java代码怎么实现在linux系统上上传文件到windows服务器上
一般linux下传输文件到windows,直接用发ftp就行 ,具体操作1、在windows下,点开始按钮,选:运行,进入DOS
2、在dos下面输入ftp 192.168.1.1(liunx服务器IP地址)然后提示输入,用户名,密码
进入linux服务器的FTP界面,此时输入binary(binary是安全传输方式)
3、此时输入cd /usr(用cd命令切换到相应传输目录)
4输入 get find (要传输的文件)
搞定
仅20行代码,实现文件自动化上传至sftp
最近接到一个产品需求是给指定的 sftp 服务器的指定目录定时推送文件数据。
因为项目组已有现成的组件可以轻松实现 sftp 服务器文件的快速上传,本来是一件很容易的事情,但是问题出现在这个指定的 sftp 服务器所指定的密码带有系统关键字和一些特殊字符,导致现在的组件在解析过程中会失败。 -代码实现文件传输
因此重新开发了下面的这套脚本来满足这个特殊的需求。
Python代码
sftp配置文件代码
(1). yaml 模块
导入 yaml 模块前可以使用以下命令进行模块的安装
yaml 模块在这里的作用是读取 sftp 配置文件代码,将指定key: test_file_upload 下的 key:value 的值转换为字典。
例如:load_config_from_param_conf 函数中的返回值就是使用 yaml 读取到 sftp 配置文件代码后,返回 key: test_file_upload 下配置选项值。 -代码实现文件传输
格式如下:
最后将返回值传给 upload 函数作为参数。
(2). OptionParser 模块
按照 yaml 模块的安装方法,先安装 optparse 模块后,然后在文件中从optparse 中导入 OptionParser 模块
在这里我使用了 OptionParser 这个类实例化了一个对象:opt_parser,通过对象来调用 add_option 方法添加了2个参数,分别是:node, local_file
1). 形参:--node,实参:node
所代表的业务含义是:指定要上传的 sftp 的节点,具体参数值对应 sftp配置文件代码中的 test_file_upload
2). 形参:--local_file,实参:local_file
所代表的业务含义是:指定本地需要被上传到 sftp 服务器的具体文件路径
3). 调用命令
4). add_option()方法
参数:action的枚举
store: 参数列表中带有--node, 那么就会将下一个元素即:test_file_upload 作为其 dest 实参 node 的值; 如果没有--node,那么对应的node的值就为 None; -代码实现文件传输
store_true: 参数列表中有--local_file, 那么其 dest 实参 local_file 的值就为 True; 否者就为 default 定义的默认值,这里没有给定 default 的默认值; -代码实现文件传输
store_false: 参数列表中有--local_file, 那么其 dest 实参 local_file 的值就为 False; 否者就为 default 定义的默认值,这里没有给定 default 的默认值; -代码实现文件传输
参数:type
type是指定传入参数的类型,这里的参数类型为 string 类型。
参数:dest
dest是参数传入后由哪个变量来存储的,后面代码对该参数的引用也是使用这里定义的变量名来引用的。
参数:default
default 是与 action 的值结合使用的。
参数:help
help相当于帮助说明文档,用于描述这个参数的含义。

用java多线程实现服务器与客户端之间的文件传输的代码!!!急!!!!
程序分Server和Client
服务器端打开侦听的端口,一有客户端连接就创建两个新的线程来负责这个连接
一个负责客户端发送的信息(ClientMsgCollectThread 类),
另一个负责通过该Socket发送数据(ServerMsgSendThread )
