    我脑子更不好使, 完全看不懂, 大佬如果懂原理, 用gpt估计能搞出来, 我不行, gpt不听我使唤

用 curl.exe --parallel  在gpt中死活就是搞不成功, ai还是太弱智了, 哎

# 定义文件的URL和保存路径
$urls = @(
    "https://dldir1v6.qq.com/weixin/Windows/WeChatSetup.exe",
    "https://dldir1.qq.com/qqfile/qq/QQNT/Windows/QQ_9.9.15_240902_x64_01.exe",
    "https://dldir1.qq.com/qqfile/qq/TIM3.5.0/TIM3.5.0.22143.exe"
)

# 获取桌面路径
$desktop = [System.Environment]::GetFolderPath('Desktop')

# 使用 curl.exe 并行下载，重定向输出到 $null 以避免 PowerShell 处理输出内容
& curl.exe --parallel `
    --output "$desktop\WeChatSetup.exe" $urls[0] `
    --output "$desktop\QQ_9.9.15.exe" $urls[1] `
    --output "$desktop\TIM3.5.0.exe" $urls[2] `
    *> $null

多谢大佬, powershell不是支持并行处理吗?
我用gpt生成了如下代码, 能执行成功, 但是没有进度条, 发现gpt还是不够智能, N多轮才能搞成

# 定义文件的URL和保存路径
$urls = @(
    "https://dldir1v6.qq.com/weixin/Windows/WeChatSetup.exe",
    "https://dldir1.qq.com/qqfile/qq/QQNT/Windows/QQ_9.9.15_240902_x64_01.exe",
    "https://dldir1.qq.com/qqfile/qq/TIM3.5.0/TIM3.5.0.22143.exe"
)

# 获取桌面路径
$desktop = [System.Environment]::GetFolderPath('Desktop')

# 创建一个存储作业的数组
$jobs = @()

# 启动并行下载作业
foreach ($url in $urls) {
    $fileName = Split-Path $url -Leaf
    $outputPath = Join-Path $desktop $fileName

    $jobs += Start-Job -ScriptBlock {
        param($downloadUrl, $savePath)
        Invoke-WebRequest -Uri $downloadUrl -OutFile $savePath
    } -ArgumentList $url, $outputPath
}

# 等待所有作业完成
$jobs | ForEach-Object {
    Wait-Job $_
    Remove-Job $_
}

Write-Host "所有文件下载完成！"

往下载对象里订阅添加
DownloadStarted
ChunkDownloadProgressChanged
DownloadProgressChanged
DownloadFileCompleted
这四个事件(参考示例源码,在事件里写进度条代码)

我脑子不好,不会弄进度条这些特效代码,反正那源码用的是ShellProgressBar,你可以试试http://www.nuget.org/packages/ShellProgressBar/

powershell对多线程有限制,用curl.exe --parallel更快
