Using plus sign in decodeURIComponent ('+')

Hello community,

I am having an issue with decodeURIComponent. Seems that it ignores "+" sign in a string.

I have this string

"https://stracloud.sharepoint.com/sites/Jakub/Shared%20Documents/Aplikace/Microsoft%20Forms/plus%20makes%20+%20problems.jpg"
 
after decoding
"plus" disappears and is replaced with " " so there are 3 spaces right now
https://stracloud.sharepoint.com/sites/Jakub/Shared Documents/Aplikace/Microsoft Forms/plus makes   problems.jpg
 
decodinguricomponent works fine in chrome console with "+" sign.
 
Any ideas?

Hi

If I have understood correctly, you want to extract the filename from the URL, so the filename
Plus%20makes%20+%20problems.jpg is returned as Plus makes + problems

Here is one method using "Send an HTTP request to SharePoint" action to retrieve the actual filename:

Copy-and-paste the following:

_api/web/GetFileByServerRelativeUrl('@{uriPath(variables('filePath'))}')/Name/$Value

"+" has a special meaning in urls. It's an encodig for a space. Therfore function decodeUriComponent() works as expecrted (imho).

You can solve your issue by replacing "+" with "%2B" before decoding:

decodeUriComponent( replace( outputs('Compose'), '+', '%2B' ) )
