From the dict returned by _getexif() using key 'DateTimeOriginal'?
从 _getexif() 使用键“DateTimeOriginal”返回的字典？

I like to use exif-pybecause it's pure-python, does not require compilation/installation, and works with both python 2.x and 3.x making it ideal for bundling with small portable python applications.
我喜欢使用，exif-py因为它是纯 python，不需要编译/安装，并且可以与 python 2.x 和 3.x 一起使用，使其非常适合与小型便携式 python 应用程序捆绑。

Example to get the date and time a photo was taken:
获取照片拍摄日期和时间的示例：
import exifread
with open('image.jpg', 'rb') as fh:
tags = exifread.process_file(fh, stop_tag="EXIF DateTimeOriginal")
dateTaken = tags["EXIF DateTimeOriginal"]
return dateTaken

This has changed slightly in more recent versions of Pillow (6.0+ I believe).
这在最近版本的 Pillow（我相信 6.0+）中略有改变。
They added a public method getexif()that you should use. The previous version was private and experimental (_getexif()).
他们添加了一个getexif()您应该使用的公共方法。以前的版本是私有的和实验性的 ( _getexif())。
from PIL import Image
im = Image.open('path/to/image.jpg')
exif = im.getexif()
creation_time = exif.get(36867)

ExifTags.TAGSis a mapping from tag to tag name. You can use it to create a map of tag names to values.
ExifTags.TAGS是从标签到标签名称的映射。您可以使用它来创建标记名称到值的映射。
On this particular picture, there are a few different "date" properties (DateTime, DateTimeOriginal, DateTimeDigitized) that could be used.
在这张特定的图片上，可以使用一些不同的“日期”属性（DateTime、DateTimeOriginal、DateTimeDigitized）。
import json
from PIL import Image, ExifTags
from datetime import datetime
def main(filename):
image_exif = Image.open(filename)._getexif()
if image_exif:
# Make a map with tag names
exif = { ExifTags.TAGS[k]: v for k, v in image_exif.items() if k in ExifTags.TAGS and type(v) is not bytes }
print(json.dumps(exif, indent=4))
# Grab the date
date_obj = datetime.strptime(exif['DateTimeOriginal'], '%Y:%m:%d %H:%M:%S')
print(date_obj)
else:
print('Unable to get date from exif for %s' % filename)
Output:
输出：
