class FTP
ftp=FTP() #设置变量，类似于初始化
| An FTP client class.
| Methods:
| acct(self, password)
| Send new account name.
|
| close(self) #close连接
| Close the connection without assuming anything about it.
|
| connect(self, host=‘‘, port=0, timeout=-999) #连接的ftp sever和端口，如：ftp.connect(‘192.168.1.188‘,21,30)
|
| cwd(self, dirname) #把当前目录设置为path,设置FTP当前操作的路径
| Change to a directory.
|
| debug = set_debuglevel(self, level) #ftp.set_debuglevel(2) #打开调试级别2，显示详细信息
|
| delete(self, filename) #删除远程文件
| Delete a file.
|
| dir(self, *args) #显示目录下文件信息
| List a directory in long form.
| By default list current directory to stdout.
| Optional last argument is callback function; all
| non-empty arguments before it are concatenated to the
| LIST command. (This *should* only be used for a pathname.)
|
| getline(self) #从服务器输出一行数据
| # Internal: return one line from the server, stripping CRLF.
| # Raise EOFError if the connection is closed
|
| getmultiline(self)
| # Internal: get a response from the server, which may possibly
| # consist of multiple lines. Return a single string with no
| # trailing CRLF. If the response consists of multiple lines,
| # these are separated by ‘\n‘ characters in the string
|
| getresp(self)
| # Internal: get a response from the server.
| # Raise various errors if the response indicates an error
|
| getwelcome(self) #打印出欢迎信息
| Get the welcome message from the server.
| (this is read and squirreled away by connect())
|
| login(self, user=‘‘, passwd=‘‘, acct=‘‘) #登录到FTP服务器，所有的参数都是可选的.
| Login, default anonymous.
|
| makepasv(self)
|
| makeport(self) #创建一个新的套接字，并发送一个端口命令。
| Create a new socket and send a PORT command for it.
|
| mkd(self, dirname) #创建远程目录；建立一个目录，返回其完整路径名
| Make a directory, return its full pathname.
|
| nlst(self, *args) #与dir()类似，但返回一个文件名的列表，而不是显示这些文件名
#返回给定目录下的文件列表（默认情况下）
| Return a list of files in a given directory (default the current).
|
| ntransfercmd(self, cmd, rest=None)
| Initiate a transfer over the data connection.
|
| If the transfer is active, send a port command and the
| transfer command, and accept the connection. If the server is
| passive, send a pasv command, connect to it, and start the
| transfer command. Either way, return the socket for the
| connection and the expected size of the transfer. The
| expected size may be None if it could not be determined.
|
| Optional `rest‘ argument can be a string that is sent as the
| argument to a REST command. This is essentially a server
| marker used to tell the server to skip over any data up to the
| given marker.
|
| putcmd(self, line)
| # Internal: send one command to the server (through putline())
|
| putline(self, line)
| # Internal: send one line to the server, appending CRLF
|
| pwd(self) #当前工作目录
| Return current working directory.
|
| quit(self) #退出ftp
| Quit, and close the connection.
|
| rename(self, fromname, toname) #改文件名，把远程文件fromname 改名为toname
| Rename a file.
|
| retrbinary(self, cmd, callback, blocksize=8192, rest=None)
#与retrlines()类似，只是这个指令处理二进制文件。回调函数
| Retrieve data in binary mode. A new port is created for you.
|
| Args:
| cmd: A RETR command.
| callback: A single parameter callable to be called on each
| block of data read.
| blocksize: The maximum number of bytes to read from the
| socket at one time. [default: 8192]
| rest: Passed to transfercmd(). [default: None]
|
| Returns:
| The response code.
|
| retrlines(self,cmd,callback=None) #
#ftp.retrlines(‘LIST‘)#返回目录内容
#此时可以获得当前ftp目录下的所有文件的信息
| Retrieve data in line mode. A new port is created for you.
|
| Args:
| cmd: A RETR, LIST, NLST, or MLSD command.
| callback: An optional single parameter callable that is called
| for each line with the trailing CRLF stripped.
| [default: print_line()]
|
| Returns:
| The response code.
|
| rmd(self, dirname) #删除远程目录
| Remove a directory.
|
| sanitize(self, s)
| # Internal: "sanitize" a string for printing
|
| sendcmd(self, cmd)
| Send a command and return the response.
|
| sendeprt(self, host, port)
| Send a EPRT command with the current host and the given port number.
|
| sendport(self, host, port)
| Send a PORT command with the current host and the given
| port number.
|
| set_debuglevel(self, level)
#ftp.set_debuglevel(2) #打开调试级别2，显示详细信息
#ftp.set_debuglevel(0) #关闭调试模式
| Set the debugging level.
| The required argument level means:
| 0: no debugging output (default)
| 1: print commands and responses but not body text etc.
| 2: also print raw lines read and sent before stripping CR/LF
|
| set_pasv(self, val)
| Use passive or active mode for data transfers.
| With a false argument, use the normal PORT mode,
| With a true argument, use the PASV command.
|
| size(self, filename) #检索文件大小
| Retrieve the size of a file.
|
| storbinary(self, cmd, fp, blocksize=8192, callback=None, rest=None)
#上传FTP文件
#ftp.storbinaly("STOR filename.txt",file_handel,bufsize) #上传目标文件
#ftp.storbinary(‘STOR ‘+filename, open(path, ‘rb‘)) # 上传FTP文件
#注意storlines的解释
#只是这个指令处理二进制文件。要给定一个文件对象f，上传块大小bs 默认为8Kbs=8192])
| Store a file in binary mode. A new port is created for you.
|
| Args:
| cmd: A STOR command.
| fp: A file-like object with a read(num_bytes) method.
| blocksize: The maximum data size to read from fp and send over
| the connection at once. [default: 8192]

| Store a file in line mode. A new port is created for you.
|
| Args:
| cmd: A STOR command.
| fp: A file-like object with a readline() method.
