A Routerify utility library to generate JSON response.
In Success case, It generates JSON response in the following format:
{
"status": "success",
"code": "<status_code>",
"data": "<data>"
}In Failed case, It generates JSON response in the following format:
{
"status": "failed",
"code": "<status_code>",
"message": "<error_message>"
}Add this to your Cargo.toml:
[dependencies]
routerify = "3"
routerify-json-response = "3"use hyper::{Body, Request, Response, Server, StatusCode};
// Import required routerify_json_response methods.
use routerify_json_response::{json_failed_resp_with_message, json_success_resp};
use routerify::{Router, RouterService};
use std::net::SocketAddr;
async fn list_users_handler(_: Request<Body>) -> Result<Response<Body>, routerify_json_response::Error> {
// Fetch response data from somewhere.
let users = ["Alice", "John"];
// Generate a success JSON response with the data in the following format:
// { "status": "success", code: 200, data: ["Alice", "John"] }
json_success_resp(&users)
}
async fn list_books_handler(_: Request<Body>) -> Result<Response<Body>, routerify_json_response::Error> {
// Generate a failed JSON response in the following format:
// { "status": "failed", code: 500, data: "Internal Server Error: Couldn't fetch book list from database" }
json_failed_resp_with_message(
StatusCode::INTERNAL_SERVER_ERROR,
"Couldn't fetch book list from database",
)
}
// Create a router.
fn router() -> Router<Body, routerify_json_response::Error> {
Router::builder()
// Attach the handlers.
.get("/users", list_users_handler)
.get("/books", list_books_handler)
.build()
.unwrap()
}
#[tokio::main]
async fn main() {
let router = router();
// Create a Service from the router above to handle incoming requests.
let service = RouterService::new(router).unwrap();
// The address on which the server will be listening.
let addr = SocketAddr::from(([127, 0, 0, 1], 3001));
// Create a server by passing the created service to `.serve` method.
let server = Server::bind(&addr).serve(service);
println!("App is running on: {}", addr);
if let Err(err) = server.await {
eprintln!("Server error: {}", err);
}
