获取文件大小，文件上传速率等代码

获取文件大小的代码：

import os

def get_file_size(file_path):
    """获取文件大小，单位为字节"""
    return os.path.getsize(file_path)

获取上传速率的代码：

import time

def calculate_upload_speed(file_size, start_time, end_time):
    """计算上传速率，单位为字节/秒"""
    time_elapsed = end_time - start_time
    return file_size / time_elapsed

上传文件的代码：

import requests

def upload_file(file_path, url):
    """上传文件"""
    with open(file_path, 'rb') as f:
        file_data = f.read()
    start_time = time.time()
    response = requests.post(url, data=file_data)
    end_time = time.time()
    if response.status_code == 200:
        file_size = get_file_size(file_path)
        upload_speed = calculate_upload_speed(file_size, start_time, end_time)
        print(f"上传成功！文件大小为{file_size}字节，上传速率为{upload_speed}字节/秒")
    else:
        print("上传失败！")
