Hi all

I'm downloading an archive using the gb.net.curl HttpClient object
Like the code below…


In the _Read() event i can get the download size but i can't find a way to get the file size before downloading.
I tried the HttpClient.Head() method but the list of headers did not have Content.Length ?
A bit puzzled.

And help appreciated
Bruce

I have tried a few things, but I can't get the result you are looking for. If it helps there is a 'Size' property in 'Download' but I can't get it to work.

Thanks Charlie.
I'd suspect that Size property is just downloaded not total size.

Puzzling.

Code

Use the -I option to only retrieve the headers, and look for the “Content-Length” header. Add the -L option if necessary to follow redirects. For example:

$ curl -L -I https://cdimage.debian.org/debian-cd/current/amd64/iso-cd/debian-9.4.0-amd64-netinst.iso

It help yes but not as i'd hoped.
using curl -I i read the headers for the file in question (the gambas source archive)
https://gitlab.com/gambas/gambas/-/archive/master/gambas-master.zip
the header list i got was something i had also managed to view using httpclient but did not see any content-length info.

and Benoit says this on the M/l..

Benoit said

Content-Length is not a mandatory header. So if it is not present, you
can't know by advance the size of the download.

so looks to me like the file i am trying to get the size of is one of those that does not report it .

Sigh , oh well.

Thanks for the help guys

 Hey Charlie.
Just an observation.

Line 8 on my first post does not show as i wrote it.

written it is just
Dim sZip As String = "the/url/to/fie"

the post shows href= and class= stuff that should not be there.

Just a note m8. dunno if it anything to do with you or not.
Bruce.

Hi Bruce,

Not sure what the issue is/was, seems OK to me or have I missed something?

Code (gambas)

1. Dim sZip As String = "the/url/to/fie"

No the first post,  not the last where i typed a url so it could be seen as it is supposed to look.
the first where it is wrong.

Ahh yes, we have run into this before. I have corrected your first post. You need to add this: -
