Detailed Description

HTTP_Client is intended to provide application API to classes that wish to do network i/o at a very high level of abstraction.

This class provides the ability to retrieve data from the network, of specified length and offset, and potentially use any protocol "under the hood" to do so. It currently uses HTTP. See HTTP_Handler also.

int TAO_HTTP_Client::open (  const ACE_TCHAR *  filename, const ACE_TCHAR *  hostname = ACE_DEFAULT_SERVER_HOST, u_short  port = 80 )

int TAO_HTTP_Client::read (  ACE_Message_Block *  mb  )

Starts a connection, and reads a file from the server into Message_Block mb Definition at line 32 of file HTTP_Client.cpp. References ACE_ERROR_RETURN, TAO_HTTP_Handler::byte_count(), ACE_Connector< TAO_HTTP_Handler, ACE_SOCK_CONNECTOR >::connect(), and LM_ERROR. Referenced by TAO_HTTP_Parser::parse_string(). { // Create a HTTP_Client Reader TAO_HTTP_Reader HTTP_reader (mb, this->filename_); TAO_HTTP_Handler *brp = &HTTP_reader; // Connect to the server if (connector_.connect (brp, this->inet_addr_) == -1) { ACE_ERROR_RETURN ((LM_ERROR, "%p\n", "TAO_HTTP_Client::read(): Connector error\n"), -1); } return HTTP_reader.byte_count (); }
