tkinter下载进度条
利用python爬取网站数据进行下载时,显示下载进度
- # 设置下载进度条
- tk.Label(window, text='下载进度:').place(x=40, y=80)
- canvas = tk.Canvas(window, width=600, height=16, bg="white")
- canvas.place(x=20, y=90)
- # 下载按钮函数
- def usr_download():
- response = session.get(url_str, headers=headers2, cookies=cookies_xxx, verify=False, stream=True) # stream=True表示请求成功后并不会立即开始下载,而是在调用iter_content方法之后才会开始下载
- chunk_size = 40960 # 设置每次下载的块大小
- content_size = int(m4a.headers['content-length']) # 从返回的response的headers中获取文件大小
- # 填充进度条
- fill_line = canvas.create_rectangle(1.5, 1.5, 0, 23, width=0, fill="green")
- raise_data = 600 / (content_size/chunk_size) # 增量大小,600为进度条的长度
- # 将下载的数据写入文件
- with open(title + '.m4a', 'wb') as f:
- n = 0
- for data in response.iter_content(chunk_size=chunk_size): # 在循环读取文件时,刷新进度条
- f.write(data)
- n = n + raise_data
- canvas.coords(fill_line, (0, 0, n, 60))
- window.update()
- # 清空进度条
- def clean_progressbar():
- # 清空进度条
- fill_line = canvas.create_rectangle(1.5, 1.5, 0, 23, width=0, fill="white")
- x = 500 # 未知变量,可更改
- n = 600 / x # 465是矩形填充满的次数
- for t in range(x):
- n = n + 600 / x
- # 以矩形的长度作为变量值更新
- canvas.coords(fill_line, (0, 0, n, 60))
- window.update()
- # 下载按钮
- btn_download = tk.Button(window, text='开始下载', command=usr_download)
- btn_download.place(x=600, y=28)
