CURL fails to send post data over 1024 bytes via command line

Question

I am trying to post a large XML file to a web address by using curl in a shell script. I am posting the data using the '-F' option in curl. Whenever I post a file larger than 1024 bytes, the file gets cut off and only sends the first 1024. I've tried changing the "Expect:" header as suggested in another solution for PHP Curl, but it does not work.

Here is the command line I am using:

curl -F "xml=</fileoutput.xml" http://servername/page.html

As I said earlier, I've tried both -H "Expect:" -H "Expect: 100-continue"

Neither work. Please help!

Answer 1

Is it possible that the web address itself has this limitation? Have you tried posting the same file manually via a web browser?

Answer 2

I think you need to use -d instead of -f ?

-d seems to post the data. As Sab pointed out GET has a very small maximum size, you must post the file and to do this you must use -d rather than -f.

Look here.

Answer 3

According to the man page the -F option does do POST so it doesn't look like it's a GET issue. The man page also says to prefix the file with an @ to use the file as the content so perhaps the command should be

curl -F xml=@http://servername/page.html

Answer 4

In order to poast a file you have to use the @ in front of the URL. I think Troubadour already mentions this, but it needs to be in quotes like:

 curl -F "xml=@http://servername/page.xml"

Also notice That I changed it to .xml as you said you were trying to post a large XML file, not a large HTML file.
