python - python imagedownloader，不能作为类在其他文件中工作

Question

这是我的第一个程序，它是一个“imagedownloader”，用户可以输入宽度和高度。当我在单个文件中运行我的代码而不创建类时，它可以工作。但是在尝试将其作为一个类并将其导入到主文件之后，它不再起作用了，但是没有错误。这就是我导入模块并创建对象的方式。

主文件：

from DownLoader import *

d = DownLoader("https://imga.biz/", 40, 40)

d.down()

下载模块：

from bs4 import BeautifulSoup
import requests
from PIL import Image
from io import BytesIO



class DownLoader:
    def __init__(self, url_, xx, yz):
        self.url = url_
        self.x = xx
        self.y = yz
        self.page = requests.get(self.url)
        self.soup = BeautifulSoup(self.page.text, "html.parser")
        self.images = self.soup.find_all("img")
        self.images_src_array = []
        self.src_old = ""
        for i in self.images:
            if i['src'][0:4] == "http": #check if its a https site
                if i['src'] == self.src_old: #whether is the same image as last
                    continue
                else:
                    self.images_src_array.append(i['src'])
                    self.src_old = i['src']

    def down(self):
        name = ""
        index = 0
        for img in self.images_src_array:
            if self.check_image_size(img)[0] >= self.x and self.check_image_size(img)[1] >= self.y:
                img_data = requests.get(img).content
                with open(name + str(index) + ".jpg", 'wb') as handler:
                    handler.write(img_data)
                    print(str(index) + " : " + img)
                    index += 1


    def check_image_size(self, url):
        try:
            img_data = requests.get(url).content
            img = Image.open(BytesIO(img_data))
            return img.size
        except Exception:
            return (0, 0)

没有类或导入的下载器，我试图转换为类：

from bs4 import BeautifulSoup
import requests
from PIL import Image
from io import BytesIO

url = input("Enter Url: ")
x = int(input("insert width: "))
y = int(input("insert height: "))
page = requests.get(url)
soup = BeautifulSoup(page.text, "html.parser")
images = soup.find_all("img")
images_src_array = []
src_old = ""

for src in images:
    if src['src'][0:4] == "http": #check if its a https site
        if src['src'] == src_old: #whether is the same image as last
            continue
        else:
            images_src_array.append(src['src'])
            src_old = src['src']


def download(images_src, width, height):
    name = ""
    index = 0
    for img in images_src:
        if check_image_size(img)[0] >= width and check_image_size(img)[1] >= height: #checks size and also if its image
            img_data = requests.get(img).content
            with open(name+str(index)+".jpg", 'wb') as handler:
                handler.write(img_data)
                print(str(index) + " : " + img)
                index += 1


def check_image_size(url_link):
    try:
        data = requests.get(url_link).content
        img = Image.open(BytesIO(data))
        return img.size
    except Exception:
        return (0,0) #return for height and width


download(images_src_array, x, y)

print("\nfinish")
page.close()
