Sincere

Sincere is a micro web framework for Rust(stable) based on epoll and multithreadind. Here is an example of a simple application:

```rust extern crate sincere;

use sincere::App;

fn main() { let mut app = App::new();

app.get("/", |context| {
    context.response.from_text("Hello world!").unwrap();
});

app.run("127.0.0.1:9001", 20).unwrap();

} `` Don't forget add this to yourCargo.toml`:

toml [dependencies] sincere = "0.4" Build and run, then, visiting http://127.0.0.1:8000/, you will see Hello world on the screen.

Guide

Routing

```rust app.add("GET", "user", ...);s

app.get("/user", ...);

app.get("/user/{id:[0-9]+}", ...);

app.post("/user", ...);

app.put("/user/{id:[0-9]+}", ...);

app.delete("/user/{id:[0-9]+}", ...);

app.options("/", ...);

app.connect("/", ...);

app.head("/", ...);

```

Route Group

```rust use sincere::App; use sincere::Group;

fn main() { let mut app = App::new();

app.get("/", |context| {
    context.response.from_text("Hello world!").unwrap();
});

let mut user_group = Group::new("/user");

// /user
user_group.get("/", ...);
// /user/123
app.get("/{id:[0-9]+}", ...);

app.mount(user_group::handle);

app.run("127.0.0.1:8000");

} ```

```rust use sincere::App; use sincere::Group; use sincere::Context;

pub struct User;

impl User { pub fn list(mut context: &mut Context) { ... }

pub fn detail(mut context: &mut Context) {
    ...
}

pub fn handle() -> Group {
    let mut group = Group::new("/user");

    group.get("/", Self::list);
    group.get("/{id:[0-9]+}", Self::detail);

    group
}

}

fn main() { let mut app = App::new();

app.get("/", |context| {
    context.response.from_text("Hello world!").unwrap();
});

app.mount(User::handle());

app.run("127.0.0.1:8000");

} ```

Middleware

```rust use sincere::App;

fn main() { let mut app = App::new();

app.begin(|context| {
    ...
});

app.before(|context| {
    ...
});

app.after(|context| {
    ...
});

app.finish(|context| {
    ...
});


app.get("/", |context| {
    context.response.from_text("Hello world!").unwrap();
});

app.run("127.0.0.1:8000");

} ```

```rust ... app.begin(...).begin(...);

app.begin(...).finish(...);

app.begin(...).before(...).after(...).finish(...); ... ```

rust app.get("/", |context| { context.response.from_text("Hello world!").unwrap(); }).before(...).after(...);

```rust let mut group = Group::new("/user");

group.before(...).after(...);

group.get("/", |context| { context.response.from_text("Hello world!").unwrap(); }).before(...).after(...); ```

```rust pub fn auth(context: &mut Context) { if let Some(token) = context.request.getheader("Token") { match token::verifytoken(token) { Ok(id) => { context.contexts.insert("id".toowned(), Value::String(id)); }, Err(err) => { context.response.fromtext("").unwrap(); context.stop(); } } } else { context.response.status_code(401); context.stop(); } }

app.post("/article", ...).before(auth);

group.post("/", ...).before(auth);

```

```rust pub fn cors(app: &mut App) {

app.begin(move |context| {
    if context.request.method() == &Method::Options {
        context.response
        .status_code(204)
        .header(("Access-Control-Allow-Methods", "GET,HEAD,PUT,PATCH,POST,DELETE,OPTIONS"));

        context.stop();
    }
});

app.finish(move |context| {
    context.response
    .header(("Access-Control-Allow-Origin", "*"))
    .header(("Access-Control-Allow-Headers", "content-type, token"));
});

}

app.use_middleware(cors); ```

Path Parameters

```rust app.get("/user/{id}", |context| { let id = context.request.param("id").unwrap(); });

app.get("/user/{id:[0-9]+}", |context| { let id = context.request.param("id").unwrap(); });

app.get("/user/{id:[a-z0-9]{24}}", |context| { let id = context.request.param("id").unwrap(); }); ```

Query Parameters

/article?per_page=10&page=1

rust app.get("/article", |content| { let page = context.request.query("page").unwrap_or("1"); let per_page = context.request.query("per_page").unwrap_or("10"); });

Bind Json

```toml serde_derive = "1.0"

[dependencies.serdejson] version = "1.0" features = ["preserveorder"] ```

```rust

[macro_use]

extern crate serdederive; extern crate serdejson; ```

```rust app.post("/article", |content| {

#[derive(Deserialize, Debug)]
struct New {
    title: String,
    image: Vec<String>,
    content: String
}

let new_json = context.request.bind_json::<New>().unwrap();

// some code

let return_json = json!({
    "article_id": 123
});

context.response.from_json(return_json).unwrap();

}); ```

Get and set headers, http status code

```rust app.get("/", |context| { let token = context.request.header("Token").unwrapor("none".toowned());

context.response.from_text("Hello world!").status_code(200).header(("Hello", "World")).unwrap();

}); ```
