NSIS 异步文件下载和自定义进度条

Question

是否存在 NSIS 插件或内置功能来异步下载文件并使用下载进度更新自定义进度条（使用 nsDialogs 创建）？

Answer 1

您可以使用INetBgDl plugin在后台下载文件并设计您自己的UI:

!include nsDialogs.nsh
!include LogicLib.nsh
Var hInfo
Var hPBar

Function myTimer
InetBgDL::GetStats
${If}  = 0
    ${NSD_KillTimer} myTimer
    ${NSD_SetText} $hInfo "Completed. (Status=[=10=])"
    SendMessage $hPBar ${PBM_SETRANGE32} 0 100
    SendMessage $hPBar ${PBM_SETPOS} 100 0
    Return
${EndIf}
IntOp   + 
StrCmp  "" 0 +2
StrCpy  "?"
${NSD_SetText} $hInfo "Status=[=10=]$\nCompleted  of  files$\nDownloaded  of  bytes"
SendMessage $hPBar ${PBM_SETRANGE32} 0 
SendMessage $hPBar ${PBM_SETPOS}  0
FunctionEnd

Function myPage
nsDialogs::Create 1018
Pop [=10=]

${NSD_CreateLabel} 0 0 100% 50% "Starting download..."
Pop $hInfo

${NSD_CreateProgressBar} 0 55% 100% 10u ""
Pop $hPBar

${NSD_CreateTimer} myTimer 1000
InetBgDL::Get /RESET "https://download.mozilla.org/?product=firefox-41.0.2-SSL&os=win&lang=en-US" "$PluginsDir\ff.exe" /END

nsDialogs::show
${NSD_KillTimer} myTimer
FunctionEnd
