示例1: get_request_path
std::string get_request_path(request &req) {
const char *request_uri = req.get_param("REQUEST_URI");
if ((request_uri == NULL) || (strlen(request_uri) == 0)) {

// the former is set by fcgi, the latter by Rack.

}
if ((request_uri == NULL) || (strlen(request_uri) == 0)) {
ostringstream ostr;
ostr << "request didn't set either the $REQUEST_URI or $PATH_INFO "
"environment variables.";
throw http::server_error(ostr.str());
}
const char *request_uri_end = request_uri + strlen(request_uri);
// i think the only valid position for the '?' char is at the beginning
// of the query string.

}示例2: get_query_string
string get_query_string(request &req) {
// try the query string that's supposed to be present first
const char *query_string = req.get_param("QUERY_STRING");
// if that isn't present, then this may be being invoked as part of a
// 404 handler, so look at the request uri instead.
if (query_string == NULL) {

if ((request_uri == NULL) || (strlen(request_uri) == 0)) {
// fail. something has obviously gone massively wrong.

}示例3: choose_encoding
/**
* get encoding to use for response.
*/

} else {

}
}示例4: fcgi_get_env
string fcgi_get_env(request &req, const char *name, const char *default_value) {
assert(name);
const char *v = req.get_param(name);
// since the map script is so simple i'm just going to assume that
// any time we fail to get an environment variable is a fatal error.
