tkinter下載進度條
利用python爬取網站數據進行下載時,顯示下載進度
- # 設置下載進度條
- tk.Label(window, text='下載進度:').place(x=40, y=80)
- canvas = tk.Canvas(window, width=600, height=16, bg="white")
- canvas.place(x=20, y=90)
- # 下載按鈕函數
- def usr_download():
- response = session.get(url_str, headers=headers2, cookies=cookies_xxx, verify=False, stream=True) # stream=True表示請求成功后并不會立即開始下載,而是在調用iter_content方法之后才會開始下載
- chunk_size = 40960 # 設置每次下載的塊大小
- content_size = int(m4a.headers['content-length']) # 從返回的response的headers中獲取文件大小
- # 填充進度條
- 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為進度條的長度
- # 將下載的數據寫入文件
- with open(title + '.m4a', 'wb') as f:
- n = 0
- for data in response.iter_content(chunk_size=chunk_size): # 在循環讀取文件時,刷新進度條
- f.write(data)
- n = n + raise_data
- canvas.coords(fill_line, (0, 0, n, 60))
- window.update()
- # 清空進度條
- def clean_progressbar():
- # 清空進度條
- fill_line = canvas.create_rectangle(1.5, 1.5, 0, 23, width=0, fill="white")
- x = 500 # 未知變量,可更改
- n = 600 / x # 465是矩形填充滿的次數
- for t in range(x):
- n = n + 600 / x
- # 以矩形的長度作為變量值更新
- canvas.coords(fill_line, (0, 0, n, 60))
- window.update()
- # 下載按鈕
- btn_download = tk.Button(window, text='開始下載', command=usr_download)
- btn_download.place(x=600, y=28)
