Wie lade ich Bilder mit einer https-URL in Python 3?

Kann Ihnen helfen,...

Habe ich dieses Skript, aber nie fertig (die endgültige Absicht war damit es läuft alltäglichen automatisch)

Aber nicht die Art von person, verschieben sich die Antworten, hier ist das Stück code, das Ihr Interesse:

    def downloadimg(self):
        import datetime
        imgurl = self.getdailyimg();
        imgfilename = datetime.datetime.today().strftime('%Y%m%d') + '_' + imgurl.split('/')[-1]
        with open(IMGFOLDER + imgfilename, 'wb') as f:
            f.write(self.readimg(imgurl))

Hoffe, es hilft!

Bearbeitet

PS: mit Python ist3

Hier ist die neueste Antwort auf diese Frage, die ich verwendet habe, openCV, um Bilder zu speichern, zusammen mit Anfrage-Modul Auch, es handle batch-Operationen und können Hinzugefügt werden, wie der common code

import numpy as np
from urllib.request import urlopen
import cv2
import os
current_path = os.getcwd()
try: os.mkdir(current_path + "\\Downloaded\\")
except:pass

def downloadImage(url):
    try:
        print("Downloading %s" % (url))
        image_name = str(url).split('/')[-1]
        resp = urlopen(url)
        image = np.asarray(bytearray(resp.read()), dtype="uint8")
        image = cv2.imdecode(image, cv2.IMREAD_COLOR)
        cv2.imwrite(current_path + "\\Downloaded\\" + image_name, image)
    except Exception as error:
        print(error)

if __name__ == '__main__':
    urls = ["https://www.google.com/logos/doodles/2019/st-georges-day-2019-6234830302871552.20-2x.png"]
    for url in urls:
        downloadImage(url)
