Download a File From SharePoint Online Using Python

How do you download a file from a SharePoint Online library using Python?

Items needed to run the script in this example:
Install and run a simple Python script.
Office365 Rest Python Client library:
https://pypi.org/project/Office365-REST-Python-Client/
SharePoint App Only Client Id and Secret:
Microsoft documentation:
https://docs.microsoft.com/en-us/sharepoint/dev/solution-guidance/security-apponly-azureacs
You can create an app principle that is limited to a single site, list, library, or a combination of them:

from office365.runtime.auth.authentication_context import AuthenticationContext
from office365.sharepoint.client_context import ClientContext
from office365.sharepoint.files.file import File

app_settings = {
    'url': 'https://YOURtenant.sharepoint.com/sites/somesite/',
    'client_id': '12344-abcd-efgh-1234-1a2d12a21a2121a',
    'client_secret': 'Oamytacohungry234343224534543=',
}

context_auth = AuthenticationContext(url=app_settings['url'])
context_auth.acquire_token_for_app(client_id=app_settings['client_id'], client_secret=app_settings['client_secret'])

ctx = ClientContext(app_settings['url'], context_auth)
web = ctx.web
ctx.load(web)
ctx.execute_query()

response = File.open_binary(ctx, "/Shared Documents/Invoice.pdf")
with open("./Invoice.pdf", "wb") as local_file:
    local_file.write(response.content)

If the above script does not work, take a step back and make sure you are connected to the site.

from office365.runtime.auth.authentication_context import AuthenticationContext
from office365.sharepoint.client_context import ClientContext
from office365.sharepoint.files.file import File

app_settings = {
    'url': 'https://YOURtenant.sharepoint.com/sites/somesite/',
    'client_id': '12344-abcd-efgh-1234-1a2d12a21a2121a',
    'client_secret': 'Oamytacohungry234343224534543=',
}

context_auth = AuthenticationContext(url=app_settings['url'])
context_auth.acquire_token_for_app(client_id=app_settings['client_id'], client_secret=app_settings['client_secret'])

ctx = ClientContext(app_settings['url'], context_auth)
web = ctx.web
ctx.load(web)
ctx.execute_query()

print("Site title: {0}".format(web.properties['Title']))

How to use an iFrame in a modern SharePoint Online page

Using the Embed web part I was trying to paste in a site URL when I should have been using the iFrame HTML tag.

example:

<iframe src="https://sharepointed.com" height="200" width="300"></iframe>

If you encounter this error: This website doesn’t support embedding using just the address ….

You will need to update the HTML Field Security settings in the Site Settings area of your site. In my case, I simply added sharepointed.com to the allow iframes from this domain list, then updated the web part again.

Connect to SharePoint Online Using PowerShell

Update and a much better way to approach this:
Use a SharePoint App Only Client Id and Secret to access the site, list, or library.

Microsoft documentation:
https://docs.microsoft.com/en-us/sharepoint/dev/solution-guidance/security-apponly-azureacs
You can create an app principle that is limited to a single site, list, library, or a combination of them:
https://piyushksingh.com/2018/12/26/register-app-in-sharepoint/

 $sampleConnect = Connect-PnPOnline -Url "https://YOURsite.sharepoint.com/sites/parent/child" -AppId "12345-94c3-4149-bda5-abcedffadsf" -AppSecret "643r4er5sfdadsfadsfdsf=" -ReturnConnection

Write-Host  $sampleConnect.Url
In this example, I’m connecting to a Site Collection on my tenant.

Assumptions:
1) You have created a token in your o365 site
1.1) https://portal.office.com/account/
1.2) On the left site of the page click Security & privacy, then click Create and manage app passwords
1.3) In the app password page click the create button and give it a name.
1.4) Save the password to a secure location.
1.5) There is a better way of doing this that I will cover in a future post.
2) You have downloaded to CSOM DLL(s) from Nuget

Clear-Host

$userName = "me@sharepointed.com"
$pw = "abc123taco"  # I"M USING AN APP PASSWORD 
$siteCollectionUrl = "https://sharepointed.sharepoint.com/sites/taco"

#Secure the password
$securePassword = ConvertTo-SecureString $pw -AsPlainText -Force

Add-Type -Path "C:\Code\DLL\Microsoft.SharePoint.Client.dll"
Add-Type -Path "C:\Code\DLL\Microsoft.SharePoint.Client.Runtime.dll"

#Create Context
$ctx = New-Object Microsoft.SharePoint.Client.ClientContext($siteCollectionUrl)

#Authorise
$ctx.Credentials = New-Object Microsoft.SharePoint.Client.SharePointOnlineCredentials($userName, $securePassword)

$web = $ctx.Web
$properties = $web.AllProperties
$ctx.Load($web)
$ctx.Load($properties)
$ctx.ExecuteQuery()

Write-Host " Site Collectione URL: $($web.Url)"
Write-Host "Properties are "

foreach ($prop in $properties) {
    $prop.FieldValues
}
