软件介绍
Pencil Framework 是一个 Rust 的微框架，其灵感来自于 Flask。
一个简单应用：
extern crate pencil;
use pencil::{Pencil, Request, Response, PencilResult};
fn hello(_: &mut Request) -> PencilResult {
Ok(Response::from("Hello World!"))
}
fn main() {
let mut app = Pencil::new("/web/hello");
app.get("/", "hello", hello);
app.run("127.0.0.1:5000");
}路由：
fn user(r: &mut Request) -> PencilResult {
let user_id = r.view_args.get("user_id").unwrap();
Ok(format!("user {}", user_id).into())
}
fn main() {
// app here
app.get("/user/<int:user_id>", "user", user);
}JSON 处理：
use std::collections::BTreeMap;
use pencil::jsonify;
fn app_info(_: &mut Request) -> PencilResult {
let mut d = BTreeMap::new();
d.insert("name", "hello");
d.insert("version", "0.1.0");
return jsonify(&d);
}
fn main() {
// app here
app.get("/info", "app_info", app_info);
}错误处理：
use pencil::HTTPError;
fn page_not_found(_: HTTPError) -> PencilResult {
let mut response = Response::from("Customized 404 :)");
response.status_code = 404;
Ok(response)
}
fn main() {
// app here
app.httperrorhandler(404, page_not_found);
}
