使用response.setHeader("Content-Disposition","attachment;filename="+fName)下载文件,中文文件名无法显示的问题

response.setContentType("application/x-download");
response.setHeader("Content-Disposition","attachment;filename="+file_name);
OutputStream outputStream = response.getOutputStream();
InputStream inputStream = new FileInputStream(file_uri());
byte[] buffer = new byte[1024];
int i = -1;
while ((i = inputStream.read(buffer)) != -1) {
    outputStream.write(buffer, 0, i);
}
outputStream.flush();
outputStream.close();
inputStream.close();

假设file_nam的内容是:“工程文档.docx”

那么下载的结果就是一个名为“docx”的文件(文件名+后缀名),显然,文件名中的中文字符丢失了

上网查了资料,解决办法如下(我也感觉很不可思议,但的确管用了)

 

response.setContentType("application/x-download");
file_name = new String(file_name.getBytes(), "ISO-8859-1");
response.setHeader("Content-Disposition","attachment;filename="+file_name);
// 其他代码略

 

那么根据我的提供的代码帮我添加一下,在HTTP模式下登录成功,对该用户名添加cookie和httponly from utils import USER_FILE, UPLOAD_DIR, DOWNLOAD_DIR, load_users, save_user, check_user, check_user_md5 from bottle import Bottle, static_file, redirect, request, run, template, BaseRequest, response from bottle_auth import AuthPlugin import hashlib import os import ctypes import tarfile import tempfile from routes_en import setup_routes_en, cleanup_tar_files import threading import time USER_FILE = '/mnt/usrfs/webTest/user_auth.txt' UPLOAD_DIR = '/mnt/usrfs/upload' DOWNLOAD_DIR = '/mnt/usrfs/' BaseRequest.MEMFILE_MAX = 1024 * 1024 * 15 # 15MB # 5. 自定义 AuthPlugin,支持md5密码 class MD5AuthPlugin(AuthPlugin): def __init__(self, users): super().__init__(users) def check_auth(self, username, password): # password是明文,转md5后比对 pwd_md5 = hashlib.md5(password.encode()).hexdigest() return check_user_md5(username, pwd_md5) def require(self, f): def check_auth(*args, **kwargs): username = request.auth[0] if request.auth else None password = request.auth[1] if request.auth else None if not username or not password: response.headers['WWW-Authenticate'] = 'Basic realm=\"Login Required\"' response.status = 401 return "Authentication required" if not self.check_auth(username, password): response.headers['WWW-Authenticate'] = 'Basic realm=\"Login Required\"' response.status = 401 return "Authentication failed" return f(*args, **kwargs) return check_auth # 6. 创建 Bottle 应用 app = Bottle() users = load_users() auth = MD5AuthPlugin(users) app.install(auth) setup_routes_en(app,auth) # 启动清理线程 if __name__ == '__main__': # 如果没有用户文件,自动创建一个默认用户 if not os.path.exists(USER_FILE): save_user('root', 'root') # 使用最简单的配置 t = threading.Thread(target=cleanup_tar_files, daemon=True) t.start() app.run(host='0.0.0.0', port=80, debug=False, reloader=False)以上是main;from utils import USER_FILE, UPLOAD_DIR, DOWNLOAD_DIR, check_user from bottle import static_file, redirect, request, template, response from bottle import template from page_generators_en import get_basic_info_html_en, get_dev_status_html_en import tarfile import os import time from vtysh_cmd_send import VtyshCommandExecutor USER_FILE = '/mnt/usrfs/webTest/user_auth.txt' UPLOAD_DIR = '/mnt/usrfs/upload' DOWNLOAD_DIR = '/mnt/usrfs/' def setup_routes_en(app, auth): @app.route('/www/baseMsg_en.asp') def basic_info_www_en(): html = get_basic_info_html_en() return template('basic_info_en', basic_info_html_en=html) @app.route('/www/devStatus_en.asp') def dev_status_www_en(): html = get_dev_status_html_en() return template('dev_status_en', dev_status_html_en=html) @app.route('/www/ipaddr_en.asp') def ip_config_page(): return template('ip_address_en') @app.route('/api/execute_ip_config', method='POST') def execute_ip_config(): try: # 获取前端发送的配置 config = request.json # 验证配置 if not config or 'network' not in config: return {'success': False, 'error': 'Invalid configuration'} # 使用VtyshCommandExecutor执行配置 from vtysh_cmd_send import VtyshCommandExecutor executor = VtyshCommandExecutor("../bin/vtysh") result = executor.execute_config(config) return result except Exception as e: return {'success': False, 'error': str(e)} # def file_root_en(app): @app.route('/') def index(): return redirect('/www/index1/index_en.html') @app.route('/download_file/<path:path>') def download_file(path): print(f"DEBUG: 下载请求路径: {path}") # 调试信息 abs_file = os.path.abspath(os.path.join(DOWNLOAD_DIR, path)) print(f"DEBUG: 绝对文件路径: {abs_file}") # 调试信息 # 检查DOWNLOAD_DIR是否存在 if not os.path.exists(DOWNLOAD_DIR): print(f"DEBUG: DOWNLOAD_DIR不存在") # 调试信息 return "DOWNLOAD_DIR不存在" if not abs_file.startswith(os.path.abspath(DOWNLOAD_DIR)): print(f"DEBUG: 路径安全检查失败") # 调试信息 return "非法路径" # 检查文件或目录是否存在 if not os.path.exists(abs_file): print(f"DEBUG: 文件/目录不存在: {abs_file}") # 调试信息 return f"文件/目录不存在: {abs_file}" # 如果是目录,创建tar文件 if os.path.isdir(abs_file): print(f"DEBUG: 开始打包目录: {abs_file}")# 调试信息 try: # 在DOWNLOAD_DIR中创建tar文件,而不是临时目录 tar_filename = os.path.basename(abs_file) + '.tar' tar_path = os.path.join(DOWNLOAD_DIR, tar_filename) print(f"DEBUG: tar文件路径: {tar_path}") # 调试信息 # 创建tar文件 with tarfile.open(tar_path, 'w') as tar: tar.add(abs_file, arcname=os.path.basename(abs_file)) # 检查tar文件是否创建成功 if os.path.exists(tar_path): file_size = os.path.getsize(tar_path) print(f"DEBUG: tar文件创建成功,大小: {file_size} 字节") # 调试信息 else: print(f"DEBUG: tar文件创建失败") # 调试信息 return "tar文件创建失败" print(f"DEBUG: 目录打包完成: {tar_path}") # 调试信息 print(f"DEBUG: 下载文件名: {tar_filename}") # 调试信息 # 使用static_file返回tar文件 # 设置响应头 response.set_header('Content-Type', 'application/x-tar') response.set_header('Content-Disposition', f'attachment;
