Question

我需要检查目录中是否存在受密码保护的Web文件。

我不断收到(401) Unauthorized错误，因此第5-6行无效。

脚本代码：

$currdate = Get-Date -format "yyyyMMdd"
$Username = "username"
$Password = "password"
$url = "http://some.website/" + $currdate + "/somedirectory/some.file.txt"
$WebClient = New-Object System.Net.WebClient
$WebClient.Credentials = New-Object System.Net.Networkcredential($Username, $Password)
$HTTP_Request = [System.Net.WebRequest]::Create($url)
$HTTP_Response = $HTTP_Request.GetResponse()
$HTTP_Status = [int]$HTTP_Response.StatusCode
If ($HTTP_Status -eq 200) { 
    Write-Host "File exists!" 
}
Else {
    Write-Host "File does not exist..."
}
$HTTP_Response.Close()

我做错了什么？

Answer 1

您使用WebClient和WebRequest这两个对象，只需要一个。

您可以将凭据设置为WebClient，但您可以通过WebRequest进行响应，而无需凭据。

将您的代码修改为：

    $currdate = Get-Date -format "yyyyMMdd"
    $Username = "xxxxx"
    $Password = "xxxxxx"
    $url = "http://some.website/" + $currdate + "/somedirectory/some.file.txt"      

    # comment these lines,you use WebRequest
    #$WebClient = New-Object System.Net.WebClient
    #$WebClient.Credentials = New-Object System.Net.Networkcredential($Username, $Password)

    $HTTP_Request = [System.Net.WebRequest]::Create($url)

    #add this line
    $HTTP_Request.Credentials = new-object system.net.networkcredential($Username, $Password)

    $HTTP_Response = $HTTP_Request.GetResponse()
    $HTTP_Status = [int]$HTTP_Response.StatusCode
    If ($HTTP_Status -eq 200) { 
        Write-Host "File exists!" 
    }
    Else {
        Write-Host "File does not exist..."
    }
    $HTTP_Response.Close()
