每当使用 redux-saga 的实时套接字上出现响应时,我都会尝试调度一个操作。 我已经能够到达应该放置(调度)操作的代码行,但仅在这种实时套接字情况下,实时操作不会调度。
这是我的代码:
export function* watchEditorAcceptInvitatioRequest(action) {
yield takeEvery(START_EDITOR_ACCEPT_INVITATION_SOCKET, edditorAcceptInvitationSocket)
}
export function* edditorAcceptInvitationSocket(action) {
const {token, user_id} = action.payload
const subscription = SocketIo.subscribe(token, '/broadcasting/authTest')
yield put(listenEditorAcceptInvitationSocket())
let result = yield call(SocketIo.listen, subscription, `new-test-channel.${user_id}`,
'.new-test-test', (response) => edditorAcceptInvitationReceived({
func: receiveEditorAcceptInvitationSocket,
response: response
}))
}
export function* edditorAcceptInvitationReceived(action) {
while(true) {
console.log(action.response) // I am seeing this in response but the action put in blow line
yield put(action.func(action.response))
}
}
下面是socket订阅和监听代码:
import Echo from 'laravel-echo'
import Socketio from 'socket.io-client'
const BASE_URL = 'https://www.my domain.com'
const PORT = 1111
const subscribe = (token, authEndpoint) => new Echo({
broadcaster: 'socket.io',
host: `${BASE_URL}:${PORT}`,
client: Socketio,
authEndpoint: authEndpoint,
auth: {
headers: {
Authorization: 'Bearer ' + token,
Accept: 'application/json',
},
},
})
const listen = (echo, channel, event, callback) => {
echo.private(channel).listen(event, e => {
const generator = callback(e)
generator.next()
})
}
export default {
subscribe,
listen
}
这里缺少什么,任何帮助将不胜感激。
最佳答案
我能够通过eventChannel解决这个问题
上面示例的工作代码是:
export function* watchEditorAcceptInvitatioRequest(action) {
yield takeEvery(START_EDITOR_ACCEPT_INVITATION_SOCKET, edditorAcceptInvitationSocket)
}
export function* edditorAcceptInvitationSocket(action) {
const {token, user_id} = action.payload
const subscription = SocketIo.subscribe(token, '/broadcasting/authTest')
yield put(listenEditorAcceptInvitationSocket())
let channel = yield call(SocketIo.listen, subscription, `new-test-channel.${user_id}`,
'.new-test-test', receiveEditorAcceptInvitationSocket)
while (true) {
const action = yield take(channel)
yield put(action)
}
}
下面是更新的套接字订阅和监听代码:
从“../store/configureStore”导入商店 从“laravel-echo”导入 Echo 从“socket.io-client”导入 Socketio 从 'redux-saga' 导入 {eventChannel}
const BASE_URL = 'https://www.my domain.com'
const PORT = 1111
const subscribe = (token, authEndpoint) => new Echo({
broadcaster: 'socket.io',
host: `${BASE_URL}:${PORT}`,
client: Socketio,
authEndpoint: authEndpoint,
auth: {
headers: {
Authorization: 'Bearer ' + token,
Accept: 'application/json',
},
},
})
const listen = (echo, channel, event, callback) => {
return eventChannel( emitter => {
echo.private(channel).listen(event, e => {
emitter(store.dispatch(callback(e)))
})
return () => {
console.log('returning channel')
}
})}
export default {
subscribe,
listen
}
