Hello,


I' m trying to send a XML request (with some SOAP) to a server (more
exactly a web service) by telnet. I do:

*******************************************
$ telnet <serverIp> 8080

GET /wher/I/want/to/send/my/data/ HTTP/1.1 <ENT>
<ENT>
HTTP/1.1 400 Bad Request
Server: Apache-Coyote/1.1
Transfer-Encoding: chunked
Date: Sat, 29 Apr 2006 17:22:43 GMT
Connection: close

0

Connection closed by foreign host.
$
********************************************
(<ENT> = push on enter)

So i cant send my XML request .... When i try to use HTTP/1.0 instead
HTTP/1.1, server anwer me the html page associate to the webservice.

Of course, when i directly send the XML request, server returns me a bad
request....

So how to send an XML request to a server please ?


Thanks.

This is correct. You have just sent an invalid HTTP 1.1 request.
Remember, HTTP 1.1 requires a Host: header. Not only that, HTTP 1.1
servers are REQUIRED TO REJECT requests without the Host: header with a
400 Bad Request error. Thus the minimum request should be:

GET /wher/I/want/to/send/my/data/ HTTP/1.1\r\n
Host: serverIp:8080\r\n\r\n

This is also correct since HTTP 1.0 does not have any required headers.

Typically you'd need to do a POST request with the XML document/code as
part of the message body sent to the server:

POST /wher/I/want/to/send/my/data/ HTTP/1.0\r\n
Content-Length: 46\r\n
\r\n
<xml><code><sent>to server</sent></code></xml>

(sorry for the late, but server was down).

Thanks for your answer, I try it by doing this:

*************************************************
$ telnet <ip address> 8080
POST /wher/I/want/to/send/my/data/ HTTP/1.1\r\n
Content-Type: text/xml; charset=utf-8\r\n
SOAPAction: ""\r\n
Content-Length: 785\r\n
Expect: 100-continue\r\n
Host: <ip address>:8080\r\n
\r\n
<xml><code><sent>to server</sent></code></xml>

HTTP/1.1 400 Bad Request
Server: Apache-Coyote/1.1
Date: Sat, 06 May 2006 07:25:32 GMT
Connection: close

Connection closed by foreign host.
$
************************************************** *


But I' m not sure of the value of Content-Length. Is this the number of
character in the XML request ?

And maybe that my XML request is wrong. But server shouldn't send me
"data" to warn me that my request was wrong ?




Thanks.

Oops, I try request without \r\n, and its works fine.

Yes, \r in my post refers to Carrige Return and \n refers to Linefeeds
as per C convention. For \r\n configure your telnet client to have CRLF
line endings (LF works but is not really conformant to HTTP spec) and
press the Enter key (actually the Return key which is labelled Enter on
most PC keyboard. The "real" Enter key is actually the one on the
numeric keypad).

Ah ? But heuh... what is the difference between the Return key and the
"real" Enter key ? (just for my "general knowledge" :p )

For most applications, there's no difference.
