get data from a http POST request

ziong

hi all,
i wanna to ask that is it possible to get the raw data from a post request?
the full story is that i'm writing a php script to handle a post request from other.
i know that php will "track_vars" to the $HTTP_POST_VARS. However, the post data which is a message not in the format like "varname=value&varname2=...".
And now i can get the request header information from $HTTP_SERVER_VARS(CONTENT_LENGTH, CONTENT_TYPE, HOST... ), except the body.
So, how/is possible to get the request content?

anyone?

If you are running PHP as an apache module then you can use this getallheaders().

Thx for your reply.
Yes, i can get the header from this way, but still can't get the request body content.
The body content is the most i need.

I am trying to do something similar. I am sending XML to the server using JavaScript in IE. I want to retrieve the XML code at the server end using PHP, and I have tried both the suggestions in the reply to this request and neither work.
$HTTP_RAW_POST_DATA is empty, and getallheaders() just doesn't seem to return my XML code (although it does correctly return the content-length as 3814 bytes). Is there some trick I might be missing - is there some pre-requisite that is required to get either of the above suggestions working?
I haven't got the first clue as to what I need to do to extract the XML code from the HTTP header. If it helps, here is the JavaScript code at the client end:

xmlHttp = new ActiveXObject("Microsoft.xmlhttp");
xmlHttp.open('POST', 'submit_calendar.php', false);
xmlHttp.send(msXML.xml);

Thanks very much for any help you can give me,
Gary

hi
i used $HTTP_RAW_POST_DATA and it work very well. Are u sure that the post message is correct?
i guess that ur post message format is not correct. Since the message should be in 2 parts, header & content.
i guess that u only send the xml content without a correct header. Since php getallheaders() return nothing beside the content-length. Php just take ur xml content as the header of the post message, not the content of the message.

So i think u should do like that:
header = "......"; // the post message header
xmlHttp = new ActiveXObject("Microsoft.xmlhttp");
xmlHttp.open('POST', 'submit_calendar.php', false);
xmlHttp.send(header+msXML.xml);

if u don't know the header format, u can search in this forum.

Hi
Thanks for that - it turns out, however, that the send() method sends only the body, and there are separate functions for sending (certain limited) headers. Took me ages searching MSDN to find that out, after discovering that adding headers in the text sent in send() made no difference.

I just needed to add

xmlHttp.setRequestHeader("Content-Type", "text/xml");

before the send() method and suddenly $HTTP_RAW_POST_DATA had content!

maryphp

xmlHttp.setRequestHeader("Content-Type", "text/xml");

xmlMessage = buildSaveAddrData('sr');
xmlHttp.open("POST",url,true)

xmlHttp.send(xmlMessage)

I did above, and get an error:
xsxml3.dll unspecified error

where I should call
xmlHttp.setRequestHeader("Content-Type", "text/xml");
