NSIS 打包（二）InetLoad::load下载文件

InetLoad::load

InetLoad::load [/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]

/PROXYOverwrites current proxy settings, not required in most cases. IE settings will be used by default./USERNAMEProxy username (http only)./PASSWORDProxy 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./NOPROXYDisables proxy settings for this connection (if any)/NOCANCELPrevents download from being interrupted by user (locks Esc, Alt-F4, Cancel handling)/POSTSets 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)./TIMEOUTSets INTERNET_OPTION_CONNECT_TIMEOUT, milliseconds, default - IE current parameter value./SILENTKey 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)./RESUMEOn 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..."./POPUPThis 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)./BANNERDisplays simple popup dialog (MSI Banner mode) and sets dialog CAPTION ("NSIS Installer - InetLoad" is default) and TEXT (up to 3 lines using $\n)./ENDAllows to limit plug-in stack reading (optional, required if you stores other vars in the stack)./TRANSLATEAllows translating plug-in text in the POPUP or "old style" (NSISdl) modes (see Readme for parameters). In the BANNER mode text is also customizable.

设定压缩比

SetCompressor
[/SOLID] [/FINAL] \\zlib\\|bzip2|lzma
该命令设置了安装程序压缩文件、数据使用的压缩算法。该命令只能在区段、函数之外或在任何数据被压缩之前使用。不同的压缩方式不能在同一个安装程序里用来压缩不同的文件。建议在脚本的开始处使用这个命令来尽可能避免编译错误。

支持三种压缩方式: ZLIB, BZIP2 和 LZMA 。

ZLIB (默认) 使用压缩算法，是一个快速简单的方法。默认的压缩级别它消耗大约 300 KB 内存。

BZIP2 通常比 ZLIB 的压缩率好，但是稍微慢了一点并且内存的使用也多一点。默认的压缩级别它消耗大约 4 MB 内存。

LZMA 是一个压缩率比较理想的新式压缩方式。它的解压速度非常快(在 2 GHz 的 CPU 上能达到 10-20 MB/s 的速度)，但是压缩速度很慢。解压时内存的使用量是字典的大小加上一些 KB ，默认值为 8 MB 。

如果使用了 /FINAL ，则 SetCompressor 后来的调用都会被忽略。

如果使用了 /SOLID 的话，所有的数据将被压缩在一个区块里，这样可以提高压缩率。
