Hello,
Here is some abbreviated code from an http post that I am performing.
static const char buf[] =
"FILE_SIZE=3130&FILE_NAME=myfile.txt&TRANS_ID=123\nSome additional content";
curl_easy_setopt(curl, CURLOPT_POSTFIELDS, buf);
curl_easy_setopt(curl, CURLOPT_POST, 1);
curl_easy_perform(curl);
This works, and on the server side, I end up with a file on disk named
"myfile.txt" that contains "Some additional content". This is how the CGI
program operates, as expected. However, what I really want to do is to
transfer the contents of a large file (could be greater than 100Kbytes) instead
of the text "Some additional content". I could always read the file contents
into buf[] and transfer it in all in one operation. But I think that could
lead to performance issues, because the file to transfer can be arbitrarily
large. I know the server is expecting the payload to be in the same form as
buf[] above. What I would like to do is transfer it in chunks. First send the
"FILE_SIZE=3130&FILE_NAME=myfile.txt&TRANS_ID=123\n" portion, then send the
file contents split up into smaller pieces. I am fairly certain that the
server is expecting an HTTP Post.
This is probably a very simple thing to do, but I haven't found a way to get it
working.
I am working on RHEL 5.1, libcurl version 7.19.
Does anybody have any suggestions on how to do this?
Thanks,
Tim.
