一、代码
1.server.py
import os
from http.server import SimpleHTTPRequestHandler, HTTPServer
import cgi # 自定义请求处理类
class MyRequestHandler(SimpleHTTPRequestHandler):# 处理GET请求def do_GET(self):if self.path == '/':# 响应200状态码self.send_response(200)# 设置响应头为text/htmlself.send_header('Content-type', 'text/html')self.end_headers()# 读取并发送upload.html文件内容with open('upload.html', 'rb') as file:self.wfile.write(file.read())else:# 调用父类方法处理其他路径的GET请求super().do_GET()# 处理POST请求def do_POST(self):if self.path == '/upload':# 解析表单数据form = cgi.FieldStorage(fp=self.rfile,headers=self.headers,environ={'REQUEST_METHOD': 'POST','CONTENT_TYPE': self.headers['Content-Type']})if 'file' in form:file_item = form['file']if file_item.filename:# 构建文件保存路径file_path = os.path.join('uploads', file_item.filename)# 将上传的文件保存到指定路径with open(file_path, 'wb') as f:f.write(file_item.file.read())# 响应200状态码self.send_response(200)# 设置响应头为text/htmlself.send_header('Content-type', 'text/html')self.end_headers()# 发送上传成功的消息self.wfile.write('文件上传成功'.encode('utf-8'))else:# 如果没有选择文件，返回400错误self.send_error(400, '未选择文件')else:# 如果缺少文件字段，返回400错误self.send_error(400, '缺少文件字段')else:# 如果路径不存在，返回404错误self.send_error(404, '未找到')# 主程序入口
if __name__ == '__main__':# 检查并创建上传目录if not os.path.exists('uploads'):os.makedirs('uploads')# 定义服务器端口号PORT = 8000 # 创建HTTP服务器with HTTPServer(('', PORT), MyRequestHandler) as httpd:print(f'服务器运行在端口 {PORT}')# 启动服务器，持续监听请求httpd.serve_forever()
2.upload.html
<!DOCTYPE html>
<html lang="zh-CN">
<head><meta charset="UTF-8"><meta name="viewport" content="width=device-width, initial-scale=1.0"><title>文件上传</title>
</head>
<body><h1>上传文件</h1><form action="/upload" method="post" enctype="multipart/form-data"><label for="file">选择要上传的文件：</label><input type="file" id="file" name="file" required><br><br><button type="submit">上传</button></form>
</body>
</html>
3.upload.html 可显示进度条
<!DOCTYPE html>
<html lang="zh-CN">
<head><meta charset="UTF-8"><meta name="viewport" content="width=device-width, initial-scale=1.0"><title>文件上传</title><style>#progressBarContainer {width: 100%;background-color: #f3f3f3;margin-top: 10px;}#progressBar {width: 0%;height: 20px;background-color: #4caf50;text-align: center;line-height: 20px;color: white;}</style>
</head>
<body><h1>上传文件</h1><form id="uploadForm" enctype="multipart/form-data"><label for="file">选择要上传的文件：</label><input type="file" id="file" name="file" required><br><br><div id="progressBarContainer"><div id="progressBar">0%</div></div><button type="button" onclick="uploadFile()">上传</button></form><script>function uploadFile() {var form = document.getElementById('uploadForm');var formData = new FormData(form);var xhr = new XMLHttpRequest();xhr.open('POST', '/upload', true);// 更新进度条xhr.upload.onprogress = function(event) {if (event.lengthComputable) {var percentComplete = (event.loaded / event.total) * 100;var progressBar = document.getElementById('progressBar');var progressText = document.createTextNode(Math.round(percentComplete) + '%');progressBar.style.width = percentComplete + '%';progressBar.innerHTML = ''; // 清空旧文本progressBar.appendChild(progressText); // 添加新文本}};xhr.onload = function() {if (xhr.status === 200) {alert('文件上传成功！');} else {alert('文件上传失败！');}};xhr.onerror = function() {alert('上传过程中发生错误！');};xhr.send(formData);}</script>
</body>
</html>
4. serverOpen.bat
@echo off
REM 关闭命令回显，使输出更干净
python server.py
REM 启动命令提示符
start cmd
二、测试
双击serverOpen.bat运行httpServer
uploads文件夹下出现
