`Async-graphql-actix-web`提供实现了`actix_web::FromRequest`的`GQLRequest`，它其实是QueryBuilder的包装，你可以调用`GQLRequest::into_inner`把它转换成一个`QueryBuilder`。

你需要把Schema传入`actix_web::App`作为全局数据。
|
|
|
|
|
|
|
|
|
|
|
|
```rust
|
|
|
|
|
|
async fn index(
|
|
|
|
|
|
schema: web::Data<Schema>,
|
|
|
|
|
|
gql_request: GQLRequest,
|
|
|
|
|
|
) -> web::Json<GQLResponse> {
|
|
|
|
|
|
web::Json(GQLResponse(gql_request.into_inner().execute(&schema).await))
|
|
|
|
|
|
}
|
|
|
|
|
|
|
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
|
|
## 订阅例子
|
|
|
|
|
|
|
|
|
|
|
|
```rust
|
|
|
|
|
|
async fn index_ws(
|
|
|
|
|
|
schema: web::Data<Schema>,
|
|
|
|
|
|
req: HttpRequest,
|
|
|
|
|
|
payload: web::Payload,
|
|
|
|
|
|
) -> Result<HttpResponse> {
|
|
|
|
|
|
ws::start_with_protocols(WSSubscription::new(&schema), &["graphql-ws"], &req, payload)
|
|
|
|
|
|
}
|
|
|
|
|
