与代理的RCurl sftp连接

Question

我一直在尝试用RCurl和SFTP连接和列出文件。我可以通过WinSCP访问，但是RCurl不能通过。这就是我目前所在的位置：

library(RCurl)

opts <- curlOptions(
  proxy         = "http://myproxy/",
  proxyport     = 8080,
  httpproxytunnel = 1L,
  ssh.private.keyfile = "ssh-gibberish"
)

url <- "sftp://user:pwd@ftp.address.com/"

test <- getURL(url = url, .opts = opts, dirlistonly = TRUE, verbose = TRUE, port = 22)

*   Trying 123.12.123.12...
* Connected to myproxy (123.12.123.12) port 8080 (#0)
* Establish HTTP proxy tunnel to ftp.address.com:22
> CONNECT ftp.address.com:22 HTTP/1.1
Host: ftp.address.com:22
Proxy-Connection: Keep-Alive

* Proxy CONNECT aborted
* Connection #0 to host myproxy left intact
Error in function (type, msg, asError = TRUE)  : Proxy CONNECT aborted

终于解决了。我不得不更改代理并添加用户名和密码。

opts <- curlOptions(
  proxy         = "http://mynewproxy/",
  proxyport     = 8080,
  proxyusername = "domain\\user", 
  proxypassword = "pwd", 
  httpproxytunnel = 1L,
  ssh.private.keyfile = "ssh-gibberish"
)

代理通常使用windows passowrds，但我想这是不同的。
