Python将图像从URL保存到ZipFile

Question

如何将图像从URL保存到zipfile？例如，我试图将this image保存到zipfile，但它不断抛出错误“找不到文件”

我做错了什么

from zipfile import ZipFile
from tempfile import TempFile
import urllib.request

with TemporaryFile() as tf:
    with ZipFile(tf, mode='w') as zf:
        image_url = 'https://upload.wikimedia.org/wikipedia/commons/a/ab/Wurmseegurke.jpg'
        url = urllib.request.open(image_url)
        filename = image_url.split('/')[-1]
        zf.write(filename, url.read())

下面是完整的错误：FileNotFoundError:[Errno 2]没有这样的文件或目录：“Wurmseegurke.jpg”

Answer 1

TemporaryFile在关闭后会被删除，因此您的图像在写入后将不可用。 您需要使用writest（）在zip中创建“文件对象”：

from zipfile import ZipFile
import urllib.request
import os


image_url = 'https://upload.wikimedia.org/wikipedia/commons/a/ab/Wurmseegurke.jpg'
url = urllib.request.urlopen(image_url)
filename = image_url.split('/')[-1]

zipPath = '/tmp/%s.zip' % filename
with ZipFile(zipPath, mode='w') as zf:
    zf.writestr(filename, url.read())
print(os.path.exists(zipPath))  # probing a zip file was written!

输出：

True
