tkinter下載進(jìn)度條

利用python爬取網(wǎng)站數(shù)據(jù)進(jìn)行下載時(shí)，顯示下載進(jìn)度

# 設(shè)置下載進(jìn)度條tk.Label(window, text=’下載進(jìn)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(shù)def usr_download(): response = session.get(url_str, headers=headers2, cookies=cookies_xxx, verify=False, stream=True) # stream=True表示請(qǐng)求成功后并不會(huì)立即開(kāi)始下載，而是在調(diào)用iter_content方法之后才會(huì)開(kāi)始下載 chunk_size = 40960 # 設(shè)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(jìn)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(jìn)度條的長(zhǎng)度 # 將下載的數(shù)據(jù)寫(xiě)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(huán)讀取文件時(shí)，刷新進(jìn)度條f.write(data) n = n + raise_data canvas.coords(fill_line, (0, 0, n, 60)) window.update() # 清空進(jìn)度條def clean_progressbar(): # 清空進(jìn)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(mǎn)的次數(shù) for t in range(x): n = n + 600 / x # 以矩形的長(zhǎng)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(kāi)始下載’, command=usr_download)btn_download.place(x=600, y=28)
