#includeIn this example, we define a `get_user` function that takes a `Request` and `Response` object as arguments. It extracts the "id" query parameter from the request, looks up the user data based on the ID, and returns a JSON response with the user data. We then define our endpoint with the `get()` method, passing in the path and the `get_user` function. Package library: It seems like the `cpp-webserver` package is used to provide the `Endpoint` class, and the `nlohmann/json` package is used for JSON serialization.#include using namespace cppe; using json = nlohmann::json; void get_user(Request& req, Response& res) { // Extract the "id" query parameter from the request std::string id = req.query_param("id"); // Look up the user data based on the ID json data = { {"id", id}, {"name", "John Doe"}, {"email", "[email protected]"} }; // Return the user data as a JSON response res.json(data); } int main() { Endpoint app; app.get("/users", get_user); app.listen(8080); return 0; }
