Question

I want to create a valid URL to send to Windows File Explorer (or other file managers like TotalCommander) using the format:

ftp://username:password@ftp.domain.ext/folder/

In Explorer, it works with very straight username and password. But I receive errors (or Explorer just display the My Document instead of the FTP site) when password contains certain special characters. I played with URI encoding to encode the password with some success but not 100% reliable.

Can someone help me finding the correct requirements for a valid FTP URL including username and password? Thanks.

Here is a sample of the code using AutoHotkey "Run" command (on Windows 7 64-bit environment):

#NoEnv
#SingleInstance force

strFTPUrl := "ftp://www.jeanlalonde.ca"

strLoginName := "username@jeanlalonde.ca"
strPassword := "********"

StringReplace, strFTPUrl, strFTPUrl, % "ftp://", % "ftp://" . strLoginName . ":" . UriEncode(strPassword) . "@"

; Before: ftp://ftp.jeanlalonde.ca
; After: ftp://testaccount@jeanlalonde.ca:********@ftp.jeanlalonde.ca
MsgBox, %strFTPUrl%

Run, Explorer "%strFTPUrl%"

return

如果用户名中也有特殊字符（@为一个）（不仅仅是密码），您也必须对用户名进行URL编码，就像对密码进行URL编码一样。 / p>

这意味着您必须将UriEncode应用于strLoginName，就像将其应用于strPassword一样。

您需要更新UriEncode以对@进行编码，因为它不会。

@的代码为0x40。

if ((ch>0x7f) || (ch<0x30) || (ch=0x3d) || (ch=0x40))

（虽然您也可以与@字面上进行比较：ch="@"）。
