1, 下载,必定要看进度
优良的 progress bar
tqdm
装置
sudo python3 -m pip install tqdm
1.1, 加环境变量
#!/usr/bin/python3 from tqdm import tqdm import requests
上一步装置 tqdm 的是 python3 ,
python3 关联到了 tqdm 这个库,不加环境变量,
走默认的 python 2.7,
不是在 python 2.7 上,装置的这个库 tqdm
2 , 下载代码
这个文件,700 M 左右
走文件流,下载的速度,比 Chrome 快多了
走 Chrome 下载,老是失败
#!/usr/bin/python3 from tqdm import tqdm import requests url = 'https://static.realm.io/downloads/swift/realm-swift-10.1.1.zip' # Streaming, so we can iterate over the response. response = requests.get(url, stream=True) total_size_in_bytes = int(response.headers.get('content-length', 0)) block_size = 1024 #1 Kibibyte progress_bar = tqdm(total=total_size_in_bytes, unit='iB', unit_scale=True) path = '/Users/xx/Desktop/Papr-develop/realm-swift-10.1.1.zip' print("总量:") print(total_size_in_bytes) with open(path, '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")
