Module axum_valid::json

Support for Json<T>

Feature

Enable the json feature (enabled by default) to use Valid<Json<T>>.

Usage

1. Implement Deserialize and Validate for your data type T.
2. In your handler function, use Valid<Json<T>> as some parameter’s type.

Example

use axum::routing::post;
use axum::Json;
use axum::Router;
use axum_valid::Valid;
use serde::Deserialize;
use validator::Validate;
#[tokio::main]
async fn main() -> anyhow::Result<()> {
    let router = Router::new().route("/json", post(handler));
    axum::Server::bind(&([0u8, 0, 0, 0], 8080).into())
        .serve(router.into_make_service())
        .await?;
    Ok(())
}
async fn handler(Valid(Json(parameter)): Valid<Json<Parameter>>) {
    assert!(parameter.validate().is_ok());
}
#[derive(Validate, Deserialize)]
pub struct Parameter {
    #[validate(range(min = 5, max = 10))]
    pub v0: i32,
    #[validate(length(min = 1, max = 10))]
    pub v1: String,
}
