Python如何使用Requests下载文件并且显示进度条

import requests

total = 10485
url = f'https://speed.cloudflare.com/__down?during=download&bytes={total}'
# 上面的 URL 是 cloudflare 的测试链接，可以传入想要下载的长度
res = requests.get(url)

with open('test.file', 'wb') as file:
    file.write(res.content)
print('下载完成')

import json
import requests

r = requests.get('https://httpbin.org/stream/20', stream=True)

for line in r.iter_lines():

    # filter out keep-alive new lines
    if line:
        decoded_line = line.decode('utf-8')
        print(json.loads(decoded_line))

poetry add tqdm
# 或者
pip install tqdm

import requests
from tqdm import tqdm

total = 104857600  # 100M
url = f'https://speed.cloudflare.com/__down?during=download&bytes={total}'
res = requests.get(url, stream=True)
# 上面的 URL 是 cloudflare 的测试链接，可以传入想要下载的长度，如果是正常的下载文件，需要通过下面的代码来获取总长度
# file_size = int(response.headers.get("Content - Length", 0))
print(total)
with open('test.file', 'wb') as file, tqdm(
        desc='test.file',
        total=total,
        unit='iB',
        unit_scale=True,
        unit_divisor=1024,
) as bar:
    for data in res.iter_content(chunk_size=1024):
        size = file.write(data)
        bar.update(size)
