FastCGI: get request headers

Question

Im currently working on a Web C ++ application using FastCGI with Apache and mod_fcgid.

I am trying to get request headers, but I have not found how to do this. After some research, I thought the headers were in the "envp" attribute of "FCGX_Request", but it contained environment variables such as:

REMOTE_ADDR: 192.168.0.50 SERVER_SOFTWARE: Apache/2.2.21 (Unix) mod_ssl/2.2.21 OpenSSL/1.0.0f DAV/2 mod_fcgid/2.3.6 REDIRECT_UNIQUE_ID: TxytP38AAAEAABpcDskAAAAE FCGI_ROLE: RESPONDER HTTP_ACCEPT_LANGUAGE: fr SERVER_SIGNATURE: <address>Apache/2.2.21 [etc.] 

These variables offer me useful information, but I need real HTTP headers, and especially Cookie. I tried to read FCGX_Request in stream "in", but it seems to be for the request body (POST data). Since my application is for multithreading, I use "FCGX_Accept_r ()", for example:

 while(true) { FCGX_Init(); FCGX_Request* fcgiRequest = new FCGX_Request; FCGX_InitRequest(fcgiRequest, 0, 0); if(FCGX_Accept_r(fcgiRequest) < 0) break; Request* request = new Request(fcgiRequest); request->process(); } 

But actually I do not use streams. Requests are executed one by one.

How to get request headers?

Thanks.

Try using the following code. It should print the whole environment so that you can find the variable you are looking for.

 while(true) { FCGX_Init(); FCGX_Request* fcgiRequest = new FCGX_Request; FCGX_InitRequest(fcgiRequest, 0, 0); if(FCGX_Accept_r(fcgiRequest) < 0) break; char **env = fcgiRequest->envp; while (*(++env)) puts(*env); Request* request = new Request(fcgiRequest); request->process(); }
