Struct Query

pub struct Query<T>(pub T);

Extract and validate typed information from the request’s query.

For query decoding uses serde_urlencoded crate QueryConfig allows to configure extraction process.

Example

use actix_web::{web, App};
use serde::Deserialize;
use actix_web_validator::Query;
use validator::Validate;

#[derive(Debug, Deserialize)]
pub enum ResponseType {
    Token,
    Code
}

#[derive(Deserialize, Validate)]
pub struct AuthRequest {
    #[validate(range(min = 1000, max = 9999))]
    id: u64,
    response_type: ResponseType,
}

// Use `Query` extractor for query information (and destructure it within the signature).
// This handler gets called only if the request's query string contains a `id` and
// `response_type` fields.
// The correct request for this handler would be `/index.html?id=1234&response_type=Code"`.
async fn index(info: Query<AuthRequest>) -> String {
    format!("Authorization request for client with id={} and type={:?}!", info.id, info.response_type)
}

fn main() {
    let app = App::new().service(
        web::resource("/index.html").route(web::get().to(index))); // <- use `Query` extractor
}

impl<T> FromRequest for Query<T>

where T: DeserializeOwned + Validate,

Extract typed information from the request’s query.

Example

use actix_web::{web, App};
use serde::Deserialize;
use actix_web_validator::Query;
use validator::Validate;

#[derive(Debug, Deserialize)]
pub enum ResponseType {
    Token,
    Code
}

#[derive(Deserialize, Validate)]
pub struct AuthRequest {
    #[validate(range(min = 1000, max = 9999))]
    id: u64,
    response_type: ResponseType,
}

// Use `Query` extractor for query information (and destructure it within the signature).
// This handler gets called only if the request's query string contains a `id` and
// `response_type` fields.
// The correct request for this handler would be `/index.html?id=19&response_type=Code"`.
async fn index(web::Query(info): web::Query<AuthRequest>) -> String {
    format!("Authorization request for client with id={} and type={:?}!", info.id, info.response_type)
}

fn main() {
    let app = App::new().service(
       web::resource("/index.html").route(web::get().to(index))); // <- use `Query` extractor
}

fn from_request(req: &HttpRequest, _: &mut Payload) -> Self::Future

Builds Query struct from request and provides validation mechanism

type Error = Error

The associated error which can be returned.

type Future = Ready<Result<Query<T>, <Query<T> as FromRequest>::Error>>

Future that resolves to a Self.

fn extract(req: &HttpRequest) -> Self::Future

Create a Self from request head asynchronously.

impl<T: Ord> Ord for Query<T>

fn cmp(&self, other: &Query<T>) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl<T: PartialEq> PartialEq for Query<T>

fn eq(&self, other: &Query<T>) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl<T: PartialOrd> PartialOrd for Query<T>

fn partial_cmp(&self, other: &Query<T>) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

Tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

Tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

Tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

Tests greater than or equal to (for self and other) and is used by the >= operator.
