开发原因
MobaXterm作为一个全能型终端神器，功能十分强大，我经常使用其中隧道功能，使用内部无法直接服务器，查询数据，一般来说，一个本地端口对于一个隧道，但是MobaXterm，免费版本最多只能建立三个隧道，比如，我需要一次查询统计，就会用到四个隧道的操作，就非常不方便，需要调整一个隧道，于是，便用python写了多隧道的客户端
效果图界面使用tkinter实现，左边是输入隧道的信息，右边为历史列表，
源码分析 构建隧道 def operate_sshtunnel(tunnel_info): try: tunnel = SSHTunnelForwarder( (tunnel_info.ssh_ip, int(tunnel_info.ssh_port)), ssh_username=tunnel_info.ssh_username, ssh_password=tunnel_info.ssh_password, remote_bind_address=(tunnel_info.remote_ip, int(tunnel_info.remote_port)), local_bind_address=('127.0.0.1', int(tunnel_info.localhost_port)) ) return tunnel except Exception as e: print(e.args[0]) messagebox.showinfo(title='连接异常', message=e.args[0]) return这段代码就是整个功能的核心代码，使用SSHTunnelForwarder模块的sshtunnel
构建隧道，由于我只需要一个本地端口访问远程远程服务器的功能，默认本地端口固定为127.0.0.1
初始化加载 def read_json(): if os.path.exists('tunnel_data.json'): with open('tunnel_data.json', 'r', encoding='utf-8') as load_f: data = load_f.read() if len(data) > 0: json_str = cryptocode.decrypt(data, "EjdeB55cvQMN2WHf") return json.loads(json_str) else: return def load_config(): load_arr = read_json() if load_arr is not None: for tunnel_info_json in load_arr: tunnel_info = tunnel_info_class() tunnel_info.localhost_port = tunnel_info_json['localhost_port'] tunnel_info.ssh_ip = tunnel_info_json['ssh_ip'] tunnel_info.ssh_port = tunnel_info_json['ssh_port'] tunnel_info.ssh_username = tunnel_info_json['ssh_username'] tunnel_info.ssh_password = cryptocode.decrypt(tunnel_info_json['ssh_password'], "F1jgEg1arVyxmUqC") tunnel_info.remote_ip = tunnel_info_json['remote_ip'] tunnel_info.remote_port = tunnel_info_json['remote_port'] tunnel_info.tunnel_name = tunnel_info_json['tunnel_name'] tree_id = insert_tree_view(tunnel_info, "未启动") tunnel_infos.update({tree_id: tunnel_info})read_json是读取历史记录，其中使用 cryptocode模版对明文的json进行加密，并且对ssh_password进行再加密
开始服务 def start_tunnel(): iid = treeview.selection() if len(iid) > 0: if iid not in tunnel_infos_start.keys(): tunnel_info = tunnel_infos[iid[0]] tunnel = ssl_tunnel.operate_sshtunnel(tunnel_info) if tunnel is not None: try: tunnel.start() tunnel_infos_start.update({iid[0]: tunnel}) update_tree_view(iid[0], tunnel_info, "启动") pass except Exception as e: messagebox.showinfo(title='连接异常', message=e.args[0]) else: messagebox.showinfo(title='选择异常', message="未选择列表")tunnel_infos为报存的隧道信息字典，tunnel_infos_start为报存的已经启动的隧道字典，先获取点击到的行的ID，然后查询是否在已启动的字典中，如果不存在则，启动隧道，同时更新到tunnel_infos_start中
停止服务 def stop_tunnel(): iid = treeview.selection() if len(iid) > 0: if iid[0] in tunnel_infos_start.keys(): tunnel_info = tunnel_infos[iid[0]] tunnel = tunnel_infos_start[iid[0]] if tunnel is not None: try: tunnel.stop() tunnel_infos_start.pop(iid[0]) update_tree_view(iid[0], tunnel_info, "未启动") pass except Exception as e: messagebox.showinfo(title='连接异常', message=e.args[0]) else: messagebox.showinfo(title='选择异常', message="未选择列表")这段代码操作和启动相反，则是从停止掉服务，同时从tunnel_infos_start中移除掉该隧道
移除服务 def remove_tunnel(): iid = treeview.selection() if len(iid) > 0: if iid[0] in tunnel_infos_start.keys(): stop_tunnel() ## 从列表删除 treeview.delete(iid) tunnel_infos.pop(iid[0]) write_json() else: messagebox.showinfo(title='选择异常', message="未选择列表")移除服务的时候，会判断ID在tunnel_infos_start是否存在，存在则表明当前删除的隧道还在启动中，则停止这个服务，同时从tunnel_infos移除这配置，更新tunnel_data.json文件
不足之处虽然这个简单的工具可以满足超过多个隧道的使用，但是每次报存的时候，都要更新tunnel_data.json文件，如果隧道比较多，加载比较费时间；同时由于设计界面的时候，考虑比较简单，并不支持修改的功能，只能删除错误的记录，然后重新报存
