Description

Internet client plug-in for files download and upload. Based on the InetLoad plug-in. Network implementation uses MS WinInet API, supports http/https and ftp protocols. Plugin has better proxy support compare to NSISdl plug-in. Command line may include few URL/File pairs to be transfered. If server or proxy login/password are not setten in the script, displays IE-style authentication dialog (except silent mode). Plug-in supports 3 "transfer in progress" display modes:

  1. old NSISdl style - additional embedded progress bar and text on the INSTFILES page;
  2. POPUP dialog mode with detailed info;
  3. BANNER mode with simple popup window.

Plug-in recognizes Installer's Silent mode and this case hides any output (this feature requires NSIS 2.03 or later). Program implements simple re-get functionality - host reconnect and download from current position after short pause. While program depends on IE settings, it changes current IE mode to online. NSISdl code fragment was used for progress bar displaying in the "old style" mode.

Command line

Plug-in DLL functions (entry points): play, stop, auth

get DLL Function

inetc::get [/PROXY IP:PORT] [/USERNAME PROXY_LOGIN /PASSWORD PROXY_PASSWD]
 [/NOPROXY] [/NOCANCEL] [/POST TEXT2POST] [/TIMEOUT INT_MS] [/SILENT TEXT2DISPLAY]
 [/RESUME RETRY_QUESTION] [/POPUP PREFIX | /BANNER CAPTION TEXT] [/TRANSLATE LANG_PARAMS]
 URL1 local_file1 [URL2 local_file2 [...]] [/END]

This call returns "OK" string if successful, error description string if failed (see included InetLoad.cpp file for a full set of status strings). Usage and result processing samples are included to the package.

/PROXY
Overwrites current proxy settings, not required in most cases. IE settings will be used by default.
/USERNAME
Proxy username (http only).
/PASSWORD
Proxy password (http only). For server (http/ftp) authentication it is possible to use URL encoded name and password, for example http://username:password@nsis.sourceforge.net.
/NOPROXY
Disables proxy settings for this connection (if any)
/NOCANCEL
Prevents download from being interrupted by user (locks Esc, Alt-F4, Cancel handling)
/POST
Sets POST http mode and defines text string to be used in the POST (http only). Disables auto re-get. No char replaces used (%20 and others).
/TIMEOUT
Sets INTERNET_OPTION_CONNECT_TIMEOUT, milliseconds, default - IE current parameter value.
/SILENT
Key hides plug-in' output (both popup dialog and embedded progress bar). Sets TEXT2DISPLAY to 1006 control, if /silent "" - displays "InetLoad plug-in" default. Not required if 'SilentInstall silent' mode was defined in script (NSIS 2.03 option).
/RESUME
On the permanent connection/transfer error instead of exit first displays message box with "resume download" question. Useful for dial-up connections and big files - allows user to restore connection and resume download. Default is "Your internet connection seems to have dropped out!\nPlease reconnect and click Retry to resume downloading...".
/POPUP
This mode displays detailed download dialog instead of embedded progress bar. PREFIX parameter sets left part of dialog caption (before '-'), default is "InetLoad plug-in" (if ""). Also useful in .onInit function (i.e. not in Section).
/BANNER
Displays simple popup dialog (MSI Banner mode) and sets dialog CAPTION ("NSIS Installer - InetLoad" is default) and TEXT (up to 3 lines using $\n).
/END
Allows to limit plug-in stack reading (optional, required if you stores other vars in the stack).
/TRANSLATE
Allows translating plug-in text in the POPUP or "old style" (NSISdl) modes (see Readme for parameters). In the BANNER mode text is also customizable.

put DLL Function

inetc::put [/PROXY IP:PORT] [/USERNAME PROXY_LOGIN /PASSWORD PROXY_PASSWD] [/NOPROXY]
 [/NOCANCEL] [/TIMEOUT INT_MS] [/SILENT TEXT2DISPLAY] [/POPUP PREFIX | /BANNER CAPTION TEXT] 
 [/TRANSLATE LANG_PARAMS] URL1 local_file1 [URL2 local_file2 [...]] [/END]

Return value and parameters (if applicable) are the same as for previous entry point.

Examples

inetc::get "http://dl.zvuki.ru/6306/mp3/12.mp3" "$EXEDIR\12.mp3" \
               "ftp://dl.zvuki.ru/6306/mp3/11.mp3" "$EXEDIR\11.mp3"
Pop $0
inetc::put /BANNER "" "Cameron Diaz upload in progress..." \
"http://www.dreamgirlswallpaper.co.uk/fiveyearsonline/wallpaper/Cameron_Diaz/camerond09big.JPG" \
"$EXEDIR\cd.jpg"
  Pop $0
  StrCmp $0 "OK" dlok
  MessageBox MB_OK|MB_ICONEXCLAMATION "http upload Error, click OK to abort installation" /SD IDOK
