From f4c20290509d7ed3a8fd5304577e7a4cc0b9d974 Mon Sep 17 00:00:00 2001 From: Mike Buland Date: Tue, 3 Apr 2007 03:49:53 +0000 Subject: Ok, no code is left in src, it's all in src/old. We'll gradually move code back into src as it's fixed and re-org'd. This includes tests, which, I may write a unit test system into libbu++ just to make my life easier. --- src/old/http.cpp | 377 +++++++++++++++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 377 insertions(+) create mode 100644 src/old/http.cpp (limited to 'src/old/http.cpp') diff --git a/src/old/http.cpp b/src/old/http.cpp new file mode 100644 index 0000000..df7dafe --- /dev/null +++ b/src/old/http.cpp @@ -0,0 +1,377 @@ +#include +#include +#include "http.h" +#include "hashfunctionstring.h" + +Http::Http( Connection *pConnection ) : hReqHeader( new HashFunctionString(), 100 ) +{ + pCon = pConnection; + nParseState = parseInit; +} + +Http::~Http() +{ + for( int j = 0; j < lStrings.getSize(); j++ ) + { + delete (std::string *)lStrings[j]; + } +} + +bool Http::parseRequest() +{ + for(;;) + { + pCon->readInput(); + switch( nParseState ) + { + case parseInit: + { + int nLen = pCon->scanInputFor( CR ); + if( nLen == -1 ) + { + return false; + } + else + { + nReqType = getRequestType( pCon->getInput() ); + pCon->usedInput( pCon->scanInputFor(' ')+1 ); + + nLen = pCon->scanInputFor(' '); + sReqURI.append( pCon->getInput(), nLen ); + pCon->usedInput( nLen+1 ); + + if( !strncmp( pCon->getInput(), "HTTP/", 5 ) ) + { + char mbuf[2]={'\0','\0'}; + unsigned char major, minor; + + pCon->usedInput( 5 ); + mbuf[0] = pCon->getInput()[0]; + major = (unsigned char)atoi(mbuf); + mbuf[0] = pCon->getInput()[2]; + minor = (unsigned char)atoi(mbuf); + setRequestVersion( major, minor ); + if( checkRequestVer() ) + { + nParseState = parseHeader; + } + else + { + setResponseStatus( statusHTTPVersionNotSupported ); + //printf("Verson not supported.\n"); + return true; + } + + pCon->usedInput( 5 ); + } + else + { + setResponseStatus( statusBadRequest ); + } + + //return false; + } + } + break; + + case parseHeader: + { + int nLen = pCon->scanInputFor( CR ); + //printf("nLen = %d: :::%s:::\n", nLen, pCon->getInput() ); + if( nLen == -1 ) + { + pCon->readInput( 1, 0); + } + else if( nLen == 0 ) + { + // We've got our double-newline, time for content. + pCon->usedInput( 2 ); + setResponseStatus( statusOK ); + return true; + } + else + { + nLen = pCon->scanInputFor(':'); + if( nLen == -1 ) + { + //printf("No colon?
