示例1: getCurrentUrl
// . the url being reuqested
// . removes &code= facebook cruft
bool HttpRequest::getCurrentUrl ( SafeBuf &cu ) {
// makre sure we got enough room
if ( ! cu.reserve ( m_hostLen + 64 + m_plen + 1 + 1 ) ) return false;
// need a "Host: "
char *host = m_host;
if ( ! host ) host = APPSUBDOMAIN;
cu.safePrintf("http");
if ( m_isSSL ) cu.pushChar('s');
cu.safePrintf("://%s",host);
char *path = m_path;
long plen = m_plen;
if ( ! path ) {
path = "/";
plen = 1;
}
// . scan path and change \0 back to = or &
// . similar logic in HttpServer.cpp for logging!
char *dst = cu.getBuf();
char *src = path;
char *srcEnd = path + plen;
char dd = '=';
for ( ; src < srcEnd ; src++ , dst++ ) {
*dst = *src;
if ( *src ) continue;
*dst = dd;
if ( dd == '=' ) dd = '&';
else dd = '=';
}
*dst = '\0';
// cut it off at facebook's &code=
char *buf = cu.getBufStart();
char *code = strstr( buf,"&code=");
// fix for eventguru.com/blog.html?code=
if ( ! code ) code = strstr(buf,"?code=");
// hack that off if there
if ( code ) {
*code = '\0';
dst = code;
}
// update length
cu.setLength( dst - cu.getBufStart() );
return true;
