通过 ZE1E1D3D405731238E0480CAF12 从 Sharepoint 读取和写入 Excel 和 CSV 文件

Question

I am trying to read and write csv files in SharePoint.

mysite <- get_sharepoint_site(site_url="https://****.sharepoint.com/sites/Test/test.xlsx")

mysite <- get_sharepoint_site(site_url="https://****.sharepoint.com/:f:/Test/?!sue0De2rb"")

It is always showing some error: Loading Microsoft Graph login for default tenant Error in process_response(res, match.arg(http_status_handler), simplify): Not Found (HTTP 404). Failed to complete operation. Message: The provided path does not exist, or does not represent a site.

Loading Microsoft Graph login for default tenant Error in process_response(res, match.arg(http_status_handler), simplify): Not Found (HTTP 404). Failed to complete operation. Message: The provided path does not exist, or does not represent a site.

Does anyone know anything that can be done?

I already have a sync in my laptop who works however want to connect directly from SharePoint to automate the process, so I don't need to have my laptop on to read and write the files.

Answer 1

You need to login with AzureGraph before to get permissions

Something like that for instance if your want to connect with browser login:

# authenticate with AAD
# - on first login, call create_graph_login()
# - on subsequent logins, call get_graph_login()
gr <- create_graph_login()
#then
mysite <- get_sharepoint_site(site_url="https://****.sharepoint.com/sites/Test/test.xlsx")

Something like that for instance if your want to connect without browser:

tenant <-  Sys.getenv("tenant")
secret <- Sys.getenv("secret")
app <- Sys.getenv("app")

# authenticate with AAD
# - on first login, call create_graph_login()
# - on subsequent logins, call get_graph_login()
gr <- create_graph_login(tenant=tenant, app=app, password=secret)
mysite <- get_sharepoint_site(site_url="https://****.sharepoint.com/sites/Test/test.xlsx", auth_type="device_code")

How do you get this information may vary if it your company, you might want to talk to your IT team or maybe follow this guide Authenticating via Microsoft

Answer 2

I am not 100% sure from your question, but based on the get_sharepoint_site method it looks like you're using the Microsoft365R package.

If this is the case, then unfortunately you cannot do what you're trying to do.

I believe get_sharepoint_site can be used to get your Sharepoint site (ie, Test), but not to get files within that site (ie, Test/test.xlsx).

This is the meaning of the errors you're seeing — "path... does not represent a site".

Your best bet is probably to construct your own http requests to Microsoft's Graph API. Check the documentation to see what API endpoints are available - the get range and range update endpoints are probably worth looking at.
