FTP

+ +

+FTP (File Transfer Protocol) is a protocol used to transfer files +between hosts. The ftp namespace offers thorough support +to FTP, under a simple interface. The implementation conforms to +RFC 959. +

+ +

+High level functions are provided supporting the most common operations. +These high level functions are implemented on top of a lower level +interface. Using the low-level interface, users can easily create their +own functions to access any operation supported by the FTP +protocol. For that, check the implementation. +

+ +

+To really benefit from this module, a good understanding of + +LTN012, Filters sources and sinks is necessary. +

+ +

+To obtain the ftp namespace, run: +

+ +
+-- loads the FTP module and any libraries it requires
+local ftp = require("socket.ftp")
+
+ +

+URLs MUST conform to +RFC 1738, +that is, an URL is a string in the form: +

+ +
+ +[ftp://][<user>[:<password>]@]<host>[:<port>][/<path>][type=a|i] +
+ +

+The following constants in the namespace can be set to control the default behavior of +the FTP module: +

+ + + + + + +

+ftp.get(url)
+ftp.get{
+  host = string,
+  sink = LTN12 sink,
+  argument or path = string,
+  [user = string,]
+  [password = string]
+  [command = string,]
+  [port = number,]
+  [type = string,]
+  [step = LTN12 pump step,]
+  [create = function]
+} +

+ +

+The get function has two forms. The simple form has fixed +functionality: it downloads the contents of a URL and returns it as a +string. The generic form allows a lot more control, as explained +below. +

+ +

+If the argument of the get function is a table, the function +expects at least the fields host, sink, and one of +argument or path (argument takes +precedence). Host is the server to connect to. Sink is +the simple +LTN12 +sink that will receive the downloaded data. Argument or +path give the target path to the resource in the server. The +optional arguments are the following: +

+ + +

+If successful, the simple version returns the URL contents as a +string, and the generic function returns 1. In case of error, both +functions return nil and an error message describing the +error. +

+ +
+-- load the ftp support
+local ftp = require("socket.ftp")
+
+-- Log as user "anonymous" on server "ftp.tecgraf.puc-rio.br",
+-- and get file "lua.tar.gz" from directory "pub/lua" as binary.
+f, e = ftp.get("ftp://ftp.tecgraf.puc-rio.br/pub/lua/lua.tar.gz;type=i")
+
+ +
+-- load needed modules
+local ftp = require("socket.ftp")
+local ltn12 = require("ltn12")
+local url = require("socket.url")
+
+-- a function that returns a directory listing
+function nlst(u)
+    local t = {}
+    local p = url.parse(u)
+    p.command = "nlst"
+    p.sink = ltn12.sink.table(t)
+    local r, e = ftp.get(p)
+    return r and table.concat(t), e
+end
+
+ + + +

+ftp.put(url, content)
+ftp.put{
+  host = string,
+  source = LTN12 sink,
+  argument or path = string,
+  [user = string,]
+  [password = string]
+  [command = string,]
+  [port = number,]
+  [type = string,]
+  [step = LTN12 pump step,]
+  [create = function]
+} +

+ +

+The put function has two forms. The simple form has fixed +functionality: it uploads a string of content into a URL. The generic form +allows a lot more control, as explained below. +

+ +

+If the argument of the put function is a table, the function +expects at least the fields host, source, and one of +argument or path (argument takes +precedence). Host is the server to connect to. Source is +the simple +LTN12 +source that will provide the contents to be uploaded. +Argument or +path give the target path to the resource in the server. The +optional arguments are the following: +

+ + +

+Both functions return 1 if successful, or nil and an error +message describing the reason for failure. +

+ +
+-- load the ftp support
+local ftp = require("socket.ftp")
+
+-- Log as user "fulano" on server "ftp.example.com",
+-- using password "silva", and store a file "README" with contents 
+-- "wrong password, of course"
+f, e = ftp.put("ftp://fulano:silva@ftp.example.com/README", 
+    "wrong password, of course")
+
+ +
+-- load the ftp support
+local ftp = require("socket.ftp")
+local ltn12 = require("ltn12")
+
+-- Log as user "fulano" on server "ftp.example.com",
+-- using password "silva", and append to the remote file "LOG", sending the
+-- contents of the local file "LOCAL-LOG"
+f, e = ftp.put{
+  host = "ftp.example.com", 
+  user = "fulano",
+  password = "silva",
+  command = "appe",
+  argument = "LOG",
+  source = ltn12.source.file(io.open("LOCAL-LOG", "r"))
