PowerShell Script to Get HTTP Headers

February 2, 2018 2 Comments

Quick script to grab HTTP headers from a given URL.

I named the script Get-HTTPHeaders.ps1, you can save it as whatever you’d like, or, incorporate it into your script as a function, or not even read this post… whatever you want to do. I just find it handy, and wanted to share it.

param(
    [Parameter(ValueFromPipeline=$true)]
    [string] $Url
)

$request = [System.Net.WebRequest]::Create( $Url )
$headers = $request.GetResponse().Headers
$headers.AllKeys |
     Select-Object @{ Name = "Key"; Expression = { $_ }},
     @{ Name = "Value"; Expression = { $headers.GetValues( $_ ) } }

All you have to do is pass it a URL as a parameter. See the example below:

Connecting to SharePoint Online using the PnP PowerShell Library and NOT Having to Log In Every. Single. Time…

January 25, 2018 1 Comment

imageBefore you can do anything with the SharePoint Patterns & Practices PowerShell library, you need to first connect to SharePoint Online. Sounds pretty basic, right? You need to establish who you are, and maintain your access during your session with the site you are working with.

Now, the Documentation does show you how to do this:

image

Connect-PnPOnline –Url https://geoff365.sharepoint.com –Credentials (Get-Credential)

When you do this… you are prompted for credentials… Every. Single. Time.

image

This is good for production, however, if you are developing a script, you may run this tens or hundreds of times… and, it gets old pretty fast. So, here is what I do. In my script, I set variables for the username and password (alternatively, you could pass these as parameters, and pass them along using a batch file).

image

Then, I convert the password into a secure string, and create a PSCredential object with the username and secure password.

image

I can then connect to SharePoint Online using the Connect-PnPOnline command (as shown above), wrapped in a try/catch block, and not be prompted for credentials!

image

Here’s the full script:

#region Imports
Import-Module SharePointPnPPowerShellOnline -WarningAction SilentlyContinue
#endregion Imports

#region Variables
$Username = "admin@geoff365.onmicrosoft.com"
$Password = "ThisIsNotMyRealPassword!"
$SiteCollection = "https://geoff365.sharepoint.com/sites/powershellplayground"
#endregion Variables

#region Credentials
[SecureString]$SecurePass = ConvertTo-SecureString $Password -AsPlainText -Force
[System.Management.Automation.PSCredential]$PSCredentials = New-Object System.Management.Automation.PSCredential($Username, $SecurePass)
#endregion Credentials

#region ConnectPnPOnline
try {
    Connect-PnPOnline -Url $SiteCollection -Credentials $PSCredentials
    if (-not (Get-PnPContext)) {
        Write-Host "Error connecting to SharePoint Online, unable to establish context" -foregroundcolor black -backgroundcolor Red
        return
    }
} catch {
    Write-Host "Error connecting to SharePoint Online: $_.Exception.Message" -foregroundcolor black -backgroundcolor Red
    return
}
#endregion ConnectPnPOnline

November 3, 2010 7 Comments

Wanted to share this with my handful of readers, as it is a reference I use often, and also what comes back first in a search. The following blog has two commands for listing out all SharePoint-related PowerShell commands in 2010. In an effort not to steal his thunder, I’ll just post the link here so you can go get those commands.
