Hi,all, I write a MMS client,send a http POST request to MMSC,now I ONLY know my MMSC url is MMSC.stdServer.com and my wap gateway(10.0.0.123:9201), in gerneral, I send post as the following step:
POST mmsc.stdserver.com/cgi/.../.../postrequest.asp http1.1
but i don't know what /cgi/.../.../ is, so What should I send the wsp-POST to MMSC server?
thanks a lot.

You should ask your operator for MMSC url.
If CMCC, it's "mmsc.monternet.com".

This is a http post sample( for http header):

POST / HTTP/1.1
Content-Type: application/vnd.wap.mms-message
Content-Length: 23738
User-Agent: Javam1.4.0_01
Host: mmsc.monternet.com
Accept: text/html, image/gif, image/jpeg, *; q=.2, */*; q=.2
Connection: keep-alive
...

This a wsp_post:
URL="mmsc.monternet.com"
Content-Type: application/vnd.wap.mms-message
...

thanks ylcp97,
yes, now i use CMCC whose gateway is 10.0.0.172:9201, and I use http1.1 as the following step:
1.Create a gprs connection (APN:cmwap) success!
2. create a socket( af_inet,SOCK_STREAM,0); succ
3. connect(10.0.0.172,9201), timeout!!!! why?
4. send( "CONNECT mmsc.monternet.com http1.1 \r\n")
5. send ("POST / HTTP/1.1
Content-Type: APP/vnd.wap.mms-message
Content-Length: 23738
Host: mmsc.monternet.com
....")
the step above about send mms is RIGHT? would you please tell me in detail? I can contact you by email? (my email is: tiger_mail@sina.com) thanks a lot.

Are you sending your POST command with HTTP or WSP?
WAP only supports UDP.

You should have a WAP stack on the top of ip/udp.

Hi,ylcp97
thanks for your quickly reply!
yes, i'm sending POST command. I hear that WSP-CONNECT to wap gateway is required before sending POST command,so I do this. now I get a reply from wap gateway like this: 20 CF 4E 01, do you know it? thanks again.

You should set the url to "http://mmsc.monternet.com", not "mmsc.monternet.com http1.1 \r\n", if connecting to W/G via WSP.

It is seemed that you can not connect to a W/G via TCP/IP/HTTP. You may connect to MMSC's VASP on a contract with the operator, if you want to send MM messages via TCP/HTTP.

yes, i want send mm. if want to connect VASP( what's VASP ?), is it a need that I connect VASP with WSP-Connect before send WSP-POST request?
thanks .

Hi, if operator use SMTP instead of HTTP, is my thought right?
