【问题描述】：
我们制作了一个程序，它通过 tkinter GUI 接受输入并转到谷歌图像，并根据输入下载图像。代码如下：
import requests
import bs4
import random
from PIL import Image
from tkinter import messagebox as msgbox
i=0
import os
from tkinter import *
from tkinter import filedialog
ac=str(random.randint(1,20))
b=str(random.randint(20,38))
y=Tk()
def find_file():
aaa=filedialog.askdirectory()
return aaa
def create_folder():
ad=find_file()
global ac
global b
ads=os.path.join(ad,f"Img{ac}{b}")
os.mkdir(ads)
return ads
defe=Entry(bg="white")
defe.grid(row=2,column=2)
adj=Label(text="Enter the name of the photo(s) you want to download :")
adj.grid(row=2,column=1)
ack=Label(text="How many photos you want to download?")
ack.grid(row=3,column=1)
dee=Entry(bg="white")
dee.grid(row=3,column=2)
def download_images():
defei=defe.get()
deee=int(dee.get())
aadgc=[]
play=True
if " gif" in defei or ".gif" in defei:
msgbox.showerror("GIF not supported",".gif format is not supported by this software.Sorry for the inconvenience")
play=False
while play:
asd=create_folder()
for start in range(0,400,20):
bararara=f"https://www.google.co.in/search?q={defei}&source=lnms&tbm=isch&start={start}#imgrc=fTslNdnf0RRRxM"
a=requests.get(bararara).text
soup=bs4.BeautifulSoup(a,"lxml")
ab=soup.find_all("img",{"class":"n3VNCb"},limit=deee)
aadgc.extend(ab)
aa=[abb["src"] for abb in aadgc]
for source in aa:
r=random.randint(0,100)
ra=random.randint(0,1000)
raa=asd+"\\"+str(r)+str(ra)+".png"
try:
binary=requests.get(source).content
except requests.exceptions.MissingSchema:
binary=requests.get("http:"+source).content
except:
binary=requests.get("https:"+source).content
with open(raa,"wb") as saaho:
saaho.write(binary)
saaho.close()
global i
i+=1
if i==int(deee):
break
asd=asd.replace("/","\\")
os.system(f"explorer \"{asd}\"")
break
aadg=Button(y,bg="red",text="Download!",command=lambda:download_images(),activebackground="dark red",activeforeground="grey")
aadg.grid(row=4,column=1)
y.mainloop()
aadg=Button(y,bg="red",text="Download!",command=lambda:download_images(),activebackground="dark red",activeforeground="grey")
aadg.grid(row=4,column=1)
y.mainloop()
但是我们得到的是图片的缩略图而不是图片，因为软件只返回低分辨率的照片，不支持 .gif 图片。
此外，我们无法找到主图像所属的类。 谢谢。
