Shortest code to post a string to WebServer

Question

In bash, this code posts String to post to http://www.example.com/target:

curl -d "String to post" "http://www.example.com/target"

NOTE: You should use http://www.example.com/target as the URL to POST to, without any change.

I think all other languages that I have knowledge in need a lot more code than this. I'm not blaming other languages. Let's see the interesting answers that reduce the effort.

Your task is to write the shortest code possible to send a POST request to a sample server, http://www.example.com/target, and the request data should be the string String to post.

Answer 1

Bash: 90 characters

No external tools, just pure bash.

echo 'POST /target HTTP/1.0
Content-length:14

String to post'>/dev/tcp/www.example.com/80

Answer 2

Rebol (51 chars)

write http://www.example.com/target"String to post"

Above works in Rebol 3. Below is a Rebol 2 version (63 chars):

read/custom http://www.example.com/target[post"String to post"]

iwr http://www.example.com/target -b "String to post"-me 3

Answer 8

PHP - 100 bytes

<?fwrite(fsockopen('www.example.com',80),'POST /target HTTP/1.0

String to post');

I apologize for any similarities to manatwork's bash solution, but I believe that this is the shortest way to do it.

Answer 13

Python 2: 80 chars

Just using the standard library:

import urllib2 as u
u.urlopen("http://www.example.com/target","String to post")

For an extra char, you can make the import less unusual.

import urllib2
urllib2.urlopen("http://www.example.com/target","String to post")

Batch/Powershell - 118 Chars

If you need to post from a Windows batch file or avoid changing ExecutionPolicy:

powershell -Command "(New-Object Net.WebClient).UploadString('http://www.example.com/target', 'p1=String%20to%20Post')"

Answer 18

PHP, 198 bytes

This is shamefully large...:

<?fopen('http://www.example.com/target','rb',0,stream_context_create(array('http'=>array('method'=>'POST','header'=>'Content-Type: application/x-www-form-urlencoded','content'=>'String to post'))));

At least I answered!

Answer 19

Bash, 69 bytes

lwp-request -m POST -b http://www.example.com/target "String to post"

You can read about the lwp-request command here: http://linux.about.com/library/cmd/blcmdl1_POST.htm

I think that the answer given by @manatwork is a much more neat and compatible version.
