## 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:

- old NSISdl style - additional embedded progress bar and text on the INSTFILES page;
- POPUP dialog mode with detailed info;
- 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. For ftp use "host/path" for file location relative to user's home dir and "host//path" for absolute path.

## Commands

Plug-in DLL functions (entry points): get, post, head, put

### get

inetc::get [/PROXY IP:PORT] [/USERNAME PROXY_LOGIN /PASSWORD PROXY_PASSWD] [/NOCOOKIES] [/NOPROXY] [/NOCANCEL] [/CONNECTTIMEOUT TO_SEC] [/RECEIVETIMEOUT TO_SEC] [/SILENT] [/WEAKSECURITY] [/CAPTION TEXT] [/NOCOOKIES] [/RESUME RETRY_QUESTION] [/POPUP HOST_ALIAS | /BANNER TEXT] [/CANCELTEXT CANCEL_TEXT] [/QUESTION CANCEL_QUESTION] [/USERAGENT USER_AGENT_TEXT] [/HEADER HEADER_TEXT] [/TRANSLATE LANG_PARAMS] [/TOSTACK | /TOSTACKCONV] 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, removes sysmenu)

/CONNECTTIMEOUT - Sets INTERNET_OPTION_CONNECT_TIMEOUT, seconds, default - IE current parameter value.

/RECEIVETIMEOUT - Sets INTERNET_OPTION_RECEIVE_TIMEOUT, seconds, default - IE current parameter value.

/SILENT - Key hides plug-in' output (both popup dialog and embedded progress bar). Not required if 'SilentInstall silent' mode was defined in script (NSIS 2.03 or later).

/WEAKSECURITY - Ignore unknown and revoked certificates

/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...".

/CAPTION - Defines caption text for /BANNER mode, caption prefix (left of '-') for /POPUP mode and caption for RESUME MessageBox. Default is "InetLoad plug-in" if not set or "". 127 chars maximum.

/POPUP - This mode displays detailed download dialog instead of embedded progress bar. Also useful in .onInit function (i.e. not in Section). If HOST_ALIAS is not "", text will replace URL in the dialog - this allows to hide real URL (including password).

/BANNER - Displays simple popup dialog (MSI Banner mode) and sets dialog TEXT (up to 3 lines using $\n).

/CANCELTEXT - Text for the Cancel button in the NSISdl mode. Default is NSIS dialog Cancel button text (current lang).

/QUESTION - Text for the optional MessageBox if user tries to cancel download. If /QUESTION "" was used default "Are you sure that you want to stop download?" will be substituted.

/USERAGENT - UserAgent http request header value. Default is "NSIS_Inetc (Mozilla)". 256 chars maximum.

/HEADER - Adds or replaces http request header. Common HEADER_TEXT format is "header: value".

/NOCOOKIES - Removes cookies from http request

/TOSTACK - Outputs the post/get/head response to the NSIS stack rather than to the file (specify an empty string for local_file1, local_file2 etc.)

/TOSTACKCONV - Outputs the post/get/head response to the NSIS stack while converting character encodings:
ASCII -> Unicode for the Unicode plug-in build
Unicode -> ASCII for the ASCII plug-in build

/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 NSISdl modes. 8 parameters both cases.
NSISdl mode parameters:
/TRANSLATE downloading connecting second minute hour plural progress remaining
With default values:
"Downloading %s" "Connecting ..." second minute hour s "%dkB (%d%%) of %dkB @ %d.%01dkB/s" "(%d %s%s remaining)"
POPUP mode parameters:
/TRANSLATE url downloading connecting file_name received file_size remaining_time total_time
With default values:
URL Downloading Connecting "File Name" Received "File Size" "Remaining Time" "Total Time"

### post

inetc::post TEXT2POST [/FILE] [/PROXY IP:PORT] [/NOPROXY] [/NOCANCEL] [/USERNAME PROXY_LOGIN /PASSWORD PROXY_PASSWD] [/TIMEOUT INT_MS] [/SILENT] [/WEAKSECURITY] [/CAPTION TEXT] [/POPUP | /BANNER TEXT] [/CANCELTEXT CANCEL_TEXT] [/USERAGENT USER_AGENT_TEXT] [/TRANSLATE LANG_PARAMS] [/TOSTACK | /TOSTACKCONV] URL1 local_file1 [URL2 local_file2 [...]] [/END]

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). If /FILE presents in command line, TEXT2POST is filename to be sent in POST request. Also 'Filename:' header will be added to HTTP headers.

### head

The same as get, but requests http headers only. Writes raw headers to file.

### put

inetc::put [/PROXY IP:PORT] [/USERNAME PROXY_LOGIN /PASSWORD PROXY_PASSWD] [/NOPROXY] [/NOCANCEL] [/TIMEOUT INT_MS] [/SILENT] [/WEAKSECURITY] [/CAPTION TEXT] [/POPUP | /BANNER TEXT] [/CANCELTEXT CANCEL_TEXT] [/USERAGENT USER_AGENT_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::put "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
      Abort
    dlok:
      ...

## Credits

Many thanks to Backland who offered a simple way to fix NSISdl mode crashes, added 'center parent' function, offers few nice design ideas and spent a lot of time testing the plug-in.
