Struct rocket::serde::json::Json

source ·
#[repr(transparent)]
pub struct Json<T>(pub T);
Available on crate feature json only.
Expand description

The JSON guard: easily consume and return JSON.

§Sending JSON

To respond with serialized JSON data, return a Json<T> type, where T implements Serialize from serde. The content type of the response is set to application/json automatically.

use rocket::serde::json::Json;

#[get("/users/<id>")]
fn user(id: usize) -> Json<User> {
    let user_from_id = User::from(id);
    /* ... */
    Json(user_from_id)
}

§Receiving JSON

Json is both a data guard and a form guard.

§Data Guard

To deserialize request body data as JSON , add a data route argument with a target type of Json<T>, where T is some type you’d like to parse from JSON. T must implement serde::Deserialize.

use rocket::serde::json::Json;

#[post("/user", format = "json", data = "<user>")]
fn new_user(user: Json<User>) {
    /* ... */
}

You don’t need to use format = "json", but it may be what you want. Using format = json means that any request that doesn’t specify “application/json” as its Content-Type header value will not be routed to the handler.

§Form Guard

Json<T>, as a form guard, accepts value and data fields and parses the data as a T. Simple use Json<T>:

use rocket::form::{Form, FromForm};
use rocket::serde::json::Json;

#[derive(FromForm)]
struct User<'r> {
    name: &'r str,
    metadata: Json<Metadata>
}

#[post("/user", data = "<form>")]
fn new_user(form: Form<User<'_>>) {
    /* ... */
}

§Incoming Data Limits

The default size limit for incoming JSON data is 1MiB. Setting a limit protects your application from denial of service (DoS) attacks and from resource exhaustion through high memory consumption. The limit can be increased by setting the limits.json configuration parameter. For instance, to increase the JSON limit to 5MiB for all environments, you may add the following to your Rocket.toml:

[global.limits]
json = 5242880
