检查密码保护的web文件是否存在。

Question

我需要检查一下是否有一个受密码保护的web文件存在于目录中。

我一直得到一个(401) Unauthorized错误，所以，第5-6行不工作.

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？

您使用两个对象WebClient和WebRequest，只需要一个。

您将凭据设置为WebClient，但在没有凭据的情况下通过WebRequest进行响应。

将代码修改为：

    $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()
