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 Kibibyteprogress_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()
