Powershell BitsTransfer https基本身份验证语法 [英] Powershell BitsTransfer https basic authentication syntax

问题描述

我是PowerShell脚本的新手.我在MS文档方面苦苦挣扎，并发现了一些可以使用的示例.

I'm new to PowerShell scripting. I'm struggling with the MS documentation and finding few examples to work with.

我正在尝试使用BitsTransfer脚本每周自动从ntis.gov下载大型txt文件.我使用的是.ps1脚本，因为显然SSIS如果不编写.NET代码就无法做到这一点.

I'm trying to automate the weekly download of a large txt file from ntis.gov with a BitsTransfer script. I'm using .ps1 script because apparently SSIS can't do this without writing .NET code.

通过https:使用NTIS颁发的用户名和密码访问此文本文件.如何在身份验证字符串中指定(硬编码)密码?我知道这是不好的做法.有更好的方法吗?

Access to this text file is via https: with an NTIS issued username and password. How can I specify (hard code) the password into the authentication string? I know this is bad practice. Is there a better way to do this?

我的脚本看起来像这样-

My script looks like this-

    $date= Get-Date -format yyMMdd
    Import-Module BitsTransfer
    $Job = Start-BitsTransfer `
    -DisplayName DMFweeklytrans `
    -ProxyUsage AutoDetect `
    -Source https://dmf.ntis.gov/dmldata/weekly/WA$date `
    -Destination D:\Test.txt `
    -Authentication Basic `
    -Credential "myIssuedUsername" `
    -Asynchronous

While (($Job.JobState -eq "Transferring") -or ($Job.JobState -eq "Connecting")) {sleep 5}
Switch($Job.JobState)
    {
        "Transfer Completed" {Complete-BitsTransfer -BitsJobs $Jobs}
        default {$Job | Format-List} 
    }

推荐答案

当您必须以非交互方式提供凭据时，可以通过以下方式创建PSCredential对象.

When you have to provide credentials in non-interactive mode, you can create a PSCredential object in the following way.

$secpasswd = ConvertTo-SecureString "PlainTextPassword" -AsPlainText -Force
$yourcreds = New-Object System.Management.Automation.PSCredential ("username", $secpasswd)

$Job = Start-BitsTransfer `
    -DisplayName DMFweeklytrans `
    -ProxyUsage AutoDetect `
    -Source https://dmf.ntis.gov/dmldata/weekly/WA$date `
    -Destination D:\Test.txt `
    -Authentication Basic `
    -Credential $yourcreds `
    -Asynchronous
