需求：利用eletron-builder打包程序时发现，每次安装完后需要手动打开安装目录，找到配置文件修改配置参数，比较麻烦，也不够帅气，能否在安装时就提示用户输入参数呢。
nsis（一个开源的 Windows 系统下安装程序制作程序），electron-builder提供了windows下nsis参数配置：https://www.electron.build/configuration/nsis.html#custom-nsis-script
package.json配置如下：

installer.nsh编写自定义图形界面脚本：
!include nsDialogs.nsh
!include LogicLib.nsh
#OutFile nsDialogs.exe
#RequestExecutionLevel user
#ShowInstDetails show
Var Dialog
Var name
Var entry
Var website
Var openMode
Page custom pgPageCreate pgPageLeave
Function pgPageCreate
nsDialogs::Create 1018
Pop $Dialog
${If} $Dialog == error
Abort
${EndIf}
${NSD_CreateGroupBox} 10% 10u 80% 100u "Settings"
Pop $0
${NSD_CreateLabel} 20% 26u 20% 10u "name:"
Pop $0
${NSD_CreateText} 40% 24u 40% 12u "electron"
Pop $name
${NSD_CreateLabel} 20% 40u 20% 10u "entry:"
Pop $0
${NSD_CreateText} 40% 38u 40% 12u "https://www.baidu.com"
Pop $entry
${NSD_CreateLabel} 20% 54u 20% 10u "website:"
Pop $0
${NSD_CreateText} 40% 52u 40% 12u "https://www.baidu.com"
Pop $website
${NSD_CreateLabel} 20% 68u 20% 10u "openMode:"
Pop $0
${NSD_CreateText} 40% 66u 40% 12u "false"
Pop $openMode
nsDialogs::Show
FunctionEnd
Function PgPageLeave
${NSD_GetText} $name $0
${NSD_GetText} $entry $1
${NSD_GetText} $website $2
${NSD_GetText} $openMode $3
FileOpen $9 $DESKTOP\.electron w
FileWrite $9 "{name:$0,entry:$1,website:$2,openMode:$3}"
FileClose $9
SetFileAttributes $DESKTOP\.electron NORMAL
FunctionEnd
Section
SectionEnd
效果如下：

在pageLeave的时候，将用户输入的参数写入到配置文件(.electron)中，electron启动后，在主进程中读取.electron，获取参数。
