5.25 python 功能（对石家庄铁道大学网站稳定性的检测）

我今天完善了一下我的python大作业中对石家庄铁道大学网站运行时间，同时承载多少用户同时点击之后还能稳定运行，以及对用户访问时响应速度的一个监测。

代码如下：

import requests
import time
import tkinter as tk


class Application(tk.Frame):
    def __init__(self, master=None):
        super().__init__(master)
        self.master = master
        self.master.title("服务器性能测试")
        self.create_widgets()

    def create_widgets(self):
        self.url_label = tk.Label(self.master, text="URL：")
        self.url_label.grid(row=0, column=0)

        self.url_entry = tk.Entry(self.master)
        self.url_entry.grid(row=0, column=1)

        self.requests_label = tk.Label(self.master, text="请求数量：")
        self.requests_label.grid(row=1, column=0)

        self.requests_entry = tk.Entry(self.master)
        self.requests_entry.grid(row=1, column=1)

        self.timeout_label = tk.Label(self.master, text="超时时间：")
        self.timeout_label.grid(row=2, column=0)

        self.timeout_entry = tk.Entry(self.master)
        self.timeout_entry.grid(row=2, column=1)

        self.start_button = tk.Button(self.master, text="开始测试", command=self.start_test)
        self.start_button.grid(row=3, column=1)

        self.result_label = tk.Label(self.master, text="")
        self.result_label.grid(row=4, column=0, columnspan=2, pady=10)

    def start_test(self):
        url = self.url_entry.get()
        num_requests = int(self.requests_entry.get())
        timeout = int(self.timeout_entry.get())
        self.result_label.config(text=f"正在测试，请稍候...")
        self.result_label.update()

        # 进行服务器性能测试
        total_response_time = 0
        total_requests = 0
        timeouts = 0
        max_response_time = 0

        for i in range(num_requests):
            # 模拟请求，并记录响应时间和状态码
            start_time_i = time.time()
            try:
                res = requests.get(url, timeout=timeout)
                status_code = res.status_code
                elapsed_time = time.time() - start_time_i
                total_response_time += elapsed_time
                total_requests += 1
                max_response_time = max(max_response_time, elapsed_time)
            except requests.exceptions.Timeout:
                timeouts += 1

        # 打印测试结果
        if total_requests == 0:
            self.result_label.config(text=f"所有请求都未响应成功")
        else:
            success_rate = (total_requests / num_requests) * 100
            average_response_time = total_response_time / total_requests
            self.result_label.config(text=f"共发送 {num_requests} 个请求，成功率为 {success_rate:.2f}%，\n"
                                           f"平均响应时间为 {average_response_time:.3f} 秒，最大响应时间为 {max_response_time:.3f} 秒。\n"
                                           f"超时次数为 {timeouts}")

        self.result_label.update()


if __name__ == "__main__":
    root = tk.Tk()
    app = Application(master=root)
    app.mainloop()
