##請問我用requests下載幾個G的檔案，結果到差不多一半就不動了是甚麼原因

from tqdm import tqdm
import requests
url = input()


response = requests.get(url, stream=True)
total_size_in_bytes= int(response.headers.get('content-length', 0))
block_size = 10240 #1 Kibibyte
progress_bar = tqdm(total=total_size_in_bytes, unit='iB', unit_scale=True)
with open(response.headers['Content-Disposition'].split('filename=')[1], 'wb') as file:
    for data in response.iter_content(block_size):
        progress_bar.update(len(data))
        file.write(data)
progress_bar.close()
if total_size_in_bytes != 0 and progress_bar.n != total_size_in_bytes:
    print("ERROR, something went wrong")
