Warp

Async-graphql-warp提供了两个Filter，graphql和graphql_subscription。

graphql用于执行Query和Mutation请求，它提取 GraphQL 请求，然后输出一个包含async_graphql::Schema和async_graphql::Request元组，你可以在之后组合其它 Filter，或者直接调用Schema::execute执行查询。

graphql_subscription用于实现基于 Web Socket 的订阅，它输出warp::Reply。

请求例子

#![allow(unused)]
fn main() {
extern crate async_graphql_warp;
extern crate async_graphql;
extern crate warp;
use async_graphql::*;
use std::convert::Infallible;
use warp::Filter;
struct QueryRoot;
#[Object]
impl QueryRoot { async fn version(&self) -> &str { "1.0" } }
async fn other() {
type MySchema = Schema<QueryRoot, EmptyMutation, EmptySubscription>;

let schema = Schema::new(QueryRoot, EmptyMutation, EmptySubscription);
let filter = async_graphql_warp::graphql(schema).and_then(|(schema, request): (MySchema, async_graphql::Request)| async move {
    // 执行查询
    let resp = schema.execute(request).await;

    // 返回结果
    Ok::<_, Infallible>(async_graphql_warp::GraphQLResponse::from(resp))
});
warp::serve(filter).run(([0, 0, 0, 0], 8000)).await;
}
}

订阅例子

#![allow(unused)]
fn main() {
extern crate async_graphql_warp;
extern crate async_graphql;
extern crate warp;
use async_graphql::*;
use futures_util::stream::{Stream, StreamExt};
use std::convert::Infallible;
use warp::Filter;
struct SubscriptionRoot;
#[Subscription]
impl SubscriptionRoot {
  async fn tick(&self) -> impl Stream<Item = i32> {
    futures_util::stream::iter(0..10)
  }
}
struct QueryRoot;
#[Object]
impl QueryRoot { async fn version(&self) -> &str { "1.0" } }
async fn other() {
let schema = Schema::new(QueryRoot, EmptyMutation, SubscriptionRoot);
let filter = async_graphql_warp::graphql_subscription(schema);
warp::serve(filter).run(([0, 0, 0, 0], 8000)).await;
}
}
