在redux中验证我的用户后，我应该如何验证我的套接字？

Question

onSubmit＆gt; userAction.login＆gt;发送“SUCCESS_AUTHENTICATE”＆gt;在reducers中设置用户和套接字状态的标记＆gt; ?????那我怎么能让socket.emit（“authenticate”，{token}）发生呢？

Answer 1

简单地编写一个简短的中间件，工作得很好。

const socketAuthenticator = (store) => (next) => (action) =>{
    if(action.type === "AUTHENTICATION_FULFILLED" || action.type === "REGISTRATION_FULFILLED") {
        const token = action.payload.token;
        const socket = store.getState().socket.socket
        socket.emit('authenticate', { token })
    }
    next(action)
}
