# 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 ```rust # 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; 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 ```rust # 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 { # 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; # } ``` ## 更多例子 [https://github.com/async-graphql/examples/tree/master/warp](https://github.com/async-graphql/examples/tree/master/warp)
