Download files from an URL

Dear all,

I wrote an function, which should download folder given in 'founded_medicine_folder.xls' as an url (see attachment). Unfortunately, I get an error, where it says:

'Error using fopen

First input must be a file name or a file identifier.

Error in download_edf>downloadFolderContentToCellArray

(line 31)

fileID = fopen(fileName, 'w');

Error in download_edf (line 2)

downloadFolderContentToCellArray(folderCellArrayData)'

1)What should I change that it considers the URL as an filename?

2) Can you observe if it would work?

folderCellArrayData = readcell('founded_medicine_folder.xls')
downloadFolderContentToCellArray(folderCellArrayData)

function downloadFolderContentToCellArray(folderCellArrayData)
    import matlab.net.http.*
    
    %add password, didn't want it to stay in code 
    creds = Credentials('Username', '', 'Password', ''); 
    options = HTTPOptions('Credentials', creds, 'ConnectTimeout', 60); 
    
    len = length(folderCellArrayData); 
    %TODO make it first line or someting and not a sudden magic number
    %currently first line descriptions of content
    %following two empty lines 
    for x = 1:len
        
       %filetype =  folderCellArrayData{x,3};
       url = folderCellArrayData{x,1};
       
       %if ~(strcmp(filetype, 'folder'))
           
        resp = RequestMessage().send(url , options); 
      
        %find file name
        i = strsplit(url, '/'); 
        y = length(i); 
        fileName = i(y); 
        
        
        %save file in temp folder
        fileID = fopen(fileName, 'w'); 
        fprintf(fileID, '%s', resp.Body.Data); 
        fclose(fileID);        
       %end 

        
    end 
end

Hi,

i = strsplit(url, '/'); 
y = length(i); 
fileName = i(y);

It seems that above lines of code makes the fileName variable to be of type cell array.

quick resolution would be to change type of fileName variable.

fileName = i{y}

Hope it helps.
