitude

• Exif Version

• Date and Time

• Color Space

• Compression

• FlashPixVersion

• GPS Tag Version

• Geodetic Survey Data Used

• Orientation

• Padding

• Resolution Unit

• Software

• X-Resolution

• Y-Resolution

注意：并非每一张图片都包含 exif 信息。如果原图没有 exif信息，当您请求 exif 信息时，会产生空的返回.
