即使在模式中定义了突变,它也不会广播,我还在 Subscription 字段类中添加了一些日志消息,但是如果我通过突变或从工匠修补程序触发订阅,如下所示:
>>> Nuwave\Lighthouse\Execution\Utils\Subscription::broadcast('messageSent', $m);
=> null
什么都没有发生,没有日志,推送器仪表板中没有任何显示。我使用 laravel graphql 游乐场来收听广播消息,如下所示:
subscription {
messageSent {
id
text
}
}
每次我连接到广播时,我都会在浏览器中收到此控制台错误
client.js:547 Uncaught Error: Invalid message type!
at e.processReceivedData (client.js:547)
at WebSocket.client.onmessage (client.js:485)
这出现在 Pusher 仪表板错误日志中 - 缺少参数:事件。连接时出现两次错误,断开连接时出现一次。
我也没有在突变响应中获得任何订阅频道:
...
"extensions": {
"lighthouse_subscriptions": {
"version": 1,
"channel": null,
"channels": []
}
}
这是我的架构:
type Subscription {
messageSent: Message!
@subscription(class: "App\\GraphQL\\Subscriptions\\MessageSent")
}
extend type Mutation {
sendMessage(input: SendMessageInput! @spread): Message
@guard
@inject(context: "user.id", name: "sender_id")
@create
@broadcast(subscription: "messageSent")
...
这是 MessageSent php 类
namespace App\GraphQL\Subscriptions;
use Illuminate\Http\Request;
use Nuwave\Lighthouse\Subscriptions\Subscriber;
use Nuwave\Lighthouse\Schema\Types\GraphQLSubscription;
class MessageSent extends GraphQLSubscription
{
public function authorize(Subscriber $subscriber, Request $request): bool
{
info("authorize");
return true;
}
public function filter(Subscriber $subscriber, $root): bool
{
info("filter");
return true;
}
}
