Library: omhttp - HTTP support Include: omhttp.xin

Declaration

  define function HttpServiceAwaitRequest
                 value       TCPService    Service
     receive     modifiable  stream        Request
     connection  modifiable  TCPConnection Connection
     timeout     value       integer       Timeout optional initial {10000}
     decode-search-plus value switch Decode-Search-Plus optional initial {false}

  where

Service

is the TCP service.

Connection

is a TCP connection object that is the connection between the server and client (output argument).

Request

is the HTTP response object containing data to send to the client (output argument).

Timeout

is the maximum number of milliseconds to wait for a communication operation before failing (input argument).

Decode-Search-Plus

is an instruction on whether to decode "+" characters to spaces in the search part of the URL. The use of "+" characters to represent spaces is not part of the HTTP standard, but is common practice in many browsers. To decode "+" characters as spaces, specify a "true" switch value for Decode-Search-Plus (input argument).

Use HttpServiceAwaitRequest to wait on the specified TCP service until an HTTP request is received. The HTTP request object is populated from the received message and passed on to the rest of the program for processing to create an HTTP response object. HttpServiceAwaitRequest occurs in a server program.

Requirements

You must include the following line at the beginning of your OmniMark program:

  include "omhttp.xin"

Usage Notes

Service is set to an error state if the TCP communication times out. The timeout is only enforced after the client establishes a connection.

Connection is set to an error state if the TCP communication times out.

Example

  ; HttpServiceAwaitRequest
  include "omhttp.xin"

  process

  local TCPService my-Service
  local TCPConnection client-Connection
  local HttpRequest new-Request

  set my-Service to TCPServiceOpen at 1080

  HttpServiceAwaitRequest
     my-Service receive new-Request connection client-Connection timeout 30000
