As in:

The cgicc::FormEntry class provides methods for extracting data 
as numbers, removing line breaks, etc. If you are not interested 
in performing any data validation or modification, but simply 
want to access a string representaion of the data, the simplest 
case is streamlined:

std::string name = cgi("name");


Maybe you are looking at an earlier version as I pointed you to 
the reference for said operator().

Hope it helps.

it is in the http://www.gnu.org/software/cgicc/doc/cgicc_tutorial.html
I look up the constructs,and didn't the usage.and there isn't a operator()
is the cgi class....

What is cgi?  If an instance of cgicc::Cgicc then it's invoking:

std::string operator() (const std::string &name) const
 Find a radio button in a radio group, or a selected list 
item

<http://www.gnu.org/software/cgicc/doc/classcgicc_1_1Cgicc.html> 
is where you find the reference.

cgi("name");

hang yan — 2012-03-26T08:56:15

std::string name = cgi("name");
I found it in the tutorial.but i don't understant how it workes.

Thx for the offer. In the mean time I've found the right compile-link commands and libs:
Under Linux (here Debian) one should install the following packages:
   libcgicc-dev
   libcgicc-doc
   libfcgi-dev

# cd /usr/share/doc/libcgicc-doc/examples/contrib/
# ls -l
-rw-r--r-- 1 root root 1870 Nov 14  2009 FCgiIO.cpp
-rw-r--r-- 1 root root 1476 Nov 14  2009 FCgiIO.h.gz

-rw-r--r-- 1 root root 2415 Nov 14  2009 nph-login.cpp.gz

Build:
   g++ -o fcgi-test.cgi  fcgi-test.cpp FCgiIO.cpp -lfcgi++ -lfcgi -lcgicc

Now it compiles and links fine.
But I have not tested it yet as I'm concentrating myself on SCGI.
Maybe the above info can be useful for others interested in FastCGI and cgicc.

Many years ago I had no problems linking fcgi-test.cpp

It's far much reliable to start external clients than to rely on
running anything inside of any server (php included). All depends on
the task. If you want something rock solid - do not run it inside of HTTP server.
Apache itself has many subtle problems with threads, forks, DOSes, I/O read writes,
keep alives etc.

We've been using Fast CGI servers for years and years, it's a
very reliable and fast solution.

If you're using fastcgi or scgi correctly you never have to handle
the low level underling protocol. Everything is the same as you're using CGI
application. You just don't have to forget that you're running a
service or daemon it never quits.

need a fastcgi wrapper, 
especially on windows or other cross platforms solution.

e.g, the python flup (django used).

but, any else ?

To assemble you would need:

cgicc
http://www.gnu.org/software/cgicc/

libfcgi
http://www.fastcgi.com/drupal/

To run:

If you're planning to run fcgi-test.cpp with Apache -
mod_fastcgi
I'm not sure how fastcgi is implemented in nginx, but
something similar is sure there.

about CgiEnvironment and POSTDATA when usingmultiplexed FastCgi

Andrey Vul — 2010-12-21T09:58:20

In the CgiEnvironment constructor, it looks like it attempts to read all
of stdin.
FastCgi, however, chunks the stdin packets.

1) Is the read function, as defined in a subclass bridging a
multiplexing FastCgi with Cgicc, supposed to block until there
everything can be read, as done in the official FastCgi SDK's
FCGX_GetStr(FCGX_Stream*, char*, int)?
Or use EAGAIN / exceptions and wrap input->read in a for(;;)?
I'm using another FastCgi class because the fact that I'm threading
the processing means that multiplexing is the way to go to unleash the
performance of parallelism, and FCGX_* is not multiplexing-safe.
Note: the FastCgi instance class basically calls
std::string::append(input_buffer.end(), stdin_data, stdin_len). 
2) Is there an ability to limit the size of POSTDATA by using a function
hook? The non-virtuality of CgiEnvironment implies that implementing
this would require patch && make && sudo make install.

Note: I am not on the mailinglist. CC me when needed.

Hi Eduard,

just enumerate envp array like this:

static string penv(const char * const * envp)
{
    string retValue = "<PRE>\n";
    for ( ; *envp; ++envp)
    {
        retValue += *envp;
retValue += "\n";
    }
    retValue += "</PRE>\n";
return retValue;
}

string environmentData = penv(request.envp);

Cross building cgicc, getElements() app link error

John Faith — 2010-08-31T17:17:30

Hello,
I built cgicc 3.2.8 using 2009q1 CodeSourcery ARM tools in
OpenEmbedded which built fine.  I was able to build and run the app
code below, but when I enable the getElements() section, I get a
linker error:
  hello.cpp:(.text+0x198): undefined reference to
`cgicc::Cgicc::getElements() const'

, which seems odd since getElements) is defined as inline in
cgicc/Cgicc.h.  I built the same app for x86 using g++ 4.4.1 and it
linked and ran fine.  Not sure if this is an issue with g++ or cgicc,
or can be patched in cgicc.  Anyone see this before?

Thanks!
,
John


int main(int argc, char **argv)

    Cgicc cgi;

    //    cout << "Your name: " << **name << endl;
    //}

    return 0;
