Struct QueryStringConfig

pub struct QueryStringConfig { /* private fields */ }

QueryString extractor configuration

Example

use actix_web::{error, web, App, FromRequest, HttpResponse};
use serde::Deserialize;
use serde_querystring_actix::{QueryString, QueryStringConfig, ParseMode};

#[derive(Deserialize)]
struct Info {
    username: String,
}

/// deserialize `Info` from request's querystring
async fn index(info: QueryString<Info>) -> String {
    format!("Welcome {}!", info.username)
}

fn main() {
    let app = App::new().service(
        web::resource("/index.html").app_data(
            // change query extractor configuration
            QueryStringConfig::default()
                .parse_mode(ParseMode::Brackets) // <- choose the parsing mode
                .error_handler(|err, req| {  // <- create custom error response
                    error::InternalError::from_response(
                        err, HttpResponse::Conflict().finish()).into()
                })
            )
            .route(web::post().to(index))
    );
}
