Error in file(con, "r") in R reading a txt file using an URL-CodePudding

I am looking to read a .txt file from a URL. I run the following:

readLines(paste0("https://www.sec.gov/Archives/", All_file_today[Var], sep = ""))

Given that All_file_today[var] contains the following Url: 'edgar/data/99189/0001567619-22-004329.txt'

But it returns the error:

Error in file(con, "r") : 
  cannot open the connection to 'https://www.sec.gov/Archives/edgar/data/99189/0001567619-22-004329.txt'

When i copy this weblink and paste it in a web browser, it shows the content that I am looking for just clear. Anyone knows what i am not doing right please ?

Following the feedback from Nad below, I run the following:

> res <- GET(url, add_headers(`User-Agent` = user, Connection = 'keep-alive'))
> res

From the above, I understand that I am able to get to the file, but the readLines does not go through. What could be the reason please ?

CodePudding user response：

We can read the file using package httr,

url = 'https://www.sec.gov/Archives/edgar/data/99189/0001567619-22-004329.txt' 

user <- paste('Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:98.0)',
            'Gecko/20100101 Firefox/98.0')

res <- GET(url, add_headers(`User-Agent` = user, Connection = 'keep-alive'))

readLines(content(res))
