帮我写一份 python 的压力测试用例

在Python中，压力测试通常用来评估系统在高负载下的性能。以下是一个简单的例子，假设我们正在测试一个HTTP客户端，该客户端从服务器接收数据。我们将创建一个模拟并发请求的场景来进行压力测试：

import requests
from threading import Thread
import time
import random

# 设定目标URL和最大并发数
url = "http://your-server.com/api"
max_threads = 10
requests_per_thread = 100

def load_test():
    for _ in range(requests_per_thread):
        try:
            response = requests.get(url, timeout=1) # 设置超时防止阻塞
            if not response.ok:
                print(f"Request failed with status code {response.status_code}")
        except Exception as e:
            print(f"Error during request: {str(e)}")

def stress_test(max_threads):
    threads = []
    for _ in range(max_threads):
        thread = Thread(target=load_test)
        threads.append(thread)
        thread.start()

    # 等待所有线程执行完毕
    for thread in threads:
        thread.join()

# 运行压力测试
stress_test(max_threads)

在这个例子中，`load_test`函数模拟了并发的GET请求，而`stress_test`则启动指定数量的线程同时运行。你可以调整`max_threads`和`requests_per_thread`参数以改变压力程度。
