Robert Lazarski resolved AXIS2C-1495.
-------------------------------------
Fix Version/s: 2.0.0
Resolution: Fixed
When processing POST requests with application/x-www-form-urlencoded
content type, the last character of parameter values was being truncated
(e.g., "100" became "10").
Root cause: axis2_http_transport_utils_on_data_request() subtracts 1
from the size parameter to reserve space for null terminator. The callers
were passing content_length, so only content_length-1 bytes were read.
Fix: Pass content_length + 1 so the full content_length bytes are read.
A unit test was added for this issue.
> An error found while receiving www-form-urlencoded parameter values sent by
> POST method in REST style.

> I have been writing my code using Axis2/c server to apply to my project from
> about a month ago.
> I found a strange bug, which I don't know whether it was occurred from me or
> from axis2/c server.
> Could you check this out for me?
>
> Situation is like this.
>
> I sent a HTTP request using IE with the code shown below.
>
>
> <html>
> <body>
> <form name="testPOST"
> action="http://localhost:9090/axis2/services/school/writeobject/scd/1";
> method="POST">
> Tag ID <input type="text" name="tagid"/><br/>
> Transaction ID <input type="text" name="transid"/><br/>
> Value<input type="text" name="value"/><br/>
> <input type="submit" value="transdata"><br/>
> </form>
> </body>
> </html>
>
> Let's assume that I inputted 1, 1, 100 for respective Tag ID, Transaction ID,
> and Value.
>
>
> On server side, when I look into the parameters using the below function in
> school_skeleton.c
>
> axiom_node_t *AXIS2_CALL
> school_invoke(
> axis2_svc_skeleton_t * svc_skeleton,
> const axutil_env_t * env,
> axiom_node_t * node,
> axis2_msg_ctx_t * msg_ctx)
> {
> ...
>
> axis2_char_t * pStrNode = axiom_node_to_string(node, env);
>
> }
>
>
> It shows like this.
>
> <...><tagid>1</tagid><transid>1</transid><value>10</value><...>
>
>
> Please make notice that <value>10</value> which is not correct, it should be
> <value>100</value>
> since I put 100 into Value param as shown above.
>
> I really don't know why the last character is trancated when params with
> xxx-form-urlencoded form are sent by POST.
> It does not problem when the GET method is used or xml data is sent to the
> axis2/c server.
> Only POST method parameters with xxx-form-urlencoded form are sent to Axis2/c
> server.
>
> Could you give a hint for me to resolve this problem? It really annoying me
> from a few days ago.
