Georg Brandl | 116aa62 | 2007-08-15 14:28:22 +0000 | [diff] [blame] | 16 | This module defines the class :class:`FTP` and a few related items. The |
| 17 | :class:`FTP` class implements the client side of the FTP protocol. You can use |
| 18 | this to write Python programs that perform a variety of automated FTP jobs, such |
Senthil Kumaran | aca8fd7 | 2008-06-23 04:41:59 +0000 | [diff] [blame] | 19 | as mirroring other ftp servers. It is also used by the module |
| 20 | :mod:`urllib.request` to handle URLs that use FTP. For more information on FTP |
| 21 | (File Transfer Protocol), see Internet :rfc:`959`. |

Alexandre Vassalotti | 5f8ced2 | 2008-05-16 00:03:33 +0000 | [diff] [blame] | 47 | method call ``connect(host)`` is made. When *user* is given, additionally |
| 48 | the method call ``login(user, passwd, acct)`` is made (where *passwd* and |
| 49 | *acct* default to the empty string when not given). The optional *timeout* |
| 50 | parameter specifies a timeout in seconds for blocking operations like the |

Giampaolo Rodolà | 396ff06 | 2011-02-28 19:19:51 +0000 | [diff] [blame] | 52 | will be used). *source_address* is a 2-tuple ``(host, port)`` for the socket |
| 53 | to bind to as its source address before connecting. |

Antoine Pitrou | c5e075f | 2014-03-22 18:19:11 +0100 | [diff] [blame] | 83 | explicitly ask for it by calling the :meth:`prot_p` method. *context* |
| 84 | is a :class:`ssl.SSLContext` object which allows bundling SSL configuration |
| 85 | options, certificates and private keys into a single (potentially |
| 86 | long-lived) structure. Please read :ref:`ssl-security` for best practices. |
| 87 | |
| 88 | *keyfile* and *certfile* are a legacy alternative to *context* -- they |

| 161 | FTP Objects |
| 162 | ----------- |
| 163 | |
| 164 | Several methods are available in two flavors: one for handling text files and |
| 165 | another for binary files. These are named for the command which is used |
| 166 | followed by ``lines`` for the text version or ``binary`` for the binary version. |
| 167 | |
| 168 | :class:`FTP` instances have the following methods: |
| 169 | |
| 170 | |
| 171 | .. method:: FTP.set_debuglevel(level) |
| 172 | |
| 173 | Set the instance's debugging level. This controls the amount of debugging |
| 174 | output printed. The default, ``0``, produces no debugging output. A value of |
| 175 | ``1`` produces a moderate amount of debugging output, generally a single line |
| 176 | per request. A value of ``2`` or higher produces the maximum amount of |
| 177 | debugging output, logging each line sent and received on the control connection. |

Georg Brandl | 116aa62 | 2007-08-15 14:28:22 +0000 | [diff] [blame] | 181 | |
| 182 | Connect to the given host and port. The default port number is ``21``, as |
| 183 | specified by the FTP protocol specification. It is rarely needed to specify a |
| 184 | different port number. This function should be called only once for each |
| 185 | instance; it should not be called at all if a host was given when the instance |
| 186 | was created. All other methods can only be used after a connection has been |
| 187 | made. |
Georg Brandl | 116aa62 | 2007-08-15 14:28:22 +0000 | [diff] [blame] | 188 | The optional *timeout* parameter specifies a timeout in seconds for the |
Georg Brandl | f78e02b | 2008-06-10 17:40:04 +0000 | [diff] [blame] | 189 | connection attempt. If no *timeout* is passed, the global default timeout |
| 190 | setting will be used. |
Giampaolo Rodolà | 396ff06 | 2011-02-28 19:19:51 +0000 | [diff] [blame] | 191 | *source_address* is a 2-tuple ``(host, port)`` for the socket to bind to as |

| 198 | .. method:: FTP.getwelcome() |
| 199 | |
| 200 | Return the welcome message sent by the server in reply to the initial |
| 201 | connection. (This message sometimes contains disclaimers or help information |
| 202 | that may be relevant to the user.) |
| 203 | |
| 204 | |
Georg Brandl | 036490d | 2009-05-17 13:00:36 +0000 | [diff] [blame] | 205 | .. method:: FTP.login(user='anonymous', passwd='', acct='') |
Georg Brandl | 116aa62 | 2007-08-15 14:28:22 +0000 | [diff] [blame] | 206 | |
| 207 | Log in as the given *user*. The *passwd* and *acct* parameters are optional and |
| 208 | default to the empty string. If no *user* is specified, it defaults to |
| 209 | ``'anonymous'``. If *user* is ``'anonymous'``, the default *passwd* is |
| 210 | ``'anonymous@'``. This function should be called only once for each instance, |
| 211 | after a connection has been established; it should not be called at all if a |
| 212 | host and user were given when the instance was created. Most FTP commands are |
Benjamin Peterson | 8719ad5 | 2009-09-11 22:24:02 +0000 | [diff] [blame] | 213 | only allowed after the client has logged in. The *acct* parameter supplies |
| 214 | "accounting information"; few systems implement this. |
Georg Brandl | 116aa62 | 2007-08-15 14:28:22 +0000 | [diff] [blame] | 215 | |
| 216 | |
| 217 | .. method:: FTP.abort() |
| 218 | |

| 220 | it's worth a try. |

Georg Brandl | 116aa62 | 2007-08-15 14:28:22 +0000 | [diff] [blame] | 289 | |
| 290 | Initiate a transfer over the data connection. If the transfer is active, send a |
| 291 | ``EPRT`` or ``PORT`` command and the transfer command specified by *cmd*, and |
| 292 | accept the connection. If the server is passive, send a ``EPSV`` or ``PASV`` |
| 293 | command, connect to it, and start the transfer command. Either way, return the |
| 294 | socket for the connection. |
| 295 | |
| 296 | If optional *rest* is given, a ``REST`` command is sent to the server, passing |
| 297 | *rest* as an argument. *rest* is usually a byte offset into the requested file, |
| 298 | telling the server to restart sending the file's bytes at the requested offset, |
| 299 | skipping over the initial bytes. Note however that RFC 959 requires only that |
| 300 | *rest* be a string containing characters in the printable range from ASCII code |
| 301 | 33 to ASCII code 126. The :meth:`transfercmd` method, therefore, converts |
| 302 | *rest* to a string, but no check is performed on the string's contents. If the |
| 303 | server does not recognize the ``REST`` command, an :exc:`error_reply` exception |
| 304 | will be raised. If this happens, simply call :meth:`transfercmd` without a |
| 305 | *rest* argument. |
