cmake --build . --target installEvery role is provided an output stream by output(), an error stream by error() and request parameters by params(). For every incoming request from the web server a new role instance is created. Only one user specific role can be integrated for each type. Integration can look like this:
protocol.set_role<my_responder>();A detailed definition of the following roles can be found here.
A responder additionally receives optinal input by input(). This role has the same purpose as simple CGI/1.1 programs (this is probably what you want). A simple Hello, World might look like this:
#include <fast_cgi/fast_cgi.hpp>
class hello_world : public fast_cgi::responder
{
public:
status_code_type run() override
{
using namespace fast_cgi::manipulator;
output() << "Content-type: text/html" << feed << feed;
output() << "<html><body>"
<< "<h1>" << "Hello, World!" << "</h1><br/><br/>"
<< "<span>Here are all parameters:</span><br/>";
// Print all parameters
for (auto& i : params()) {
output() << i.first << "=" << i.second << "<br/>";
}
output() << "<span>Your payload:</span><br/>";
output() << input().rdbuf();
output() << "</body></html>"
return 0;
}
};More information can be found here.

See here.
Parameters can be iterated like:
for (auto& parameter : params()) {
std::cout << parameter.first << "=" << parameter.second << "\n";
}Getting a parameter (this example may throw an std::out_of_range exception if the key does not exist):
auto& value = params()["REQUEST_URI"];
// or
auto& value = params("REQUEST_URI");Checking if a parameter is available:
auto has_uri = params().has("REQUEST_URI");
