Hello, because actually now crystal is in 1.2.2 version, I have a question. In past, HTTP::Client didn’t have the fonctionnality to do automatically redirections. And actually ? Because I would like to download a file with crystal and as well write a nice output when I’m downloading a file. For example showing percentage, amount of received data, progress bar …etc ---

I also don’t know if my information is up to date, but I’m pretty sure that HTTP::Client from standard library will _not_ handle redirects automatically. For a featureful HTTP client (that handles redirects) I recommend this one instead: > **[GitHub - icyleaf/halite: 💎HTTP Requests Client with a chainable REST API,...](https://github.com/icyleaf/halite)** > > 💎HTTP Requests Client with a chainable REST API, built-in sessions and middlewares. - GitHub - icyleaf/halite: 💎HTTP Requests Client with a chainable REST API, built-in sessions and middlewares. ---

Sorry to come back again to my old post, but any news about the redirects solutions for crystal ? I saw HTTP:Client didn’t implement that actually. Is halite the only available library actually for that ? If it’s not, just one question, how can I get the current network speed of download, amount of data transfered …etc ? ---

To handle [redirects](https://developer.mozilla.org/en-US/docs/Web/HTTP/Redirections) you can look at the response code and if it’s `301` or `302` then do another request to the location specified in the `Location` header. For the download speed you could use [Time.monotonic](https://crystal-lang.org/api/1.6.2/Time.html#monotonic%3ATime%3A%3ASpan-class-method) to calculate how much you download every second. ---

Hi ! Sorry I know I made this post long time ago. But I’m coming back because I found an another shard to have an HTTP client with redirections supports, and more updated. **I’m using Crest:** [GitHub - mamantoha/crest: HTTP and REST client for Crystal](https://github.com/mamantoha/crest) I did that to get the size of the downloaded data. Is it correct in that way ? Because network isn’t my speciality (this code is just a test): ```auto require "crest" startingTime = Time.monotonic currentTime = Time.monotonic Crest.get("https://www.kernel.org/pub/linux/kernel/v5.x/linux-5.13.12.tar.xz") do |resp| filename = resp.filename || "crystal.zip" while line = resp.body_io.gets if (currentTime - startingTime).seconds > 1 text = "crystal.zip | Received data: #{line.bytesize} bytes/seconde" print text print "\r" startingTime = Time.monotonic end currentTime = Time.monotonic end File.open(filename, "w") do |file| IO.copy(resp.body_io, file) end end ``` I have two questions as well. How can I get before my code download to get the downloaded filename and get the total size of the file ? For the filename, do I need to just extract it from the url ? I would like as well to know how much data are already downloaded. ---

Hi @Fulgurance . Maintainer of `crest` here. Regarding your question on how to retrieve the downloaded file’s filename and total size, you can do this by checking the response headers. Specifically, you can look for the “Content-Disposition” header to get the filename and the “Content-Length” header to get the total size. If you also want to track the amount of data downloaded, you can use this code. ```crystal require "crest" url = "https://github.com/crystal-lang/crystal/archive/1.8.1.zip" buffer_size = 4096 downloaded_size = 0 Crest.get(url) do |response| output_file = response.filename || "crystal.zip" File.open(output_file, "w") do |file| buffer = Bytes.new(buffer_size) loop do bytes_read = response.body_io.read(buffer) break if bytes_read == 0 file.write(buffer[0, bytes_read]) downloaded_size += bytes_read print "Received data: #{downloaded_size.humanize_bytes}" print "\r" end end puts puts "Download complete! Saved as #{output_file}" end ```
