一、定义
- flask 文件下载
- python 接收tar 文件
二、实现
-
flask 文件下载
from flask import Flask, send_file, request
import os
from gevent.pywsgi import WSGIServer
import logginglogging.basicConfig(level=logging.INFO, format="%(asctime)s %(filename)s [line:%(lineno)d] %(levelname)s %(message)s")
app = Flask(name)@app.route('/download', methods=["GET"])
def download_tar():
# 设置tar文件的路径
tar_file_path = request.args.get("filename")
tar_file_path = os.path.join("/home/jiayafei_linux/downloads_files", tar_file_path)
logging.info(str(tar_file_path))
# 检查文件是否存在
if not os.path.isfile(tar_file_path):
return "File not found", 404
# 设置文件名,这将作为下载时的默认文件名
filename = os.path.basename(tar_file_path)
logging.info(str(filename))
# 使用send_file发送文件
return send_file(tar_file_path, as_attachment=True, download_name=filename)if name == 'main':
print("start")
http_server = WSGIServer(('0.0.0.0', int(8010)), app)
http_server.serve_forever() -
python 接收tar 文件
#接收tar 文件,并保存到本地 baike_10000k_0.tar
def download_file_with_progress(self, url, save_path):
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)with open(save_path, 'wb') as file: for data in response.iter_content(block_size): progress_bar.update(len(data)) file.write(data) progress_bar.close()
