QProgreswsBar 如何使用

问题描述

我写了一个简单的解析器。我想用图形来实现它。但是有一个问题：我不知道该怎么做。

我会说下面的，我找到了进度条的代码。你能帮忙把程序中的代码和进度条码连接起来，让它们正常工作吗？好吧，或者告诉我往哪个方向移动。 解析器代码：

import requests
from bs4 import BeautifulSoup
import csv
import time


CSV = 'item.csv'
HOST = 'https://www.goodfon.ru'
URL = 'https://www.goodfon.ru/'
HEADERS = { 
    'accept': 'text/html,application/xhtml+xml,application/xml;q=0.9,image/avif,image/webp,image/apng,*/*;q=0.8,'
              'application/signed-exchange;v=b3;q=0.9','user-agent': 'Mozilla/5.0 (Windows NT 10.0; WOW64) AppleWebKit/537.36 (KHTML,like Gecko) Chrome/88.0.4324.152 '
                  'YaBrowser/21.2.3.106 Yowser/2.5 Safari/537.36 '
}


def get_html(url,params=''): 
    r = requests.get(url,headers=HEADERS,params=params)
    return r


def get_content(html): 
    soup = BeautifulSoup(html,'html.parser')
    items = soup.find_all('div',class_='wallpapers__item')
    img = []

    for item in items:
        img.append(
            {
                'url': item.find('div',class_='wallpapers__item__wall').find('a').get('href'),'size': item.find('div',class_='wallpapers__item__size').find('small').text,'permission': item.find('div',class_='wallpapers__item__size').find('span').text,}
        )
    return img

def save_doc(items,path):
    with open(path,'w',encoding='utf8',newline='') as file:
        writer = csv.writer(file,delimiter=',')
        writer.writerow(['Ссылка','Разрешение','Формат'])
        for item in items:
            writer.writerow([item['url'],item['size'],item['permission']])

def parser(): 
    time_begin = time.time()
    PATH = int(input('Укажите количество страниц для парсинга: ').strip())
    html = get_html(URL)
    if html.status_code == 200:
        img = []
        for page in range(1,PATH + 1):
            print(f'Парсим страницу №  {page}')
            html = get_html(URL,params='index-' + str(page) + '.html')
            img.extend(get_content(html.text))
            save_doc(img,CSV)
        print(img)
    else:
        print("Error!")
    time_end = time.time()
    time_result = round(time_end - time_begin,3)
    time_sec = round(time_result / 60,3)
    print(f'На парсинг {PATH} страниц было затрачено {time_result} секунд.({time_sec} минут/ы)')
